Review: Kanger KBOX120

This slideshow requires JavaScript.

The KBOX120 is the first mod I’ve ever pre-ordered.  After the well received SUBOX Mini I figured it would be a home run for Kanger.  The new dual 18650 KBOX comes in 120w and 200w configurations of the same size.  Kanger touts the KBOX as being the smallest size in 200w.  It’s definitely thinner and quite a bit shorter than my Sigelei 150w.  My main goal with this mod was a more portable and pocket friendly dual 18650 mod.  


The aesthetics will be familiar to Subox owners.  It has the same look and color scheme as the original Subox.  KBOX120 is printed in gloss black on the top of the mod and a muted red Kangertech logo graces the side.  On the opposite side a series of vent holes in the shape of a K are cut in the C shaped battery cover and on the rear rounded edge the Kanger logo is also cutout.  Overall it’s a nice looking mod with a great form factor.  

A metal C shaped clip covers the batteries and is held into place by a small friction ridge that snaps onto the mod.  The battery tray is plastic but feels solid and well made.  The battery contacts are spring loaded at the top and curved cutouts in the battery tray make battery removal a breeze. The buttons are plastic and feel a little cheap or poorly thought out.  They rest right on the board and thus have a very shallow press.  I have seen opinions voiced that it is cheaply made or feels cheap.  While the C cover is thinner metal it is stiff and when the mod is put together it feels solid and sturdy with no rattling.  There is a slight gap between the edges of the battery cover and the top or bottom of the mod but it’s barely noticeable.

The 510 connection technically has a spring connection but has minimal movement.  The threads are recessed though which allow more depth before threading in.  My Zephyrus sits almost flush and there’s usually a couple mm gap on my VTC Mini.  I only have one RDA out of 12, a clone, that will not sit flush.


IMG_0013The KBOX 120 is capable of handling all the popular modes and is stated to be updateable via the micro USB port on the front.  It comes with temperature control modes for Nickel, Titanium, Stainless Steel, and NiCr.  The screen displays battery life via a visual gauge, voltage, wattage, and resistance.  In temperature control mode it displays temperature, resistance, and wattage.

By default in temperature control mode you cannot lock in the resistance of the coil and you cannot adjust the wattage from the set 120w.  However, it doesn’t seem to actually be set to 120w.  When using temperature control it seems to ramp up when you hit the button and never actually reaches 120w in my experience.  The KBOX also tries to recognize a new coil and seems to lock in the resistance on it’s own when it works.  Sadly it doesn’t often work but it still seems to keep the resistance held.  When it works, you get a “new coil?” message.  When it doesn’t work you have to unscrew the atomizer, hit the power button, and screw it back on.  Even then I only get the “new coil” message 30% of the time, but I am not sure it’s needed as the resistance seems to hold steady.


b7cf8e79-0d52-4708-80f3-f7eef27384a0I was only able to test temperature control with SS316L and Ni200.  Both modes passed the dry cotton test but the Stainless Steel mode was borderline.  It singed the cotton significantly more than the Nickel coil.  It did not catch fire though and I am not sure it is enough to cause a dry hit.  I have been using a twisted 28g SS316L dual coil build for a couple weeks now and have never had a dry hit as well as using a dual 28g setup in a tank with the same results.  I know everyone is curious about NiCr temperature control but I was not able to test it. Regular wattage mode works as to be expected.  I get a very slight delay after hitting the fire button but nothing outrageous.

The front facing USB port is in a good location for charging.  Kanger states that the KBOX will balance charge but I haven’t tried it for any length of time outside of making sure it starts to work.  The USB port is also said to be used for updates, but I have not seen an update yet and this is the first Kanger mod with that ability so only time will tell if any firmware updates actually get released.

Navigating between functions is done by pressing the fire button 3 times.  Wattage or temperature is adjusted by using the + & – buttons.  The adjustment buttons can be held to rotate the screen.  When a new coil is detected a message prompts you to press + for yes or – for no.  Press the fire button 5 times to turn on or off.

Pros Cons
Comfortable size and shape. Kangertech logo is muted red and doesn’t match buttons
Dual 18650 allows for longer usage before recharging Battery cuts off at 3.6v
Support for Ti, Ni, NiCr, and SS No wattage adjustment in TC
Upgradeable Firmware Doesn’t always recognize a new coil
Black or White backlit Screen
Simple intuitive menu navigation


The KBOX120 is a solid effort by Kanger into the higher wattage box mod market.  They took a lot of queues from their successful SUBOX and merged them with temperature control technology and 120 watts.  I was quite loyal to Kanger products when I first started vaping and was hoping to continue that loyalty once they caught up with the trend.  The KBOX120 meets my expectations on functionality and quality.  There are a few areas I would like to see improvement or updates on such as proven firmware support, lower battery cut off, better recognition of new coils, and coil resistance locking.  These are all more expert vaper requests though.  Kanger, in my eyes, has always been an functional and approachable entry-level brand and the KBOX120 succeeds in continuing that tradition.

Vaping since Jan 1, 2014. When I first started I was lost in the world of vaping. I didn't know where to begin. Once I found my way I wanted to help others on their path. So I started writing juice reviews on JuiceDB and eventually started reviewing new hardware I purchased. While I don't consider myself an expert, I am somewhat of a vetern of vaping, and I hope my casual-advanced vaper opinion provides you assistance. You can find me on Reddit as well under the user name sc0lm00.
