This START PAC®’s maximum amperage output is 50 amps which is more than adequate for powering up most light 12V 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.
