PORTAIR PA1500L

Overview

Sold under the PORTAIR name by a seller called CNZHONGYAO, but with more real specs than most listings in this price range. It has a 250W pump rated at 10.5 L/min and 4500 PSI (310 bar), runs on 12V DC or 110V/220V AC through an external converter (which makes the converter easy to replace), and has overload protection and fan-only cooling. It weighs 9 kg (19.8 lb) and measures 360 x 250 x 400 mm. Set your pressure and it auto-stops; it also has an oil/water filter. The seller rates it at 1 min 50 s to take a 190cc bottle from 1800 to 3300 PSI, and 5 min 40 s for a 480cc bottle from 1800 to 3500 PSI, and recommends tanks under 1.5L (one spec line says 0.5L max). The error codes are spelled out: E2 means too hot (it auto-stops at 80°C, so leave the fan running and rest it 3 minutes), E3 means input below 12V, and E4 is a normal auto-stop at your preset pressure. The seller says the design passed 150 durability cycles filling a 700cc cylinder to 300 bar.
