Kimsun TC40W Mini Kit Review

If you’re in the market for a stealthy box mod that has a decent power output, does temperature control and is firmware upgradable, look no further than the tiny Kimsun TC40W Mini. In this review, we’ll be taking a look at the kit version of this device, which comes with the Kimsun STL Tank 2.

I’m going to be perfectly honest and say that I wasn’t expecting very much from the Kimsun TC40W Mini mod. The brand name didn’t ring a bell – I later learned it’s a subsidiary of Chinese manufacturer Kimree – and after seeing how small this thing really is, I was convinced it was going to be a total letdown. Boy, was I wrong! The TC40W Mini is actually very impressive for its size, with a maximum power output of 40 Watts and several built-in features that I’m used to seeing in larger, more robust advanced bods.


A Look at the Contents

The Kimsun TC40W Mini kit includes the box mod, a 1.1 ml glass tank, two Titanium coil heads (0.32Ω), a charging/upgrade cable, a user manual and a bunch of promotional materials (leaflets, cards, etc.). Basically, apart from e-juice, you have everything you need to start vaping.

The size of the TC40W Mini will probably shock you. Until seeing this device, I was convinced stealthy box mods couldn’t get any smaller than the Eleaf iStick Pico, but the Kimsun actually makes that thing look big and bulky. At just 34.6(L)×21.2(W)×99.3(H)mm in size, the TC40W Mini is definitely the tiniest box mod I have ever used. Just so you get an idea, it’s smaller than a 30ml juice bottle. It’s also incredibly light, making it easy and comfortable to carry around in your pocket.


The TC40W Mini has a classic rectangular design, and a matte black finish with the Kimsun logo on one side and the name of the mod on the other. The spring-loaded 510 connection is located on top, the mini-USB charging/upgrade port is on the bottom, and the power and adjustment buttons are on one of the smaller sides of the mod. The only thing I couldn’t figure out was where they had put the LED display.

I knew that the Kimsun TC40 Mini was supposed to be a variable wattage and temperature control mod, but with no display to be seen, how was I going to tell if I set it up correctly? I actually had to consult the user manual about this, and found that the metallic top side of the device is actually a concealed LED screen that is only visible when you push one of the buttons. It’s a clever way to incorporate the display and only adds to its stealth-vaping qualities.


The display is one of the brightest, most elegant I’ve ever seen on a mod. The info is displayed in large purple characters, making it easy to read. Pressing the power button on the Kimsun TC40W Mini brings up the LED screen. The battery life is displayed for just a second, after which it quickly switches to the current wattage setting. You can adjust the power output by pressing the “+” and “-” keys, or go into temperature control mode. Just press the power button three times in rapid succession to get into the menu and browse the available options. We have “PPP” or power mode, Ti (both Fahrenheit and Celsius) and Ni (also Fahrenheit and Celsius). Unfortunately, the TC40W Mini doesn’t support stainless steel at this time, but that might become available through a firmware upgrade, at some point.

The mod reads the resistance of the atomizer automatically after you screw it on, and you can see it on the display by pressing the “+” and “-” buttons simultaneously. To turn it on and off, just press the power button five times in rapid succession.


Battery Life and Overall Performance

It’s important to keep in mind the size of the TC40W Mini when talking about battery life. The 1100mAh capacity of its built-in battery may not seem like much when compared to that of high-power dual-18650 mods, but for what is essentially a micro mod, it’s actually pretty decent.

Using it at the full 40W, I could only get about two hours of vaping out of the Kimsun TC40 Mini before the battery needed a recharge, but I noticed that lowering the wattage to about 25W increased battery life to about half a day. As a heavy vaper, this is definitely not a device I see myself using exclusively. I usually vape at much more than 40W and the battery capacity just can’t keep up with my daily needs.


But that’s what my bulky, high-power box mods are for. The TC40W is perfect for vaping on the go, which is why I usually took with me on short drives or when carrying a bigger device would have been too uncomfortable. As a backup vaporizer, this tiny thing is great! 40W max power output may not be ideal for cloudchasers and advanced users who prefer a hotter vape, but it keeps your nicotine addiction in check, and that’s what matters most.

Also, I’m pretty sure Kimsun didn’t design the TC40W Mini with advanced users in mind. Sure, it’s great for vaping on the go, but for beginners and casual vapers, it could actually be a great main device, certainly much better than the cigalikes most people start their vaping experience with. If you prefer cooler mouth-to-lung vaping, using the TC40W Mini at low wattage, could definitely increase its battery life to about a day.


