I wish I had your bloody today. Thunderstorms kicked out power. Bator down to 85. M car is currently powering them to get the temps to settle.
Been way to lazy to figure out why our generator won't start up this year, I really have to address that... But, just in case I picked up a small cheap inverter (plenty enough for the draw of the incubators) at Harbor Freight for $20, I have two car batteries in the garage charged and ready to go... If the two batteries doesn't hold me, the Hummer has a built in inverter so I can idle that in the driveway with an extension cord worst case...
Here is the inverter I picked up, I used a 25% off coupon so it was under $20, my primary incubator only draws about 41 Watts with the fan and heating element running, the hatcher draws about 61 Watts fan and heater running, so I have plenty of overhead to run both...

Like I said I have not used it yet, but I figured it was cheap insurance...
