I stupidly took it to Ali, it’s good that I managed to cut down 50% of the price in a dispute, I proved on the video that nothing works as stated, and the instructions are obviously delusional in meaning, so for $ 9 on the fact of a refund, lying around in a box, I charge her old ones 18650 from a laptop for flashlights sometimes, because enough of them in flashlights for a long time, it is no longer good for anything, it can’t even refresh old dead Ni-Mh batteries, as well as measure the capacity, charge Ni-Mh normally. So don't expect to get a 2 in one device. Only charging lithium at 300/500/700/1000mA without the possibility of accurately measuring the capacity during discharge, such a mode is not provided here. Definitely not worth your money. It is better to take a branded product, but forever and for only $80-100, if you use it often and a lot, it will pay off with more than the right charging and refresh, both Ni-Mh and lithium.