Another advantage of this little guy is the passthrough option. If you’re worried about the small battery capacity of the TC40W Mini, you can just use the included micro-USB cable to keep it hooked up to a power source like a laptop or PC and ensure you never run out of power.

The user manual mentions that the Kimsun TC40W Mini takes around 2 hours to fully charge, but I noticed that that time drops to around just one hour if you don’t drain it completely. For example, I usually charge it when it still has 20% power and it goes back up to 100% in under 50 minutes.


One thing I don’t like about this device is that it doesn’t have any battery venting holes. Even though it has multiple built-in protection features, like overheating protection, short-circuit protection and low-voltage protection, I still think a few venting slots would have been required for safety purposes.

Vapor Production

When it comes to vapor production, the Kimsun TC40W Mini kit performs admirably for its size and limited power output, but I can’t help but think it could have been even better if not for the design of the STL Tank 2 coil heads. It’s actually a pity, because the tank actually features adjustable airflow slots that technically make both mouth-to-lung and direct lung hits possible, but the tiny wicking holes of the coil heads make direct hitting much less satisfying. They just don’t allow enough juice to reach the coil and also make the draw tighter than it should be


But even as just a mouth-to-lung device, the TC40W is actually surprisingly good. Vapor production is decent – by MTL standards – as is the juice flavor. You get more vapor than from any cigalike currently on the market, which I’d say makes this a worthwhile alternative for anyone looking to switch from smoking cigarettes.

If you’re looking for more than just MTL vaping, the good news is that the Kimsun TC40W Mini is compatible with any 510 tank you might prefer, although anything over 22mm in diameter overhangs a little. I for one tried it with the SMOK TFV4 Mini, and even though you could tell they were not made for each other, they performed pretty well. I’m dying to try it with the Wotofo Serpent Mini RTA, though, as they seem like a much better match. I need to get some more titanium wire first, though. The point is, this mod works with any 510 tank, so the combinations are endless.


The Tank

The Kimsun STL Tank 2 is a bottom filling tank with a juice capacity of 1.1ml. That’s not a lot at all, and even when vaping at low wattage, I had to top it off after just a few minutes, for fear of burning the coil head. It’s made of stainless steel and glass, and features adjustable airflow slots. It’s actually a decent tank, but again, I have to mention the design of the coil heads as a weakness. Because of those tiny wiking holes, chain vaping and long draws at high wattage are not recommended. The juice has a tough time reaching the coil, so even with a resistance of just 0.32Ω, you still get dry hits. To avoid them, you should probably only use the TC40W Mini in temperature control mode.



So would I recommend the Kimsun TC40W Mini kit? Definitely! Whether you’re a total beginner looking to get into vaping with a simple-to-use vaporizer that’s also elegant and packed full of features, or a casual user who doesn’t need huge power output, or even an advanced vaper interested in a tiny device that does temperature control and is easy to carry around, this little guy is definitely worth it. Did I mention that the whole kit costs under $40 ($38.80, to be exact)? You just can’t beat that price for such a stylish quality package.

Is it perfect? Of course not! The battery life isn’t  that great and the tiny wicking holes on the STL Tank2 coils are a problem, but I’d say the pros definitely outweigh the cons.

KIMSUN Air 10 Vape Mail

Vape mail is a great way to start the week, and that’s what arrived today, from our friends at Kimsun, a brand of Kimree. It’s their new AIR 10 Starter Kit. The AIR 10 features a pre-filled, disposable 10 ml atomizer.

The atomizer has a 0.25 ohm Titanium coil. It features what Kimsun calls a “U-Turn airflow input” system with three airflow ports. The Kimsun website says that there will be 15 flavors of ejuice spread across five categories; tobacco flavor, drink flavor, fruit flavor, mint flavor and dessert & food flavor.


When Kimsun contacted me they supplied a list of 10 flavors for me to choose from; Tobacco 1, Banana Milk, Honey Dew, Tobacco 2, Watermelon Smoothies, Green Mint, Milk, Strawberry with Milk, Whiskey and Chinese Style Flue-Cured Tobacco 1. I choose Strawberry with Milk, and that’s what they supplied.


The Air 10 mod has an internal 1700 mAh battery that’s rechargeable via a micro USB port on the front of the device with the included charging cable. Kimsun bills the Air 10 as a temperature control mod, though the temperature is not adjustable. It fires at a constant 530 F and, one could suppose, the ejuice is crafted to be best at that temperature.


The Kimsun website does not yet list a price on the AIR 10 Starter Kit or the replacement atomizers. As soon as I get that information I’ll pass it along, hopefully by the time the full in-depth review is live. Before that, in the next few days, I’ll post a First Look piece on the AIR 10, where I’ll go over the specs, put the kit together and give it a first vape.

