Product works perfectly with my 2007 Diamond DA 40 XLT - allowing me to use my Garmin G1000 system (both PDF & MDF) without turning on any switches (runs without Master or Avionics switches on). In my case - it is required to have the unit switched on GEL battery mode. Aircraft Spruce packaged and shipper the product on time which arrived in new condition without damage.

Purchased this for my 1972 E55 Baron to power my avionics on the ground so I could learn how to use the GPS etc. Couldnt have been easier to use just plug it in to the external power port on the plane and switch it on. Make sure you read your POH concerning external power. My master switch is left off and I just turned on my avionics master. Spent about 3 hours messing with the GPS units and setting them up perfectly. Well worth the money of this unit.

I bought this to charge my battery. It did not charge the battery so I wanted to return it for a refund. Aircraft Spruce was reluctant to give me a refund stating that if it was defective I would have to go through the manufacturer of the product. They even had me speak to the manufacturer to describe the issue I had with the unit. I was dumbfounded as to why I just could not return it for a refund. Then I was told my refund would be processed after they sent it back to the manufacturer. Again, I was dumbfounded as to why I would have to wait. I opted to exchange the unit for another one. Their return policy is somewhat confusing. On the one hand it states, If you are not satisified with your purchase for any reason, you may return it within 30 days from date of purchase. But I guess somewhere in the additional verbiage, that did not apply in my case.

Delivery as promised and product works as advertised. I’m pleased with the entire process.

Just got this 2 weeks ago and it worked as advertised in my Cessna Caravan G1000. My G1000 draws 16 amps when both PFD and MFD are turned on so the 20 amp capacity is adequate. A lot easier than hauling out the very heavy GPU on wheels to the plane.

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.
