So, here's a problem I haven't encountered before. Whenever I plug in my DS Lite, it starts charging (the orange light lits up), but then after 10 seconds or so, it stops. In order to have it charging again I have to plug the cable out and then back in. What's causing this, and is there a way to fix it? Or maybe it's just the light itself which is disfunctioning, whilist the actual charging keeps on?
