Question: How do you recharge
Document: Worst product ...after only 3 used. It won't charge anymore... can't recharge the Anker BATTERY.
Purchased several of these for gifts. Recipients LOVE them!! Recharge any device that will charge from USB w/o having to have an outlet!! !
Handy little charger. It is rapid (as it claims) and I like that I do not have to recharge the unit often!
Bought this for my wife as a stocking stuffer. She keeps it with her at all times now without special trips home to recharge.
This is a perfectly-sized source of power on-the-go; light weight and carries a very good recharge for my iPhone. Love it!
This device works as advertised. It will recharge my S3 a few times before needing recharged itself, very useful if you cannot plug in for a day.
This Anker worked great for 2 weeks. Now it will not recharge when I plug it in and it is useless! Biggest waste of money.
Love this! My phone battery doesn't hold very well...can recharge my Android twice on one charge with a little left over.
this is such a great item - so convenient to have in your purse to recharge my iphone  - no complaints whatsoever - works as expected and what else can I ask for!
This is working great for back up. I have charge my phone and Ipod and still have not recharge should be able to get 5 or more charges out of it.
Answer: Using an Micro-USB cable (included) connected to any USB power resource like your Phone charger or PC USB port.
