Powerbag Business Class Pack backpack with 6000mAh mobile battery

Sponsored links, if any, appear in green.

The Powerbag Business Class Pack looks like a typical, modern black backpack. It has a ton of compartments for your gadgets and laptop. It also has a 6000mAh battery.

That battery is the really cool part of the bag, since it is used with the built-in Apple and mini/micro-USB cables to charge your mobile devices. There's also a generic USB port available in one of the larger compartments so you can charge your tablet with its own cable. A power switch on the front of the back serves double duty as a battery status indicator.

That 6000mAh battery should be capable of recharging most smartphones at least four times before the bag itself needs to be attached to its own charger. It's possible to buy extra, swappable batteries in 3000mAh, 6000mAh, and 9000mAh capacities to replace the original or just to bring along as an extra.

There are other cool features of the bag that don't relate to the battery, too. My favorite is the pack's ability to unzip to fold flat so that it can go through an airport scanner without the need for removing the laptop. the fold flat feature gives the scanners a nice unobstructed view of your laptop, of which the TSA approves.

The Business Class Pack is available for $179.99 from Powerbag's website. It's expensive, but it can be a godsend for heavy smartphone users and those that rely on portable Wi-Fi hotspots.
