Inside the standard looking exterior of the HP Powerup Backpack you’ll find everything you need to charge all of your devices on the go. With a high-capacity 22400 mAh battery, you can fully recharge a laptop, a smartphone up to 10 times or a tablet up to three times. A built-in heat sensor and clever cable routing make it easier than ever to charge all of your gadgets without having to worry about over-heating. The heavy-duty coated canvas exterior gives the approved in-flight carry-on some light protection from wet weather, but there’s also an included raincoat for really bad weather. The only caveat for this otherwise good-looking and functional bag is the fact that it’s only designed to work with HP laptops.
