Best portable tire inflators

Top pick: Gooloo GT160 Dual — 160 PSI, 35 L/min airflow and a 7,500 mAh battery good for up to 45 minutes of continuous pumping. That's enough to top off four car tires or rescue a fully flat one without hunting for a 12V socket, and the dual-hose setup makes it quick.

Who the others suit:

• DeWalt 20V Max — if you already own DeWalt 20V batteries; no separate charger to keep track of.
• Milwaukee M18 — the same logic for Milwaukee owners, with a bigger, faster tool-grade pump.
• Airmoto — the pocket-sized choice for a glovebox; fine for topping off, slower on a big flat.
• JACO SmartPro 2.0 — a precise digital gauge you can trust for setting pressures exactly.
• Ophanie cordless — a cheap, light spare to keep in a second car.
• Hyper Tough / Rhino USA 12V — corded and simple, no battery to recharge before you need it.
