Our take
The 2848-20 is Milwaukee's answer to the DEWALT inflator: a tankless M18 unit rated to 150 PSI that weighs about 7 lb. A retailer says it tops off 33-inch light-truck tires in under a minute.
Like all inflators, it cannot run nailers or air tools. We found no published noise rating.
If you're already on M18 batteries and only need inflation, this is the natural choice. For cordless nailing, the 2840-20 tank compressor is the one to look at.
Pros
- Runs on the M18 battery platform
- 150 PSI max
- Compact 7 lb
Cons
- Inflator only, with no tank for air tools
- No published noise rating
What it can run
This is a tankless inflator: it is built for tires and inflatables and can't run air tools.
Who it's for, and who should skip it
Best for: Fast truck-tire top-ups on M18 batteries.
Buy it if: you mainly top up tires, bikes and sports gear; you move it around often (about 7 lb).
Skip it if: you want to run nailers or air tools (it has no tank); you need to work indoors or near people without hearing protection.
How it compares in its class
- Ranked #3 of 3 in cordless.
- No published noise rating, unlike 2 of the 3 models in that list.
- Price band $150–$300; see every spec side by side in the comparison table.
Ownership tips
- Let it rest between long inflation runs; small inflators heat up quickly.
- Check its gauge against a separate tire gauge now and then, since built-in gauges can drift.
- Store batteries partly charged in a cool, dry place, not in a hot vehicle all summer.
General guidance; always follow the owner's manual. More in our maintenance checklist.
