The first few charges I had no problems. I recently have had this issue of the product not charging past the second light. Even with the double chargers.

After two years the battery takes days to recharge!!!

Size is much bigger what it looks like in the picture. I tried to return but they dont accept returns.

This charger blew up in my lap and caused some damage inside my truck. Definitely not happy.

This battery has an "on" button that has to be pressed to start charging, the battery automatically turns off when there is no load. The problem is when i charge my Iphone and it reaches 100% the Anker battery turns off however the phone is still on using battery so i wake up to a cell phone that has been plugged in all night with 85%. The second problem is i keep the battery in my backpack with the charging cable hanging out the side, when i need to charge my phone or camera i have the take my backpack off and press the button on the battery.

The quality of the power bank is not very good. The capacitance is not as good as the above. It’s not very easy to use. I don’t like.!!!

Bought my charger in April and now in August it barely works anymore. It was great at first but now drops to a single light indicating charge after the first use.

I was amazed at how many times i charged my phone the first 2 times i charged the powercore, but it seems to hold less and less each time and its only on its 6th or 7th charge since i have gotten it. Seems typical of power bank batteries though.

At first it worked well. Then it started to turn off after a few seconds once you attached a device. You would have to constantly check to see if it was still charging. Then it stopped charging

Great when it works. Mine broke after a week and is now a paperweight
