Smart Phone Portable Battery Pack

Hello,

Just curious if anyone has built a robot before that used one of those external smart phone battery packs.  Seems like an easy way to provide a rechargeable source.

Something like this: http://www.amazon.com/Photive-2600mAh-Portable-Battery-Charger/dp/B00BFY59BA/

Thanks,
Scott

Thanks, I wasn’t really looking at that model specifically.  That was just the first one that came up when I searched Amazon for an example to put on this forum.
