Is the multiplexer powered threw obd port? If so how many amp charger do I need to keep battery charged during long service? I have 8amp charger connected and it still runs out of power.

Yes, it is powered by the OBDII port. For most general diagnostics, it's no necessary to use a charger. For some operations, it knows it will take a while and will tell you to make sure it is on a charger.
