Tips for using USB chargers include the following aspects:
Choose the right USB charger and charging cable: The charger should have a USB output port that can provide the voltage and current required by the device. The output voltage of a common USB charger is 5V, and the current varies depending on the device, usually between 500mA and 3A. The charging cable should be intact and the interface should be clean. Avoid using damaged or aging charging cables to prevent short circuits or unstable charging.
Understand the type of USB interface and charging protocol: Common USB interfaces include USB 2.0, USB 3.0/3.1, USB-C, etc. The USB-C interface has gradually become the first choice for high-end devices and fast charging technology due to its convenience of reversible plugging and powerful data and power transmission capabilities. Different versions of USB interfaces differ in current and voltage support, which directly affects charging speed and efficiency. In addition, when a device is connected to a charger or computer through a USB interface, a protocol handshake will be performed to determine the best charging mode. For example, Apple's Lightning interface can achieve fast charging with the PD (Power Delivery) fast charging protocol.
Reasonably allocate interfaces: Connecting devices with larger power requirements to the fast charging interface can improve charging efficiency. For example, smartphones usually require 5W to 18W of power, while tablets require 10W to 30W of power.
Avoid overcharging: Although modern devices usually have overcharge protection, connecting the charger for a long time may still cause damage to the battery. It is recommended to unplug the charger in time after full charging.
Use original or certified chargers and charging cables: Original charging cables and certified brand charging cables have low resistance, which can effectively reduce the loss of electric energy during transmission and ensure the stability and efficiency of charging.
Keep the device and charging interface clean: Dust and debris may affect the contact effect, resulting in interruption of charging or slower charging speed. Regularly cleaning the device and charging interface can ensure charging efficiency and safety.
