This kit pairs the Milwaukee 2848-20 M18 Compact Tire Inflator, Tool Only with the Milwaukee 48-11-1850 M18 REDLITHIUM XC 5.0Ah Extended Capacity Battery Pack — so you get a complete, ready-to-inflate tool instead of a bare tool that needs a battery sourced separately. Model Numbers: 2848-20 (tire inflator), 48-11-1850 (battery pack).

The 2848-20 is Milwaukee's fastest 18V cordless tire inflator, optimized for passenger, light truck, and other medium-duty tires. Rated to a max of 150 PSI, its high-efficiency motor tops off a 33 in. light truck tire in under a minute. TrueFill Technology runs an auto-pressure check that waits for pressure to stabilize, checks the system, and fills until the target is reached, and an Auto Shut-Off feature stops inflation at your selected PSI to prevent overinflation. It stores up to 4 PSI presets, and includes anti-vibration feet, a 36 in. hose with an all-brass Schrader chuck, and on-board hose and nozzle storage. It's covered by a 5-Year Limited Warranty and runs on any M18 battery.

The 48-11-1850 delivers up to 2.5X more run-time, 20% more power, and 2X more life than a standard 18V lithium-ion battery. Its pack construction routes water away from the electronics, minimizes heat to extend run-time and life, and resists failure from vibration or drops — including operation in extreme cold down to below 0°F/-18°C. Milwaukee's REDLINK Intelligence provides overload protection and discharge protection, and the pack is compatible with 60+ M18 cordless solutions beyond just this inflator.

Who should buy it? Anyone picking up the 2848-20 tire inflator who doesn't already have a spare M18 battery on hand — this kit gets you inflating tires the same day, with a battery that also earns its keep across the rest of your M18 lineup.

Skip the Battery Hunt — This Inflator's Ready to Go

Buying the 2848-20 tool-only usually means sourcing a battery before you can use it. This kit solves that in one purchase.

• Who it's for: M18 owners buying their first Milwaukee tire inflator, or anyone tired of pulling a battery off another tool just to top off a tire.
• Why it stands out: TrueFill auto-shutoff, a 150 PSI max rating, and a genuine XC5.0 battery bundled at $237.99 — buying the inflator ($199.00) and the 48-11-1850 battery ($169.00) separately runs $368.00, so this kit saves about $130.
• Worth knowing: No charger is included. You'll need a Milwaukee M18 charger on hand — or in your cart — to recharge the battery once it runs down.
