This unit has a problem that weems to be common to many regulated units going down to the sub-ohm level. It is not regulated, or not regulating well at all, at that level.
There is no explanation of the display in the KangerTech K-Simar 20 owners manual. If the voltage to the left of the battery symbol is the actual output voltage, then at 0.5Ω and 7.0W setting the output is actually between 15.7W and 23W, and sometimes spiking to 36W, as the voltage is consistly between 2.8V and 3.4V, with rare spikes to 4.3V. Judging from the burn when it spikes to 4.3V, it is the output voltage. The watt setting and resistance readings are unchanged.
I have also tried it with the KangerTech aeroTank2, and the aeroTank Mega, both at 1.5 - 1.7 ohms. Here it seems to function properly, as the output voltage is 3.3-3.5V, yielding 7.2W.
This could be explained by mode switching from DC-DC (DC to Dc conversion) to PWM (Pulse-Width-Modulation) modes of operation. I watched a you-tube review for the sigelei mini-box mod with the same problem, but no solution.
Aparently there is not a good solution for a vape that can handle both sub-ohm and >1.0 ohm. Also, we (3 vapers here) find the 0.1W increments to be an un-necessary gimmick, as the 0.5W increments have quite good for us for over 3 years now. It would be better to have a regulated unit with a range of 5.0W - 50W that could handle 0.2 ohm to 3.0 ohm wicks with 0.5W increments. At least that's what we're looking for.
I have attached an xlsx file showing what we like for power settings in a vape. Here: View attachment Power3.xlsx
