Review: Plugging in with the MOS Pack charging backpack

There's a growing number of bags that are designed to provide energy to devices while on the go. Many backpacks, such as the Poros Tetra, AMPL Labs Backpack, and TYLT Energi+, embed a USB battery to tap into. Successfully funded on Kickstarter, the MOS Pack charging backpack takes a slightly different approach by incorporating the company's power extension solution instead. We recently had the opportunity to check out what it's like to load up and plug in MOS's modern backpack.
