Quite poor build quality, there are identical ones at a large DIY chain that are much better for €5 and worth their money. These ones arrived almost all with some manufacturing issue, e.g. the plastic comes off on the charging lid, crooked type C, and others - and we got 6 in total.

Okay, they are good, however they could be a bit cheaper since their battery life on a full charge is not that satisfactory.

so far it works normally and it can light up a room. it can't turn night into day, but during a power outage you can easily do your work in a room for a few hours. As an emergency lamp it is ideal.
Because I read some comments that after charging it stopped working, I think it should be charged with old chargers that are not many watts.

ps: I am not an electrician or an electronics expert, nor do I know about current.

Simply awful.. I put it to charge, it turned on once and when the battery died, it was over. Poor construction for its price, overall a terrible choice. I would not recommend it..

It is very nice for its price to hang it inside the tent, it has satisfactory brightness, it doesn't blind you but it's not too bright either. I didn't have it on for a long time, just enough to see inside the tent at night, so one charge lasted me 4 days.