If you follow Seven Report on Twitter or Facebook you’ll find out that way when those pieces are live. Thanks again to Kimsun for providing the AIR 10 for review. They’ve been a review product supplier and Seven Report advertiser for some time now.

First Look: KIMSUN Air 10

One of the newest devices from KIMSUN is designed to be simple, convenient and suitable for beginning as well as advanced vapers. It’s the Air 10. And it’s packaged with everything you need to start vaping right in the box.

There are two components to the Air 10, the mod and the disposable, pre-filled atomizer. KIMSUN also includes a micro USB charging cable and instruction manual. An internal 1700 mAh battery powers the Air 10. And KIMSUN put the micro USB port on the side of the mod, so you can stand it upright while charging.


The Air 10 is a temperature control device without the control. It operates at a constant 530° F to provide a consistent experience. There are five LED indicators on the mod that light when you’re vaping. They also serve to display remaining battery capacity. The fire button is located just above the LEDs

Made from zinc alloy, the mod is solid. The curved edge design makes it comfortable in your hand and stylish.

The Air 10 pre-filled, disposable atomizer comes with an impressive 10 ml of ejuice. It comes with a 0.25 ohm Titanium coil. There are three airflow ports on the atomizer arranged for what KIMSUN refers to as “top u-turn air inflow.”


The atomizer connects to the mod magnetically. Simply line it up with the mod and pop it into place and then start vaping. No need to prime the coil or allow it soak in the ejuice before vaping since it comes pre-filled.

The Kimsun website says that there will be 15 flavors of ejuice spread across five categories; tobacco flavor, drink flavor, fruit flavor, mint flavor and dessert & food flavor.

When Kimsun contacted me they supplied a list of 10 flavors for me to choose from; Tobacco 1, Banana Milk, Honey Dew, Tobacco 2, Watermelon Smoothies, Green Mint, Milk, Strawberry with Milk, Whiskey and Chinese Style Flue-Cured Tobacco 1. I chose Strawberry with Milk.


I attached the atomizer to the mod and gave the KIMSUN Air 10 a first vape. Vapor and flavor production were both plentiful and better than I’d hoped for. The taste was consistent, thanks to that constant 530 F temperature setting. The draw was easy and a little airy, which is how I prefer it. Overall a very impressive first vape with the KIMSUN Air 10.

Still no official word from KIMSUN on suggested retail price, but I hope to have that information prior to posting the full, in-depth review of the Air 10. That will be coming in the next few weeks, after I’ve had a chance to use the device extensively. Follow Seven Report on Twitter or Facebook to get notified as soon as that review is live.

Thanks to KIMSUN for providing the Air 10 for review. They have been a review product supplier and Seven Report advertiser for a while now.

Kimsun Slim 2 Review

Vape on Vape off with the Kimsun Slim 2 Pod Mod

The Kimsun Slim 2 is one of the first in a new wave of so called ‘Pod Mods’ to hit the vaping scene.

The ‘Mod’ part is self-explanatory – in this case it’s an 1100mAh battery with a constant temperature setting of 530 F.


The ‘Pod’ is a self-contained atomizer with 2ml of e-liquid and this can be snapped on and snapped off for easy use and disposal.

So after spending a week vaping on Kimsun’s Slim 2 is this a vaping device I’d be glad to dispose of or one that I’d keep?

Let’s take a closer look.

In the Box

As packaging goes the Slim 2 comes in a nice little box with a pull away sleeve and a clear plastic window so you can see what you’re getting before you buy.

  • X1 Slim 2 atomizer
  • X1 battery mod
  • X1 USB cable
  • X1 user manual

The device is packed with a dummy pod all ready attached which apart from the aesthetics serves no purpose whatsoever.

It’s a shame Kimsun didn’t fill this with e-liquid but hey I don’t know their margins 😉


Kimsun Slim 2 Specs

  • E-liquid Volume: 2ml
  • Atomizer Coil Resistance:0.25Ω (Titanium)
  • Temperature Setting: 530℉
  • Battery Capacity: 1100mAh
  • Charging Time: 2.5H
  • Size: 32(L)×21.2(W)×93(H)mm
  • Weight: 84.2g

Key Features

I guess simplicity and hygiene are the key features here – though saying that the one I received was anything but simple to use – more on that later.


The set-up works like this:

The pod is snapped on and off the mod and given its self-contained there’s no chance of leakage whilst vaping is as simple as hitting the fire button and inhaling. With this being a constant temperature control device the burnt coil sensation is a rare one.

I received a tobacco flavoured pod – Kimsun’s website say 15 e liquid flavours are available – and snapping it on and off was indeed a doddle.

