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

So far this has worked as expected. It captures the pressure and refills my tires to the correct level. The case of incomes with is convenient for storage. Overall for the price and convenience I think it is definitely worth it compared to trying to find a tire pump at a gas station or mechanic.

Great product. Easy to use, with clear instructions. Inflates quickly to whatever pressure you set it to. Compact size & comes in convenient zippered case. The cord plugs into your lighter and is long enough for front & rear tire. Pass thru car to reach the other two tires. Comes with accessories to use on bikes and basketballs, etc.

I’ve had this for 10 months, and it still is going strong.I find it convenient and simple to top up tire pressures, no need to search for a gas station with a compressed air machine, and much easier to use than the manual gauges they often haveThe display is large, just enter the required pressure, the powerful air flow fills until the pressure is reached and automatically stopsDefinitely worth having to keep in your trunk. I had to use it yesterday and was so happy it was there

The auto-stop feature and memory function are great for convenience, and the emergency light modes are a nice bonus for night use. The build quality feels strong, and the included accessories like the carrying bag and different valve adapters are useful.My only minor complaint is that it doesn’t include a built-in battery or AC adapter option, so you’re limited to using a 12V car outlet. It would be even better with a rechargeable version or a bit longer hose for added reach.Still, for the price and performance, this inflator is a great buy. Would definitely recommend it!

Exactly what I was looking for. I'm able to set for the PSI I'm targeting and it will stop when reached. Quick and fairly quiet, nice and compact. Digital and easy to read. Love it!

Wow! I have had a version of a portable car compressor before, but this one is the best! It is very quick, simple, easy to connect, and easy to read. What more can I say? All four tires needed air. I was done in about 10 minutes, including unboxing it, reading instructions, and getting the air in. My old one was barely putting out any air, and it was taking 10 minutes per pound. This one felt like "instant". I strongly recommend it. It is also an excellent gift for family members who have their own cars.During COVID, before my other brand slowed down, I aired up all four tires while in the parking lot waiting for a take-out order! It also really beats having to go to a gas station and drop in lots of quarters.I am a normal person with no special car fixing skills or extra strength! This is very easy to use.

I finally replaced the Craftsman automotive air pump that I bought in Kmart long before it went out of business. That air pump was primitive to today's standards having a small and difficult to read gage with no automatic shut off and a tire valve connector that was hard to get on and off. After trying out the new Rocgorld pump I must say I really don't miss the old one at all because the new one is so much easier to use. There are two large digital pressure gages, one showing the tire's pressure, and the other showing the automatic shutoff pressure. The tire valve connector is quick and easy to connect to the tire valve, and the controls are very intuitive. Like the craftsman unit, the Rocgorld is powered off the car battery via a cigarette lighter plug adapter. That may seem inconvenient, but considering that I live in South Florida where flashlight batteries left in a hot car have an extraordinarily short lifetime, the car battery powered pumps are a much better idea. I looked at many but this one really seemed to earn the Amazon Choice award!Update: I had a flat... the first time I used the pump it kept changing the mode (unit of pressure) but the next 4 times I used it before finally getting the tire fixed it worked perfectly. It pumped up my Jetta 16 inch tire from completely flat in 5-6 minutes. I'll keep it!

I've used it once and it performed well. It aired up a tire fairly quickly. Compact in size and has the clamp on hose attachment which is easier to use than the screw on type, in my opinion.
