Tire Inflator Portable Air Compressor for Car Tire, Cordless & Strong Power, Air Pump for Car Tires with 6000mAh Battery, Fast inflate 150PSI, Tire Pump with LED Light for Car Bike Motor Ball

I just bought this little battery powered compressor for my trailer break down kit.This little compressor is fantastic. It is light, remarkably small, and powerful. It was well packaged and delivered by Amazon the next day. I saw this on a recommended link in Road and Track and decided to give it a try. On sale for $42, I figured I didn’t have much to lose.The instructions were clear and easy to understand. I charged it up with the included USB connector, screwed in the hose, and I was ready to go.I wanted to top off my trailer tires before an upcoming trip, and they need 80 PSI. This would be a good test. Hooking it up with the locking connector to the stem of the tire was easy. Turning it on, it showed me the current tire pressure on the digital display. I was at 60 PSI. Using the plus button, I turned it up to 80 PSI and hit the start button. The compressor came right on and I could see the pressure increase as it ran. I sat it on the floor and let it run. The large display was easy to read from across the garage. It took about 5 minutes to reach 80, but it got there! It ran steady throughout, and there was no sign of laboring near the end. It gets hot, and it is loud. At the set pressure, it shut off automatically.I repeated the process on the other tire, and it work just as well. In 10 minutes of running, it used about 3/4 of the battery charge. After unhooking, I put the compressor back on the charger. Being careful around the orange connector, it was pretty hot. After reaching a full charge, I packaged it up. Putting it away with the instructions, adapter tips, charger cable, it all fit in its own carrying bag.I really like this little device. It even has a small LED light that could be used in a pinch. Running off an internal battery, it is so much easier than using a compressor with a power cord. It goes through the battery pretty quickly, but should have no problem re-inflating a flat tire. This and a can of Fix-A-Flat might be all that is needed. It is a nice small addition to my breakdown kit.

I’ve using this devise for a couple months now. I have no complaints. It fast without leakage. It’s super easy to use. Great quality and size. It fits literally anywhere . I’ve used many other brands before and this one definitely stands out. You won’t regret it.

I really wanted to like this little gadget. Reasonable price, all the features I wanted, compact size. I bought one for myself and another for my Civil Air Patrol squadron. But the first thing I discovered about it was that you cannot just leave it permanently on the charger. For reasons I can't identify, after a day or two on the charger, when you disconnect the charger, the battery is dead and the unit will not power up. If you charge it again and take it off the charger immediately after it is fully charged, then it will work. The same thing happened with the squadron inflator. On the plus side, once charged, the battery will hold its charge for a good long time. That was inconvenient but satisfactory for a while. Then yesterday, I tried to charge a tire on my vehicle to the required 38 pounds of pressure, so I set the target pressure display to 38 psi. When I connected it to the tire, which I had independently measured to be at 34 psi, it began to inflate the tire, but soon registered 51 psi and stopped. I used my tire pressure gauge to check the pressure, and it was still at 34 psi. I tried ramping up the target pressure to the mid-50s psi, but the same thing happened.Edit: I found the factory manual and looked at the trouble-shooting section. Sure enough, the problem I encountered was a result of pushing the chuck all the way onto the tire valve, which fooled the device into thinking the pressure was too high. When I slid the chuck only part way onto the valve, it inflated normally. I'm leaving the rating at three stars because of the finicky charge behavior and the finicky chuck adjustment. I prefer to leave devices I don't use all the time on the charging cable permanently, so that I'm assured they are fully charged when I need them, and I cannot do that with this device.Second edit: of the two identical chargers I purchased, one (this one, that I purchased for my Civil Air Patrol Squadron) died after 16 months of light use. My personal inflator, which receives very infrequent use, is still working, but one out of two pooping out after a mere 16 months is just not acceptable. Hence the one-star review. I suppose you get what you pay for.

Nice little pump, does the job, and pretty quickly too. It does make a fairly loud BRRRRT but that's what air compressors do.First use was to inflate four 205/65/R15 tires from ~20 psi to 35 psi, and this was done in about 12 minutes total, using about half the charge it still had on it, fresh out of the box.After recharging to full, I then inflated four 225/70/R15 pickup truck tires from ~25 psi to 35 psi. This took longer per tire, because of the larger air volume, which is probably why the manual says it's not recommended for truck tires. I wouldn't try it on a much bigger tire than a 225, the pump and hose got pretty hot and I needed to let it cool down after doing two of the bigger tires. There is a thermal cut-off built in, which did not reach the threshold temp, but I opted to be cautious.Nitpicks: The air hose could be longer, but it hasn't been a huge issue. (Other reviews have mentioned a longer replacement hose and I may yet invest in one, just for convenience of positioning the pump on the ground while in use.)Also, the little micro-manual is laid out in littler micro-micro-print, why do they do this? Ten more square inches of paper is too much? and 8 pt Arial letters are cheap too.But overall I am VERY pleased with this compact compressor. Convenient size, easy to operate, and feels solidly made. The big question as always: how long will it last? ... especially for a battery powered device that sees infrequent use. If and when it fails, I will update this review.

This is a great addition to my tool kits. My bike tires use presta valves and there was no specific description in Amazon if this included the adaptor or not. One photo shows it does, and another photo doesn't. I took a leap and happy that it did. I would suggest lightly screwing the adaptor first into the tire's presta valve before fitting the hose and then locking the handle in place. I held the inflator at an angle to minimize any horizontal pressure from the hose and risk bending the presta. The device is pretty solid and intuitive to use, and will have to see how long this would last. I haven't used it for car tires or put it in a real stress. Operationally it is loud like a busy street at 75-77dB. The default PSI setting helps but seems very permanent. The bike tire default is 30 PSI and I use 25, so it is a manual change every time you use it on a tire. The package includes a nice black pouch to keep all the accessories together.

Good price, easy to use. Lasts a long time on one charge. So glad I bought this.

This has turned out to be a very useful little unit. Have pumped up everything from the wheel on the wheelbarrow to the kids bikes. It has pre set functions too (if your pumping a ball, bike tyre, car tyre, etc), so even persons such as myself, are able to use without over inflating. Comes with everything (assorted ends, charging cable, etc).

I ordered a RYSEAB Portable Tire Inflator through Amazon last August. I'm downgrading my review temporarily, as it stopped working after a few months and I had only used it twice on my car tires. I had emailed to its customer support and hope for a resolution.Update on 22 April 2023: Upgraded it to 3 stars temporarily. Customer service has kept in touch with me with prompt reply and refund. They are unable to send me a new replacement due to territorial issues. As they have rectified the issues in its new model, I just used the refund money to order another inflator. I would say its customer service is prompt and responsive to my satisfaction so far. I'm now looking forward to the arrival of the new inflator.Update on 2 May 2023: Restored the rating to 5 stars, as I have received and used it to inflate my car tyres effortlessly. Hope it can last this time.

This is great for on-the-go pump. You can use it for anything that required air. They have attachments came with this pump. I am using for my car tires, just set the PSI and it will stop when reach that PSI.I used for air 6 tires and still have 1 - 2 bars battery left. Might get more out of it, all depends how long you use it.
