I have the Autel MD 808 Pro. Had it for 2 years now. Will do real time data with live graphs. It's not battery operated. It powers up once you are connected into the ADL port on the vehicle.
Price at the time was $275 and I get free updates for life. This one does not have the capability to reset the TPMS. There are units that just do that or get into a higher priced scanner that includes that capability.
