Auto & Tools: Tire Inflators, Car Covers & Care Picks

Editor's picks in Auto & Tools

ETENWOLF Vortex S6

The cordless inflator we'd pick for trucks and larger tires — its 19,200 mAh battery and 100% duty cycle are specs most rivals in this price range don't match.

AstroAI 12V Tire Inflator

The budget trunk staple: plugs into the 12V outlet, auto-stops at your target PSI, and costs about what a tank of gas does.

NOCO Boost GB40

The glovebox jump starter most buyers standardize on for 4- and 6-cylinder engines — spark-proof clamps and it holds a charge for months.

How we size up auto gear

For anything that inflates a tire, the numbers that matter are airflow (how fast it fills), duty cycle (how long it runs before it needs a cooldown) and power source — a 12V plug-in unit never runs out of battery but ties you to the car, while a cordless one works anywhere until the battery says otherwise. Max PSI matters far less than marketing suggests: almost every unit reaches car pressures; few move enough air for truck or RV tires.

For protection and emergency gear — covers, jump starters, TPMS — fit is the real spec: a cover sized wrong flaps in the wind, a jump starter under-rated for your engine won't crank it, and a trailer TPMS with short wireless range drops signal exactly when you need it. We flag those limits on each page instead of pretending one size fits all.
