Works great, fabulous for anyone who needs to update their panel or charge the battery.

We purchased for our flying club for use on two Cessna 172s and two Cessna 182s. This provides steady power and allows us to review Avionics without running the engine. We have found that the order of connection and switches is different for each plane, which is more of an issue of how our planes are wired. The unit works well with all of them.

Great economical solution to powering up our glass panel to play, research and update avionics.

We primarily bought this unit for operation of a full panel of new avionics, and it works great. The term Cessna Style 3 Pin Plug was confusing, but it perfectly fits the external power port on our Beech B-95 Travel Air also. It came with a second adapter for battery charging, with large clothes-pin type clips. It will charge, then maintain a float on the battery if desired. Instructions provided are clear and simple for both functions. We are using it for avionics training and database updating, with no worries about running the battery down.

So far, used for about 4 hours in 3 sessions total powering avionics on ground in a C337G. Will not sustain power to hi-draw items, of course, but does not claim to. With avionics on, was able to run all non-LED exterior lighting for 30 seconds before battery indicated it was discharging. Appears to put out a steady 27.9-28 volts. Recommend for battery charging and short term (1-2 hrs) avionics usage on ground. Download and read manuals before ordering. Will need to order battery ring terminals separately.

Works exactly as advertised. I am able to power all my avionics on the ground with this unit. No issues whatsoever.

April 6, 2020

Works very well for providing equipment so you can learn equipment. It only outputs enough power to power up the systems. There is not enough power to run high draw equipment.

Exactly what I needed and it works. thank you

Q: Can you give me the DC output of this unit? (part: 11-05086)

This unit 11-05086 has a 20 Amp DC Output.

Q: Does this unit operate with 240 volts?

It is 100-240 VAC 50/60Hz.

Q: Some newer 28VDC aircraft have GPU input monitor circuits, that do not allow more than a 2 VDC deviation above/below 27.5 VDC. Will this unit not be suitable for these applications, then? Problemic aircraft include Beech C90B series with their triple-fed buss systems, and also the Pilatus PC-12/45 series are vulnerable as well.

Per the vendor: "The 11-05086 is current limited @ 28.8 VDC which is within the deviation you reference, it should be suitable."

Q: When plugged into the external power receptacle on my 172N, will it charge the battery as well as power the electrical system as the ad copy indicates, or is that only for some airplanes and not others?

Per the supplier: should charge as well in the absence of a load draw.

Q: How long is the cable with the connector attached? Regarding the 24V Power Supply with Cessna Plug

The length of the cable from the charger to the end of the receptacle is approximately 9-1/2 feet.

Q: Is the DC power filtered to eliminate output noise or hum to protect avionics?

Per the supplier: Because this unit requires a battery to be in the circuit it (the battery) acts as a filter capacitor for the DC.

Q: Is the charging unit itself a Schauer JAC2024H on this 24 VOLT PORTABLE POWER SUPPLY WITH CESSNA PLUG (part # 11-05086)?

Yes, the charger included with this kit is a Schauer model JAC2024H.

Q: Does the 24 VOLT PORTABLE POWER SUPPLY WITH CESSNA PLUG (part # 11-05086) come supplied with a cord to connect to the 240v ac power source, if so, is it a 2 pin US style And what cord length?

This comes equipped with a detachable AC cord that is 6ft. long. It connects into the charger with an IEC C13 style plug and has a North American grounded 3 prong style plug for the wall outlet. You would need to supply your own 240AV plug with an IEC C13 plug for the charger.

Q: What is the function of the equalizer?

Part # 11-05086 is a power supply to power the aircraft avionics on ground so the aircraft battery is not used/drained.

Q: It says Cessna Style 3 Pin Plug. Are there different plugs available for other planes or is this plug compatible with other makes? Specifically I have a 1982 B55 Baron.

The Cessna style 3-pin plug is commonly used with other aircraft manufacturers, such as Beechcraft, so it should work fine with your Baron.
