HP Powerup Backpack carries along a backup battery. But it’s not one just suited to your smartphone and smaller devices: the large lithium ion battery within boasts a 22,400mAh capacity, enough to fully charge most HP laptops, though it’ll also easily charge a tablet three times over or a smartphone up to ten times.
FAA regulations state that any battery over 100 watt-hours is prohibited in checked or carry-on luggage, but exceptions can be made “with airline approval.” The battery in the HP Powerup Backpack is rated at 84 watt-hours, so there shouldn’t be any issues. As the owner of a suitcase with a built-in battery, however, I can tell you different countries have different rules when it comes to high-capacity batteries, and it can raise some time-consuming issues.
Your laptop’s power adapter does double duty, also charging the pack when otherwise not in use, and two micro USB cables plus a laptop cable come included to charge several devices simultaneously. It’s also made of coated heavy duty canvas that’s water resistant and contains a pull-out rain cover for even wetter weather.
