With so many power-hungry gadgets out there, small, portable power supply devices are all the rage. Sometimes I wish I had something that I could just strap on and have at the ready to power my GoPro or top off my iPhone or my DSLR. The GO PUCK folks must have been inside my head because their portable, wearable power supplies seem like they’d fit the bill. They offer three devices that each include dual USB output (Standard and Rapid Charging at up to 2 Amps), shock and vibration resistant rugged design, a 4 LED State of Charge Indicator, a 40″ micro-USB Active Cable and an Active Mount that lets you clip it to your belt, shoulder strap or other at-hand location. The 3X 4400 with mAh is $59.99, the 5X with 6600 mAh is $79.99 and the 6XR with 9000 mAh is $99.99. Visit GOPUCK.com for more info or to order.
