I tested this device with a power supply that only delivers 7 volts and 6 A, that is 42 wats. Nevertheless the result was better than expected. In a room temperature of 30 degrees I get 2.5 degrees in 10 minutes. With a laser infrarred thermometer I read -1.5 degrees inside the cooled aluminium radiator. I am sure I can get temperatures below 0 at 30 degrees room temperature with 60 wats. I never seen such a powerful peltier cooler. I think the cooper pipes can eliminate heat at very high rate, maybe there is some fluid inside the cooper pipes that evaporates. I don't know how it works but with only 40-60 wats you can get below 0 temperatures. Condensation of water starts inmediatly after pwering up the device.
