I’ve got portable chargers for my cell phone, portable chargers for my iPod, portable chargers for my little video recorder, portable chargers for my AA batteries… The only thing I don’t have a portable charger for (besides my laptop) is my DSLR, because it takes those annoyingly square 7.4 volt battery packs that require their own special charger. Energizer is about to solve this problem with a little clip that has teeth to attach to the contacts of battery packs of any size. The other end can be plugged into a USB port, and if I may say, props to Energizer for not making it some kind of proprietary plug.
Unfortunately, I’m pretty sure that you can’t charge a 7.4 volt DSLR battery out of a 5 volt USB port, which means that you’ll have to instead use one of Energizer’s new line of XPAL universal power packs (out next month) that come with 8.4 volt outputs. Nothing wrong with that, though… The battery packs looks pretty useful, and some of them even come with solar chargers. We should be seeing a review unit sometime in the near future, and we’ll keep you updated.
