Bags with battery chargers

Since you never know when you might be required to check your carryon, I think it's a bad idea to have a bag with a built in battery. How hard is it to just have a battery and cord in your "personal item" bag? Having it built into the bag is a PITA. If you need to use it while in the air it will be stuck in the overhead bin, inaccessible.

I always viewed that combination as "a solution in search of a problem". It also adds extra weight to the luggage, you need to remember to recharge your bag, it's a pretty big item to have tethered to your phone, and it's likely to be stored in an inconvenient place most of the time (overhead bin, trunk of car, hotel room).
