A heavy-duty battery is integrated into the HP Powerup Backpack, with the capacity to charge a laptop up to 17,3”, a tablet and a smartphone. With power priority, the order in which the devices are charged can be controlled by the user. Straps and eyelets ensure orderly cable arrangement, allowing a smartphone to be used while it is being charged and the user is underway with the backpack. The exterior of the backpack is made of heavy-duty canvas, while the interior padding and durable straps provide comfort. Temperature sensors prevent the devices from overheating.
