Does the base have to be connected to AC dock, or does it have it's own battery so that it can be played outdoors?

The base is the "AC" dock and needs to be connected to both the transformer AND the source. Connection to the source can be either by Bluetooth or by cable which is included. The individual speakers remain on the dock until you want to move them outdoors or anywhere inside. While on the dock, the speakers are charged, as needed.

Yes. This unit has a battery and a small speaker in it. This unit can play stations using it's battery, small speaker, wi-fi signal, and an internet radio subscription. You will need the separate car kit to use this in a vehicle. The car kit comes with the dock, remote, & antenna. The dock will let you charge the unit and has a 3.5 MM AUX output, or you can use the built in FM modulator. The FM modulator only works while the unit is in the powered dock.

Yes it is rechargeable and it can play when being charged however if you are charging it then you have the back opened up the access the port for charging and should be careful then not to get it wet. The back cover has to be on for it to be water resistant.

Doesn't need a battery, will run standalone on AC. On a side note we love ours, still going perfectly.

It has a charging base that can be wall mounted or table mounted. It locks in when you dock it so it doesn't fall off.

You can charge it with an AC plug, but this cable needs an USB entry to connect to JAM. I never tried playing it while charging. The battery lasts reaaly long and everytime I need it I plug it at night. By morning is already working and fully charged.

No, it does not include a battery. It has an auxiliary jack so if you have a different phone than an iPhone for the dock then you can play music off of your phone, i.e. I used my Samsung Note II.

Hard to say with me. I usually just have it plugged in. But my son plays on it and leaves it running on the ground and it lasts for many hours.
