I recently purchased a Yooo because I was so taken with the crazy shape. Unfortunately, after buying it and trying to charge it, I think it has the infamous bad charger connection problem. It flickers and appears to not have charged even though it's been plugged in for 24 hours.

I'm planning on getting a Fun Factory FOU and I know that their chargers are universal. My question is, does the FOU charger also have problems? Or does anyone have any other solutions? Is there a travel/factory lock I'm missing or something?
