USB Rechargeable AAA Batteries,450mAh AAA Batteries with USB Ports - High-Capacity Batteries Long-Lasting Power Recyclable Recharge Battery -4pack

I was looking at several different rechargeable batteries for my husbands gaming controller to save money because so many batteries have been used and thrown away. I did have a little trouble at first sticking the cord in the battery, but that was because it doesn’t stick straight in - you have to kind of stick it in slanted and then it goes right in! I think my favorite part about this is that the light on the battery turns blue when it’s done charging. Not the basic green, but blue. 💙 They charge pretty quickly, and it comes with a four-way cord so you can charge them at the same time :) So cool 😎

I got these for my mouse and TV remote control, no more buying batteries for me. I got these ones specifically because they can be charged via any USB charger. Nowadays if you have a phone you have one so no need to buy any battery chargers. They have some indicators so you know when they are fully charged.

I didn’t know rechargeable batteries could come in this form. It’s a great idea! I’ve had traditional rechargeable batteries, and the charger usually gets less powerful over time, so are some of the batteries. It’s a constant struggle to find good rechargeable batteries without paying top dollar for brand names. These usb chargeable batteries look much more reliable and they have been working great so far!

Batteries always needed, even better if rechargeable. My kids has lots of toys need this batteries. I like it because you can charge it almost anywhere a usb is available. It's convenient to charge it anywhere with the built in USB port without charging case. You can travel with this and not worry about charging case, and you can find USB ports everywhere around you. It's very practical too.

Love the convenience of the triple AAA batteries. It does not required a charger to get them charge , you can simplify plug them into micro usb cable that came with it and charge them up. It came with a micro usb cable that charge two batteries at a time , wish comes with two cables so I could charge them all at once, batteries holds charge very well . I used them in the remote for the viper drone. Save money for recharging them and green for our environment.

These batteries are really easy to recharge and use. They seem to work fine in any device. There is only one draw back. The total power that they can provide is similar to conventional batteries. This might be expected, since so much volume is used for the USB port being built in (instead of being dedicated to more battery).

Great quality batteries, rechargeable, convenient, and easy to carry. The rechargeable battery is a very good way to store electricity. It is also more environmentally friendly. I would highly recommend them because of their environmental friendliness, convenience, and competitive price!!

I have had regular rechargeable AAA batteries before, but one that has a micro USB cable to charge it is fascinating. This is way easier to charge, especially if you have devices in your car that require AAA batteries, all you do is to plug the battery into a micro USB cable, wait a few minutes and you are good to go! For faster charging I use a QC 3.0 to charge the batteries quickly.
