Lock it and leave it
Filling tires with air can take a while, especially when filling heavy duty truck or trailer tires with a smaller generator. That’s where a locking air chuck like this one comes in handy. Just set the compressor to the desired air pressure, lock the air chuck on the tire’s valve stem, and let the compressor do its thing. Now you’re free to do something more productive than bending over, holding a chuck, and checking the tire pressure over and over again with a tire gauge.
