Frequently Asked Questions

Q: Can I use the 2835A to start an aircraft engine?
A: The 2870A GPU is adequate for piston engine start ASSIST ONLY. Its capacity is inadequate for turbine engine start assist and should be used for airframe systems power only. Do not attempt turbine engine starts with the GPU connected to aircraft. See the User Manual for details.

Q: Can I leave the BatteryMINDer connected for long periods of time?
A: Yes, the BatteryMINDer is designed to remain connected and will not overcharge or damage your battery.

Q: Does my GPU have Active Load Monitoring?
A: This feature was introduced in January, 2015. All GPUs produced since then have the feature, and older GPUs can be upgraded at the factory for a fee. Details.

Q: Does the GPU with BatteryMINDer work outside North America?
A: The GPU itself may be used with almost any voltage, but the internal BatteryMINDer is only compatible with a 100-127V AC power source. In countries with other voltage standards, a compatible BatteryMINDer must be purchased and used separately.

Q: Is the GPU BatteryMINDer compatible with Concorde batteries? 
A:  Yes, BatteryMINDer chargers inside our Ground Power Units do not require any special configuration to properly charge Concorde batteries.

Q: Why is Audio Authority selling aviation products?
A: Audio Authority was the original designer and manufacturer of ground power products sold by Enhanced Flight Group, LLC. The Enhanced Flight GPU shares technology with Audio Authority power supplies used for demonstrating mobile audio electronics in retail stores. After Enhanced Flight ceased operations in 2009, demand was still strong for these products, so they are now available directly from Audio Authority and also from our distributors, Sporty's Pilot Shop and Aircraft Spruce.