For someone who moans a lot about leaky tanks – fiddly filling and sticky hand coil changing I have to say this aspect of the Kimsun Slim 2 is excellent.

The device can be charged standing upright and I was able to vape whilst it was charging.

Safety Features

  • Short Circuit Protection – no output when resistance drops below 0.1 Ω
  • Overtime Protection – after ten seconds of firing device cuts out
  • Low Voltage Protection – if battery dips below 3.4volts device shuts down

How Does the Kimsun Slim 2 Perform?

OK let me get this out of the way first.

The device I received didn’t seem to want to fire straight out of the box and yes even being known as a bit of a vaping dummy I did remove the dummy pod that is attached to the device when you receive it – honest!

I dutifully charged the Slim 2 for the suggested 2.5 hours and tried again – no joy. I kept it charging for a good 8 hours and still it wouldn’t charge.


Jonny contacted Kimsun who helpfully suggested I removed the ‘hygienic plug’ from the mouthpiece.

Obviously my reputation as a bit of an idiot when it comes to new vaping devices has spread as far as Kowloon. (Jonny – I’ve heard your name mentioned out in Timbuktoo)

I had of course already done that and the only other advice offered was ‘no other reviewer has had a problem.’

Must be me then I thought though the rather large word SAMPLE written in red on the box made me think not only was the attached pod a dummy but also the one in the pill box packaging.

But hey I am not one to give up – so I left it for 24 hours and a lot can happen in 24 hours just ask Jack Bauer 😉

Vaping on the Kimsun Slim 2

I kept snapping the pod on and snapping the pod off and then noticed the two connectors on the mod itself.

One was extremely springy whilst the other was sealed tight with the slightest bit of plastic blocking it.


Given I’m a techy kind of guy [not] I did what most men do when faced with an electrical issue – first off I shook it – then tapped it on my desk – then blew on it a few times – hard.

Finally I got my tiny screw driver and poked it a bit – I’m still here to tell the tale and am pleased to say the connector sprang into life and became as springy as its partner.

After adding ‘technical electrician’ to my CV I snapped on the pod and was delighted to see the red vaping light finally stayed solid which according to Kimsun means:

‘…vaping status when light in red, simulating the effect of cigarette smoke…’

Incidentally there are also four LED blue lights on the side of the device indicating the battery power remaining with all four lit meaning it’s fully charged.


I have to say my first hit on the Slim 2 was nothing to write home about however after 2 or 3 good puffs the pod came awake and I was pleasantly surprised.

The throat hit was very good for the e-liquid I tried and given this is a temperature control device with a 0.25Ohm coil the vapour production was extremely good.


However the taste of the Tobacco 1 [as they call it] e-liquid wasn’t great if I’m honest and as I had no other flavours to test I can’t comment on them ☺

I took the Slim 2 out with me for a day and liked the fact I didn’t have to worry about leakage in my pocket and indeed the weight of the thing – it is as light as can be.

I was also impressed with the battery capacity – after four days of use [a few hours here and there] it finally showed only 3 blue lights so expect plenty of use before needing to recharge.


However the Slim 2 is not the quietest of devices – given the airflow hole is as large and looks exactly like a referee’s whistle it does make a sound like an incoming mortar round.

So it’s stealthy in size but not in sound.

Also, you’re never quite sure when the pod is empty or about to empty. After 5 days or so I finally drained the 2mls [thanks TPD] and I assume the whistling gurgling sound told me it was indeed empty.

Design and Build Quality

It really is a quite beautiful thing to look at as they say on the Antiques Roadshow – but this ain’t no antique – this is suggested as the future of vaping.


Apart from my issue with the too tight connector it’s all put together nicely and the snapping on and off of the pod is strangely satisfying – ‘Vape on – Vape off!’

I like the design too and I’ve just noticed that sitting on my desk right now the Slim 2 is only slightly larger that one of my neon hi-lighter pens – it’s pretty much the same shape and weight too.

What I Like

Obviously I like the idea of the ‘Mod Pod’ – vaping on it is simple as is swapping the atomizer or pod.

The design is elegant and I do like the curved shape with a very nice rubbery base complimenting the black zinc alloy battery case – it’s certainly passes my ‘touch test’.

All in all it is a pretty nice ‘thing’ to look at and hold.

What I Don’t Like

Apart from my earlier reservations – in that mine wouldn’t fire at first – there’s not much to not like about the Slim 2 – it is what it is a vaping mod with disposable refill cartridges.

However it is rather noisy and as I’ve mentioned you’re never completely sure how much juice you have left in the tank.
