Good but with dents
The power bank in general is good. It provides fast-charging. As for the capacity, I am yet to test this during an actual trip where power source can be scarce. I’m a bit disappointed though, since there’s a dent underneath in this supposed brand new power bank. Makes me question if this is truly new as advertised.
