My new TS501 won't power up unless plugged in. It powers up when plugged into the included power supply, the USB port, or the OBDII port. I have left it charging for a few hours.
When I got it, I applied the updated software available.
It is able to read my current TPMS codes from my factory tires via OBDII. However, I have not been able to successfully trigger and read my new winter tires with Schrader S074 28203 315HMz or the factory tires. I am unsure if that is related. I had to run it off of a portable USB battery pack when trying to trigger the tires.
