Tire inflators, sorted out
A tire inflator is a small electric air pump that tops up car, bike, motorcycle, or trailer tires. The category splits into three families, and picking the wrong one is the most common buyer mistake: 12V plug-in inflators run off your car's accessory socket and offer the best value; cordless inflators run on tool batteries or built-in cells and work anywhere; and portable air compressors are the heavier 12V units built for trucks, RVs, and off-road tires that smaller pumps can't fill.
Below is the fastest route to the right model. Every recommendation links to a full review with our timed 28→36 PSI test, measured gauge error, and noise readings.

Heavy-duty 12V

From ~$70100+ PSI capable

Learn before you buy
Start with the buying guide if you want the full decision framework, or jump straight to a specific question: what PSI, CFM, and duty cycle actually mean, how accurate built-in gauges are, cordless vs 12V, or how to use an inflator correctly. If your pressure warning light is on, our TPMS reset guide and slow-leak guide cover the fix.
