OBS V Sub-Ohm Tank Review

The OBS V Sub-Ohm Tank is 26mm in diameter, and for this review I spent a week using it daily with the Limitless Arms Race box mod, the SMOK GX350, and the Lost Vape Triade DNA250 . In each case, the 26mm tank fits well, with no overhang. The proportions of the tank are such that in each case, the OBS V looked outstanding sitting atop the various mods.

The OBS V Sub-Ohm Tank is constructed with 304 Stainless Steel and glass. It’s available in Black, and ‘not-Black’ (Silver or Stainless Steel, depending on the vendor’s description.) with a juice capacity of 6mL. Interestingly, some vendors are stating a 5.2mL or 5.3mL juice capacity, and the official OBS website states 6mL. The capacity depends on the Coil Head used at the time, bear that in mind.

OBS includes 3 distinct coil-heads in the OBS V Sub-Ohm Tank package, the V12, the V8, and the V4.

The heating element (wire) is Kanthal A1, and the massive wicking is Organic Cotton. Optional Coils include a V10 OCC (Kanthal) and an RBA Head with a sizeable Two-Post Build Deck.

The package contents include a V12, V8, and a V4 coil head. Each of these, and the optional V10, are rated as followed:

  • 15ohm V12 OCC Core – rated for 60-150W, recommended 70-90W
  • 15ohm V10 OCC Core – rated for 60-100W,recommended 70-90W
  • 15ohm V8 OCC Core – rated for 90-180W,recommended 110-160W
  • 15ohm V4 OCC Core – rated for 120-260W, recommended 140-230W

All 4 coils are performance-orientated toward cloud production, using the “V OCC Coils System”. That said, The V12 is considered the “best cloud producer” Coil. The V8 and V4 are geared for a fuller flavor production, while still managing superlative clouds. The optional V10 OCC coil is said to be the best of both worlds, but if that were true, why make it optional? Why not substitute the V8 with the V10?

All four coil head options are rated 0.15Ω, and replacement coils come in 3-packs. As a huge fan of both the SMOK TFV8 and TFV12 tanks, I find it difficult to decide which of the two

The Smok TFV8 has a 6ml juice capacity like the OBS V Tank, and the Smok TFV12 has a 25mm “base” diameter as the OBS V tank. But when comparing the performance, both clouds and flavor, the OBS V Sub-Ohm comes close to the TFV12 Cloud Beast, with a few differences.

The OBS V Sub-Ohm and the SMOK TFV8/TFV12 Cloud Beasts

Filling and refiling the OBS V Sub-Ohm Tank is not obvious when it’s unboxed, but it is easy. This tank is a side-fill tank, and to reveal the side-fill slots pull up on the top cap. Filling the OBS V is easier than filling the TFV8/TFV12 Clouds Beasts.

Maximum Airflow of the OBS V Sub-Ohm Tank

The massive Airflow for the OBS V Tank is caused by a Quad-Air slots configuration at the base of the Tank. The Airflow of any tank aids in both cloud production and allowing a higher wattage setting for the mod used. If there is a single element of the OBS V that stands out immediately after the first use, it’s the enormous amount of air drawn in by a firm inhale when the airflow ring is set to wide-open. But there is a downside to this massive air flow system.

The OBS V Sub-Ohm Tank lets in more airflow than either of the SMOK TFV8  or TFV12 Cloud Beasts. The result of vaping the OBS V with maximum airflow is a thinner, or less full, cloud production than either of the Cloud Beasts set to wide open airflow.

To produce the same thickness of vapor the user must stop down the airflow some, and this can cause a range of whistling from minor to annoying. The are no ‘incremental’ stop downs in the airflow ring, but with some work you’ll find the positions that provide thick vapor with little to no whistling.

For my personal taste, in flavor and clouds, I prefer the V4 OCC Core. This V4 is rated for 120-260W, and is considered constructed for flavor production. I found my optimal vape at 145W for immense clouds and the best flavor of the 3 other coils.

