Review on 🔧 LUMITECO 1/4-inch Brass Tire Inflator Lock-On Air Chuck - Mini Portable Tire Inflator Chuck Hose End with Barb Connector for Hose Repair (2 Pack) by Alberto Brewster

It's a little hard to parse. The device itself is well made with excellent materials, so it deserves a 5 in this regard. However, the potential difficulty lies in the means by which it holds the seal on the valve. As shown in the picture, squeeze the silver lever to open the clamps, squeeze and hold the valve to create a seal, then release the clamp lever and allow the handle to hold the device in place position while the tire is inflated. One tire works fine, the other doesn't. The difference lies in the tire valve stems. both are standard manifold valves, but they are different enough that this jaw design likes one valve and not the other. The 90 degree lever lock pump I replaced uses a rubber "donut" that compresses around the valve stem and installs and holds a ton of different tires with no leaks. It was plastic so I thought it might be worth trying to make it all metal like this device as I knew in advance from the photo that the jaw clamp is different from the compression donut. I didn't expect it to be so sensitive to valve stem size/design. I might just have some weird wands, so this inflator might work for you.
