DeWalt DCC020IB 18V XR / 20V MAX Cordless Tyre Inflator (Skin) vs Milwaukee M18BI-0 18V Cordless Tyre Inflator (Skin)

Pros

• + Runs off an 18V XR / 20V MAX battery or the car's 12V socket
• + Up to 160 PSI - the highest pressure here, plus a high-volume mode for big 4WD tyres
• + Deflate mode as well as inflate - rare at any price
• + Digital preset gauge with auto shut-off, LED light and onboard accessory storage

Cons

• − US-spec import - the 110V AC mode does not work on Australian 240V mains
• − Warranty terms vary by Amazon AU seller
• − Heaviest and bulkiest unit on the list, and the most expensive

Pros

• + Fastest 18V cordless inflator in the class - a 33in light-truck tyre in under a minute
• + TrueFill preset auto shut-off stops dead on your target pressure, no babysitting
• + 150 PSI ceiling covers trailer and light-truck tyres that 120 PSI units can't reach
• + Australian-spec M18BI-0 with the local Milwaukee warranty path, not a parallel import
• + Brass Schrader chuck, Presta chuck, needle and nozzle all stored on board

Cons

• − Sold by a third-party Australian tool retailer with only a handful in stock, and no delivery to Darwin when we checked
• − Bigger and heavier than a compact M12-class unit - this lives in the ute, not the glovebox
• − Skin only - needs an M18 battery and charger
• − Fewer Amazon reviews than the DeWalt and Ryobi inflators so far
