Would it be possible to add energy armor?
So that it uses energy (power) instead of durability, then if you get to 0% energy it'd begin using of the normal durability?
So you could charge it in a charging station or something? :)
That would be really kickass! :P

Edit: Perhaps it'd be charged by Electrical Outlets? :)
2x Edit: Maybe so if it's at 0% Energy, all the functions would turn off, and it would only protect you for the values that are on the armor itself :)
