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

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!

For use in my old G602 mouse. Has already outlasted the last set of alkalines, and 2 more for other uses. Handy little charging cord, if not a little messy looking.

Great batteries that are easy to charge and they do it quickly. They also last a very long time for our uses. We use them in RC car transmitters and are getting 2 months of mild use and shelf life out of them. Haven’t picked one up that was dead yet.Not only do I recommend, I just ordered 5 more sets for other uses around the house and in toys.

Batter life is ok, not amazing. It is nice that they are reusable and can charge with USBC.

Works perfect and charges really fast

Fast and easy charge. Lasts longer than traditional batteries I typically purchase.

The battery life on these seems about 20-30% better than the average disposable brand battery. Personally I feel like this is a great deal for the price since you can recharge them without the need for a dock. I love that they managed to fit the charger in such a small space while increasing the capacity.10/10

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.
