Re: 110 to 220 converter or new charger

I bought a RUSSCO Electric Vehicle SC 18-120/72-156 Charger and have had good luck.
list price is $645
I like the fact I can easily adjust both the voltage & current.
I bought the unit with auto shut-off.

I am looking at getting one of these: 110-220

http://www.dvdoverseas.com/store/index.html?loadfile=catalog6_0.html

for rare times I am able to opportunity charge.  I have a 220 Zivan NG-3 and I think it was John recommended this solution.  I asked Zivan if this would work and they said....

"but if the charger drew 20A at 240vac  then your transformer will be trying to draw nearly 40A from the 115vac circuit"

If that is true then I would trip everyone's breakers.  So if that is so I guess to get 110 opportunity charging I'll need a whole extra charger?

Any recommendations on a cheap 110 back up charger for 144V 6V floodies (GC-2) or a way to get the converter to work?


Thanks
