Hay mate, I just wanted to give you some advice from my time I've had mine. This unit is good for doing one or 2 tyres. When you get to the 3rd or 4th, the wiring gets very warm, almost not able to touch it. Mine has melted the circuit board inside the unit. The pumps are great, but they're under size on the wiring loom. It's crap. Mine doesn't stop now because the pressure switch melted from doing 4 tyres. They pump quickly, but you have to let it cool down after 2 tyres. I'm currently upgrading my wiring loom to a heavier duty wire and relay and pressure switch. Which I would recommend to do when the warranty expires.
Does the compressor shut off automaticlly with the 3in1 mate? Thats neat if it does i got the exact same kit gonna mount it in me under tray toolbox when i get it built soon 👌🏽 awesome compressor though
