Emergency disaster prevention hand-cranked self-generating flashlight solar charging treasure lighting multi-function


This flashlight can be charged by solar energy or by hand-cranked power generation. We have tried both charging and the results are good, but the 3.6V lithium battery in the flashlight has been damaged and cannot store electricity. It needs to be replaced by yourself, and the replacement is relatively simple. There are a variety of inexpensive lithium batteries available in our store, any 3.7 or 4.2V battery can work in it, 400mah to 800mah is recommended.
