Use of White Lighting GPU with Cessna T182T

I am interested in purchasing a White Lighting GPU for my 2006 Cessna T182T with g1000 avionics. Does anyone have experience with using one with their C182? The salesman does not know if I should get the 35 amp model or the 50 amp model (24/28V model). Does anyone know how much juice the avionics will pull when they are first turned on?

I would use the unit to only do database updates and to play with the g1000 system while the plane is shut down.

    Hi Rayanne,

    Hopefully other 182 owners might have some first hand experience for you but with regard to purchasing the 35 amp model or 50 amp model, you might have a look at the capacity of the aircraft alternator. It has to be sized to run all of your avionics in flight so that would give you a ballpark for a GPU. You could also pose this question to the A&P/IA that does your annual inspections. I am sure they can offer good advice. Do not overlook the cost of adding a quick connect system for attaching the power supply.

    Regards,

    Mike
