Hello mate, ShekharKharat
Please contact Nothing Support from your CMF Phone 1. Settings>System>Feedback. Where did you purchase the Power 33W from?
The adaptor converts alternating current (AC) to direct current (DC). During this process, there is energy conversion and loss. The lost energy is released in the form of heat. In addition, the adaptor contains electronic components such as inductors and capacitors. When current flows through these components, they generate resistance, converting some of the electrical energy into heat. This is why the adaptor feels hot.
For your safety, please charge your device in a cool and well-ventilated environment.