That Dumb-Looking Drip Tip

Lastly, the OBS V Sub-Ohm Tank comes with two drip tips, both POM (Delrin) drip tips. Both are excellent at keeping cool no matter how much wattage is passing through the coils. The first is a normal looking wide-bore drip tip, the default drip tip when you open the box. The other drip tip is the tallest drip tip I’ve ever seen. This tall drip tip has a built-in heat sink, and the idea is that when using the V4 Core at near maximum wattage (230W) the heat doesn’t reach through that drip tip to burn the users’ lips.

While I vaped most of the time at 145W. I experienced no excessive heat from the normal wide-bore tip. Still, wanting to do a complete review, I did take the V4 Core  up to the 200W level while using the ridiculously tall drip tip and it works as advertised. I just don’t think many people will feel comfortable with this drip tip, unless the user is attempting a cloud chasing competition with the OBS V.


There is one element of the OBS V Sub-Ohm Tank that is an improvement over the SMOK TFV8

and TFV12 Sub-Ohm Tanks. The side-fill method is certainly an improvement, but from spending a full 7 days with both the OBS V Sub-Ohm with the V4 Core (and the other 3 coils) and the TFV12 Cloud Beast King with the V12-X4 Coil, I would have to give the edge to the TFV12 Cloud Beast King for flavor and cloud production. The competition was close, very close, so what it comes down to is the aesthetics of the two tanks.

More than a few people I know believe the TFV12 Cloud Beast King to be too big. For that reason alone, they won’t buy one or use one. This tank has a base size of 25mm, but the middle ‘glass’ size widens to 27mm, and the widest part of the tank is 28mm. The height of the Cloud Beast King is 70mm, making it a large Sub-Ohm tank.

The OBS V Sub-Ohm Tank is 26mm in diameter from top to bottom, with a height of 64mm. While the OBS Vis nowhere near a small tank, it is noticeably smaller in stature than the TFV12 Cloud Beast King.

For Sub-Ohm Vapers looking for something on par with the SMOK TFV8 and TFV12 models, the OBS V Sub-Ohm comes closest, at this point in time.

OBS V OCC Replacement Coils can be found here

Putting my bias to the side to grade the OBS V, I give this Sub-Ohm Tank a A.

SMOK QBOX Kit Review


Smok Q Box

SMOK QBOX TC Kit is small, but one thing for sure is that its functionality is undoubted. The device fits perfectly in the palm of your hand and features all the technological and stylish aspects you would expect a SMOK product to have. The small size doesn’t hinder it from emanating big vapor clouds and has a large LED screen to provide at a glance all the information on your device’s performance.

If you are a beginner in the mod vaping world, then this is a great way to begin your journey. It beautifully bridges the jump from e-cigarettes to box mods. Everything that you need is contained within this kit, including charger cable, spare coils, user manual to guide you and a TFV8 Baby Tank, in fact all you need is e-liquid and your good to go!

Whether your focus is on style or performance or want to combine the two, the SMOK Q-Box will give each vaper everything they need and more. Making it one of the best box mods on the market for it’s size.

Smok Q BOX

Fast Charging Capability, Huge Clouds

The QBOX TC features a 1600 mAh rechargeable battery, which can be fully charged just within 2 hours courtesy of its quick charge function. The battery size has just what it takes to carry you throughout the day and when out of power, all you need is a micro USB connection to get back your charge.

The TFV8 tank includes 2-3ml e-juice capacity (depending on the model you choose) that can be refilled from the top while the air-flow control puts you in charge of the vapor production.

We can undoubtedly confirm that SMOK’s new and small mod is a great one, considering its portability without scarifying any of the device’s power. You get to enjoy an output of up to 50W due to the Q-Box mod being correctly paired with the TFV8 Baby Tank. This power is high enough to create huge vapor clouds and as many suggest, the best flavor clouds too. You are not limited by the Q-Box as it is compatible with most tanks on the market so if you prefer your own tank over the TFV8 Baby tank, no problem, just switch them out!

The mod supports a resistance of as low as 0.06 ohm, temperature control and includes switchable volts and wattage modes. The 0.96 inch LED screen is clear and bright enough for you to get all the information concerning your vaping activity and has a number of functions for the purpose of protecting you and your mod.

