Works as advertised. Only drawback was it took so long to ship and arrive.

Super happy with this power supply plug. Our intended use is for training on new avionics in the hangar. Works great, price is right.

Although I was only going to be using this unit as a power source so that I could run my new all glass panel on the ground, I read the previous reviews that talked about static in the audio when using the system. Since that did not apply to me I bought it anyway and use it as I intended to up grade the software without running down my battery. I have found however that I have NO static or audio problems when using this unit like some others have reported. Works great, I love it!

After a recent panel upgrade I wanted to be able to power things up in order to train without the possibility of draining the battery. This unit is much more attractively priced than several others. I would have happily given a 5 star rating save for one issue. Radio reception has a good bit of static due to a lack of an in line filter. However this is not a huge drawback as I don’t have a need to listen to the local traffic, only to change settings etc. As an added bonus it does come with a battery charging attachment.

Purchased to Learn / play with / Update Avionics on the ground in the Hanger My 1977 C182Q immediately came to life as I plugged the Schafer 12-volt power supply into its external ground power plug with the Master OFF and I was able to casually get my Garmin Flight Stream 510 set up and up avionics databases updated Given it’s late November I went ahead and turned all the lights on, lowered the flaps and looked everything over well while not on battery power - something I’ll probably do more often from time to time with this new capability

For ground operation/training to power your glass panel, this unit is excellent. That said, if you desire to use head sets for audio, listen to traffic as you train, this unit is NOT desireable. It puts out so much Rf intreference that all you hear is static. After discusssing findings with the manufacturing rep, I came to the conclusion it is working as designed....Just not good with audio.
