AVID POWER Cordless Inflator vs Viair 88P

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Viair 88P comes out ahead by a narrow margin (4.3 vs 4.6). The gap is mostly about truck, RV and off-road drivers who reset tire pressures often and want the fastest corded heavy-duty inflation — read the strengths below before deciding.

Ranked #4 in Best Portable Tire Inflators

AVID POWER Cordless Inflator

4.3

$70as of May 28

The AVID Power is the budget cordless pick: a detachable 20V battery, a 12V car adapter as backup, a drill-style grip and a digital gauge for around $70. Automoblog scored it 88/100. It is slower and less rugged than the premium units and some owners flag durability, but for an affordable, maneuverable car-and-bike inflator it delivers solid value.

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

Higher ratedRanked #2 in Best Portable Tire Inflators

Viair 88P

4.6

$90as of May 28

The Viair 88P is the pick for trucks, RVs and off-roaders who reset tire pressures often. 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. The trade-offs are no auto shut-off and the battery-clamp connection, 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.
