How to Make USB Charging in Cars Faster?
1 Answers
Slow USB charging in cars is often unavoidable, primarily because most vehicle USB ports are designed for data transfer between the vehicle and mobile devices, not for charging phones. Therefore, car USB ports can only charge phones at a slow rate. For faster charging, a power bank is still the best solution. Here are the details: 1. Avoid using cigarette lighter adapters for phone charging: If you must use the car's USB port to charge your phone, note the following: If you choose to purchase a cigarette lighter adapter for phone charging, avoid connecting your phone while the engine is starting and prevent overloading the cigarette lighter power supply. The power output of such adapters is often hard to control, increasing the risk of spontaneous combustion. Additionally, it's advisable to unplug the car charger after turning off the engine. This not only reduces the load on the car during startup but also decreases fuel consumption. Lastly, opt for reputable brands when selecting a car charger to ensure quality. 2. Current: Ensure the car charger's output current is not less than the phone's maximum rated input power. For example, a car charger outputting 5V/2.1A will charge a phone with a maximum rated input of 5V/1A at 1A and a tablet at 2A, enabling faster charging. The opposite scenario not only slows charging but also causes excessive heat, potentially damaging the phone's battery over time.
