I used to be able to charge both my 3DS and my powergrip accessory at the same time by turning the backup battery on and plugging it in, but now when I try this for some reason it seems to short out and stop charging anything altogether. So far the only workaround I have found is to plug in each device separately. The stangest thing is, when I remove the charger from the wall socket and plug it back in, nothing happens, and it just keeps not charging anything, regardless of if they are plugged in separately, but if I plug in another device into the wall, such as a lamp or my phone charger, it works fine, and after that the 3DS charger works on both the 3DS and the Power Grip, but shorts out again when I try both together. What is going on here? Can anyone explain this to me?
