400P-RV EF Automatic Portable Compressor

It works. Got here fast.

I’m not sure that you can beat this unit for oortability, capability, and duty cycle time for filling RV and truck tires. Very well made and thought out product. 7 pin adapter is kind of genius.

Overall very high quality components. Would rate it 5 stars except for 2 items. 1: No manual included. Have to go online and download. 2: The air filter housing is a major pain to open! First, there is no indication of how it should open (twist? pry?). And that information isn't even included in the downloaded manual. I tried both twisting and prying but the cap would not budge, so I went back online and found a YouTube video of someone prying the cap off. With that information and after multiple attempts I was able to pop the cap off. Truthfully it takes the finger muscles of a Gorilla to get the cap off. Then it takes just as much effort to get the cap back on. I really don't get it. Everything else in the kit, from hoses to gauges to connectors, are well done, sturdy, and easy to use. The filter cap situation is a bit of an embarrassment to the rest of the kit. I will say that the one in the YouTube video appeared to pop off more easily so maybe mine is an anomaly but I sure don't look forward to having to get this off again when the filter needs replacement!
