Alexandre Just a question, what do you mean by "limited life"? Is the laser life expectancy very short? Answer, if you please

Mixed feelings... Pros: * I practiced my soldering skills * Seems to work - but probably I will need to replace my battery (not included) for a better one. * Compass - worked very well in terrain - easy to level horizontally Cons: * No battery incl. Item's name and description is misleading (stating "Power Capacity: 20000mAh" etc.), 1st answer for the 1st Q&A question suggests that there is battery, etc. * Batteries suggested in Q&A (18650) do not fit in. There is no information, that there is only 60mm x 90mm x ~14mm room for battery - so the best fitting battery (according to some Q&A replies) is 126090 3.7V 8000mAh - much smaller than advertised 20000mAh * ONCE YOU CLOSE THIS POWERBANK'S CASE, YOU PROBABLY WON'T OPEN IT WITHOUT BREAKING SOME CLASPS. They are very stiff/rigid, not flexible at all - so instead of bending them a bit to open case, you will probably destroy the case (in places where the clasps go). Don't close it until you have mounted battery, soldered and connected all wires, placed correctly rubber and snap link! It's good idea to check if everything works fine before closing the case. * No manual - so you have to figure out by yourself how to assemble it and that solar panel should be soldered to S+/S- (not S1+/S1-) and battery to B+/B-. Not hard to guess, but manual (even some simple PDF/JPEG) would be helpful. * I also had to solder 1 cable going to LEDs - as it was not connected on one end (maybe ripped off during transport). * No screws included (2 to mount circuit board, 4 to screw the case) * I don't think it's waterproof - to many ways in for water * I installed some li-ion battery (new), 4000mAh, the only I could get in 2 days before my trip - it doesn't fill up whole room for battery, and is held by 2 stripes of reused double-sided tape - so it might come loose and even rip off some cables :-( After fully charging power bank it charged my 4000mAh phone only for about 20-25% - and I don't know if it's battery's fault or power bank's.

سؤال: How does this charger charge a 3.7V li-ion battery when the output is only 1.2V??????

السؤال بواسطة stasio على 2020-03-12 10:12:36

Alexandre It doesn't. It charges NiCd and NiMH only, AA and AAA
