Heavy Duty Jump Starters & Power Supplies for Trucks & Buses
A truck or bus that won’t start in the morning doesn’t just cost time, it costs contracts, penalties, and driver confidence. START PAC® manufactures heavy duty jump starters and battery packs for semi trucks, long haul trucks, and commercial bus fleets. Portable, American-made since 1997, and built to start large diesel engines without another vehicle, a generator, or AC power. One unit in the cab or the depot is all it takes.
START PAC® portable jump starters are available in 12V, 24V, and dual 12V/24V configurations — covering the full range of commercial truck and bus electrical systems. No AC power, no second vehicle, and no waiting for a service call. One operator with a START PAC® unit can start any diesel truck or bus on the fleet, anywhere.

The Power Challenges Truck & Bus Operators Face
Commercial trucks and buses run on tight schedules where a failed start is never just a mechanical inconvenience — it is a business problem with real financial consequences.
- Large diesel engines demand high cranking current — Semi trucks and heavy-duty buses run large-displacement diesel engines that require far more cranking power than any passenger vehicle. Consumer-grade jump starters are not built for this application.
- Dual-voltage fleets — Older trucks and light commercial vehicles run 12V systems. Heavy-duty semi trucks, coaches, and buses typically run 24V. Fleet operators managing mixed vehicle types need a single unit that covers both.
- No second vehicle available — In depots, remote layovers, and roadside breakdowns, there may be no other running vehicle to use for a jump start. A self-contained portable starter removes this dependency entirely.
- Cab electronics drain starting batteries — Long haul drivers run TVs, microwaves, refrigerators, and charging equipment from the cab battery overnight. By morning, the starting battery is depleted. This is one of the most common causes of fleet morning delays.
- Bus fleet scheduling pressure — A bus that does not start on time does not just affect one route — it cascades through an entire day’s schedule, impacts passengers, and creates stress for depot managers and drivers alike.
- Cost of commercial delays — Temperature-controlled freight, time-sensitive deliveries, and penalty clauses mean that a single failed start can cost far more than the equipment needed to prevent it.
Why Fleet Operators Choose START PAC®
START PAC® has been manufacturing portable starting equipment in Las Vegas, Nevada since 1997. The truck and bus product line is built around one principle: get the vehicle started, first time, without relying on anything else.

Who Uses START PAC® for Trucks & Buses
START PAC® truck and bus starting units are used across commercial transport operations of all sizes:
- Long haul and over-the-road trucking companies managing fleets of semi trucks on national and international routes.
- Bus depot operators running scheduled passenger services who cannot afford morning start failures to delay route departures.
- Commercial vehicle fleet managers responsible for mixed fleets of 12V and 24V trucks, vans, and buses.
- Owner-operators and independent truckers who carry a START PAC® unit in their cab as insurance against roadside battery failure.
- Temperature-controlled freight operators where a failed start risks cargo loss and penalty clauses.
- Coach and charter bus operators running tourist, school, and private hire fleets from central depots.
- Breakdown and roadside assistance operators who need a self-contained starting solution that works without a second vehicle.

FAQ
What jump starter do I need for a semi truck or heavy-duty bus?
For semi trucks and heavy-duty buses running 24V diesel engines, the START PAC® Earth Gear™ or Model 1324-1QC™ are the recommended choices — both deliver the sustained cranking output required for large-displacement commercial diesel engines. For fleets running a mix of 12V and 24V vehicles, the Model 2412 CE™ covers both systems from a single unit. Call 844.901.9987 and the START PAC® team will confirm the right model for your specific vehicles.
Can a START PAC® unit start a truck without another running vehicle?
Yes — this is one of the primary reasons fleet operators choose START PAC®. All units operate entirely from their onboard battery pack. No jumper cables, no second running vehicle, and no external power source required. A driver can start a stalled truck in a remote layover, a loading dock, or on the roadside completely independently. This is especially important for owner-operators and solo long haul drivers with no support vehicle available.
What is the difference between 12V and 24V — which does my truck need?
Most light commercial vehicles, vans, and smaller trucks use 12V electrical systems. Heavy-duty semi trucks, coaches, and commercial buses typically use 24V systems. If you manage a mixed fleet, the Model 2412 CE™ covers both voltages from a single unit, eliminating the need to carry or stock two separate starters. If you are unsure which voltage your vehicles use, check the battery label or call the START PAC® team with your vehicle make and model.
Why do truck starting batteries fail overnight in the cab?
Long haul truck drivers run substantial electrical loads from the cab battery while parked — TVs, microwaves, refrigerators, phone chargers, fans, and other equipment. In many countries it is also illegal to idle the engine overnight. This combination regularly depletes the starting battery to the point where it cannot crank the engine in the morning. A START PAC® portable starting unit kept in a cab storage compartment means the driver can start the engine immediately without waiting for roadside assistance or another truck.
Can one START PAC® unit service an entire bus depot fleet?
Yes. A START PAC® unit with a fully charged battery pack can perform multiple starts before needing recharge. For depot operations where multiple buses need to be started each morning, the Quick Change battery system on select models allows a fresh battery pack to be swapped in under a minute, keeping the unit in service continuously. For larger depot fleets, the START PAC® team can advise on the right number of units and configurations to cover your daily start requirements.
How durable are START PAC® units in outdoor and all-weather conditions?
All START PAC® units are finished with heavy-duty powder-coated cases that protect against wear, corrosion, and weather exposure. Optional all-weather covers are available for select models to provide additional protection during outdoor storage. Units are designed to withstand the temperature cycling, vibration, and environmental exposure of commercial transport depot and roadside environments. START PAC® has been manufacturing starting equipment since 1997 and its products are deployed by fleet operators in all climate conditions worldwide.
Does START PAC® offer solutions for both diesel and petrol/gasoline commercial vehicles?
Yes. START PAC® starting units cover both diesel and gasoline commercial vehicle engines. The product range spans 12V and 24V configurations, covering the full range of commercial vehicle electrical systems. Diesel engines — particularly large-displacement truck and bus diesels — require higher cranking current than gasoline engines, which is why the Earth Gear™ and 1324-1QC™ are specifically recommended for heavy diesel applications.
What warranty does START PAC® offer on truck and bus starting units?
All START PAC® products include a 1-year warranty on workmanship and materials and a 30-day money-back guarantee. If you are not satisfied for any reason, return the unit in new condition within 30 days for a full refund. The START PAC® team is available by phone at 844.901.9987 or 702.982.7089 during business hours for product selection, technical support, and after-sale service.
