Customer Reviews of 2600mAh Universal Power Bank Backup External Battery Pack Portable USB Charger blue
Fully Charges but bad USB Cable1/15/2014
The unit works great if you have your own USB charging cord. Plugged it into the wall or PC with the supplied cord charges the batter unit fine. But, when you plug it into a phone or tablet you need to use your own USB charging cord. The one that is supplied is weak and will not charge devices.
Box says, in English, "Warning if do not follow these instructions it may cause fire, electric shock, damage or other hurt. (sic). " Well the directions, if that is what they are on the box, are in Chinese. Granted you should probably just have to plug into a USB port, but is there danger of overcharging? Who knows. Also the description leads one to believe there is a light ("It also has a built-in battery which comes in handy in dark places. (sic)"). The box shows one as well, but there is none. Back it goes.
Nice and handy but slow charger12/18/2013
Its nice and handy but it took like for ever to charge my phone. In about an hour or so, it could barely charge about 20% for my Samsung S3. But for the price I paid its okay. Its like - you get what you paid for.
Just plug and ready to use. Works perfectly.
