A $30 Peltier-based personal fridge with only 6-can capacity provides temperature reduction of up to 30°F below ambient but cannot achieve food-safe temperatures (below 40°F) in typical office environments and requires 24+ hours to cool beverages to only 45-50°F, making it unsuitable for food storage.

Unidentified Speaker — Thermoelectric cooling: it's not great. [CnMRePtHMZY]

Evidence Quote

in an office environment during the summertime where, say, the room temperature might be 75 degrees Fahrenheit, this thing will - at best - get the interior down to 45 degrees Fahrenheit which by US standards is not food safe... After 24 hours the temperature had plateaued at about 46 degrees... the actual temperature of the liquid in those cans was a slightly warmer 50 degrees.
