For those on the go, the biggest barrier to carrying around multiple electronics is battery life. Or, as the ski instructor from South Park would say, if your tablet or smartphone dies and you don't have access to a power outlet, you're gonna have a bad time. One possible solution is lugging around a battery. The other is buying a specialized backpack like TYLT's ENEGERI+.
The ENERGI+ isn't anything fancy, but simplicity was the goal. It's a poly material backpack with an inbuilt, 10,400mAh rechargeable Lithium Ion battery, 13 pockets, a trolley slot, a headphone carrying compartment, and a full-length zipper pocket. It accommodates any device with MicroUSB, and TYLT says it can provide up to 4 full smartphone charges or 1 full tablet charge.
The backpack normally retails for $199, but you can obtain for $149 using the code ENERGI50OFF through March 7.
