GBA-SP contains rechargable battery. Of course, recharger is included set of GBA-SP. However, the charger covers only Japan and United States(only 100-120V). I several times visit to European countries. Those countries are 220-240V area. I tried out to customize cable of recharger with USB-type.
What's it ?Recharge GBA-SP via USB.
My note PC entered Power-saving mode passed setted time. That means timer limitation can be set !!
