Plug-in seat heaters affect battery?

What is the current demand or the wattage of these heaters.

They wont drain a battery. Anything that draws too much current is going to blow a fuse. Checks the specs of the pads and the plugs. Both plugs are not the same size but I forget which one is smaller.

 

The outlets are alive when the car is not in ready mode. Even if the heaters only draw 5 amps each the battery could be quickly drained particularly if the 12 volt battery is not new. If the battery is original in a 2006 car it may only take a matter of minutes to discharge. The seat heater panels should be connected so that they can only operate in ready mode. Any other method is asking for trouble.

Man. euro prii are better in so many ways. our outlets all turn off when we hit the power button off. it would be nice if one would remain hot. and we have that stupid bladder...

 

The European versions are on with one or two pushes of the start button without the brake being operated for ready mode. In those two modes I think they are normally called "accessory" and "Ignition on" the sockets are on, but the 12 volt battery is not being charged. Check it out.

There was an "always on" kit for the Gen2 Prius offered by Elearnaid a while back.

I have installed two OEM-like seat heaters(under the original seat covers) in my 2005 Prius with low-off-high buttons, these are more powerfull than your cigarette lighter powered seat heaters, and i didn't see any loss in mpg or any adverse effect due to battery draining. The car inverter has more than enough power to sustain your 70-80W / 2 seats. As a comparison mine are 60-70W/seat, so don't worry.
