Tuxing Dual Power Portable
Tuxing's lowest-priced portable and a steady Amazon seller (100+ a month). 4500 PSI, built-in adapter, 12V or 110V, auto drain. Manual shutoff.
Overview
An entry-level portable that sells 100+ a month on Amazon at around $132. The power adapter is built in, so it runs from a 110V outlet or a 12V car battery with nothing extra to carry. A 2800 rpm cooling fan starts automatically when you switch it on, and a drain valve purges moisture and sediment. It's oil-free, with no cooling water, and has an 8mm quick-connect. The listing gives no fill-time figures and doesn't mention auto-stop or a moisture separator, so treat it as manual shutoff and add an inline filter.
