The cell/mp3 charger that I modded worked great for a week, then it died. The circuit can't handle the current draw of an atty... well... it can for a while, then the smoke comes out.
The output on the solar charger is only 1 amp of current, it will work, but it will not last long before the smoke fairies suck the life out of it... For those that are not aware, SMOKE is what makes electronic devices work. You will notice that when it fails, the smoke escapes and there's no way to put it back in... I've tried.
I'm working on a couple of VERY odd mods that I hope will be completed by the Christmas Party.
Think "That was easy" and you'll have a clue about one of them.
