The system will turn on, but only for a second before shutting off again. Ah, thank you. I found an awesome battery for the Game Boy Advance SP. I’ve been using it in my IPS modded kit along with the Everdrive Mini. I haven’t timed out how long I actually get on a charge but it’s at least a handful of 45 minute to an hour gaming sessions.
