That would be a partially skiing related product review.

The iGo Juice70 is a multi function charger. It uses different tips (cheap) in concert with a multifunction transformer to charge/power your mobile devices. The Juice70 w/Dualpower will charge your digicam and laptop at the same time. Even in the car. It's the tits. And it's $60 (less than a laptop charger or the car charger for your cellphone sometimes)
