What wattage is more suitable for a car charger?

[CarlosFitz]

It is recommended to choose a 9V-2A (18W) car charger. Higher-power car chargers are more likely to cause damage or burn out electronic devices or electrical appliances attached to car accessories due to the output of alternating current. Installation method of car charger: Car chargers are divided into direct charging and dock charging. When charging a device through the car cigarette lighter socket, simply remove the cigarette lighter with the cigarette symbol, connect the device to be charged to the car charger with a charging cable, and insert it into the car cigarette lighter socket. Precautions for using a car charger include: Do not charge when the vehicle is turned off; Do not connect for charging when the vehicle is starting; Try to minimize charging multiple devices simultaneously or avoid charging high-power devices; Unplug the charger promptly after charging, as prolonged connection can damage electronic products.
