I think this is an absolutely fantastic idea! As someone who gets through countless batteries and has put rechargeable into the charger overnight only to discover in the morning that it wasn’t switched on (yes, ok, I’m a fool!), the concept of recharging your batteries using USB gets nothing but the thumbs up from me!Flat batteries are the bane of my life and my frustration mounts as I race around the house trying to find the battery recharger which I put away in a ‘safe place’ after I used it last! I’d like to shake the hand of the genius who dreamt up these ingenious eco-friendly AA batteries that are recharged via USB. Hey, I use my computer everyday, so it’s not normally a problem to find a spare USB port to step up for recharging duty. These amazing batteries flip open to reveal a USB connector which simply plugs into the USB port of your PC. No bulky chargers or cumbersome cables are necessary. You can recharge your batteries as you catch up on emails or finish that important report for work.
