So check out these AA batteries that plug into a USB port and charge.
You pop off those green lids and put them into a USB port!
They fully charge in about 5 hours. Not the quickest but great if you need AA while on the go!
They have a built in charger so you can just take them out of whatever device they’re in and plug them into the closest USB port. Bang!
My Logitech mouse uses AA batteries. This would be a great way to make sure I always have juice for it!
Some of my other peripherals use AA batteries, like my portable Apple keyboard.
We use Duracell rechargeable batteries around the house. I have a simple system where I’ve “borrowed” one of my wife’s food containers that has two sections. In the drawer under the charger I keep charged batteries on one side and uncharged on the other.
Here’s a picture of the batteries in the USB port.
