WoowindBP188 Bike Pump, The Pro Electric Bicycle Pump Tire Inflator Portable Air Compressor with Schrader, Presta and Dunlop Valve Adapters - 120~150PSI Options

Recently purchased this Woowind inflator. Handy!!!! Easy to use! Compact! high quality durable and can inflate just about anything! Very pleased with the ease of use.. right out of the box.. within 15 minutes had pumped four bike tires using the custom and auto settings. The Led light display is large enough to read without my glasses and the flashlight part worked well too. It's a little heavy, but I'm sure that is because this thing feels like a high quality tool that I expect I will use for many years. This saves me trips to the bike shop or just trying to guess the inflation when using random air hoses or I have to deflate a little on muddy or sandy trails. Good tires are so expensive and no one likes a flat. Consider this as insurance AND an investment!

Works at advertise, but one’s hot. It didn’t like my fat hands lol

Found this to be a piece of junk. I have a road bike with presta valves. I’ve inflated tires with presta valves before so I know how they work. I’m 100% positive I used the presta valve attachment and that I used this product correctly. I even read the entire manual and watched several YouTube videos because I thought I was crazy during this process.For reference, both of my bike tires were completely flat. Started with my back tire. Screwed the attachment and hose on tightly, ran the machine and the tire began filling. I had it set to 110psi. After a while the tire became rock solid but my machine still only read 60psi. I switched it to bars to be sure and continued filling a bit longer. The goal was 8 bar. It still only read 4.1 bar and never wavered. Then the device ran out of battery and died (after only a few minutes of use, and 1 tire in).Charged it back up.Back tire seemed good enough despite the off reading so I moved on to the front. Tightly attached it to that presta valve, set the goal to 110psi… it ran for about 2 seconds before saying “done” and automatically stopped. I unattached, then reattached very tightly and the same thing happened again (tire still completely flat). Because it automatically cuts off when it reaches it goal pressure, there was no way to make it keep going even though it mistook a total flat for 110psi.Almost forgot to mention. The device gets SO hot. I saw this in other reviews and it’s true. It was extremely hot while running, and was even hotter while it was charging (charging cord was scalding too). Scary.Had to borrow a neighbors bike pump for my front tire. This product is a joke. Glad I didn’t need it while I was out on a ride.

My first pump had some issues, so I contacted customer service and they were extremely helpful, quick to respond and remarkably polite. I had a new pump in short order. The pump is well designed and easy enough to use once you get the hang of it. I plan to use it on some of our remote cycling excursions!

Just got this, but it’s a beautiful piece of equipment solid feel to it. The manual talks about having a car mode, but it doesn’t, that shouldn’t stop anybody from being able to feel higher with the customer mode.

For the price it's amazing that is such a smart product. There's one button that I found (I'm that person who doesn't read direction I must confess) but you hold down the power button for a few seconds to turn it on (so it doesn't just turn on the drain the battery by mistake), and it indicates the tire pressure in PSI on a small display. Because of its small size, the piston that generates air pressure is necessarily small, and it takes awhile to bring a tire up to pressure. But it fits in my back pack, it's charged via a standard USB cable and I'm glad to have it with me at all times in case there's a small leak, I can get my tire up to pressure in a few minutes. There are a couple accessories that I guess are for different kinds of tires, I only use the standard one for most bikes, and it screws on to the stem so there's a decent seal while it does its job. Love it. Maybe I'll get something AC powered that's a little faster for home, but like I said, you can put this in your back pack and it's smaller than a water bottle, so it's my little insurance policy on the road for always having air when I need it. Edit: discovered more functions; using the single button, touching on each of four sides allows you to make changes about the measure of air pressure (PSI for me) the type of product your are inflating, adjusting the cut-off pressure +/- I thought there might be a little more. I don't know how to use this for presta valves, kind of a gotcha when I got a new inner tube for my bike, but the kit here comes with a needle looking adapter and a couple other things I don't really understand but so far I haven't figured out with the hardware included how to pump up a presta valve type inner tube.

The media could not be loaded. Works great! And small enough to fit in the bike trunk. I bought this so I wouldn't be stuck away from home with a flat and don't like my little hand pump. I just happened to need it a short time later. It only took a couple of minutes.
