Understanding Fast Charging
What is Fast Charging?
Fast charging is a technology that speeds up the time it takes to recharge your device’s battery. For example, while a regular charger might take three hours to fully charge a phone, a fast charger can do it in just 30-60 minutes. for more detailed information on different types of charger, read our Ultimate blog on different types of charger.
How Does Fast Charging Work?
Fast charging increases the amount of power sent to your device by raising the voltage or current. Here’s how it works:
- Voltage: Regular chargers typically operate at 5 volts, but fast chargers can go up to 20 volts.
- Current: Fast chargers also increase the amperage (current) to transfer more power quickly.
Example: Samsung’s latest Galaxy S24 Ultra supports Super Fast Charging 2.0, which charges the battery from 0% to 50% in just 15 minutes.
