Need to hide in the bushes for eleven hours outside Megan Fox's house while taking the occasional super-zoom shot? Need to recharge your batteries but have no outlet? Energizer's portable charger clip is there.

This DSLR battery clip charges via a special USB source (like Energizer's own portable battery pack, which has a higher voltage than standard USB) and clamps on to "any" digital camera or camcorder battery. The compatibility list is probably high, but we're unsure if any actually means any, so check out the site before buying. The entire Energi To Go line will be available next month.
