These portable power supplies are an excellent way to power your avionics on the ground while you train or practice in the cockpit. Especially helpful in learning how to operate glass cockpit avionics and panel mount GPS units. To use the Portable Power Supply plug the cord into an AC wall outlet, and then connect the 3-pin plug into the external power receptacle on your aircraft. Furnished with Cessna style 3-pin plug. Manufactured in U.S.A.
This unit can also be used as a battery charger, by using the battery clip adapter which is provided with the unit.
Works great! Charges my battery and upon reaching full charge it goes automatically into maintenance mode. Mine services flood batteries, as well as AGM/GEL batteries (like the one in my aircraft).
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!
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
Works as advertised. Only drawback was it took so long to ship and arrive.
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.
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.
This is a 12V / 25 Amp battery charger. We requested the information from the manufacturer and they directed us to the specification sheet. You can find this in the "Documents" tab or by clicking here.
Yes, see our part # 11-03158 for the plug only.
No, the 12 volt version can be used on 14 volt systems without damaging the system. Same goes for 24 volt version on 28 volt aircraft systems.
The three port adapter will power the panel, the alligator clips will charge the battery but will not do crank assist.
It is 120 or 240, it is auto sensing.
Yes the battery clip adapter is included.
Cyclic voltage for flooded batteries is 2.47v and 2.4v for agm and gell batteries.
Yes, this fits the 3 pin auxiliary power port on most Cessna aircraft.
It will work with any aircraft that has the cessna style plug. We recommend checking the charger port on your aircraft to see if it has the 3 pin style Cessna style receptacle.
