Everyone has been there. You’re on a plane and your iPod runs out of juice. You’re on the road and your phone dies. If you don’t have access to an outlet you’re screwed.

One option everyone should consider is having a mobile power source that you keep in your bag or briefcase, and the PowerPak is a nice option. We tested it out and were pretty happy with the results. Charge it when you charge your phone, and you can feel confident when you hit the road that you have a backup power source if you find yourself in a tough spot.

The PowerPak comes with extensions for every conceivable mobile device, so you’ll likely be in a position to bail out your friends as well.
