Whether a student, professional, or road-warrior, it's worth having the right bag to carry all of your gear. The latest from Seattle-based Poros is designed with modern life in mind. The Tetra backpack keeps mobile devices powered on-the-go through its seamlessly-integrated charging technology with full LCD battery display.

Bags with built-in batteries are becoming more common, proving useful in situations where power outlets are unavailable. Similar to the AMPL Labs Smartbag or previously-reviewed TYLT Energi+ backpack, the Poros Tetra is designed with an internal battery that can charge multiple devices via USB. But unlike many other backpacks, the Tetra is less obvious with its cabling and technology. Users can store and access items without the nuisance of navigating around bulk.

Poros' technology package is slim and compact, weighing only about 0.5 lb (0.22 kg). A 10,000-mAh battery offers two powered connections: one pre-wired cable (either micro USB or Apple Lightning), and one open USB port capable of up to 2.1 A. The cables route to internal pockets in the front zippered compartment for easy access. As with the Tetra charges devices, an integrated LCD screen numerically displays the battery's remaining power and output rates.

When ready to recharge the battery, users need only pull Tetra's wall charger from its dedicated pocket to plug into a standard socket. It looks exactly like plugging a backpack into a wall outlet. But with the power source and all necessary elements already contained within the Tetra, there's less chance that critical cables would be left behind when leaving the house.

As with other bags made by Poros, the Tetra is not short on storage or substance. At 18 x 12 x 6 in (45 x 30 x 15 cm), this backpack is spacious enough to hold a full day's worth of gear without being too cumbersome to wear. Constructed out of 1680D ballistic nylon with solid metal zipper hardware, the Tetra is designed to be durable while still looking good over time. Wide shoulder straps and a top carrying handle are made with travel in mind – padded for comfort with reinforced stitching for longevity.

The Poros Tetra backpack is currently funding on Indiegogo, having raised 18 percent of its US$10,000 goal in just a day, with another 35 days to go. A pledge of $99 sets you up with one Tetra backpack, saving $130 off the estimated retail price.

If everything goes according to schedule, backers can expect shipments of the Tetra to start as early as this March.
