Which ONE+ batteries and valve you already own

This cordless inflator is sold as a body only tool, so the battery and charger you already run with your 18V ONE+ gear are the pieces that make it work. If that battery platform is already in your garage, this is the simplest way to add tire inflation without a second charging system.

The quick connect coupler on the air hose is the part you handle each time you top up a tire, so confirm your valves match the fittings you plan to use. We'd consider this a strong pick for anyone already invested in the ONE+ line and looking for a compact inflator that travels between vehicles.

What it will not do

This is an inflator, not a diagnostic tool, and a lower price does not tell you anything about a tire that keeps losing air. It puts air in, so a puncture, a bad valve or a slow bead leak still needs proper attention separately.

The high pressure rating is stated for tires and other inflatable items, and one-handed operation keeps the routine simple. We'd skip it if you need a tool that reads or clears vehicle fault codes, because that isn't what this device does.

What it will not do

It inflates tires and other inflatables; it does not diagnose leaks or read fault codes.

$10.06 (14 percent)

The price is $59.90, down from a typical price of $69.96 over the last 90 days, a saving of $10.06 or 14 percent. It has also matched its all-time low at $59.90.

Remember that figure covers the tool only. Your total cost depends on whether you already have a compatible 18V ONE+ battery and charger on hand.

The battery and storage question to settle first

Because this is the body only version, check that you own at least one 18V ONE+ battery and a charger before ordering, since neither ships with the tool. The compact, lightweight body is built to be carried and stored easily, which suits keeping it in a trunk or a garage shelf.

Think about where the hose and coupler will reach when you park, and whether the compact body fits the space you have in mind. Those two checks decide whether this inflator is convenient or just another thing to move around.

Who should choose this inflator and who should pass

Choose it if you already run 18V ONE+ batteries and want cordless tire top-ups without a cord or a separate air compressor. At $59.90 against the recent typical price of $69.96, it's a reasonable moment to add one.

Pass if you have no ONE+ battery or charger, since the body only format means buying into the platform first. Also pass if you need leak diagnosis rather than inflation.
