Frequently Asked Questions
Q: Can I use the GPU to start an aircraft engine?
A: The 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 GPU connected to keep my battery charged?
A: No, the GPU is not designed for long-term battery charging; however, there is another GPU model has a built-in BatteryMINDer brand charger that not only keeps batteries charged, but actually conditions and restores aircraft batteries to extend their service life. The BatteryMINDer is designed to remain connected for long periods of time, and will never overcharge or damage your battery.
Q: Does my GPU have the overload alarm and auto-shutdown feature?
A: In addition to the output meters, a GPU that has Active Load Monitoring sounds an alarm to indicate overload, and if the condition continues, it initiates an automatic shutdown. Active Load Monitoring 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.
Q: Does the GPU work outside North America?
A: The GPU itself may be used with almost any voltage, but if you have a GPU with an internal BatteryMINDer, it 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.
