Summary

A drill-shaped tire inflator that runs on a 20V battery or a 12V car cord, so a flat battery does not leave you stranded. Check two things before you buy: the working pressure tops out at 50 PSI for car tires, and heavy use needs a 10–15 minute cool-down.

Strengths

  • Dual power is the draw: it runs on the 20V battery or a 12V cord.
  • Outdoor Life’s 2025 test named it the only inflator with both battery and cord power.
  • That tester measured 75.8 dB and called the compressor smooth, with little vibration.
  • Auto shut-off and a backlit digital gauge make topping up a tire simple.
  • An all-metal cylinder and metal gears read as durable for the price.
  • On-board storage keeps the hose, needle and nozzle together.

Weaknesses

  • Auto shut-off over-shoots the target by about 1.2 PSI on average in a lab test.
  • Cold slows it: at 28°F a test added 41 seconds and pressure dropped in the first minute.
  • Switching between battery and 12V mid-inflation means detaching the hose and losing pressure.
  • It needs a 10–15 minute cool-down during heavy use.
  • Heavier and bulkier than ultra-compact inflators, and the tester called the carry case bulky.
  • One owner reports a battery that stopped charging with no reachable warranty contact.

Dual power and real-world tests

Outdoor Life’s 2025 test of 10 portable inflators is the clearest evidence. On battery the ACAP115D-O reached 39 PSI before dying, hitting 25 PSI in 10:17; on the 12V cord it reached 25 PSI in 9:53 and the full 50 PSI in 23:56. Noise measured 75.8 dB at 18 inches. The tester liked the smooth compressor, backlit screen and simple controls, and named it the only unit in the test that could run on battery or cord.

A CustomerChoice lab test of five cordless inflators measured 1.2 PSI average over-shoot on target pressure. In 28°F cold-start tests it added 41 seconds and showed a pressure drop in the first minute, and it flagged the pressure loss when you switch power sources mid-inflation.

What it can and cannot inflate

This is a car-tire inflator, not a shop compressor. The working limit is 50 PSI for car tires, with a 245 mm tire-size ceiling; the gauge itself displays up to 100 PSI, so do not read the display ceiling as the inflation ceiling. It also handles bike, motorcycle, ball and inflatable duties through the included needle and nozzles. It is not meant for trucks, caravans or large-volume inflatables.

Battery, care and warranty

Charge the battery fully when it arrives and before first use, and recharge it every 3 months if it sits unused. A full battery lasted 18:14 to 39 PSI in Outdoor Life’s cold test, so expect to recharge mid-job on larger tires. The 12V adapter is not compatible with a Tesla Model Y built after roughly November 2021 because of its 16V battery. Warranty coverage is unclear: ShoppingTrends.ca lists 2 years, but no first-party Avid Power page states a period, and one owner reports a battery that stopped charging with no reachable warranty contact. No official parts channel was found.

Is it worth it?

At $59.99 from Avid Power Tools the dual-power design is strong value; competing inflators in the same test offered battery or cord, not both. Avid Power Tools lists the standard model at $62.99 and the yellow 30 L/M variant at $69.99, and Outdoor Life worked from a $60 price. The trade-offs are noise, bulk and the cool-down. Above $71–80, smaller or more accurate inflators become better choices unless the 12V backup is the reason you are buying.

Which model this is

This page covers the AVID POWER cordless tire inflator, model ACAP115D, sold in blue, orange and yellow colorways; the orange is listed as ACAP115D-O and a bare tool compatible with DeWalt 20V MAX DCB batteries is sold as ACAP115D-DW. The CAP334 is a different model with a 150 PSI maximum and an LED work light, so do not confuse the two. The listing ASIN is B0FM837VNM.
