box-mod-k-box-kanger-40wThe latest fashion accessory from KangerTech surprisingly is not another masterpiece in tank design, but the long overdue entry into the box mod market that seems to be shaping up as predicted to become the style of 2015.

With a multitude of choices already available in this style, Kanger have come up with a slightly different take by including seven preset incremental wattage settings between 8 watts and 40 watts that seems to match the best performance outputs from their range of coils, making this a very simple, elegant, and straightforward device to use.

Also, the K-Box fits the current line up of 510 connectable tanks including the Nano Mini and 25mm Sub tank OCC without any overhang that should finally make a lot of people jubilant! Firing all three without any noticeable problems at all.


The K-Box arrives in a cellophane wrapped box with an outer sleeve covering. Simply push the top or the base and slide out the inner casing to access your product.

kbox_1Inside you will find one silver K-Box plus a relatively comprehensive user manual along with an authenticity card with a scan-able barcode. The K-Box uses one 18650 battery with a recommended amperage of 20A but is not included with the device itself.

The new Authenticity code found on the products lower front part of the internal boxes will apply to each new KangerTech product and include running changes for old models taking effect from late October 2014.

Further details of the New Authenticity code can be found by following the links below and on the included card:

Please be aware that this is a pre-production model sent to me by KangerTech for evaluation and review before their full production release so there may be slight changes if required to the final designs. Also please be sure to check the warranty period should it be included with the final production model of these tanks before purchasing.

What’s new

Kanger_KBox_4-500x500Kanger has come up with a pretty effective and uniquely designed lightweight 117g box mod to accompany their current range of recently released and extremely popular SubTanks firing up to a maximum of 40W and down to 0.4 ohm’s.

The main chassis of the K-Box has been constructed from aluminium, with a steel top and base helping to reduce its overall weight and making it one of the lighter box mods that I’ve personally used to date.

Flush mounting of 510 compatible tanks is almost perfect thanks to its brass spring loaded connector and the four-way counter sunk air channels creating sufficient airflow around the base of the tank used while at the same time keeping their mount as low as possible.

Opting not to include an OLED screen with their first Box mod design they have introduced a LED meter instead with seven incremental illuminated steps with predefined wattage settings from 8W, 13W, 20W, 25W, 30W, 35W and 40W’s which appears to match the optimal performance ranges of their coils.

This could be seen as a bold step by Kanger, but as we know by now they are not a company that follows the pack and always looks for something just that little bit different from the norm!

The device holds one 18650 battery that can be easily installed by unscrewing the battery cap situated at the base of the device, inserting the battery correctly and reattaching the base cap. You will notice that when you insert a fully charged battery the K-Box will be in the on position so you will not need to power On the device.

Melo_01I have used a selection of two different E-juices with varying PG/VG mixtures. These include 90% VG from Longhorn Vapor, and a new range of juices from Evo using a pre-built 0.5Ω coil setup with Japanese organic cotton in the RBA configuration, and the Sub ohm 0.5 Ω & 1.2/1.8/2.1 Ω bottom plane dual coils in its clearomizer configuration. I have also used all seven pre-designated settings, plus the new Subtank range of tanks from Kanger.

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.

The K-Box will not fire down below 0.4 ohms, so please be aware of this.

If you are new to RBA’s, useful help and direction can be found in the many forums that exist, so join and start asking questions, the people there are very friendly, and full of helpful tips & advice. You can find some of these on my website under Forums.

I have been using the K-Box now for just over two weeks continually to test the functionality and to some degree the reliability of this device and also to gauge its overall performance.

Situated on the top of the K-Box is the all brass spring loaded 510 connector pin with four air channels countersunk as I have already mentioned allowing for perfect seating of all the tanks I have tried it with so far.

The circumference allows for flush mounting of tanks up to 25mm in diameter without any overhang, so attaching the Subtank OCC gives you the perfect fit and along with a choice of setups just like its smaller sibling the 22mm SubTank Mini.

To turn the device On/Off push the power button five times. You will notice just below two vertical lines of LED meter that have seven incremental illuminated steps with the battery power level indicator situated on the left and the predefined wattage settings between 8W, 13W, 20W, 25W, 30W, 35W or 40W on the right with each setting engraved next to it.

Centred beneath this is the wattage adjustment button that round robins to your desired wattage setting and will fire atomizers from 0.4 ohms and above, so be sure to select one that matches the best performance of the attached coil you are using at the time before firing the device. I happened to notice that mine was initially set to 40w so do pay attention to this when you are using it, especially for the first time.

At the base of the device is the circular cap for removing and inserting your battery. If you run your finger along the bottom, you will see that its design allows for a relatively stable platform allowing you to leave your device standing in an upright position without the worry of it toppling over, given its fairly narrow width.

Also, the battery connection is made with what appears to be a copper/copper coated spring and so far I have not experienced any problems with either the connection of battery rattle inside the housing at all due to the springs size and firmness. Venting of the battery is situated in the laser cut Kanger Logo on the leading front edge of the device.


Using the K-Box is going to be a very pleasant experience. Encased in all durable silver body with a noticeable weight reduction due to its mostly all aluminium chassis makes the K-Box both very tactile and comfortable to hold for long periods without feeling the need to put it down.

Kanger have carefully thought through this part of the design making the K-Box  both durable and an enjoyable vaping experience for the consumer, gently rounding off the corners to remove any sharp edges that might dig into the palm of your hands, and along with its size neither too large or too small they have got their first Box mod design just about right.

Operating the device is very simple and straight forward especially for those looking to try out higher wattage settings without having to perform the necessary calculations to guarantee safe usage along with excellent vapour production and flavour when using the latest sub ohm organic cotton coils from Kanger, so for the vast majority of users they will find it a great addition to have in their collection.

Comfort is clearly a consideration, and they have gone to great lengths to get this part right in my opinion. The style of the device looks good and feels silky smooth to touch but at no time do you think that it might slip due to a rounded front section, making a snug fit into the fingers and a square back that seats nicely into the palm of your hand with no sharp and hard corners.

Seating of the tanks makes for a flush mount and clean look so when you consider the 25mm SubTank is almost the same height as the K-Box not only do you get an idea of its actual size but also how much more added length extends above the hand, and I found this combination to be very well balanced.

Exclusion for some of an OLED screen and the option to adjust your preferred settings in 0.1 increments may be a little off-putting and for some disappointing. So please don’t be put off by this as it really is a great little performer at all its preset settings between 8W-40W. With a RRP of just £30.00- US$35.00 you should give it a great deal of consideration when choosing your next Box mod design and for me- it’s worth every penny, sorry cent!
