Have used it once to charge my phone. Why? Because my cat knocked over my glass of sparking water and it splashed on my power strip. Had to wait until I could change the plug. Anyway, it is much larger than I thought and quite hefty. Not a big problem, it and the charge cord fit into my purse easily. I'm glad to have the backup!

It recharges fast and charges my phone with power to spare. It’s a nice size. It fits my life better than the expensive Goal Zero battery.

This doesn't have charge through which won't effect most users. I purchased this for outdoor lights with a solar panel to keep this charged. The battery does charge well. When I unplug the solar panel it lights up the lights well. I just wish I didn't have to keep walking out there to open up the water tight box and unplug the solar charger every night. When charging the bank it shuts off the ability to expell power to the led lights. It's frustrating but perhaps I need a different product all together.

I’m only giving it four stars because I actually returned it I ordered it and it was not delivered in a timely manner so I went to a local store and purchased one.My experiences with Anker are positive for one day warranty their products. Customer Service is outstanding.

This charger works crazy well. It supplies a ton of power to charge multiple devices. I fully charged my iPad and it only depleted the b charge bank by about 20%. It’s a perfect size to fit in my messenger bag or a carry on bag. It has a super strong feel to it, it slides not feel cheaply made. Anker did it again, producing yet another quality product. It is a great value and works flawlessly.
