Out of batteries… again
Almost every cheap computer mouse uses batteries for power and if you are using one every day then you have probably been in a situation where the batteries suddenly die and you realize you don’t have any new ones to spare. Suppose it’s after hours too and all the local stores are closed.
Nope. The only sensible way to keep your mouse powered up at all times is to get two sets of Ni-MH rechargeable batteries– one set for working, the other for charging (and then switch between those). They have become so cheap nowadays that they will earn your money back in just a few weeks!
USB Charger for AA and AAA rechargeable batteries
To charge your new Ni-MH rechargeable batteries you will need one last thing- the USB powered charging unit for rechargeable AA and AAA batteries! For less than two bucks ($1.99 USD) you’ll have yourself the extremely useful charging unit that will save you a lot of time and money spent on regular batteries. You can get them from here: ynef.net/ebay/charger
It even switches itself off once the batteries are fully charged to avoid explosions and other crazy shit!
