The 8000mAh LiPo battery plugs into a specific port on the Pine. If you also have your power supply plugged in, it will recharge the LiPo battery! So it will be ready to go when you want to go portable 
It is not a power bank, the latest update shows/mentions a power bank, but that is a separate thing.
If you are buying two Pines and want both to be portable, you may want to get two of the batteries. However, if you are only ever going to be taking one Pine around, and the other will likely be static/stationary, then you really only need one battery.
The air mouse remote, you can point it at the tv screen and the cursor on the screen will correspond to the position of the air mouse. Useful if you are using the Pine on a tv screen, not so much on a portable unit.
The basic remote is for media functions, I think. Haven't really looked into it, though...
...just sourced a faulty original Gameboy for cheap! Woohoo!ヽ(°◇° )ノ
