Building Your Own Mini Fridge? | Hackaday
Peltiers are actually most efficient at around half their rated power, because the heat transfer scales directly with I while the heat generated in the device scales at I^2

The largest difference between I and I^2 between 0…1 is at ½ which means the device will transfer the most heat with the least waste at exactly half its rated output. That’s why it’s a good idea to use two peltiers wired in series.

The less waste heat there is, the cooler the heatsink remains and the smaller the dT between the inside and outside heatsinks, which also improves the heat transfer efficiency. Overall, you can improve the performance 3-4x over the simpler cheaper design.
