iFresh 2200UBC Universal Rechargeable Backup Battery.  What genius! You can charge pretty much anything with this when you don&#x27;t have access to another charging method... iPhone, iPod, cell phones, digital cameras, video cameras, you name it! It&#x27;s so tiny, I keep everything in a small pouch and just stick it in my purse when I travel. That way I have a backup if my phone or anything else runs out of juice in transit. $59.99
