Hello all,  

  

I have the circular type ground power connector on my Experimental aircraft, and I am wondering if there is a cost effective Large supply unit (meaning lots of  amps) to be able to run all the electrical whizzes in the aircraft while completing the build, Radios, multi-function nav screens, even the landing lights etc…. (I have run the battery for this but it dies out after about 40 minutes then I have to recharge  it for several hours to work on it again and the charge is not designed to power devices L ) 

  

I have seen the typical aircraft ones (like below) but that seems way expensive….. all I need would be 14volts and I can change the cable end is there some Bargin  out there that will turn on the computer based Devices in the aircraft while running of normal 110volt ac power from the hanger that I am just missing?

I guess another way to ask, is what’s in the BOX ? and maybe I could build one myself for Less ??? 

  

Thanks to all in advance 

  

Jeff.

JeffS,

Have you tried a good old fashion battery charger (not a maintainer).  There are lots of chargers that are capable of putting out 10-15 amps which should be plenty to keep the avionics & most accessories running.  (unless you have some need to run the high-current loads for really long periods of time?)

I have an ancient Sears charger that can put out about 15 amps all day long & I use it to float loads when I'm bench testing.

A quick goole search found this: Sears.com

Others on the list may have better recommendations for chargers,

Here is an EAA video on an alternate power supply. I installed it early in my construction and used it throughout. I have used it often since I started flying as well. I mounted the female end securely to the engine mount just inside the oil access door so I don't have to remove the cowl to put power to the battery.



I have a Schumacher 10/2 charger similar to the one already suggested. It is quite happy as long as I keep the power demand down.
