ROCGORLD R8 Tire Inflator Portable Air Compressor, DC 12V Air Compressor Portable with Large Dual Digital Screen, 3X Faster Inflation Air Pump for Car, Bike, Ball, Motor

Très bien

Purchased this unit to replace a similar item that was battery powered. The battery powered unit worked fine initially, but after only a few years the battery did not hold a charge long enough to inflate even one tire a few pounds. Decided to go with this 12V unit and have been impressed. Plug it it to a 12V outlet in the car, start the vehicle, set the desired tire pressure and it works great. Powerful, convenient and easy to use. Once the desired pressure is reach the Inflator automatically shuts off. Filled all four tires about 6 pounds each in a matter of a few minutes. Everything easily fit into the storage case and underneath my car seat. Only downside was there was not an adaptor that would fit my road bike tire valve stem.

Worked as expected. Amazon's same day delivery saved my road trip. Needed a tire inflator ASAP and a good quality one. This fits the bill... compact, easy to use and had features like auto shut-off when the PSI reached your desired pressure (Default is 35 PSI). Worked right out of the box.

Very quick & easy to use. I love the fact that it's compact and came in a carrying bag. So far so good. The only thing is that the tire pressure numbers that I preset are off by maybe 2 on my actual tire sensor numbers. For instance, I preset the pump to 34 but once the pump auto shuts off when said pressure is reached, my tire sensor numbers read it was only 32. But once I start driving, the numbers will sometimes go up to the preset pump number) its a little noisy but overall, I'm glad I made the purchase. Very useful and helpful to avoid having to find gas stations with working air pumps and it saves money & time. Great to have especially in cold weather where tires deflate a little more often in this season.

This slim tire inflator is about 2 inches wide and 6 inches high (rough estimate). This is the second one I’ve purchased—the first lasted over five years with heavy use before the cord gave out, which was likely my fault. It functions exactly as it should and helps me quickly get tires to the desired PSI. If a tire is flat, it will take some time to fully inflate, and you need to ensure the vent isn’t blocked to prevent overheating. The accuracy is spot-on; I’ve double-checked with another device, and it’s dead on. It’s a good value for the money, long-lasting, and easy to store in your car. It plugs into your car’s adapter (formerly the cigarette lighter). Pros: Slim, compact, and easy to store Accurate PSI readings Durable and long-lasting Good value for the price Cons: Can take time to inflate completely flat tires Must ensure proper ventilation during use Conclusion: Overall, this tire inflator is reliable, accurate, and compact. It’s a practical tool for anyone needing a convenient way to maintain tire pressure on the go.
