"…doubled battery life
and saved $3000."

TBM pilot Laurent Jouët
tells his story.


From our years of building high current DC power supplies for demonstrating mobile electronics and our continuous involvement in general aviation since 1980, comes our line of Ground Power Units to safely power cockpit and airframe systems with clean, stable 28-volt DC power. We also distribute the aviation-specific BatteryMINDer® and provide wiring kits for FAA-certified aircraft to simplify installation and increase safety.
