Boiling water being poured into a handle thermos cup for heat retention testing.

① Starting the Heat Test♨️

Day 1, 23:30 PM

We began our test by filling the thermos with boiling water and waiting overnight to check its insulation performance.

A thermometer reading above 50°C after 8 hours in the thermos cup.

② 8 Hours Later: Still Hot at 50°C+

Day 2, 7:30 AM

Our thermometer maxed out at 50°C, but the thermos clearly maintained high temperatures overnight.

Thermometer reading 41.9°C after 14 hours, before switching to cold test.

③ 14 Hours Later: 41.9°C

Day 2, 14:00 PM

After 14 hours, the thermos was still retaining heat. Now, we tested its cooling efficiency by filling it with ice cubes.

More than two-thirds of the ice cubes remain after 7 hours in the thermos cup.

④ 7 Hours Cooling Test: Ice Still Intact🧊

Day 2, 21:30 PM

The thermos demonstrated impressive cooling retention, keeping most of the ice intact for hours – impressive!

Ice cubes still present after 21 hours inside the cup.

⑤ 21 Hours Cooling Test: Half the Ice Left

Day 3, 11:00 AM

Even after nearly a full day, a significant amount of ice remained, proving the thermos excels at cold retention.

Final Verdict:
