Can I use wire clips that connect to the car's inside 12V cigar lighter? Will that work as a power source to test the air pump without needing a transformer?

I keep a couple of old 12v transformers around for testing purposes. There are plenty of those from many kinds of devices these days.
If there is voltage at the connector to the pump, then maybe the motor is bad:
