I just bought this a week or so ago and have used it only once. It worked great and cranked my truck on the very first try!

I have an older V10 Excursion that doesn't get driven too often and is used more so on camping trips when we need a large vehicle. I keep the car on a trickle charger at all times but I do know the battery is older so I sometimes get nervous when I take it out for multiday trips. This was purchased for the possibility of needing a jump when we're in the middle of nowhere.

As far as features I have tested, the air compressor works ok and will pump up a tire albeit slowly but do feel confident it will work in a pinch when needed. The light on it works fine and all the functions otherwise work with no issue. It comes with a nice carrying case to store it and charged decently quick from medium to full with a standard usb-c connection.

As a mobile mechanic, this 3000 amp portable jump starter is powerful enough to start everything from cars to trucks and is compact enough to fit easily in my van. The safety features like reverse polarity protection give me peace of mind, and the built-in flashlight is a handy bonus for low-light jobs. Reliable, efficient, and a must-have tool for any mechanic on the go!