Smok Q BOX

The Design

Apart from quality, SMOK is also known for the creativity they cast behind their products. In fact, SMOK mods vividly support this claim, as their design is the epicenter of attraction. That seems untrue when it comes to the Q-Box as innovation appears not to have been taken as a serious matter. But we can give it a plus as its design beats most other devices found in this category of small vapes.

You may worry about the output of just 50W, but let’s be realistic for a second. The vast majority of vapers who use the pre-installed coils will only vape at a range of between 20-40W, mostly in the 20W range, so the 50W output is more than enough and the 1600mAh battery will last longer the lower the output power is. The thought pattern with this design is to produce a mod that will fit with the majority of vapers needs, especially those who want a mod to stick in their pocket while out and about.

The impressive 1-inch screen fits perfectly with the small size and provides just at a glance data on battery life, temperature, wattage, resistance as well as the remaining puffs – calculated on your average user behavior.

It comes in a variety of colors including purple, silver, gold, black and the multi-color option which has come accustomed to as a norm by SMOK. Then there is the steel tank that beautifully fits in with the Q-Box design and colors, resulting in a device that is not only good-looking but also one whose functionality and efficiency is unquestionable.


Do you ever worry that you may be harmed in the process of vaping? Well, worry no more with the QBOX TC because it has safety features for your benefit. The kit makes no exception when it comes to reliability and safety, and protects you from short circuiting, overheating. If you are abruptly held up and forget to turn off the device, everything will be done for you since it has a 12 second cut off time.

Gone are the days when you unexpectedly run out of power because there is a low battery warning light to act as a reminder. There is the puff monitoring system that keeps track of average usage and advises you when it’s time to do an e-liquid refill. Overall this mod is competing well for the title of best e cig, but many experienced vapers just cannot look past the small battery capacity, but this is the sacrifice you have to make if size is the most important factor.

Smok Q Box

Specs in brief:

  • The following are the SMOK QBOX TC Kit specifications:
  • 8*33.57*25mm
  • 119 grams
  • 1-50 watts output range
  • Less than 500uA standby current
  • 1-9.0 volts working voltage
  • 200-600F/100-315 C temperature control
  • 1600mAh battery size
  • 96 inch OLED screen
  • Zinc alloy building materials

There are good things and bad things to say about the QBox, the major ones include the small 1600mAh battery, if your vaping at 50W and vape a lot, this isn’t going to be for you as it will struggle to see out the day! Granted, it’s not the perfect device, especially if your looking for an electronic cigarette to quit smoking with. If however, you are like the majority of vapers vaping at around 25-30W then this box mod is perfect as a device to carry around with you and this is exactly the intention of SMOK’s design. Utilizing the successful TFV8 Baby Tank, this kit is hard not to like!

If you are vapers vaping at around 25-30w,  Smok Q box mod is the perfect device to carry around!

Review of Limitless Pulse Pod

Limitless Pulse Pod

The Limitless Pulse Pod System, by Limitless Mod Co and Ply Rock, is a new, draw-activated, closed system pod mod with a difference – its pods are refillable.This is a pod-based system which offers the user total control in what e-liquid they vape. The Pulse starter kit ships with the mod itself and two unfilled pods, retailing for $29.95, and a pack of three refillable pods sells for $11.49. The Pulse’s battery comes out at roughly 380 mAh, with a fixed 8 W output. The pods are 1 mL in capacity (although specs elsewhere state 1.5 – 2 mL). The inbuilt coils put out between 1.7 – 1.8 ohms and use silica as wicking material. The Pulse has a striking, futuristic look – LED accents running along the device light up on inhalation. The triangular button up front turns the device on and off, and toggles between the 7 color choices (and stealth mode). Don’t judge a book only by its cover, however. Let’s take a closer look and vape on the Pulse and find out how it performs.

Limitless Pulse Pod

For a pod mod, the Pulse comes in lavish packaging. First impressions are great and the device looks futuristic with its dynamic accenting. The pods seem robust and the plastic mouthpiece pops off easily with a bit of prying. The Pulse is draw-activated, but can be turned on and off with five clicks of the button that also controls the LED accents.

One of the first things I notice is the beveled edge of the base of the device. This is one pod mod that is not intended to stand upright, and the sharp angle of this edge serves no purpose except to light up and look cool.

