In this video, we are talking about a smart battery box that comes with 6 AA batteries and 4 AAA batteries. The batteries itself have more capacity than your regular batteries. Secondly, once they runs out of charge, you can just drop it back inside this box, and take out a fully charged one instantly.

The empty battery will get recharged in less than 30 minutes, and you can also fast charge using the Type-C port on the battery itself. All of the batteries can be recharged for more than 10,000 times before they finally give up.

What’s even more insane is that you can even buy regular rechargeable batteries online and use the case to recharge them.
