The OBD-II needs to be plugged into the OBD-II port of any vehicle 1996 or newer. The port is usually located on the driver side underneath the dashboard. It will run off the car's battery.

Both. I use it plugged in, but it has a spot for batteries that I haven't tested (looks like 2 AA? maybe 3?)

It's battery operated. But don't worry, it doesn't work with batteries, either.

It does not have a battery if that's what your asking. It needs to be constantly powered through USB and needs to be connected to a device that can use its drivers, otherwise it wont work.

Yes, it has to be plugged in. It does not come with a battery adapter. I had an outlet on my porch within reach, but most people probably need to use an extension cord.

It needs to be plugged in. The cord is about a foot long so really not portable.

Yes it must be plugged in. There's not a battery. Nice little receiver I like it very mutch. Works well on a large system.

It needs to be plugged into an outlet. There is no battery operation option. FYI: a steam room will corrode the electronics inside extremely fast.

It must be plugged in. But it does have a battery because there is a CAUTION: Risk of explosion if battery is replaced by an incorrect type.

It doesn't use batteries. It gets its power from the USB connection on the laptop or computer.
