Received a Kanger Kbox yesterday. I bought it not because I needed it, but because I was curious about a no-screen cheap mod. As one UK dealer had a very honest price on the Kbox, about 24 british pounds, I decided to buy one. I normally vape on Nautilus and Nautilus minis, on a Sx mini and Sig mini. I begun to vape years ago to come off tobacco and shortly turned into a "vape hobbyst" if this is the correct description for someone who owns too much vape gear.
First thing first: I believe it is incorrect to compare the kbox to any other "proper" mod, because it isn't. I would rather compare it to an advanced vape battery, just like the Aspire CF Mod, or the Innokin CLK!. The price is almost equal among the three devices I mentioned. Consider that any decent spinner battery is in the same price range, and an iStick mini (the 10W dwarf) is more expensive.
This said, the quality of vape of Kbox is at the level of Innokin MVP. Pure DC drive, buck-boost converter without PWM, efficiency around 95%. The only negative note is that there is a notable power loss produced by the steel spring in the tailcap above 20 W power level.
After being "burned" with the iSticks and Sigs sending mixed waveforms (because of PWM use) to the coils, any "proper" device using DC power is very welcome on my part... especially at this price point.
Second, the selection of power levels. It seems that somebody spent some time to find the correct "sweet spots" mostly used for vaping. On a Nautilus only the first three levels can be utilised, and they match almost exactly the levels I have in memory in my other mods. This "coincidence" made me devoid of need of fine adjustments, as they were already adjusted to my requirements. Now, how true this can be for everybody, I can't tell; but the power levels are chosen with a grain of salt, at least. And, BTW, the power indications are correct with a +-5% tolerance -from my measurements.
The semplicityb of the adjustment and the battery gauge has its attractiveness. Many persons with low sight will prefer the kbox because you don't have to wear glasses to see the screen (Like me). But it ended up in the drawer, why? Because I don't like to switch batteries. Think like a normal user, which is not an "hobbyst" but just needs the nic, and are the majority of vapers: he/she uses the same charger for everything, and don't take along spare 18650 and xtar charger in the morning. In my opinion, the biggest negative of the kbox is the lack of charging port, because it adds 30 pounds to the initial purchase, and force people to carry spares, and to screw-unscrew the tailcap - whose threads are not of excellent quality, and needs lubricant once in a while.
If kanger is reading this -please add a charging port!
