I have the NAPA branded compressor, it has been modified to work with standard air chucks, quick connect power cable, etc, and it fits in the bag it came with still. I haven't had a problem with it getting so hot it melts the bag, but generally it only runs for short bursts because I use a portable air tank as a "ping" tank with it so that it isnt constantly cycling while airing up tires. I added a pressure switch to it, which was a great improvement, but it builds more air than a shrader valve can handle, so with just a short air hose and chuck it short cycles constantly. Great compressor for the money though, especially if you are handy enough to watch a youtube video and fix its short comings
