When shopping for a PCP Compressor, be sure to buy a brand that has a resource for maintenance kits and repair parts. Don’t expect any PCP compressor to run maintenance free, and run forever!
Also, don’t get into the mind set of buying a PCP Compressor (i.e. Yong Heng from Walmart) and replace it under warranty everytime it has issues, because you didn’t maintain it properly.
I would recommend considering the Tuxing Brand, as they have a resource (Amazon, eBay, AliExpress) for maintenance kits, repair parts, and instructional videos to maintain their PCP hand pump and AC/12V DC Compressor products.
See the Tuxing Brand here:

I chose this direct fill compressor model for the built in AC/DC Power Supply, Digital Control System LCD display, Set-Pressure/Auto Stop feature and it operates Oil/Water free.
