There are approximately thirty 110 volt and thirty 220 volt NEMA plugs in use.Also, customers have various receptacle at their hangars and MRO facilities and may require specific AC cord length to meet their requirements. Due to these facts, we do not automatically provide AC power cords. If you provide the NEMA plug number and specify the AC power cord length you require we will build a cord to be shipped with your unit for a small fee.

Could this unit be used for starting King Airs?
Some of the new King Air or King Air conversions are voltage sensitive. When our 28V units are fully charged, they will read about 30.5V. If there are no voltage sensitivities, then the 3328 Special would be the best option. If there is a voltage sensitivity, then you would need the 3326 Special.
