Lately, things have been a little bit quieter than usual in the Kanger camp which led me to believe that something new and potentially exciting was in the offing.

And not to disappoint us they have come up with not just one, but two new products based on the original K box design and Subtank Mini that has increased style and incredible performance, with a re-designed coil thrown in for good measure. Impressive!

Their new 50W Subox complete starter kit includes something for everyone whatever level of vaper you are. From the Sub Ohm builders to the novice vaper, the Subox Mini kit is going to impress you with its latest innovations and in a finish that is as classy as it is original.

Kanger rarely disappoint the vaping community with their product line and with the introduction of the Subox Mini kit they are most certainly going to raise some eyebrows!

Function & Performance

I have used the ranges supplied in this chart for overall consistency, including the Subox Mini’s full range from  7W watts up to its maximum of 50 watts, using two different E-Liquid combinations from Five Fold Vapor and Dark Market. For customers within the UK, these E-Liquid lines can now be purchased online.


REACH compliant

If you intend to use this range of E-Liquids, please make sure they meet the current requirements set out by your countries regulatory bodies.
For EU countries, more information on this can be found here along with REACH’s partner agencies from around the globe.

E-Liquids may contain diacetyl (DA) and acetyl propionyl (AP) or other carcinogenic ingredients or disease-causing substances, so please be aware of this and seek medical advice before using any of the products used in my reviews.

People can suffer from allergies to chemicals that may be present in the makeup of certain types of E-liquids or produced in their vapour. People can become sensitive to, or even allergic to Nickel or Titanium used in Temperature Controlled designed coils. Again, please be aware of this and seek medical advice before using any of the products used in my reviews. Also, check with your E-liquid supplier or the equipment manufacturers directly before purchase and use.

You might find this range of calculators provided by Steam Engine particularly useful, so thank you to Lars for allowing me to include them in my reviews. These calculators are currently under development, and the information that they contain may change at any time without notice. Please read the How It Works section for a more in-depth understanding. And never leave your device charging unattended, make sure you are using the recommended battery for your device, and always remember, SAFETY FIRST.

Potential Polycarbonate problems

It is well known that certain e-liquid ingredients can cause cracking or even melting of polycarbonate plastic or acrylic tanks and tubes. For further information on this subject, please check with your E-juice supplier or contact the manufacturer directly.

Let’s take a look then at the Subtank Mini first followed by the Subox 50W.

The latest version of the Subtank Mini has been designed first and foremost to be used in conjunction with the 50W Subox Mini.

Featuring dual airflow inlets and a new vertical coil design, it would appear that Kanger has tried hard to improve on their previous versions. To help with heat dissipation a ceramic coating has been applied and a Delrin drip tip included, which should contribute to providing a more comfortable vaping experience overall, especially at the higher wattage settings.

A redesigned vertical Sub Ohm coil replaces the previous horizontal models retaining the Japanese Organic Cotton helping to improve both vapour production as well as flavour.

They have also enlarged the size of the two juice inlets on either side of the coil and made suggestions for temperature ranges based on the VG content of the E-Liquids being used with them, helping to provide the new user with a far more pleasant first time Sub Ohm Vaping experience. (See under)

Temperature Recommendations

0.5 Japanese Organic Cotton Coil:

80-100% VG: Between15W-40W

50-70% VG:   Between15W-45W

20-40% VG:   Between15W-50W


Previously the Subtank Mini came with a spare Pyrex Glass tank, and additional O-Rings included however with the new model you will not find these included. Opting for the white version of the Subtank, however, will include another White drip tip replacement.

Further Improvements have also been added to the RBA section that allows for better wicking Of the E-liquid by including two larger holes in the sides of the main housing replacing the two smaller ones that were initially placed at the bottom on the original version.

Kanger has also made access to the new RBA section far easier by using a Philips screw in place of the previous threading, so no more nightmare scenarios with this part in future when you’re trying to remove the outer casing to create a new build!

They have also included peak insulation for thermal protection as well.

Kanger SUBOX

8685c26c3bd2911a56fcc6aac702a42f - CopyIncluding a new livery to match the colours of the Subtank Mini, the new Subox is a 50W device that can fire down as low as 0.3 Ω and up to a maximum of 50W adjustable in 0.1 increments.

