    5.0 out of 5 stars The Real Deal

    This pump works really well, perfect to have around the house. Instructions are clear and it’s easy to operate. Inflated my car’s tire from 20 PSI to 35 PSI in about 3 minutes. The noise is what you’d expect from a pump, it’s not overly loud. Battery can be drained pretty quickly but it does not take long to charge so it hasn’t been a problem for me. Highly recommend!

    Realty small and yet works well to fill tire to set pressure. Good choice for motorcyclists but too heavy for bicycles to carry on trips. Easy to connect with provided air hose.

    I brought this to use for my motorcycle. It also worked for my car too just burned the battery quicker but great for my motorcycle. I was able to put air in my tires and charge my phone.

    This tire inflator is the first I have owned and I am wondering how I lived without this thing. It is amazing. I just started motorcycling and I use it all the time, easy to use, easy to read has a preset tire pressure capability so you set it and it inflates to the correct pressure. I love this and cannot it is so inexpesive. We bought 2 for our Motorcycles and now I want one for each car.

    4.0 out of 5 stars Good value but No presta adapter
    Reviewed in the United States on August 11, 2024
    Main reason I'm giving this four stars instead of five, is no Presta adapter. Main reason I chose this one was the description said it had a presta adapter and I bought it to inflate the tires on my two bikes that both have presta stems. Either the description if wrong or they forgot to incude it, the other advertised adapters were included.

    Forgunately I have a presta to shraeder adapter in the saddle bags of both my bikes for the strems and just used those.

    It has suggested presets but those are WAY off, so make sure you know your tire pressure. For a bike it's something like 45 PSI and my one bike is 65 and the other is 85. I just manually changed it and it worked fine.

    It charges really fast but battery life isn't that great. Works great for adding air on a low tire, but wouldn't use it for commercial purposes. Both tires were totally flat on my one bike I haven't riden in about a year, and my bike I use every day needed about 15 PSI in both tires and the battery indicated was low after just that. Also took a while to fill the two flat bike tires, so it would probably take a good ten minutes to fill a flat car tire.

    Good value for the money. I looked at similar ones that were quite a bit more, and this was the most reasonably priced one that had good ratings.

    The other minor complaint I have is the the insutruction manual type is very small, and unless you are a twenty year old with perfect vision, you'll have troube reading it. It's pretty common sense to use though and there are plenty of videos on how to use it online, so that's not a huge deal.

    If it had the presta adapter included, I'd probably be giving this a five

    5.0 out of 5 stars Great addition to my gear bag.

    I got this product to replace several tools for checking and inflating my motorcycle tires. With this I simply set the pressure I want, attach to the tire stem, and if pressure is needed hit the ON button. The tire stem attachment works quite well without any loss of air going on nor coming off.
    I charged it up right out of the box, as the battery indicator was Yellow. Once fully charged I added 7lbs of air to my motorcycle's front tire, 2lbs to the rear, and 7lbs to each of my wife's Nissan Maxima's tires. As expected the hose gets a little hot and I did take a break between filling the front and rear tires on the Maxima. The motorcycle tires filled quite quickly, the car tires took a little longer, but it was just a few minutes each for the car tires. Now it's a wait and see how long the battery life is.
    I considered the Lexin P5, but I'm only using the pump for my motorcycle tires mostly and I didn't need the bigger battery. I figured for the most part wherever I can charge the pump at, I can also charge, let's say, my phone too, so I don't need a big battery to charge other devices.
    I'm very happy with my purchase so far. I bought the brand because it's recommended and sold by a very good motorcycle merchandize supplier. Prime has quicker delivery.

    What a design. Simplicity is what makes life easier. The architecture and engineering of this is a blessing for those that are uncomfortable with technology.
    It could not be any easier to use. The designers and craftsmen should be given a medal for their final product.
    With winter fast approaching this is a must have. My tires were down 3-6 lbs. in less that five minutes I was able to top off each tire. Had I known earlier, well you know the story.

    5.0 out of 5 stars Perfect small pump
    Reviewed in the United States on June 6, 2024
    I used to have heavy 5 gallon tank pump in my garage. Now I have this little portable pump. It is so light I can carry to anywhere. Of course it’s not as powerful as my stationary pump, but for routine maintenance it is enough to top up four tires. My big stationary pump ended up not being used anymore because this little guy does every routine pump. I even brought it to work and pumped up numerous work vehicles. Only then I need to charge the battery often. Stationary big pump works much faster if you have a fleet to deal with.

    In summary, this portable pump is good enough for all personal vehicle maintenance. Every car should have one in its trunk, especially EV without spare tire
