I have a IGLOO car peltier cooler that I carry in my car.
It runs off of DC 12v but it comes with an AC adapter to plug it into 115AC outlet or an optional cigarette lighter cord for in vehicle use.
When I had it plugged in with the AC adapter, it pulled 65 Watts.
When I plugged it into the cigarette lighter in my car, it pulled 65 Watts
I was expecting a significant decrease in watts used running it directly off of DC ?
I thought without the AC adapter having to convert AC to DC I would see a large drop in power usage.
Where did I go wrong?
Thanks
