I don't know if you would get Autel's entire Global data base for each car make for every model in every geographic region in the USA. I don't believe if the scanners have Chinese Car coverage available on USA scanners
The reason you pay more for the Pro updates is for 12 months of access to Autel Server to get BMW and Mercedes programming files, I don't know of any tablet based function the Pro can do,the regular Maxi can't do with the regular VCI ,because you need a laptop PC to use the Maxi Flash Pro VCI with an OE paid subscription for other makes if you need to do any J2534 device pass through programming .
