Stopped working after the third recharged

I bought in April /16 and used only three times and stopped working. To charge the solar battery needs to have a little load. Otherwise it will not charge only the sun. I bought to leave on my emergency backpack  and now I can just thrown to the head of a bear. Waste of money.

Great charger. For the first few weeks. Now it won't charge anything. I'm not sure what happened to it. It lasted about 3 full charges, and stopped working. I hope I'm the only one who had this problem.

Edit: The seller offered to send me a replacement battery pack, which I accepted. Charges quick, much faster than my wall charger in fact. I must have had a bad unit, the new one works great. I'm also very pleased that the pack was replaced free of charge, and without having to send back the old one, great customer service.

It came partially charged.  It took almost 3 hours to fully charge from that point.  I used it twice, each time using the entire capacity until it was drained.  It worked fine those two times.  After recharging it completely I tried to use it for the third time.  It wouldn't work.  I tried it on 3 different devices with 3 different USB cables.  Those cables work fine on other devices but the item would not charge any of those devices.  Tried to charge item again.  It showed fully charged right away but I kept it connected just to make sure.  Five hours later tried to use it.  Nothing.  Item broke in less than one week.  Based on my experience, I would not recommend this product.

I used them like 10 times and suddenly they stopped working. The battery indicator says that it is still with charge, but it is not working at all. Recharging doesnt solve the issue and now i had to buy others from another vendor.

I only charged and used it 3 or 4 times. It just went completely dead after a few months. Stay away.

I was super excited to finally find a cute and well-reviewed portable charger to carry around for those extra long school days and this one worked fine at first. But the first time it "died" and I got to fully charge it I found that it stopped working all together. Now when I press the button it will show that it's fully charged but then shuts off a moment later and doesn't respond when I have my iPod or iPhone plugged in. I'm not even getting an error message on my devices (which can happen when the voltage is too low) it's just not giving any power at all.

It worked great.....once. I got about three iPhone 5 charges out of it. Now it won't re-charge anymore and I can't return or exchange it.

Initially, I was thrilled. Charger than is portable enough to extend my day.  Three days ago, it stopped charging, stopped lighting up when shaken and stopped charging my item.  This is the second Anker product that has failed me.  I am very upset.

I used it about 6 or 7 times to recharge smartphones and tablets and it worked fine. I could completely recharge two smartphones on one charge. There was never any indication the solar array did anything. Now it seems to charge but it will not provide any charge at all to devices. I pried it open and I get only 4.2 volts out of the battery. I would say the battery is toast. It's now re-cycle bait.

Loved it the two times I was able to use it. Went to use it a third time and the unit would not turn on or charge. It was promptly returned.

After the third time I used it, I recharged the battery then found one of the battery wires from the main unit had come loose.

i brought this back in may and was using it sparingly as a backup and care around when i travel. IT was great backup charger until it stop working. not sure why it stop working, it just stop. Its fully charged since the 4 indicating light are on. Its disappointing since i have it for a a few months. I was hoping it last me much longer. I even brought a few as gift for my friends and family members.i will have to reconsider buying AUKEY product from now on.

I might have just gotten a bad unit, but the quick charge stopped working after 3 months.  They have a 24 month return policy, and were quick to respond and send a new one.

I understand that not 100% of items manufactured are perfect, but good customer service goes a long way, which is why they are bumped up to 5 start IMO

I bought three of these for my grandkids.  Two have been returned already and replaced.  One of those replacements needs to be sent back already.  Now I'm just told that the other two aren't working.  They all have the SAME problem with the charging / battery issue.
Someone needs to fix this problem.  It's ridiculous.

Purchased this unit from Frys about a couple of years ago, and it gave good service. I particularly liked that it could be charged from a micro usb and would charge two devices simultaneously while being charged. Now it appears to have failed and will not take a charge. When plugged in for recharging, normally the blue leds all light in a rolling pattern to indicate that the bank is accepting a charge - but now when plugged in three leds light briefly, then two, then they go off. As nearly as I can tell it is a dead duck.

Followup: After leaving the unit plugged in overnight it began to accept a charge (the lights began to show the rolling pattern to indicate "charging") and now seems to act normally. Don't know what happened earlier, but I have changed my review up from three stars to four since it now works again.
