OlarHike Tire Inflator Portable Air Compressor,Dual Power-3*2000mAh &12V DC

It arrived at 75% charge, which is normal for products with lithium it prevents battery damage (you should try to keep lithium batteries between 30-80% charged) . I wasn't aware it has a light built in, a usb port for charging things like a phone, and it has pictures of things you want to inflate and you can swap between them. It will show a picture of a car and choosing it goes to 35psi, switch to motorcycle 45, switch to bicycle and it will go to 75, ball 8 which is convenient you don't have to keep changing the psi for what you want to inflate. More interesting is that it lets you adjust them, for example I changed the car to 34 psi and from then on whenever I chose car it went to 34 so it remembers your settings. What I mean by remaining charge seems off in title is that it came at 3 of 4 bars charged. I used it to inflate my car tire from 24 psi to 35 and another tire from 30 to 35 and the battery meter went to 1 bar. I was thinking the battery doesn't seem to last long, I put it on the charger and it took over 2 hours to charge from 1 bar to 2... I was thinking it's going to be a 6 hour charging experience to go to full but then 15 minutes later went to 3 bars when I stopped charging it. I then inflated my remaining 2 tires from 30psi to 35psi along with my snowblower tires (from 0 to 8psi) and it's still at 3 bars which doesn't make sense to me it had just changed to 3 bars just a small amount of use should've dropped it to 2 bars. So, the remaining charge seems wonky but the device was much better than I expected. I came from a Ryobi hand held inflator that took my tool batteries and cost 3x more than this. The Ryobi inflated a little faster (with a caveat) but didn't have a preset psi it would stop at, didn't have a light, nor usb charger, nor could plug into my cigarette lighter, nor had multiple settings (car, motorcycle, bike, ball), nor was display as easy to read. There's pretty much nothing about it that is better than this one except it being a little faster with the caveat after 10 minutes of use that Ryobi inflator would start smoking and I'd have to wait for it to cool to continue which would make it slower than this one if you needed to use it for more than topping off. After a year the Ryobi was making more and more clinking noise until the insides broke and failed. Hence why I got this one. This one runs much smoother, I particularly didn't notice heat build-up after 15 minutes of use which I was specifically looking for after my Ryobi would smoke, it's more compact, and the value is a complete surprise.

Overall Performance: This portable tire inflator has been a complete game-changer for our family. We previously bought a cheaper Walmart brand air pump for our smaller vehicle, but it took forever to fill a single tire. In comparison, this unit airs up tires remarkably fast! It easily inflates our larger SUV (a Honda Pilot) with zero struggle, and it still holds plenty of battery charge afterward. In fact, it easily handles all four tires on a single charge. ​Features & Convenience: The digital display interface is crisp, clear, and very easy to read. It takes the guesswork out of checking pressure levels, which gives great peace of mind before long road trips. ​Included Attachments & Limitations (The One Drawback): It comes with handy adapter needles for sports balls, bicycle tires, and standard pool inflatables/tubes. However, the main downside is that it lacks a high-volume adapter for inflatable air mattresses/air beds. If you are going camping or hosting guests and hope to use this for an air bed, it won't work out of the box. ​Final Verdict: Despite the lack of an air mattress attachment, its main job—inflating vehicle tires quickly and reliably—is top-notch. We love it so much that we plan on replacing our slow, frustrating small-car pump with a second one of these. It was was easy to use and is still a compact size. Highly recommended!

I've been really impressed with this tire inflator. The display is bright, easy to read, and makes it simple to keep an eye on the pressure while filling tires. It seals well to the valve stem and doesn't leak air while it's running, which is something I've had issues with on cheaper inflators. It also fills the tires on my truck surprisingly quickly. The biggest advantage, though, is the portability. Not having to deal with a cigarette lighter plug is a huge convenience. I can take it wherever I need it without having to leave doors open or run cords through the vehicle, which is especially nice when it's extremely hot or freezing outside. Overall, it's easy to use, works exactly as advertised, and has made checking and topping off my tires much more convenient. I'd definitely recommend it to keep in your vehicle.

