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

Needed to replace my old inflator as died after decades. Wanted same type that worked off car not battery, this one works great, half the size as old one and more powerful. Fast and powerfl with easy controls, couldn't be happier, love carrying case for trunk!!! Awesome value!!!

Great little pump for the cost. It is not as fast as advertised, but not slow either. Very compact and the functionality is great. Set your pressure on the display and it goes until done. Easy to set. EVERY car or ATV should have one!

Excellent little device. Simply to use - works quickly and efficient. Small word of warning that this type of device will most likely not last for ever, it probably can only do a couple of hundred full tire inflations and then will fail - but for most folks that will last them years and years. Remember to keep it in the car - and not the kitchen draw!

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.

This inflator has worked perfectly for me this last week or so, since buying it. Some of my tires have lost air pressure regularly because of the continual sub-freezing temperatures. So I've used this frequently. The build quality is solid throughout. I especially appreciate how sturdy the valve is, and how smoothly it locks in. Also, the power cord is a heavier gauge than a neighbor's inflator that I borrowed. The hose and its connections are strong. I'm very glad I bought this more robust inflator, than the rechargeable battery ones I researched. I use this from my car's power, and occasionally also a smallish 12v power station I have. The digital readout is clear. I like that both the target pressure and current pressure is shown. The current pressure updates every 0.5 PSI. That lets me inflate to somewhat below my ideal standard, to save time if I have to drive a short distance but right away. The speed of inflation seems good, similar to the "conservative" statistics mentioned by some other reviewers. I've tested inflation pressure a few times with a quality bike tire pressure gauge. This inflator tends to over-inflate by about 6-8%, and consistently. About 3psi when tires are inflated to 40psi. So it seems very stable and predictable. The price was very reasonable, for what I feel is a superb product. I highly recommend this.

Intuitive and easy to use. I bought the ROCGORLD R8 Tire Inflator Portable Air Compressor almost four months ago and didn't have a need to use/test it until now (late March 2026). My VW Jetta 2011 Sportswagen TDI's dashboard indicated low tire pressure. At home, I got out the ROCGORLD R8 inflator for the first time and didn't see that the instructions had dropped to the floor on the passenger side. It was easy enough to figure out how to operate but there were two things to be aware of: 1) the car must be turned on (I had the engine running, but maybe it just needed to be power on) and 2) the "M" button stands for "Mode" and if you're in the US it should be set to PSI. I didn't realize this until I found the instructions after inflating and I had way overinflated because the Mode was on a German setting. So I let air out and redid all four tires. The ROCGORLD R8 gives present tire pressure and target tire pressure readings simultaneously, and setting target reading is just a touch on the + or - button. It turns off automatically once target pressure is achieved. And by the way, from my dash 12v outlet I could comfortably reach all four tires. I feel so much more confident now about being out and about, especially on a long trip, knowing I can easily fill up my tires myself if it is low and it will be accurate, no guessing. Also, the kit includes three different tips so you can fill your bicycle tires or volleyball, etc.

So glad I bought this! It works quickly and easily, and needs no time to charge up! The cord is long enough to reach all four tires, and the design is compact so that it stores away nicely in my car! Great product!

This little air compressor is great. Compact, nice digital read out, great little carry case, works great. Plug it in to 12v , set the psi and it does its job. Very good product for the price.

Très bien
