  • Great pump
Returned first one since it wouldn’t charge. The replacement is great, it will reflate a tire three times before needing to be recharged . The Case is nice, helpful and durable. Not noisy and doesn’t heat up like others I’ve tried. Wish it was a bit faster but, can’t have it all.

  • Nice little pumper!
Portability is great with this air pump. Fits in the car, on a shelf it’s great! Very user friendly and comes with nice power. This pump does have auto shut off once the desired PSI has been completed. This little pump is of good value for the price and performance that it provides. I am on the fence with the charging and battery longevity. Over-all a good product and I would recommend. ... show more

  • Very nice unit!
I was looking for a cordless air pump for my bike, car, or what else you need a air pump for. This was a very pleasant surprise it was well thought out efficient look good and did the job. I was impressed. Another surprise was an actual instruction manual that you could hold in your hand and read which seems to be a loss accessory in many things that you buy. Definitely worth the money. ... show more

  • Does The Trick - Battery Ok.
This is a decent quality air compressor for an emergency when you have no other option. It performs well but the battery is just enough to increase four tires by about six pounds each before it needs to be recharged. It is simple to use. It is nice that the attachments are all on it. It is very light to carry and move around. It is very versatile for many air operations from balls to tires. You can use it just about anywhere. It has some power but can be slow as you get to the higher pressures. ... show more

  • Fast and quieter than most
Pros: 1. The air hose is longer than most, 20 inches. Better for large tires if the valve stem is on top. 2. Nice accessories: Case, metal air chuck quick connecter. On board needle valve, and pool toy adapters. Good charging cord. Good instructions. 3. Faster and quieter than most. 30 seconds from 33psi to 37psi. 4. Easy to use. Preset settings for, Car, Bike, ball and is adjustable to your specific needs with automatic shot off at the desired pressure. 5. Quality seems to be very good. Not flimsy plastic, very solid. 6. The light is bright and lights a large area. 7. The display can be seen even in sun light. 8. Good price point especially when on sale. Cons: 1. Can't be used while charging. 2. Air chuck attachment doesn't swivel. ... show more

  • Does exactly what they say it does. Most perfect tire inflator I have ever seen.
It comes with everything you need. The easiest hook up to a tire I’ve ever seen. All adapters are nice, but you should never need them. It is very powerful.

  • This air compressor has changed my life!
I didn't send a photo because the machine looks like its photo. I'm not exaggerating when I say this has changed my life! I have a late model MB with those automatic tire readings & if one tire is out of balance even by 1 lb psi the idiot light comes on & its a major distraction. With seasonal changes, this happens several times a year. There are fewer and fewer "free" air pumps at service stations; the one I had to use last week was a credit card pump & charged $.3.75 for air. It also had a small electronic display, no "dings" as the air went through, and was silent so you couldn't tell when it had reached the required amount. As a "mature" woman, I also feel quite vulnerable putting air in tires, often with a bunch of unemployed males hanging around the service stations. They're probably no threat but I don't feel safe. Finally in desperation, I broke down & purchased this pump because of its outstanding reviews. Let me say, the reviews don't lie! It charges quickly, less than 30 min. It can fill 8 vehicle tires & 2 bicycles with one charge. It has a clamp to hold the hose onto the tire stem (FABULOUS!). It reads the psi as it pumps & stops on the exact pressure. I double checked the pressure with a hand gauge & it's on the nose. It's light, very portable, perfect to keep in the car trunk, and directions are clear & simple. I could use it for other inflation needs--it has various nozzles clamped to the back--but that's not my need. I can fix my tire pressure in the safety of my garage at any time! I love this appliance, as you can tell! I'm so pleased with this I purchased one for each of my siblings & talked my cousin into getting one. It's not the "cheapest" on the market but the price is fair and I'm thrilled with it. ... show more

  • Compact air compressor.
Rechargeable, small, and lightweight. Works well but I would give it a few minutes to cool down between fills if you’re doing all the tires.
