Customer Ratings & Reviews

i think work pretty good. i wish charge lasted longer.

So far the charge has lasted and they are easy to recahrge.

these batteries are so easy to charge and I like the way that they can be charged anywhere with usb

The batteries work well for switching out in keyboard , mouse, toothbrush, etc. The red green LED lets you know status. The caps are magnetic have not lost one yet. USB easy to find. Probably a little underpowered compared to a2800 or 3200. But a nitch product. I'll buy again

I have only used them once in a remote controlled toy car. The other batteries would last for 3-4 hours and these ones lasted for slightly above 2hrs which is kind of expected from re-chargeable batteries. But i totally like the ease of charging over USB.

I use it for work so I need to have no hiccups, and it doesn't disappoint.

Had a $25 rewards coupon I had to use or lose it. Bought these batteries and am VERY happy with the purchase. They stay charged longer than 2.4v rechargables and recharge quickly to 2.5v. An accidental purchase has resulted in a happy customer!

My wireless mouse was eating up batteries like candy. So I bought a pack of these USB AA batteries and they are lasting 5x longer than any normal non-chargeable I had used in the past. Love how you just plug them into a USB port to charge them.

We have the outlets with USB ports. So we plug them right into the outlet. Fully charged in a couple of hours. They have been in my sons Xbox remote for weeks. He plays hours at a time. Great battery. I will be buying at least one more set.

These USB charge batteries works good, and change fast

Im a blogger and vlogger and need to be able to charge my batteries right from my laptop. these work great. They hold a charge for a long time as well. I thought id have to buy a new camera. These saved me hundreds.

I bought these for refrigerator and freezer temp monitors. I had read that most batteries do not handle temps around 0 very well. These have been in use for 3 months and so far are holding up just fine.

I still use them! I was very sad when they were discontinued. Being able to charge batteries using something as ubiquitous as USB is pretty handy.

I purchased 2 AA and 1 AAA packages on sale at Best Buy they were easy to charge and I'm looking forward to not having to replace batteries in my sons games ever again I was going broke buying batteries before

I was skeptical about these but I tried them in my high drain Sony camera and they work great.. they hold a charge better than the Sony brand rechargable batteries that are suggested.

These are excellent batteries. They last for hours, and only take 2 hours to charge. I get about 19 hours of use on my Xbox one controller

Though I have just begun using these they seem to work fine. Hold a good charge. Using them in wireless microphone. I bought these at BB deal of day. Keep a watch and buy them on sale.

I have installed outlets with USB plugins for charging and they work great.. They take less than two hours to charge and seem to have a long life before needing to be charged again.

Works great with my remotes and electronics. Will not have to buy batteries often if these keep recharging when it goes out. Haven't had any problems or malfunctions yet.

I use them for the batteries in my remotes. It's the easiest rechargeable thing I have owned. Just pop the top and plug into a USB port and it charges. Simple genius
