3. Identification of insulation performance
The insulation performance of the vacuum insulated water bottle mainly refers to the inner liner of the insulated bottle.
After filling with boiling water, tighten the stopper or the thermos cup lid clockwise. After about 2~3 minutes, touch the outer surface and the lower part of the cup by hand. If you feel warm, it means the insulation performance is not good enough.
