Great power port. Highest amp rating of all the FAA approved USB power ports (even with both ports in use at the same time). Smallest panel hole so most existing cigarette lighter ports can be converted if there is enough back panel space for this power port. As far as the DSub pins the soldering isnt a big deal but I just ignored the included connector and used a more common standard Dsub connector with quality barrel connectors using a quality crimp tool. Works great. I made a template for the two attachment screws on my computer and printed it out at 100% scale on package mailing label paper. Then stuck it to the panel to drill the holes in the right place. This port has the most power and best bang for the buck compared to all other FAA approved models.

I installed the unit in my C182 in 2017. I recently upgraded my tablet from an iPad Air 2 to an iPad Pro 11. The new iPad will not work at all with the Ifdr 250-101. I have contacted Guardian and they confirmed that the new iPad Pros will not work with their unit and they have been unable to provide a fix for the problem.

I purchased this a couple years ago. It can charge a phone and an iPad, but not two iPads. When I try to charge two iPads, the unit shuts down and wont charge either.

Very disappointed in the unit. The electrical connection is attached to the charger via a DB15 VGA monitor connector that we have to solder and piece together. The homemade connector adds a couple of inches to the depth of the installed unit. Only two terminals are needed. Makes no sense. Also, they do not provide a metal pattern of the panel layout. Good luck with the laying out the counter sunk holes. There are others on the market, think twice before purchasing this unit.

Q&A

Q: We want to install one in our 1999 172 to power iPads, etc. Do we need to add a voltage converter to drop the power from 28 volts down to 12 volts?

No, this unit can be used in either 12v or 28v aircraft environments.

Q: Is the the iFDR Dual USB 250-101 Power Supply for Instrument Panels shielded to prevent radio interference?

Yes, this unit is Electromagnetically (EM) shielded to prevent static and noise on your VHF radio when charging.

Q: I see in your installation drawings that only a circuit breaker is shown. Is it acceptable to install unit with an inline fuse instead and if so what amp fuse is required?

You can use a fuse but a circuit breaker is highly recommended.
