I received a promotional email this morning for Indiegogo that included a portable recharging block. The thing that makes this one unique is that it has a 120v outlet in addition to the usual USB port. hought it would be a great way to recharge my P2 batteries in the field without buying DJI's car charger, plus I can run my laptop off it, too. They even have a phantom in their promo video!
