No more guesswork – just fast, accurate diagnostics that get you back on the road faster.
Powered by high-performance lithium-cobalt cells, the DM1264 delivers stronger high-current discharge and better low-temperature performance than ordinary LiFePO4 jump packs — ideal for semi-truck drivers in freezing conditions and fleet operators managing high-value equipment. Its 12-layer safety system prevents reverse polarity, short circuits, over-current, over-voltage, low voltage, over-temperature, and overload — protecting vehicles worth over $10,000 from costly ECU damage. Thick 4AWG cables and reinforced heavy-duty clamps ensure a firm grip on large battery terminals, reducing spark and poor contact risks for repair shops and roadside professionals.
More than a diesel truck jump starter, the DM1264 also works as a 64,000mAh portable power bank for phones, tablets, work lights and other essential devices through USB-A (QC18W), USB-C (PD output) and 12V DC output. Whether you are a long-haul truck driver needing to charge a laptop, a roadside assistance team working through the night, or an RV owner camping in remote locations, the integrated 2,000-lumen LED light, red/blue warning light and SOS modes provide extra visibility for roadside breakdowns, night repairs, fleet maintenance and emergency situations.
Engineered to perform in harsh temperatures from -40°F to 140°F, this semi truck jump starter is ready for winter starts in northern regions, hot weather in desert job sites, and demanding roadside conditions faced by truck drivers, construction crews and emergency responders. The complete kit includes the DM1264 jump starter, power adapter, car charger cable, 60-inch black nylon tie-down strap and user manual – convenient for use in a truck cab, repair shop, fleet garage or service vehicle. A practical emergency tool for professionals who cannot afford downtime.
Why does my jump starter arrive with low battery? Do I need to charge it before first use?
es. For safe transport, all units are shipped below 30% battery. Please fully charge it (approx. 4 hours) with the included 57W charger before first use, otherwise it may not have enough power to start a vehicle.
Can it start a completely dead battery (0V)?
Yes. The DM1264 can start a fully dead (0V) battery in just 1 second. This is one of its core advantages over standard jump starters that require minimum voltage to function.
Does it work in extreme cold?
Yes. The DM1264 is engineered to operate reliably from -40°F to 140°F . It uses premium lithium-cobalt cells that maintain strong discharge performance even in freezing conditions, making it ideal for winter starts in northern regions.
Does this support 24V systems?
No. The DM1264 is designed for 12V systems only. If you need 24V support for commercial trucks or heavy equipment, please check other models from the same brand.
Do I need to charge it after every use?
Yes. The manual recommends recharging the unit within 4 hours after use. This helps maintain battery health and ensures you are always ready for the next emergency.
