USB Rechargeable AA Batteries 2800mWh Rechargeable Lithium AA Batteries 1.5V Double A Battery with 4-in-1 USB-C Charging Cable and LED Charge Indicator, 4-Pack

My son got a Bitzee for his birthday and those things go through batteries like it is going out of style. I needed a rechargeable option so that we don't end up in the poor house. These have worked great. They have a really long life, even in the Bitzee, and they charge quickly so he doesn't have to whine that his toy is without batteries for a long period of time. I am stocking up on these and never buying a disposable battery again.

Bought these hoping they will outlast the alkaline batteries I've been using in my atomic clock. It is a pain having to reprogram it about every 6-8 months.

These are so cool! Battery life seems long. Crazy cool to plug into the actual battery instead of a bulky charging contraption. Size is only that of a battery! Bright color makes it easy to grab out of a drawer.

I bought these to replace the rechargeable battery in my mouse. However, my mouse doesn't seem to like them. I made sure they were fully charged, and my mouse says they're always charging, and yet the mouse works fine. So I don't know. The original battery never behaved this way, but it eventually stopped taking a charge so it had to be replaced. I don't understand the issue so for that reason 4 stars instead of 5 because something isn't compatible.

These AA rechargeable batteries with a USB-C port are a convenient solution for a specific use case I have. I use them for my beloved HHKB keyboard, which requires two AA batteries. It's frustrating when I'm on the road and the batteries run out. With these batteries and a simple USB-C cable, I can quickly recharge them and keep going.In the past, I carried a separate charger just for batteries, but the built-in charging feature of these batteries is vastly superior. While you do give up some battery chemistry quality (compared to options like Eneloops) and capacity, I believe the convenience is well worth it. Overall, the batteries have performed well for me, and I find the built-in design to be robust and perfect for my needs!

The reusable AA batteries are easy to use and charge up quickly. The batteries last a reasonable amount of time. It makes me feel good that I can reuse these instead of throwing away and purchasing alkaline batteries.

They last a long time. We;ve compared them to much more expensive LION rechargables and they hold their own

I started charging them and they smelled like some kind of a chemical attack happened in my houseI tried also using them in my flash, but they worked a bit and smelled the same when I took them out. When I put them into my flash for the second time, the flash gave out an error. I'm afraid they are gonna burst or burn my new camera flash. Refund.
