Which tires and batteries you are working with
This Milwaukee inflator is aimed at passenger tires, light truck rubber and other medium duty sizes, so start by asking what you actually park in your driveway. It can top off a 33 inch light truck tire in under a minute, which is the number that sets it apart from slower cordless units that crawl through a single tire while you wait.
The 2848-20 belongs to the M18 line, so your existing 18 volt Milwaukee batteries and charger are the pieces that make it run. If you are starting from nothing, the battery platform is a separate cost to plan for.
Milwaukee includes an all brass Schrader chuck, a Presta chuck, an inflation needle and an inflator nozzle, which covers tires, balls and small inflatables without a trip to the gas station pump. We'd consider those included accessories a worthwhile reason to choose this kit over a bare inflator.

What it will not do
This is a cordless tire inflator, not a diagnostic tool. It fills the tires you connect it to and does not read pressures on its own or explain why a tire is losing air.
Reaching a target pressure is not the same as confirming a tire is roadworthy. Treat it as a filling tool for the tires it is rated for, and leave pressure monitoring or repair to the equipment built for it.
It fills, it does not diagnose or monitor pressure.
It does not replace a tire repair or a dedicated gauge.
It does not run on household current.

At $165.28, the inflator sits below the typical price of $179.16 over the last 90 days, a difference of $13.88 or about 8 percent. That is a modest gap rather than a dramatic one, so the decision should rest on the M18 batteries you already own.
Owner feedback on this model is plentiful, with thousands of reviews behind it. That kind of volume tells you the inflator has been put to work in real garages, not just tested on a bench once.
The battery, hose and storage details to confirm
The inflator runs on an M18 battery, so check which packs you already have and whether a charger needs to join the same purchase. Nothing in the listing points to a power cord, because it does not use one.
Think about where the unit will live between uses. A cordless inflator earns its keep when the battery, chuck and nozzle are stored together, so plan shelf or trunk space for the whole kit.
The Schrader chuck threads onto standard valve stems, and the Presta chuck is the piece to confirm if you also pump bicycle tires.
Who should choose this and who should skip it
Choose this if you already own Milwaukee M18 batteries and want to stop hunting for a working air pump. The speed on light truck tires is the real reason to pick it over cheaper corded alternatives.
Skip it if you have no M18 batteries and do not want to start on that platform, since the battery and charger cost sits on top of the inflator itself. Skip it too if your only need is a pressure gauge or a diagnostic readout.
