Hi! Even though I have a perfect AGS-001 I don't think I can get the GBM Famicom Edition out of my head. I've never used generic USB chargers before and it's impossible to find an official GBM charger that fits Norwegian outlets. Not going to bother with a converter so I thought I might as well get a cheap USB charger. My question is - can I just use the USB charger with an iPhone/iPad adapter or will it kill off the battery? Thanks!
