It seems like someone returned the item I was using and sent it back to me after blocking it.
It looks a bit weak, but it charges quickly and efficiently.
I need to use it a bit more, but I'm satisfied for now.
However, there are some parts that seem like they might break if dropped.
I bought this product because I dropped another product and broke the battery cover.
I guess I should use it carefully so it doesn't fall.
Other than that, it charges well and is small and very nice.
I need to buy more 21700 batteries.
I bought two just in case.
It's cheap and good.