This is a very sleek and stylish design that is simple and very straightforward to operate. It’s perfect for the novice users to get to grips with and truly a joy to use for the more experienced vapers as well.

Remove the magnetic battery housing and place the recommended 18650 battery for Sub Ohm vaping inside making sure it is put in the right way round!

To turn the device, ON/OFF just press the fire button five times in quick succession to power up the Subox and select your desired wattage using the recommended settings for the type of E-Liquid that you happen to be using which as I have previously mentioned can be found on the coil itself.

At this point I would strongly tend to suggest that you do not attempt to build your own coils until you have a clear understanding of Ohm’s law and battery safety first, so stick with the pre-built ones instead.

You might find this choice of vaping calculators provided by Steam Engine particularly useful, so thank you to Lars for allowing me to include them in my current and future reviews. And be sure to read his disclaimer entirely in the about section on his website before use.

Use the +/- buttons to increase or decrease the wattage in increments of 0.1 to achieve your preferred setting. The +/- buttons held down together will also allow you to change the orientation of the OLED screen to your preferred viewing angle.

All of the operational information that you require to operate the Subox Mini can be found on the bright and easily readable OLED Screen, from the current battery charge status, voltage, and wattage settings, to the current resistance value of the attached tank.

Kanger has also included a mini-USB charging port with this model allowing you to vape while charging which can be seen below the  +/- buttons.

And finally, you will notice that battery stickers have been provided to help match up their colour to the Subox as they are visible through the venting hole.

This is a fantastic package that will be enjoyed by novice users to the more experienced amongst us. If this was their intention when they designed it, then I would say, without a doubt, they have managed to achieve it making this a really fantastic package.

The Subox Mini includes a flush 510 Fixed Connector with four air channels. It would have been an added bonus to have made this a spring loaded connector instead. Update: Kanger has informed me that a Springloaded 510 Connector will now be included in future releases!

Changes to the airflow system along with the inclusion of a vertical coil setup have seen a better increase in vapour production, with the flavour remaining on par with the previous Subtank range. It is also noticeably quieter to use with spit back now becoming a thing of the past, so a tremendous improvement in this department as well.

The increased diameter of the juice inlets with the RBA section, however, is where I noticed the biggest change, creating better wicking of the thicker E-Liquids and in turn increased flavour and vapour production overall, along with reducing the likelihood of burnt hits.

The inclusion of two O-rings instead of one on the base of the RBA would make a very secure fit and therefore not require the addition of the Phillips screw. This works very well on a tank I recently reviewed so I cannot see why it shouldn’t work here as well.

As I have mentioned previously in other similar reviews, the airflow control ring would be better placed above the E-Liquid container if we are going to eradicate any further possible areas where the issue of leakage can occur.

Also, a heat buildup in the mouthpiece is an area that needs to be addressed in more detail as well due to the increasing temperatures that people are vaping at these days, and we have recently seen some useful and novel ways to achieve this from other manufacturers.

The Delrin drip tip on this model helps in reducing the heat build-up, but I’m hopeful that the KangerTech engineers will be able to improve upon this further and create something special with their next release to address some of the points I have raised should they choose to do so.

Both colour options sent to me for review look kind of cool (Black & White versions), so the Bling factor appears to be covered in these designs as well! A version in Orange and Dark Blue might also be a worthwhile consideration?

The Aqueous ceramic coated matte finish not only looks good but feels extremely comfortable to hold, and due to its small size minimizes the risk of it slipping from your hand.

The magnetic battery compartment is the best-designed version of this I’ve personally used so far, making it very quick and easy to gain access to replace them.

Producing a maximum output of 50 watts is about the limit with a device of this size as battery drain happens reasonably quickly above 25 watts, so make sure you have spares on hand and follow the manufactures recommendations on battery choice to the letter as always.

And don’t forget the Subox now has a vape while charging capability included making it a far more versatile device if you happen to be near a mains socket!

The OLED screen is easy to read even in sunny conditions giving you all the information you require at a glance. And the positioning of the three buttons makes it easy to change any of the functions on the display along with firing the device itself helping to create a comfortable user interface.

With the combination of price and functionality, along with its simple but stunning looks, the Subox kit is going to become extremely popular, and was most definitely worth waiting for.

