The package was simple to open and unpack its contents. It's mostly self-contained, with the air hose and nozzle packed in one compartment built into the case and the power cords in another.
I needed an air compressor in order to keep my 5th wheel and pick-up tires at 80 lbs. As you may know, this amount of pressure isn't always available at gas stations or supermarket chains. I went searching and at first found a Black and Decker battery-powered unit that also had a large-volume hose for blowing up rafts and tubes. I purchased that unit and during just the 2nd use of it, the cheap valve stem connect nozzle broke, never to be usable again. Not impressed with the quality of the product, I went back to my search and bought my second choice -- the above-mentioned Campbell Hausfeld inflator.
Even though it doesn't have the large-volume output, it does have adapters to do the job, and the tire valve stem connector appears to be of superior quality compared to the Black and Decker unit. The gauge goes up to 300psi and it is advertised to inflate to 230psi. Although I just needed it to inflate to 80psi, the top end made me more comfortable with the product.
This unit also has a 12-volt cigarette adapter for charging or running 12v electronics or other devices using an inverter, limited to 10 amps. Their documentation shows you can power an 8-watt TV for 14 hours and a 55-watt light for 2 hours. I don't have this need for now, but, again, it's a comfort to have that ability on the road full-time.
Today I attempted to top off my RV tires, taking them from 70 psi to 80 psi. All 4 tires had dropped the same amount over the winter. On a full charge, it took the unit about 20 minutes to accomplish the full inflation. This is actually quick for one of these small portable inflators. I had a machine a few years ago that would have taken over 2 hours to raise the tire pressure that much. The B&D inflator would have been over an hour for this exercise.
The second tire only partially inflated before running out of battery power. This is the only drawback I found with the CC2300 -- one full charge would only handle one pressure raise of 10 pounds. It would most likely do much better at lower pressures, say 32 or 40 psi, but for my needs, I may have to consider a more expensive unit. For under 50 bucks, though, it's difficult to complain.
For the time being I'm going to stick with this model and plan ahead for multiple charging sessions. Recharging doesn't take long, just about an hour or so, and my needs are simple.
For the price, I highly recommend the CC2300 model from Campbell Hausfeld.
