Woowind BP188 Bike Pump, The Pro Electric Bicycle Pump Tire Inflator Portable Air Compressor with Schrader, Presta and Dunlop Valve Adapters - 120~150PSI OptionsClimatePartner certified

Took me a few attempts to figure out the navigation buttons. I find putting the end piece on the bike tire BEFORE turning the pump on works best for an accurate pressure read.PROSroad bike pump accessory piece works like a charmPumps to the exact Pressure you set. Just set and let it fly!Portable - can throw in any bike bag and you barely notice it.ConsOnly downside is the pump does shut off if I need to do a big tire inflation.100% worth it for regular bike pumps.

I was surprised by how well the tire pump worked. It’s pretty powerful for being so compact. It can literally air up a vehicle tire and is easily portable which definitely helps on long distance bike rides if you happen to lose air pressure in a tire.

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.

I bought this in September 2022, and it has a 24 month warranty. In March 2025 (after warranty expired), the unit would no longer charge - I could get it to look like it's charging - flashing red and going to green, but when it was green again, the unit would not turn on. It turned out that the device is very cable sensitive. After trying a USB C to USB C, which didn't work, I used another USB A (charger) to USB C (pump) to get the behavior described above. I found the original cable for the device (in the device pouch), and that worked. Device shows green after charge, and will turn on. Assuming it's charged correctly, the pump works well - I use it for my bike and carry it on the bike with me for emergencies. The only issue I have with it involves the Presta connector for my bike. To avoid deflation issues on the tire, I end up putting the Presta connector on the valve first, then attaching the pump to the Presta connector.

Works great

Very easy to use.

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.

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.
