This unit works great!! I have a 1976 Piper Lance. I plug the unit into the ground port, and it will charge and maintain my battery. In addition, when I turn on the battery master, it powers my panel. So, for those of you wondering, yes you can charge the battery and run you panel from the external port. I had it plugged in float mode on my battery and when I turned on the batter master you could hear the solenoid click and power was feed to the panel. I verified this through the JPI 900.

Well built product. Happy with my purchase.

The Piper plug is incorrect. The plug does not fit.

Have so far plugged it into the APU socket of a Cherokee and it not only powers the avionics but also charges the Cherokees battery, despite indications to the contrary in the marketing literature and instructions. But according to the electrical system diagram for the Cherokee, the unit should indeed charge the battery, which is in fact the case. The unit seems well-made, etc. There is, however, no indication on the unit or in the instructions or other documentation of where the unit is made.

This unit has plenty of power to run the avionics in my Turbo Arrow. Seems well built. You have to follow the instructions exactly No negatives. Id recommend this power supply.

Works as advertised.

Works as advertised and then some. Ad says power supply, but this is also a capable battery charger. Needs some minimum load in order to provide power, meaning one may need to turn on more than intended in order for unit to provide power. No adverse noise in my experience.

I sat in front of the hangar today learning some new things about the avionics in my arrow today. Computer simulator is just not the same and hard to read manual and twist knobs while flying. This unit works great. It will be needed when I upgrade my avionics in the Spring. I did notice a lot of static on one comm radio but not the other while listening to the tower. The gyros made an annoying sound which will be gone when the vacuum pumps are removed. Overall I am very pleased.

Exactly what I needed with fast delivery, thank you!

I just purchased the Piper Saratoga and it has a lot of new avionics that I need to practice on before flying. This power supply works perfectly without draining the aircraft battery thus allowing me to spend as much time as I want to work on the avionics without worry. It powers the entire aircraft electrical system just like the alternator would without the fuel consumption.

perfect!

Works great

Use on my PA32 Tubo Lance, works great. Good value, fast service.

I bought this for my 1972 Piper Arrow. It charges my battery and keeps it charged however, I got this primarily as a ground power unit so that I could power my avionics panel on the ground to load updates and play with the Aspen and Garmin 750, etc. There is very loud static caused by the power supply that bleeds through on the radios whenever it is connected, which is very annoying.
