How to choose a car phone charger?

When choosing a car phone charger, key considerations include power matching, protocol compatibility, and safety protection. It is best to prioritize models that support mainstream fast-charging protocols such as PD and QC. For example, a 65W multi-port charger can meet the needs of devices like phones and tablets simultaneously. Brands like Xiaomi and Aohai excel in compatibility and efficiency, with prices ranging from approximately RM25 to RM288. For safety, look for overvoltage, overcurrent, and short-circuit protection functions, and choose products with flame-retardant casings. If the vehicle has a 12V cigarette lighter socket, ensure the charger supports 12V input; models with dual-voltage design offer wider adaptability. Those with sufficient budgets may consider models with inverter functionality to convert 12V to 220V power supply, but attention should be paid to power limitations. It is advised to purchase through official channels to obtain after-sales support and avoid using inferior products that may cause device damage.
