The truth is this is a knock off of the beautifully made one on etsy.
This charger is listen for $49. It’s portable, charges things fast through usb c, has a great power capacity. Being able to have usb c with power delivery in a battery bank is wonderful.
Anker needs to be more specific in the instructions and/or the marketing. It's no wonder anker gave this power bank only an 18 month warranty period. A hassle for support and waste of $ at this point.
The 4 small indicator lights are not accurate, which extremely problematic as a backpacker. It needs a special charger and it does not come with one. I keep portable chargers for emergencies, and this doesn't hold a charge.