The pods

Limitless Pulse Pod

The pods click into the Pulse device easily enough, although the angular profile of the top of the Pulse makes it less plug-and-play and more push-and-jiggle than I’d like. I’ve seen conflicting specs for the Pulse from different sources so filled up one pod with a syringe of e-liquid. To my surprise, the pod only has a capacity of 1 mL. This is the smallest capacity of any pod mod system I’ve seen.

The coil and wick are located at the base of the pod. The coils use silica as the wicking material. By prying the positive and negative pins (still attached to the coil) out of the pod housing, I was able to get an ohm reading on a metering tab. It came out around 1.7 – 1.8 ohm. According to Limitless Mod Co’s blog, the pods can be refilled 8 to 12 times before they need to be replaced.

Refilling and hacking

Limitless Pulse Pod

Refilling the pods is simple. Remove the black mouthpiece with a little pressure and you will see a red rubber plug. This covers two holes on either side of the airflow chimney. A red arrow on the pod body indicates that only one hole should be used for refilling (to allow air to escape out of the other).

You will need a unicorn bottle or syringe to refill. I measured a capacity of 1 mL based on the syringe I used. Even for a pod mod, that’s small. But with an output of 8 W, you aren’t going to be burning through the e-liquid anyway.

The base containing the coil and wick can be easily pried away from the pod housing using a pair of elbow tweezers. I counted 9 wraps on the coil with an inner diameter of 1.5 mm. If you need to dry burn the coil, one option is to unfold and remove the gold connection pins (with the coil still attached) from the pod housing. Connect the pins to the positive and negative posts of an RDA and screw this onto a metering tab.

How it performs

Limitless Pulse Pod

The LED accents will certainly turn heads. You can also turn them off by clicking the triangular button 3 times to go into stealth mode. One issue I have is that they don’t indicate battery life. When your battery’s done, there’s no warning – the device simply blinks three times, and then it’s out. However, the device went from empty to fully charged in about 40 minutes.

The draw on the Pulse is restrictive, similar to a Nautilus or Nautilus X tank at their most closed-off. Among pod mods, I would compare the draw to the Juul or Juno, but more closed.

How is flavor on the Pulse? When the battery is fully charged it’s OK , but it deteriorates as the charge decreases.

The biggest change is with vapor production. On a full charge the Pulse produces a decent amount of vapor, for a pod mod. With a decreasing charge vapor also decreases. This feels strange, considering how hard you have to inhale on it.

I love the idea of a refillable pod mod system. For that to work, the components have to be built for multiple re-use. On one pod, the mouthpiece cracked after being removed a couple of times. The pods themselves are somewhat leaky. I have had issues with spitback, and getting e-liquid flooding through the mouthpiece.

The Pulse Pod System is a step in the right direction but needs more work to make a decent refillable closed system. Personally, I find the draw too restrictive. The flavor produced isn’t anything to write home about. Pod capacity is somewhat on the small side. Perhaps it’s the combination of silica wicking, low output wattage, and an overly restrictive draw that make for an unsatisfactory vape on the Pulse, for me at least.

On the plus side, the pods are hackable, and can be dry burnt. The price seems fair for a pod mod with two refillables included.

All in all, I really  love the concept of Limitless Pulse Pod– a refillable pod mod system and the price is also affordable.

Review of Smoant Battlestar 200W

Smoant Battlestar 200w

Intro:  Smoant Battlestar 200W is an innovative box mod, coming in eight different color schemes!

I’ve once analyzed that due to the lack of new technology support, 2016 will witness the race of appearance and function in the e-cig market, on which condition multi-function, easy operation and beautiful appearance will become the new standard for the consumers to select devices. In the aspect of appearance, there are mainly two developing directions: one is the feeling of science and technology, another is Retro Style.

Smoant, the sub-brand of Cloupor, has launched a new e-cig product called Battlestar previously, which has strong sci-fi color about it from the appearance to the name.

This dual-18640 200W box has become a focus of attention because of not only its eye-catching appearance, but also its 200W maximum power—could a dual-18650 device really produce the power as high as 200W? What is the output effect of Battlestar? What about its craftsmanship? As I recently has received its sample for test, here I would like to reveal the answers to the above questions for you.

