We went hands-on with the new ENERGI Backpack from Tylt, a company with products we’ve enjoyed in the past, in the video above. There are many power bags on the market that include built-in batteries to recharge your mobile devices while on the go, but we were quite impressed with these new backpacks from Tylt. They are hitting the market for between $150 and $200 at the end of March. They include a 10,400-mAh-lithium ion battery with the ability to charge up to three devices at once and dedicated pockets for your iPad, iPhone, iPod, and MacBook.
