In this video I tested the Wolfbox MegaFlow 24 Pro portable tire inflator on my own vehicle to see if it’s actually a reliable tool to keep in the car for road trips and everyday tire maintenance. Wolfbox claims it can inflate a tire in anywhere from about 44 seconds up to 2.5 minutes (depending on tire size), and they even say a full charge can handle up to 23 auto tires. I’ve been looking for a dependable inflator to toss in my trunk, so I was genuinely excited to put this one through a real-world test. I walk through what comes in the box (hard carrying case, car charging cord, USB-C to USB-C cable, quick-connect hose, and adapters for bike tires and sports balls), then I show the controls and modes on the LCD screen. The big test was getting my tires from low pressure back up to my recommended 42 PSI. One tire read 37.7 PSI, and after setting it to 42 and hitting start, it filled to 42 PSI in under 30 seconds with auto-stop—way faster than I expected. It also impressed me because other inflators I’ve tested couldn’t hit 42 PSI for my Tesla, but this one did it with ease, plus the built-in flashlight (and SOS mode) is a nice bonus.
