Mobile Fast Charging
What is Fast Charging?
Fast charging is a technology that significantly reduces the time it takes to recharge a mobile device’s battery. Standard charging typically provides a current of 5W (5V/1A), whereas fast charging technologies can deliver higher power levels, such as 15W, 25W, 45W, or even higher. This increase in power transfer speeds up the charging process.
How Does Fast Charging Work?
Fast charging relies on increasing the voltage and current delivered to the battery. To support this, both the charger and the device must be compatible with fast charging standards. The primary components involved include:
- Charger: Must be capable of delivering higher power.
- Cable: Needs to handle higher currents without overheating.
- Battery: Must be designed to accept higher charging currents without degrading.
