This Milwaukee M12 Compact Inflator is seriously handy to have in your car or workshop! It can top off a car tire in under a minute and fill a light truck tire in about four minutes - way faster than those cheap portable inflators. The Redlink Intelligence with Truefill auto shut-off is brilliant - it stops automatically when it reaches your target pressure, so no more over-inflating or checking with a separate gauge. The digital display is bright and easy to read, showing both your target and current pressure. It handles up to 120 PSI, making it perfect for cars, trucks, motorcycles, bicycles, sports equipment - you name it. The compact size means it doesn't take up much space in your trunk, and since it's part of the M12 system, it uses the same batteries as your other Milwaukee tools. The high-efficiency pump and motor are surprisingly powerful for such a small unit. If you're tired of dealing with gas station air pumps that are always broken or inaccurate, this little inflator is totally worth it. It's become one of those tools I didn't know I needed but now can't imagine being without!