Expected price range appears to be around the £55.00 or $70.00 mark.

  1. Gregg, to be honest when I wrote the guide, I had in the back of my mind the snratge feeling I was missing something. At the time, I didn’t realize the flavor’ wick was what was falling out of the atomizer. I should update the article to say put that back! I’ve actually received a comment on a follow up article by someone who replaces that wick with a bit of rolled up cotton, to be larger and longer than the old flavor’ wick and it made all the difference in stopping the gurgling and flooding of the atomizer

  2. Thanks for writing this article. I’ve been vaping about a year now. Originally it was to quit smoking. Then it was finding something like a better vaper. I started on the original V2 junk and every month or two seemed to upgrade to something a little better. On the way I eventually got into the Ego One. I really liked it but it quickly became not enough.

    I recently got this Subox Kanger and I am still learning about it. I was afraid to burn the coils so I wasn’t completely satisfied until you provided the information that I needed. I cranked up the wattage to 35 and now instead of trying to lung hit this thing for 18 days to get a decent vape it was only a second or two and I was huffing down the tracks!

    You might want to mention people get an extra battery with this thing. They don’t last very long when you are producing nuclear mushroom clouds.

    All in all I hope this will last me for a while. The only cons. My vape shop raped me on the price and they didn’t tell me I could have gotten into a better setup for a few dollars more. At least I know my next device will be purchased at the best price on the net. I may even start going to the net to get my juices.

  3. Hi there, has Kanger released any information on the improved 510 connection? Thanks

  4. I wish it had a way of locking the buttons

  5. Hi my subtank spits e liquid in my mouth…what should i do?

  6. Have you experienced an issue with the power button getting stuck in the “depressed” position??

    • I noticed this too. Maybe normal?

    • yes and its an easy fix, they use to much paint and the paint buildup around the fire button hole is too tight, just take the 2 screws out in the battery area pull out the internals, being carefull not to loose the top spring and cap, then take a knife or scissors and put in the fire button hole scrapping a little paint off , go from outside in the inside out doesnt take much, then put everything back together and problem fixed

  7. I have been trying to find lower olm coils for the kbox mini. .03 or lower ???

  8. The Mod itself is good, the battery lasts a decent amount of time and the ability to change the watt output is impressive, for such a small device. Although, the Sub tank itself is very much opposite. Within a week the coil is in need of a change, due to burning the liquid, and will leave the sub tank leaking even the liquid being used is of a high VG. After having it for 2 months I have changed the tank and haven’t had any problems. After speaking with friends and looking on forums this is a common problem and I won’t be purchasing from Kangertech again.

  9. Mine leaks any idea why???

  10. The newest coils for this tank are awful. The inner part of the coil that’s supposed to go over the chimney is too small and makes the gaskets go wonky. If you take it apart to refill, then the seal isn’t right and the tank leaks everywhere, through the air holes and the mouthpiece. The coils burn randomly and taste like chemicals, like when you light the wrong end of a cigarette.

    The battery takes ages to charge in the mod, plugged into the wall. I had one bar left and it’s been charging for 6.5 hours already and still haven’t finished.

    I put my aspire nautilus on instead because even tho I go thru coils every 3 days… at least it doesn’t leak or taste like crap.

    • I didn’t have any problems with the OCC coils, however, I recommend just making your own with the RDA kit included with the tank. It saves a ton of money compared to buying coils and tastes amazing using Japanese organic cotton. I rewick every 2 or 3 days and a coil should last weeks if not longer. Just burn off the black stuff after taking out the old wick then rewick.

  11. Not getting no power how do I change the setting from watts to heat because mine is stuck on the heat setting?

  12. My kangertech subox mini starter kit havig a problem. I. Charge my subox and its good i use it nonorally in 30watts. When i change the battery. No power comes up, so i try to charge it my backup battery but suddendly its still he same no power comes in te LCD. I try back the previous battery in good mood. No power gain . i searc any related problem but i cant see.
    Anyone know how to fix this problem? I am newbie on this vape

  13. whats the best coils to use in my kangertech subox mini 0.5 1.5

  14. I have just started using this device and so far so good. I have just changed to a 100% VG and i am on 30 W, is this ok as it tastes fine.

  15. Why cant i change the voltage on my kbox nano
