In this video, I tested the ETENWOLF S1, a super small cordless tire inflator that’s meant to live in your trunk so you’re not stuck when a tire is low. Etenwolf sent this one over, and I’ve worked with them in the past—so I was genuinely excited to see how this little pump actually performs in the real world. I unbox it, walk through the design, and show you the screen, button layout, and the built-in hose routing on the back (which is honestly a nice touch because it’s always connected and easy to tuck away). I also show what accessories you get, including the inflation needle stored under the unit, and how the default connector works great for standard tire valve stems (which is what most people will use anyway). Then I hook it up to a small tire and run it, showing how the PSI increases incrementally so you can see where you’re at while it’s filling. Overall, the setup was quick, it screwed on with no issues, and the compact size makes it easy to keep in your vehicle. By the end of the test, I was pretty impressed with how convenient and well thought-out it is for a budget-friendly emergency inflator.
