Ryobi P737D 18-Volt ONE+ Cordless High Pressure Inflator with Digital Gauge, 4.0 Ah 18-Volt ONE+ High Capacity Lithium-Ion Battery, Charger, and Bag (Bulk Packaged)

Have correct psi in my auto tires.

keep battery out of main unit when storing, the trigger is very sensitive and can drain battery inadvertently.

I never really expected it to work well. In fact it works speedily slow and steady.

My aluminum rims lose tire pressure every time the temperature drops. I dont have time to drive around looking for working air at the gas station. This portable device reads about 3.5 pounds higher than my tire guage, so I just adjust accordingly. The battery works for multiple sessions, and charges reasonably quickly. We also use it on our camper prior to trips.

Very easy to use! Tires were a little low on pressure and the ryobi inflator added it quickly. Highly recommend.

I double checked the digital read on the devises against two other air pressure measuring devices, both of which measured the air pressure about five pounds more than what the digital read out on this device indicated. It also was a little slow in bringing the tire pressure up, though this was not too troubling.

I received this today and it came with a 1.5aH battery and NOT a 4aH battery. It did NOT include a carrying case either.

Bought two—one for my Brother and one for my Son. They both stated it was a thoughtful gift that would come in real handy.

This seems perfect to pump air back into my wheelbarrow.

Great product
