Portable generator?

I'm planning to fly at this summer at a gliderport that cannot/will not allow charging of batteries for electric gliders.
I know it's counterintuitive, and may even be heresy, and it hurts me to even think about this, but anyone have experience using a portable generator?
Thanks,

Good question.

I assume you are speaking of Air Sailing. In any event, I used a generator aboard my friends 5th wheel and it worked perfectly for my FES 16S battery packs.

I have used my 3600watt generator on my RV. Maybe there is another RV nearby that wont mind a plug in?

Thanks for your replies.
I'm thinking now if I can't bum a generator , maybe I'll take arrive with batteries charged, get towed, and fly it as a sustainer...

Hi Jeff,
Were you able to charge both batteries at once?
Thanks,
Bryan

Our group has a Honda EG2800i generator which runs at 2500 watts, starting 2800 watts which is enough to charge both batteries at once. 2500 watts at 120 volts is about 21 amps. The batteries, I believe, require up to about 18.6 amps to charge together. I usually charge at a 20 amp circuit with no problems but have the generator just in case. The generator weighs 67 lbs. Will run more than 8 hours at 1/2 charge rate so about 4 hours at full amperage. Almost always the batteries can be charged in less than 4 hours unless they are close to the lower limit. We paid slightly more than $1,000 new, mail order. You can find a listing on the Lowe’s website. Lynn Wyman, ESoaring LLC

Bryan,

Yes I was able to charge both off my RV generator. My generator is good for 30 amps and the chargers draw about 18 amps at the peak of charging. I use 1/2 gallon of propane per hour and a usual charge from 1/2 is about 3 hours.

I wonder if you buy a generator if you can get one that is for the UK or EU market. It would have the 220 volt sockets.

Jeff
