Frequently Asked Questions about the Ryobi 18V Tire Inflator

What is the difference between the Ryobi P737 and P737D inflator?

The main difference is the pressure gauge. The P737 has a traditional analog dial gauge you must monitor manually. The P737D features a bright digital display with programmable auto-shutoff.

This makes the P737D more convenient and precise for set-and-forget inflation. The P737 is a more budget-friendly option if you don’t mind watching the gauge.

How long does the battery last when inflating a car tire?

Battery life depends on battery capacity and starting tire pressure. A standard 4.0Ah battery can typically fill 4-6 car tires from 25 to 35 PSI. Inflating a single tire from moderately low pressure takes just a few minutes.

For large truck tires or filling from completely flat, a high-capacity 6.0Ah battery is recommended to ensure you can finish the job on one charge.

Can you use a Ryobi tire inflator for a bicycle with Presta valves?

Yes, but you need a simple adapter. The inflator’s included chuck is designed for Schrader valves (like car tires). A Presta-to-Schrader adapter is a small, inexpensive brass piece that screws onto your bike valve first.

Once the adapter is attached, you can use the inflator normally. This makes the tool versatile for all your cycling needs, from mountain bikes to road bikes.

What should I do if my Ryobi inflator is not turning on?

First, ensure the battery is fully charged and clicked securely into place. Try a different, known-good Ryobi 18V battery to rule out a battery issue. Check for any obvious debris blocking the battery contacts.

If it still won’t power on with a good battery, the internal switch or motor may be faulty. Contact Ryobi customer service or visit an authorized service center for warranty support.

Is the Ryobi inflator accurate enough for road bike tires?

The digital P737D model is quite accurate for general use. However, road cyclists often need very precise pressure (e.g., 100 PSI +/- 2 PSI). The inflator is excellent for getting close.

For ultimate precision, use the inflator for the bulk fill, then finish with a dedicated floor pump gauge for the final few PSI. This is the best practice for competitive cycling.

What is the best way to store my cordless tire inflator?

Store it in a clean, dry place like a garage shelf or tool cabinet. Avoid extreme temperatures. It’s best to store it with a battery removed to prevent any accidental discharge or switch engagement.

Consider a small tool bag or case to keep the inflator, its hose, and your valve adapters together. This protects the tool and ensures you have a complete, ready-to-go kit.

Can the inflator handle large items like air mattresses or pool floats?

The standard P737/P737D can inflate them, but it’s slow as it uses high pressure. The Ryobi P747 Dual Function model is specifically designed for this. It has a separate high-volume, low-pressure mode.

The P747’s high-volume mode moves much more air quickly, making it the ideal choice for camping gear, pool toys, and inflatable furniture without straining the motor.

Why does my inflator keep shutting off before reaching the set PSI?

This is usually the built-in thermal overload protection activating. The motor has overheated from continuous use. This is common when inflating large-volume items or multiple tires in quick succession.

Simply allow the tool to cool down for 15-20 minutes. For future use, incorporate short cooling breaks during extended inflation sessions to maintain performance.
