Overview
Milwaukee's -20 suffix on the 2848-20 marks this M18 Inflator as a bare tool that draws power from any M18 battery, built to top off a 33-inch light truck tire in under a minute. It includes a brass Schrader chuck, an inflation needle, an inflator nozzle and a Presta chuck for different valve types.
The real question before buying is whether you already have an M18 battery and charger on hand, since the tool itself will not run without one. It is tuned for passenger and light truck tires rather than heavy equipment, with the 33-inch/under-a-minute figure as the headline speed claim over typical 12V cordless inflators.
- Fastest 18V cordless inflator in Milwaukee's lineup, per Milwaukee
- 33-inch tire fill in under 1 minute
- Includes Schrader, Presta and inflation needle chucks
- Runs on any M18 battery
Who it's for
Fits anyone already invested in the M18 battery platform who wants a fast cordless inflator for cars, light trucks, bikes and sports equipment. Less of a fit for someone with no M18 batteries, since the tool alone will not run without one, or for anyone inflating tires larger than light-truck size.
Strengths and trade-offs
Drawn from this product's published specifications.
- Tops off a 33-inch light truck tire in under a minute
- Runs on the shared M18 battery platform
- Includes Presta chuck and inflation needle for bikes and sports gear
- Optimized specifically for passenger and light truck tires
- Sold as a bare tool; battery and charger not included with this SKU
- Not intended for tires larger than medium-duty light truck sizes
Performance notes
Filling a 33-inch tire in under a minute is the standout number, positioning it above typical 12V cordless inflators aimed mainly at emergency top-ups. The included chuck set (brass Schrader, inflation needle, inflator nozzle, Presta chuck) covers cars, sports balls and Presta-valve bike tires without needing separate adapters for most household inflation jobs.