Smoant Battlestar 200w

Battlestar 200W adopts paper packaging, whose color scheme is good. The main features of Battlestar is explicitly marked on the paper box: small, compact and ergonomic.

On the yellow back face there are more detailed information about the mod.

Smoant Battlestar 200w
Smoant Battlestar 200w

Inside the box there is a Battlestar 200W mod, a bilingual card, a handbook and an accessory box that contains a USB cable and a box of standby magnets.

Smoant Battlestar 200w

There are totally eight alternative colors, and the sample I received is in yellow and black

Battlestar, similar to WISMEC RX200, adopts the triangle design that could make the best use of space to reduce the size of the mod. Its appearance is very consistent with its name Battlestar, of which the yellow body and black buttons look conspicuous.

The surface of the mod uses anti-proof and wear-resistant rubber paint, ensuring good grip feeling. But some corners’ painting face remains to improve. Nevertheless, the overall stability of the mod is good.

Smoant Battlestar 200w

Battlestar 200W adopts the spring 510 connector, which takes up more than half area of the mod’s top. The three grooves around the 510 connector are not appropriate, because they may lead the e-juice leaked from the atomizer into the connector.

The operation area of the mod is regular, where the fire button is above the screen and the adjusting buttons are integrated into one single button.

The sides of the body have some simple ornamental moldings, and the black battery jar cover also makes the mod less monotonous. To facilitate the heat dissipation of the chip and batteries, there are several venting holes for them.

On the bottom of the mod there are also four venting holes for the chip.

The protective pasting on the screen could effectively protect it from scraping.

Smoant Battlestar 200w

The battery jar is fixed to the body through eight magnets. It adopts the snap joint design, thus the connection is compact and firm. The craftsmanship and material of the battery jar are also quality. The two batteries are in series, and the positive poles use spring contact.

Maybe it was for the overall effect of the mod, there is no gaps around the battery jar cover for the convenience of opening. For that reason, it may be a little bit difficult to open the cover using our finger nails like usual.

Smoant Battlestar 200w

The right approach is to hold the mod using one hand, and put another hand’s thumb, index finger and middle finger on the venting holes of the cover, then pull outward hard to open the cover. It really need great strength.

Smoant Battlestar 200w

Battlestar 200’s screen display is comprehensive, which consists of the electric quantity, the modes, the power, the resistance, the real-time output voltage and the temperature if under the TC mode.

Smoant Battlestar 200w

Battlestar 200’s operation is very easy. Just press the power button three times in succession to call up the function menu, and press the adjusting button to shift and press the power button to confirm.

Besides the normal VW output, Battlestar also supports the TC modes for Ni200, Ti, SS and NiCr and provides three TCR presets for the users to self-define the TC material.

Smoant Battlestar 200w

Many vapers doubt that whether two 18650 batteries could really produce the power as high as 200W, though SMOK’s dual-battery H-PRIV 220W has previously been proved to have the same performance as DNA200 under the power of 200W.

To address this issue, I’ve made a professional comparison test. I compared the vapor effect of Battlestar 200W and DR200 by using the same atomizer and batteries and ensuring the 100% charge status during the test.

Through the picture we could see that Battlestar is inferior to DR200 in vapor volume. Moreover, under 200W, Battlestar has nearly 0.5 second’s latency after firing.

In fact, many VW mods have this kind of latency. I think that it’s because most VM mods’ menu and settings are also called up by the power button, therefore it has to leave some time for the chip to react accurately to your command.

Since the invention of e-cig, the functions and performances of the devices have all changed a lot, but the operation of most devices still continues the initial method—press the power button five times in succession to power on or lock the device, and press three times in succession to enter into the setting menu.

Though some mods specially added the function button to simplify the operation, they have not forms the mainstream.

In fact the increasing of a function button is much humanized. It could reduce many tedious steps, save the latency time of the chip and accelerate the device’s reaction time. Though there is possibility of mistakenly touch, but it do more good than harm.

Smoant Battlestar 200w

Actual Experience: 

  1. Appearance

Battlestar 200W’s triangle structure reduces the mod’s size. Its dimension of 8.4cm*3cm*4cm is competitive even among single-battery mods. The mod grips comfortable no matter in what way.

