Portable air compressor(s)?

I use a Viair 88P, it works great for its size. Tremor tires hold alot of air!
 
I'm surprised no one mentioned one of these. I have one that lives in my truck...


Powertank is indeed awesome though. 8 psi to 30 psi in 40s on my jeep in abou 30 seconds.
I could buy 4 m18s and batteries for that price 😜

With the compressor plugged in start the truck step on the brake pedal and see if the plug has power.


How to Activate Power
For factory-installed Trailer Brake Controllers (TBC) on newer Ford Super Duty models (2017–Present), you typically must follow these steps to turn the power on: [1]
  1. Ensure the engine is running.
  2. Ensure all doors are completely closed.
  3. Plug the trailer securely into the 7-way socket.
  4. Press the brake pedal down for a moment. The truck's Trailer Module (TRM) will detect the trailer's electrical draw and activate the 12V charge line. [1, 2, 3]
This worked, well sort of. Using the 7 pin the RPM was noticably slower than when using alligator clips on the battery.

Pretty sure the truck isn't outputting enough amps through the 7 pin.
