How To Charge Your Neo Geo X With A Separate Adapter (No Docking Station Needed)
UPDATE: I encountered a strange Neo Geo X issue today. After a month or so of not playing too much, the unit was completely dead. Showed a dead battery, wouldn't load up on the tv and didn't seem to be charging. I eventually let it sit on the Sony charger for a few hours and on the station previous to that. It's now at a 100% charge and works great. So it looks like this method of charging does work perfectly, and may have even helped me out with my charge issue this morning. =) - 10/30/13
Supposedly you can use a USB charger from the PC to Micro USB/Neo geo X, but I don't trust that completely. So I decided to pick up a PRSA-AC1, UPC 027242809062, Sony E-Reader Charger.
The Adapter is 5V 1.5A/1500mA.
