  • Here are the results of testing 13 USB power banks (including two wild cards). I compare them across about 28 criteria, including real world capacity, voltage drops, energy density, price and fast charging capability.

    Thanks to Franky for the USB Power monitor that was a huge value during testing: http://www.ebay.com/itm/USB-3-0-Power…
