This START PAC®’s maximum amperage output is 25 amps which is more than adequate for powering up systems on most light 24V aircraft cockpits. When you’re using this mini power supply, the aircraft’s electrical system can be powered up for GPS programming and light duty maintenance, bypassing the aircraft battery and thus preserving it from unnecessary wear. This means that the on board aircraft battery is conserved for starting only. The environmentally responsible, low VOC powder coating protects the unit from wear, tear and poor weather conditions.

All START PAC™ products come with a 1-year warranty on workmanship and materials.*

Please handle this unit in a responsible manner. START PAC™ is not responsible for damages caused by misuse or neglect.
