Hi guys i found this 6600mAh Power Bank + Waterproof LED Flashlight at KD
judging by it size could it be use 26650 battery?
Maybe, but pricy.
yeah if KD could make it at $25
Wow, it dose cost a lot. I have this RAVPower 10400mAh which has more juice and much cheaper than the one you found. It only cost me $30 on Amazon.
6600 mAh? it’s probably 3 X 18650 - 2200mAh batteries
which you could swap it with panasonic 3400 batteries and it’ll give you 10200 mAh
but fasttech JinHeng much better… use your own batteries
i don’t know but judging by battery container it use 26650 maybe?
no… there’s no 26650 6600 mAh yet
