My diesel truck often has trouble starting in cold weather, and my old jump starter couldn't handle it. When the temperature dropped to 18°F last month and my battery was completely dead, I tried the DM1264 — it started right up on the first try. The clamps grip tightly and don’t slip. I've since used it to jump-start a tractor and a work van — the battery holds its charge very well. I also keep it in the garage as a backup power source; the USB ports are handy for emergency phone charging, and the LED light is very bright. If you need a reliable tool to start your vehicle — especially in cold conditions — this one really works. It paid for itself the first time I used it. Read more

Yes it's kinda expensive but works well no problems jumping off a semi. Used about six time and still hass almost a full charge. Only bad thing i can say is it's bulky and has some weight to it Read more

Pricey but it seems to work well after only a week of use on diesel generators. Read more

Our fleet has tried many jump starters, and the CAT797 is the only one that reliably starts all our Peterbilt and Kenworth trucks. The 30,000A peak current is no joke—it even fires up 50L diesel engines in sub-zero weather on the first try. The smart screen that shows voltage and error codes is a game-changer for us mechanics. Worth every penny. Read more
