Whether you need mobile ground power for remote airstrips or hybrid solutions for high-volume Aircraft Maintenance, Repair, and Overhaul (MRO) operations, START PAC® provides reliable, durable, and customizable GPUs—all built in-house. With exceptional quality, a 1-year warranty, and outstanding after-sales support, we ensure your operations run smoothly.

Starting Units

Available in portable lead-acid, portable lithium, mobile lead-acid, and rail/locomotive configurations

START PAC Starting Units are high-power portable and mobile batteries built to start any type of electrically-started engine — from aircraft turbines and helicopters to heavy trucks, locomotives, and mining equipment. They’re designed specifically with voltage-sensitive aircraft in mind, offering 24V, 26V, and 28V options so operators aren’t stuck trying to force a standard 28V jump starter onto a system that can’t take it.

  • Patented Quick Change design lets you swap out a used battery safely in minutes, cutting maintenance downtime
  • Protects costly onboard aircraft batteries and delivers a reliable, cool turbine start even after sitting out in the cold
  • Lightweight lithium-ion options make it easy to carry reliable starting power to remote locations

Power Supplies

Military-spec versions available for defense and aerospace OEM applications

START PAC Power Supplies deliver continuous, clean DC power for avionics testing, cockpit maintenance, and ground support work — without ever running the aircraft’s engine. They plug into any AC wall socket and supply no-duty-cycle power for as long as it’s needed, at a voltage matched to what the aircraft would see under normal generator power. Important distinction: these are for maintenance and testing, not for starting engines or charging batteries — that’s what the Starting Units and GPUs are for.

  • Offered in 12V, 24V, and 28V configurations, with amperage ranging from 25A for basic avionics checks up to 400A for full cockpit power, including air conditioning and searchlights
  • Keeps onboard batteries topped up and protected from deep discharge, extending their service life
  • Covers everything from GPS updates and transponder/radio maintenance to entertainment system testing and static exhibition lighting

Ground Power Units (GPU)

Models include the patented Quick Change design for battery swaps in under a minute

START PAC Ground Power Units combine engine-starting capability with the clean, maintenance-grade power supply of the Power Supply line in a single unit. They’re built for operations that need both reliable engine starts and safe system power on the ground — ideal for fleets, remote airstrips, and high-throughput MRO operations.

  • SUPER PAC model line available in Lead Acid or Safe Lithium-Ion technology, with 24V, 26V, and 28V options to match voltage-sensitive aircraft
  • Delivers up to 400 amps of continuous, clean, no-duty-cycle DC power — enough to run air conditioning and full cabin systems during maintenance or software updates
  • Free-running combination units (Ranger and Hi-Brd 4) use eco-friendly diesel engines and permanent magnet generators for up to 150–300 amps where AC power isn’t accessible
  • START PAC GREEN is the world’s first emission-free GPU, running on a large 26V battery bank at roughly half the operating cost of a comparable diesel unit
