Why hasn't the coffee I placed on top gotten hot after sitting there for so long?
- This heating pad belongs to heat conduction, the power itself is not high, about 30W.It usually takes 1-2 hours to heat from room temperature to 120-140℉. It is usually used for keeping warm, such as brewing a cup of hot coffee and putting it on the heating pad to keep the coffee warm.
- Please confirmed the material of the cup you are using.And the bottom contact area is large enough.(Cup material should not be too thick, otherwise it may lead to insufficient temperature, e.g. double glass with insulated cups)
