LILTSDRAE Bike Pump Mini Tire Inflator Portable Air Compressor 150PSI Cordless Electric Bicycle Air Pump, Auto Shut-Off with Presta and Schrader Valve Smart Electric Pump

I bought this product to put air in my bicycles tires. Unfortunately, it refuses to inflate past 35 PSI. These tires can take 60 PSI, but it simply will not pump that much air. It appears to work properly; it just stops at about 33-35 PSI. In fact, when it hits its limit, the PSI number starts going backwards. Thinking perhaps the first tires value might be defective, I tried it on the other tire, but got the same results. It seems unlikely that BOTH values are defective, especially since the bike is almost brand new. In any case, I tried leaving the pump running on each tire until the battery ran out, and it still would not inflate past 35 PSI. I havent been able to find a website for the company that makes and sells this product (so I could seek help from its customer service department). I hate writing a negative review until Ive given the company a chance to make things right, but it seems my only option is to leave this review in the hope that someone from the company will reach out to me to help resolve this problem. If they do, I will change my rating.

Only had this little guy for a short time but works awesome. Only use it for my bike with the presta adapter and it saves me a ton of pumping and hassle. It is surprisingly not a really loud or annoying sounding motor. I carry it right on my bike strapped in a cargo cage. Some people reviewed that they put it in their bottle holder but I dont know what kind of bottle holder they might have because it is too small for a standard bike bottle holder and will fall out unless you have extra straps or wrap it in something.

Just flat out I didn’t like much about it , I’m sure it works fine but it didn’t meet my expectations!

I needed to inflate some seriously deflated bike tires and my mini pump wasn’t going to cut it. I ordered this pump, figuring I could also keep it for my car tires. It works really well, inflates quickly, and is fairly intuitive to use. The display is very helpful to know how much air you’ve added or need to add, and at what pressure. Highly recommend!

Update: received a full refund from the seller for this error, and making this a 5 star review as he deserves. Battery may be weaker and with less capacity as advertised but this thing works like a monster for our cycling and electric scooter needs. Advertised 4000mAh battery; manual says 2000mAh battery. No lock for valve makes it harder to use.

I bought this to maintain my air suspension on my Harley, so I don’t know how long it would take to fill a tire. It works better than I had hoped for my needs.

I love this bike pump. I charge it like I do my phone and it is so easy to use and keep with me while Im out riding. It also fills the tires on my bike really fast.

Fills bike tire to desired psi in good time. Unit gets pretty warm so best to let it cool. Psi gague appears to be accurate. Like other reviews, manual is generally terrible but gets the point across. Have not used it to fill anything else except for a presta valve on a mountain bike. Would suggest - a good buy.

i like this product, is always a reliable and quick to inflate tires. I was expecting something with less weight so easy to maneuver it. Overall im satisfied, but will i purchase this again.... probably not

Never underestimate small things. I was speculating whether this thing would work or not. The best money I ever spent all for my tires are low between four and 8 pounds this thing filled up all four tires 38 psi in no time did not use one bar on battery life. I recommend this device For everyone.