I got this as a way to teach myself how to maintain certain things on my vehicle rather than bothering my mechanic every time something small happens. Namely, every time where I live there's a cold snap, my TPMS light goes off. Irritating beyond belief, and isn't good for tread life or fuel efficency. Mechanic suggested I get a battery operated tire inflator to take care of it. That's where this comes in. First a bit of background: I got the 6000mAh variant of this inflator. My car's tires are rated for 33psi, but for my use I fill it to about 35psi. It comes with a few attachments, mostly for different types of valves, for say bicycle tires, or even sports balls. For filling a standard vehicle's tires, you can just use the hose itself with no attachments. The hose attachment is not very long, which can make using it a "set it down next to the tire and let it do its thing" affair only. Trying to hold onto it is uncomfortable, as it's well, quite literally as thick as a brick. However, not so heavy that you cannot travel with it. As part of an emergency kit in a car, it'll do just fine, but more on that later. The one thing I do appreciate though is that there is a rubber safety guard for after you are finished and need to disconnect the hose. This portion of the hose gets really HOT after use and the rubber guard will prevent you from burning your fingers/hands. The inflator itself when turned on, has a few presets to choose from, but you can also fine tune the psi setting on the inflator by 0.5psi increments if you want to set a custom. These presets also illustrate with icons what you typically use them for. My initial use had all four tires sitting at around 30-32psi. I set the hose over the valve of the tires and locked it with the lever. At this point the inflator shows what the current psi is, and it's target psi you set. Yes, effectively this acts as a pressure gauge, but I would still make sure you test after with a secondary dedicated gauge to ensure full accuracy. Once a target is set, you set it to start. It will, as most of them do, make a ton of noise, so do not expect to be discreet when using this. It will continue to fill, until its actual pressure meets target. The inflator will then self turn off completely upon reaching the target. You can turn it back on and verify the target while still connected, or use a secondary gauge to test. My test yielded only an error of about 0.2psi, which is pretty accurate. It took approximately 2 minutes to fill from 30-35psi on one tire. Setting up the other tires when I had learned how to use it initially went much faster and easier. All tires were filled to near or slightly above 35psi within 10 minutes. Unfortunately it does earn a mark off for one thing: After I was done, its internal battery had registered a halfway drain from full charge. I am not sure if this is atypical of these types of inflators, but if you have a completely flat tire what this tells me is it will only be good for one completely flat tire off of the internal battery and then you will need to either charge it again via USB-C, or using the car adapter. Even then, using the car adapter might not be enough to charge it fast enough before the internal battery completely drains and shuts off prematurely. Although the 6000mAh is fine for my personal uses, for someone else it may not be enough. I myself cannot help but feel like I could have actually benefitted from going with a higher capacity model. It would make it a better standout in an emergency kit, which is a standout reason someone may buy this. Overall, very happy with it, would recommend it, especially since it is relatively inexpensive, fast, and accurate, if you just need to top off some pressure on something. But watch what you use it for and how long. If you need a large amount of inflation time, get the higher capacity battery models.

To say I'm impressed with this product is an understatement. This thing ROCKS! When I first got it I plugged it into my 2.0 USB port on my computer with the charging cable they provided. The pump had 2 of 4 bars already lit, so I'm going to say it was already at 50% charge. It took 3.5 hours to charge it completely. But I did buy the one with the larger battery, the 9,000 mAh, so I knew it would take longer. I opted for the larger battery power because I have two cars, a bicycle and a boat trailer. I've been using my large compressor, but getting it out and laying out cords and hoses just to top off a tire was such a hassle. This pump eliminates that. I decided to let some air out of my spare and then test the pump on it, since it was easy to get to. My starting pressure was 29.5 and my target pressure was 40 pounds. It took exactly 60 seconds to pump it to 40 pounds and shut off. Excellent! It was quick, but kind of loud. About as loud as the old portable kinds you had to plug into the cigarette lighter socket and took forever to air the tire up. The pump shut off exactly where I set it for. The display is big and easy to see and understand. This pump has some heft to it and feels substantial in my hands, so I think it should last a while. Overall I'm very happy with this portable air pump!

This OlarHike portable air compressor is great! It is pretty fast, and easy to use. I ordered the 7500 pro capacity because I was worried about battery capacity, but I topped off 12 car tires and only used 1 bar of power. I used USB-C to recharge the pump. I really like how it turns itself off when it gets to the selected pressure. Measures pressure in half pound increments. Not quiet, but not as loud as my old 12 volt (cigarette lighter) Slime compressor. It comes with a standard presta valve adapter for bike tires.

Am happy with this purchase. Used it on kiddos bikes, balls and car. Very power and quick to inflate all that was needed to come back to life. It shuts off automatically when it is done. Portable, not much space is needed. Love it how its versatility, convenient. Quality it holds pretty well comparing to the old one that plugs into the cigarette lighter ONLY. It packs lots of power, has not heated like the old one and most of all the noise from it is much lesser than the old one. Made to keep.

In general seems to be a pretty good solid working product. I charged it full before using it. I have to Canondale hybrid bikes with Maxx DTR-1 tires which state 65 psi max. I set the inflator to shut off at 60 psi. All 4 tires had air, maybe at 35 psi since we have not used them for approx 6 months. Proceeded to inflate all 4 to 60 psi and it auto shuts off. Unit handled itself well but definitely the full charge went down to about 20% (description states much more than 4 inflations which is what I barely got). Definitely not a good sign battery wise. I put it to charge immediately as a precaution. That is the main reason I only gave 9 stars. Otherwise very handy and portable. It comes with a storage puch.Hose is long enough, has other features such as flash light and USB- A as well as USB-C to charge other items.
