Did I mention AC? Thats right, one of these on its own is enough to power my 7,000btu window AC unit. It's been going full blast for the last three hours and my room is ice cold. Sitting on my bed with the Genny right outside the window, I cant even hear it for the AC fan. Even better, she hasn't finished off a half gallon of gas yet. Meanwhile (back at the hall of justice) I can use the other one to cycle power to my chest freezer, kegerator, fridge and keurig.
I also rather like the redundancy these offer me. The old, one is none two is one philosophy. Even if one shit the bed on me I could use just the other one to power everything in cycles. Or if they both broke I have the option to pirate parts from one or the other to have one working unit. This also gives me the option to loan one to a trusted neighbor to keep their food cold at least.
ok, enough of my opinions, time for some pictures!

Pretty sharp lookin little juice boxes...

Air vent switch for the gas cap. This keeps pressure on the tank so you could store it full without the butane evaporating off, or stinking up your car or garage or what have you.

With the back access panel off.


And here with the parallel kit hooked up.
So there they are. If any one has any questions, or anything they'd like a better picture of or a load you'd like me to try to test just let me know and I'll do my best to accommodate.
ETA: I got these factory refurbished from an Ebay champion seller for 375 apiece shipped.
