Umarex entered the compressor market with the ReadyAir, an oil-free, air-cooled portable that skips the water buckets and radiators entirely: connect power, set the digital cutoff, and fill. The current ReadyAir Gen 2 keeps that formula, adds an inline dryer on the fill hose, and is designed for straightforward owner repair. It runs from 12V DC or 110V AC and carries automatic overheat protection, positioning it as the low-fuss option in the portable class for guns and small bottles.

Specifications come from manufacturer pages and named retailer listings; blanks mean a value wasn't published, not that it's zero. Fill-time figures are derived estimates, not lab measurements. Always follow the manufacturer's fill and duty-cycle guidance.
