Does the auto shut-off really work?

Yes. You set the target pressure on the digital gauge and the pump stops when it reaches it. Buyers report it working reliably.

How fast does it fill a car tire?

Buyers report about two minutes to go from 23 to 35 PSI on a car tire. Large RV or truck tires take longer.

What comes in the box?

The inflator, a 20V battery and charger, a carrying case and three nozzle attachments. The 12-inch hose is attached to the pump.

Can it inflate bike tires and toys?

Yes. The three nozzle attachments fit bicycle tires, sports balls, air mattresses and pool toys as well as car, SUV and RV tires.

No written warranty is included. Check the retailer's return window if coverage matters to you.

Does it need a power outlet?

No. It runs on its 20V lithium battery, so it works away from an outlet. Charge the battery before a trip.

What reviewers say

Buyers describe the Stalwart as quick and easy to use, with the auto shut-off working reliably and a car tire gaining about 12 PSI in roughly two minutes. Several say it solved tires that were always a pound or two low. The main complaint is unclear directions, and one owner hopes the 20V battery outlasts the 18V model it replaces.
