I've just bought one of those small camping/"lazy fat footballer fan can't be bothered to go to the fridge" mini fridges, it will run on 12 volts or off the mains with a built in SMPS (yes had the back off it already)
now on 12 volts it uses 45 W but running on the mains it uses 64 W !!! over 30% more, surely this cannot account for loses in the SMPS ? or maybe it can ? the SMPS outputs 12 volts so its not running the peltier cell at a higher voltage from the mains...
at present I have plans to change the noisy little fan (8 cm) for a nice 12 cm fan keep it cooler and QUIETER
