As long as you can get to your charging port, then yes you can. This is simply an extarnal battery that your charging cable plugs in to for power, instead of an outlet. It comes with charging tips for samsung, iphone, and micro usb.
Based on the picture from RAVPower for your 8400mAH battery, it appears to be a microUSB connection. If you have an android based smartphone or a newer Blackberry, these use microUSB cables to charge and connect to a computer/laptop. If you don't have a microUSB cable, these are cheap, or ask your friends as they probably have spares to give away.
I've never had an issue carrying external battery packs; they're treated the same way as regular chargers. Make sure not to use cellphones and the like at any point in the plane unless they allow you to do so though.
