How it compares
Compared to the AstroAI Cordless Tire Inflator and the DEWALT 20V MAX Inflator, the Milwaukee M18 Inflator 2848-20 offers superior airflow and a rugged construction built for jobsite abuse. While AstroAI models are more budget-friendly, Milwaukee leads in reliability and speed for heavy-duty users.
What to know before buying
- Ensure you already own or purchase an M18 battery and charger, as they are sold separately.
- Check the digital gauge calibration before first use — some units may need offset adjustment.
- Use the included brass tire chuck for a secure seal on valve stems.
- Store the inflator in a dry toolbox to prevent debris clogging the motor vents.
- Replace the air filter every 6 months for optimal performance.
"I use this on my F-350 dually and my side-by-side. Beats my old 12V compressor by a mile. The gauge is dead accurate." — Verified buyer
Sustainability & ethics
