Strong durable compressor. Also runs great when powered by NOCO Genius Boost 150. Vehicle mounted compressors are convenient to use. But they're limited being hardwired and mounted to a vehicle. I prefer a portable compressor that can be taken where it is needed. A vehicle has a flat offroad and it is not possible to drive alongside. Worse case senario a vehicle sitting awhile with a dead battery and flat tires. A portable compressor with portable power like the GB150 can be used indoors.

I have use the air compressor only once so far but it was very easy to use. Airs tires very quickly. Just remember to set the connection to inflate and not deflate, both very easy to use. I was initially concerned the coiled hose would be difficult to use. It was easy. The weight of the compressor was enough to keep it stationary while the hose was pulled.