After being installed with two batteries and an atomizer, Battlestar 200W’s weight is still moderate, and it is small and convenient to carry.

Smoant Battlestar 200w
  1. Performance

As for the output, each person has his own requirements and judgment standard. I don’t have professional test instruments to test the authenticity of its claimed 200W output, but you guys could refer to vapor comparison between it and DNA200 above.

In the aspect of temp control, I’ve used several sub ohm atomizers to experience the NI, TI and SS modes, and I found that the coils’ heat-up speed is fast, the output is continuous and there is no apparent impulse. The effect is similar to dual-battery mods.


Battlestar’s resistance detecting is accurate, and the data is very close to that of the detecting software.

Smoant Battlestar 200w
  1. Ease of Use

Battlestar 200W operation is easy:

Press the power button five times in succession to power on/off; press the power button three times to enter the setting menu; press the adjusting button to shift; and press the fire button to confirm. After the atomizer is installed, the confirm menu will pop up automatically—press “+” to set new resistance and press “-” to set the original resistance.

Long press the two sides of the adjusting button simultaneously to change the screen orientation; long press the fire button and “+” to change into the “black character and black background” mode for the purpose of looking clearly the screen under hard light.

Long press all the buttons to lock the power and temperature setting to avoid mistakenly pressing that may change the parameters.

Under the TC mode, long press the power mode and “+” to set the maximum output power.

But the mod don’t have the function of locking the device, therefore we have to power off to avoid the mistakenly touching while putting it into the bag.

Generally speaking, Battlestar’s operation is simple enough even for newbies.

Smoant Battlestar 200w

As a small size dual-18650 200W mod that has special appearance and good color scheme, Battlestar 200W is a cost-effective product among like mods.

  1. Disadvantages
  2. The corners’ painting face may easily peel off if scraped with hard matter, therefore try not to place the mod with hard things like keys, mobile phones and coins. But the overall painting of the mod is firm.
  3. The grooves around the 510 connector may lead the leaking e-juice inward, thus frequent cleaning is needed. The 510 positive pole is a little too high, thus it may produce gaps between the mod and the atomizers whose bottom electrodes is projecting.
  4. The battery jar cover is difficult to open due to the lack of slot design.

In Summary, Smoant Battlestar 200w box mod is especially unique in appearance and the performance is also satisfying!Worth trying!

This is one of the most important items in the kit.

Not only does it make a great stand for building – more importantly you can check the resistance of your coil – dry fire it – and fine tune it until you’re happy.

It has a resistance range of 0.1 to 9.9ohm and spring loaded 510 threaded pin – I had no issues using a variety of RDAs and RTAs.

Coil Art MAGE RTA Review


Recently, Coil Art has launched a mini RTA—Mage RTA, which goes the route of small size RTAs. I’m here to share my use experience with you guys.

Mage adopts paper box packaging, of which the top is transparent and imprinted with the logo of Coil Art. Through the transparent part we could see the atomizer inside. The two sides of the box are imprinted with the pattern of wand and the product name respectively. The front side is marked with the diameter and tank capacity.

Inside the pack there is also a standby glass tank, a hexagon wrench, several colorful sealing rings, a pack of standby screws, a card and a Coil Art silica ring.

Mage’s structure is the same as the typical bottom airflow liquid storage atomizers. It has three bar shape adjustable airflow ports. The material and diameter of the drip tip indicate that Mage is a big vapor atomizer. The large diameter is beneficial to discharge vapor, and the nonmetal material could prevent from conducting heat to the drip tip and burning the mouth. On the bottom of the evaporating tank there are four liquid flow holes. The logo of Coil Art is engraved on the center of the inner tank.

After completely dissembling the atomizer, we can see that the quantity of hardware is relatively small. The only five parts are: an integrated drip top, a tank cover, a glass tank, an evaporating inner tank and a base.

Judging from the hardware, Mage is a highly integrated atomizer. Each of the hardware has dual functions. For example, the drip tip has the function of sealing the liquid tank at the same time and could be connected to the 510 tip. The tank cover is integrated with the vapor tube and the cover of the inner tank, which has reduced the amount of hardware and is convenient for operating and maintaining. The design of the tank’s top cover indicates that Mage is a top filling RTA. The drip tip is connected to the top of the vapor tube through the thread, and it could seal the liquid tank via the sealing ring.

