Drinks cooler?

Please think:

• Your refrigerator at home is probably about 120 watts.
• Open the refrigerator door and leave the door open.
• Now watch your drinks in the open refrigerator as they become warmer and warmer.
• Now the compressor (120W) is observed as it runs without interruption.
• Now look at the current meter how this diligently turns/counts its rounds.
• … after 4 hours you can cancel the test.

Conclusion:

• After 4 or more hours, the drinks have warmed up in the refrigerator, instead of cooling.
• Your electricity was still consumed
• 120W * 4h = 480 Wh (watt hours), do you have a battery with 480 Wh? It costs about 300-500€
• Screw all insulations and plastic parts / plates from the refrigerator. And put the rest on the table. Ready is your cooling plate for drinks.

Find the mistake.

Good luck!
