Can the car cigarette lighter be used for charging?
1 Answers
Car cigarette lighters cannot be used for charging, for the following reasons: 1. Different voltage: Unlike household sockets, the cigarette lighter operates at 12V, while mobile phone charging requires around 5V. 2. Impact on electronics: Since the cigarette lighter is directly connected to the car battery, when the car starts, the current will suddenly increase. The cigarette lighter itself has no protection. However, electronic devices require a constant power supply for charging. Sudden current fluctuations can cause damage, and prolonged use under such conditions will reduce the lifespan of electronic products.
