Part 5/8:
A crucial factor compounding the inefficiencies of personal fridges is their high-energy consumption. Testing unveiled that these Peltier-based coolers pull around 55 watts continuously, contrasting sharply with standard refrigerators that operate at lower wattages due to their use of sophisticated heat-pump technologies.
Despite being more costly up front, traditional refrigeration systems prove more efficient over time—consuming less power and offering far superior cooling capabilities. Calculations reveal a striking difference where the annual costs of energy for a typical Peltier fridge outpace those of a basic mini-fridge by a significant margin.
