With many fans modifying their handhelds with power sucking features like modern backlit LCD's, running on AA batteries can become a frustrating exercise, as they rapidly run out.

esotericsean gets around that by modifying his Game Boy with a USB rechargeable battery setup.



Here are the parts he used:

The result is a USB rechargeable Game Boy that lasts for ages.

esotericsean reports playing the console for hours each day for a full week without running out of power.
