No there isn't. Only an adapter jack for the option if plugging the machine into the wall or using batteries.

None, the systems ships with only the power adapter. I recommend getting a USB 3 Port replicator with/without power.

Yes you can charge without a computer if you plug the wall transformer plug in.

No. The accessory doesn't care what device you are charging, it just provides power. Make sure the Powerstation is completely charged to 4 dots of charge before you continue.

It does not use any battries, its just plug into power source and thats it. Nice machine.

Yes they can all be used to power devices without a computer but the amount of power each port has is very low compared to what a device would get from its own ac adapter.

It has it's own power supply so I have not had any problems with powering anything. Also, since it has a separate power supply, it charges things while the comp is turned off. I highly recommend this unit.

They are not necessary. I have been using the elliptical for several months with just batteries, but frequent use and multiple users might warrent purchasing the power adapter.

No, but you can easily power your circuits with a separately purchased battery pack or AC power supply.

I haven't tried charging another device from this but the operation does not need power supply. Simply plugging in to the USB port is sufficient to run all the functions.

Yes, but I have never used the batter power. I have always plugged the machine in to a power outlet.

Yes, the amp can work just with the power adapter. But if the battery is charged, it can also work for a couple hours without being plugged.

You can use it without power. I haven't tried using it with multiple sticks without the power adaptor though.
