Ryobi ONE+ 18V Dual Function Inflator review: buy or skip?

What the Ryobi ONE+ 18V Dual Function Inflator does well

The headline: inflator and deflator on Ryobi batteries. Key specs: Power: 18 V battery or 12 V; Max PSI: 150; Auto shut-off: Yes; Accuracy: Within 1 PSI. In our list it is the pick for: ryobi users. It usually sells for $49–$79.

Who it suits: people who own Ryobi tools.

The trade-offs

Good: high-volume and high-pressure modes, shares batteries. Not so good: battery sold separately. Read the skip-if line before you order: skip it if you do not have Ryobi batteries.

What to buy instead

Instead, consider the AstroAI L7 Cordless Tire Inflator ($49–$69): cordless inflator with auto shut-off and accurate gauge. Better if you want an easy cordless inflator for car and bike.

Instead, consider the Ryobi ONE+ 18V High Pressure Inflator ($49–$69): cheap inflator on ONE+ batteries. Better if you own Ryobi batteries.

Instead, consider the VIAIR 88P ($59–$79): tough 12 V compressor that runs as long as needed. Better if you want a durable inflator that never needs charging.

Before you buy

Auto shut-off at your set pressure prevents overinflation. Cordless models are easier; 12 V models never run out. Accuracy within 1 PSI matters.

US buyer tip

Check tire pressure monthly; underinflation hurts fuel economy and tire life.

Prices on Amazon.com move in a pattern. The deepest cuts land on Prime Day in July, Prime Big Deal Days in October and the Black Friday to Cyber Monday week, with smaller drops around Presidents Day, Memorial Day, the Fourth of July and back-to-school. Judge a deal against the usual price we show, never against the crossed-out list price.

Order from Amazon itself or the brand's official storefront so the US manufacturer warranty applies, keep your order confirmation and register the product with the brand. Most items can be returned within 30 days, and holiday purchases often get an extended return window into January.
