The Peltier-based personal fridge consumes 55 watts continuously whenever powered on, whereas a standard mini-fridge (roughly $100) consumes only 45-50 watts when actively cooling and averages only 21.7 watts over 24 hours due to thermostat-controlled cycling, making the larger device more energy-efficient despite higher capacity.

Evidence Quote

the blue fridge uses 55 watts all the time... Once the refrigeration circuit has stabilized, it pulls between 45 and 50 watts from the wall... I monitored its energy use when loaded up with 15 already-chilled beverage cans, and to keep them cool over three hours, it consumed just 65 watt-hours representing an average draw of 21.7 watts.
