Extreme Portability

Thanks to the 18-volt lithium-ion battery that’s responsible for producing up to 150 PSI of air pressure, you do not need to connect the  P737 to an air compressor, nor do you need to plug it into the wall. You can take your Ryobi with you on any job at any location, even those without electricity.

Brushless Motor

The P737 features more modern technology in the form of a brushless motor. The brushless motor is a modern design of the electronic motor that removes the internal brushes to deliver more power with less friction and maintenance. Less friction also means a cooler running tool and less drain on the battery, which allows them to last up to four times longer on a single charge.

Digital Display

The easy-to-read digital display offered by the Ryobi P737 is an improvement over many other brands that use an analog dial gauge. Analog dials often contain tiny markings that can be difficult to read, especially in low light conditions, and there is also the question of their accuracy. Digital displays, on the other hand, are extremely accurate and rarely require recalibration. The one included with the  P737 is nice to look at with a blue screen and black numbers, letting you know exactly what the tool is doing.

Here are some of the questions we find that many people ask.

Will the battery last long enough to inflate four SUV tires from 15 to 36 pounds?

Yes, you should be able to fill four tires on a single charge, though you may notice the unit has become fairly hot.

Is it strong enough to remove dust from a computer fan?

No, that is not the way you use this tool. It doesn’t move a large volume of air quickly enough to blow dust; it creates up to 150 PSI of pressure in an enclosed space.

Does the Ryobi P737 deflate things?

Unfortunately, there is no reverse on the Ryobi P737 to deflate objects.

Can I use it to fill motorcycle tires?

Yes, you can use it to fill any objects that require an air pressure between 0 and 150 PSI—including motorcycle tires.
