AVID POWER Cordless Inflator
Ranked #4 in Best Portable Tire Inflators
AVID POWER Cordless Inflator
1 sourceall derived$52.78as of Aug 1

Around $70 buys the AVID Power's detachable 20V battery, a 12V car adapter for backup, a drill-style grip and a digital gauge, which makes it the budget cordless pick. Automoblog scored it 88/100. It runs slower and less rugged than the premium units, and some owners flag durability, but as an affordable, maneuverable inflator for cars and bikes the value is solid.

Strengths
  • — Inexpensive cordless inflator with a detachable 20V battery and 12V car adapter
  • — Drill-style grip is easy to maneuver around tight valve stems
  • — Filled a Camry tire from 20.5 to 35 PSI in about 2 minutes 32 seconds in testing
Watch-outs
  • — Some owners report durability and longevity issues
  • — Slower and less powerful than the Milwaukee M18 or Viair 88P
  • — Battery runtime is limited; not built for many tires in a row

Viair 88P
Ranked #3 in Best Portable Tire Inflators
Viair 88P
2 sourcesall derived$89.89as of Aug 1

Trucks, RVs and off-road rigs that get their pressures reset often are what the Viair 88P is built for. GearJunkie's testing had it filling tires in roughly half the time of the next-fastest unit, and Pro Tool Reviews named it best for trucks. There is no auto shut-off and it connects by battery clamps, but for serious heavy-duty inflation it is the value workhorse.

Strengths
  • — Crushed the competition in truck-tire testing, filling a 215/70 R16 from 10 to 45 PSI in about 3 minutes
  • — 120 PSI ceiling and a 25-minute duty cycle handle off-road and 33-inch tires
  • — Long 16-foot heavy-duty rubber hose with a quality brass chuck reaches all four tires easily
Watch-outs
  • — No automatic shut-off, so you must watch the gauge to avoid over-inflation
  • — Gets hot, up to about 160F after roughly 12 minutes under load
  • — Clamps connect to the battery, more involved than a 12V plug

How they stack up

AVID POWER Cordless Inflator

The budget cordless choice, cheaper than the Milwaukee M18 Inflator (2848-20) and the Slime Cordless Pro Power, with a detachable 20V battery and a 12V car-adapter backup. It is slower and less rugged than those and than the corded Viair 88P, but the most affordable cordless option here.

Viair 88P

The heavy-duty speed champion, faster on big truck tires than the cordless Milwaukee M18 Inflator (2848-20), the hybrid Slime Cordless Pro Power and the budget AVID Power. It shares the corded, battery-clamp approach with older corded inflators but reaches a higher 120 PSI for 33-inch tires.
