Did you ever encounter that sinking feeling when you open the drawer on a Sunday night and there are no AA or AAA batteries? Well, this Cool Gadget will come to the rescue, assuring that you can charge one up and be ready to go.

These batteries charge pretty quickly and seem to last as long as more traditional batteries in my Oculus controllers for which I primarily bought them. I like that there is a single cable I need to hold onto and no bulky charging “box”. The design of having a charging port built into the battery is pretty cool.

These rechargeable batteries are so great! I found the first generation of rechargeables (that you have to put in a charger and plug in the wall) cumbersome, faulty and totally unsatisfying.
These are great, especially because of the charger wire that allows you to connect all 4 batteries to one USB plug. And the charge lasts much longer than other batteries. I bought a bunch for my window “candles” and have been super happy.
thank you for a great sustainable solution!

Being an older person means I need more light to see some things. I use an LED headlamp to provide that light, It uses 3 AAA batteries. With standard batteries, the light output fades as they run down. What I like about these batteries is the light output stays constant. The only downside is they only last about 30 minutes. To compensate for that I have 6 of them, 3 are ready to go while the other 3 are being charged. So far I'm satisfied with my purchase and would recommend them if asked.
