What is the JetGo 550Mti?

The JetGo 550Mti is a diesel-electric hybrid ground power unit for powering aircraft with 28.5V DC requirements. The lightweight and extremely portable 550Mti provides 550 amps continuous power for avionics, maintenance, and air conditioning on the ramp along with providing up to 2300 amps max for starting.

These units are great for corporate flight operations, FBOs, military, regional airlines, and aircraft Maintenance, Repair, and Overhaul (MRO) facilities.

  • 550 continuous amps at 28.5 volts DC
  • 2300 peak amp start capability
  • Kubota four cylinder turbo-diesel engine
  • EPA Tier 4i and EU Stage IIIA emissions compliant
  • Soft-start and onboard aircraft protection
  • Efficient fuel consumption: 0.8-1.5 gallons (3-6 liters) per hour (depending on load and atmospheric conditions)
  • Extremely quiet: Less than 63db at 20 feet (at full load)
  • Includes 30-foot MS3506 military spec output cable with standard NATO aircraft plug


  • One-button starting system
  • Can be used without engine operating as a hangar static cart, producing 24 volts for maintenance functions
  • Easy to move into service position by hand - only 1,367 lbs/620 kg (dry)

  • "Easybrake" foot activated braking system and auto brake-release
  • JetGo's trademarked "Zero Bleed" auto shutdown low fuel protection feature will shut down engine before running out of fuel, saving costly and timely fuel line bleeding procedures
  • 24V starting power remains in hybrid batteries even if engine shuts down due to inadequate fuel supply (preventing hot starts)
  • Large control panel with easy to read voltage & amp meters with bright contactor "ON" light
  • LED safety running lights illuminate when unit is operating
  • Custom engineered fiberglass shell with rounded edges reduces the potential for aircraft damage should unplanned contact occur
  • Marine grade shell and stainless steel hardware provide corrosion protection for any operating environment
  • Durable powder coated tubular steel chassis
  • Stainless mesh openings for airflow keep out unwanted guests and foreign objects

You Ask. We Help. Your FAQs.

Will leaving the JetGo outside in the hot sun hurt the unit?
The only harm from the sun would be the fading of the orange casing. If it is intense sunlight, you can use marine wax that will help protect the casing from any fading.

Overall pleased with this product. It appears to be very well built, and user friendly. It was delivered fully assembled and ready to go right out of the crate. We are pleased with the safety features, and the cool down function, which will decrease the wear and tear on the engine and generator. This is a fine piece of equipment, and we expect to see years of worry-free service out of it.
