I have become a huge fan of the portable battery backup solutions. I have reviewed numerous ones here on the Gadgeteer and purchased numerous ones for family members. In fact I have 3 backup battery solutions right now among the items in my daily gear, so I am a fan. But all those solutions only work with my portable gadgets like cellphones, tablets, and Bluetooth gear. I have never had one that was designed to provide my laptop a backup battery because all those other solutions aren't beefy enough to handle a true laptop. Until now. Enter the Roving Power Professional Power Pack (herein after referred to as the 'Roving').
