Furthermore, HP has also taken care to keep the battery capacity well within the 100 watt-hours allowed by the airlines/FAA for carry-on luggage since the backpack battery is rated at 84 watt-hours. Again, it’s quite possible that the bag might be flagged since different countries have different guidelines. The bag doesn’t come cheap at $200 but considering the utilitarian front, it might be worth the money. Another good aspect of the bag is the compartments; HP has designed a separate compartment for each device alongside a charging port. The Powerup BackPack claims to charge your laptop fully and also comes with a smart management system that lets you prioritize the device that you need to be charged first.