The base of the RTA also adopts the common structure of U shape four-hole electrode, being convenient for installing coils. The size of the holes is suitable for passing trick coils. The large size airflow ports are on the bottom—below the coils—and the position is higher than the bottom line, for the purpose of preventing liquid infiltration.

The positive power supply electrode is relatively thin, thus could be compatible with some special devices, for example, the boxes and mods whose 510 positive electrodes are excessively thick or thin, preventing from short circuit caused by the close distance of the positive and negative electrodes. Besides that, the atomizer should be installed by rotating the electrode deck (the 510 negative electrode in the picture was carelessly broken by me), thus regular thread and pin-lift structure can hardly realize and the stability could not be ensured.

Seen from the side, the center of the lower two coil holes are paralleled with the airflow ports. The excessively close distance of the coil and the port makes the two could easily touch each other and thus results in short circuit. Therefore, when installing the coils, try to raise the height of the coils to avoid touching with the ports, and ensure that the length of the coils is longer than the diameter of the ports.

As officially recommended, I’ve made the 2.5mm loose coils and raised them as high as possible, and the actual effect is not bad. Although the tails of the coils are close to the ports, they are not connected.

Mage could have raised the height of the ports by several millimeters to avoid this trouble, after all safety and practicability are more important than appearance and size.

The relatively large diameter of the coil holes is prepared to be matched with trick coils. I’ve tried to wind the 24Awg 2.5 coil for seven circles, however, because the length of the coil is shorter than that of the ports, their distance is too close. And if the fixing screw is too tight, the coil will be pinched off. So I will advise you guys to use trick coils or thicker ones like 22Awg coils to match with Mage.

The installment of Mage’s inner tank and the process mode of the cottons are similar to those of Five Pawns and KF4. Pass the cotton through the coils and leave moderate length, then put in the two sides in succession and screw the inner tank, after that press the cotton inside the bottom, being close to two sides of the ports and corresponding to the position of the liquid flow holes. The tails of the cotton shouldn’t be left too long, otherwise it will obstruct the process of liquid flow.

Mage’s inner tank is connected to the base through the outside thread. Pay attention that there are snap joints in the bottom, we should aim at the right position while installing, and then screw the inner tank to fix it on the deck.

The cover of the oil tank is integrated with the vapor tube and the inner tank’s cover. After the coil head is finished, put the glass tank on and point the inner tank’s cover toward the tread, press it down and screw to finish installment.

The overall size of the tanks’ covers have been reduced to the smallest level, so much so that after the sealing ring is installed, users should push down the cover heavily to put it into the tank.

Upon finishing the installment of the tanks and checking the position of the sealing ring, you could begin filling the liquid through the port on the top after closing the airflow ports on the bottom. The tank capacity of Mage is around 3.5ml, equaling to four droppers of 30ml liquid. Its cruise ability is well enough considering its small size. The liquid consumption is equivalent with RDAs with the same parameters.

Actual Experience:

  1. Vapor Volume

Mage has the same base structure as RDAs, thus its vapor volume is also relatively large, being almost as well as RDAs under the same data. However, RTAs are equipped with liquid tank, thus the adding of evaporation tank and vapor tube has affected the vapor volume to a certain degree and make it a little bit smaller than RDAs under the same data.

  1. Flavor

Mage’s evaporation tank endows it with excellent flavor performance, making the flavor richer than regular RDAs.

  1. Ease of use

The biggest advantage of the four-hole dual electrodes structure is its convenience for use. But the excessively close distance between the bottom airflow ports and the coil holes could easily lead to short circuit, therefore it brings trouble in building and installing coils. That’s the reason why I don’t recommend it to beginners.

  1. Craftsmanship

The craftsmanship of the atomizer in my hand is relatively exquisite. But some details need to be improved, for example, the uneven surface of the electrodes, the position of the coil holes and some rags in the corners.

In summary, Coilart Mage RTA tank can produce big vapor as well as deliver rich flavor.
