HP’s new Powerup Power Bank Backpack at first sight may look like an ordinary backpack, but this thing can recharge a full-size laptop with a massive 22,400mAh battery. It’s that much of a battery that is enough to recharge a smartphone for 10times. The bag features ventilated pockets and heat sensor monitors and regulators too.
AA regulations say that any battery over 100 watt-hours is forbidden to be checked or carry-on luggage, but it may make “with airline approval.” The battery in the HP Powerup Backpack is rated at 84 watt-hours. I can tell you different countries have different rules when it comes to high-capacity batteries, and it can raise some time-consuming issues.
The back costs for $200 only, and carrying the bag internationally in the planes is also not an issue.
