ENGWEBike Pump with Presta & Schrader Valves, 100 PSI Bicycle Pump for Electric Bike Tire Pump Mini Bike Air Pump Handheld Portable Bike Pump Universal Small High Pressure Ball Needle Accessories

I haven't had to use it but I did try it on my tire for a test run it seemed to fit with ease, and pumped air, it says its rated for 80 to 100 psi. I like it it looks slick on my bike too. I give it a 5 out of 5.

Over the past 35 years, I had about 3 mini bike pumps ranging from $10 - $25. I like this one the best. It is very small (fits in my large seat pack), water-resistant (rubber caps and gaskets), and the easiest to get higher pressure. I like the reversible hose for either Presta or Schrader valves but be careful not to cross thread while screwing onto your innertube. At < $6 including free shipping, it is the least expensive one I have owned. I liked it so much, I got one for my wife's bike. The pump barrels are made of an alloy, not plastic (not too big of a positive). For a 26" x 1.95 mountain bike tire, it took 100 pumps to get to 18 psi, 200 pumps to get to 28 psi, and 300 pumps to get to 38 psi. This is all I need if I am on the trail or away on vacation. I don't typically refill my tire until it gets down to around 25 psi. My previous best mini pump (Chubbie) with telescoping pump action got to 38 psi in half the pumps (i.e. 150), but the last 50 pumps were very hard, and I was pretty much maxed out. Where this mini pump wasn't that hard to pump to 38 psi, and therefore, would be my best bet if I wanted higher psi for a road bike tire or any other tire. The materials are of good quality. I expect this pump to last for many years especially since I will only use it once in a while for emergencies.

This is very durable. No problems at all.

Slightly complicated to use but it may be that I was just infirmary with presto valves. My tires take 100psi and it takes foreveerrr to get it pumped. The price you pay for portability I assume. Fulfills the need though.

Update 6/27/23I've given it 1 more star, seller did offer a refund, but I declined since mine did workAs I stated, it's well made - good as backup if needed -Original post:It's reasonably madeI have a fat tire ebike with a max inflation of 20psiI run 15+/- by other guages (milton, Jaco)I read 16psi on both of those and 10psi on this (3 times in a row)I'll keep this as it's compact with a gauge, but mine isn't accurate by any measuregreg

My lawnmower tire went flat and in no time this had me mowing

Doesn't work out of the box. You need additional pipe to make it work. That is not clearly mentioned in the description. Non of the valve provided with it fits directly to the pump. No clear documentation how to use it.Update: after further research I could figure out the pipe is include on the other side of the pump. However, it was really difficult to understand. Changing my review from 1 to 4. Could give 5 if they have given the proper documentation for this.Otherwise the product is really great at this price and works flawlessly once you sorted out the pipe issue.

This mini pump is really convenient, and gets the job done. A lot of [negative] reviewers seem to have ignored step #2 on the "Operation tutorial" photo of the product, so they're not realizing that the cable is actually stored inside of the pump. Just twist and pull it out for the corresponding Schrader or Presta valves. I doubt you'll find a better pump at this price point.
