A USB fast charger is a type of charger that utilizes technology allowing devices, particularly phones, to charge much more rapidly than with standard USB chargers.
Understanding USB Fast Charging
The technology commonly known as "Fast Charge" is technically referred to as USB 3.1 Power Delivery. This standard significantly enhances the power capabilities transmitted over a USB connection.
Key Capabilities and Benefits
USB fast chargers, leveraging USB 3.1 Power Delivery, offer substantial improvements in charging speed and power delivery:
- High Power Output: They make it possible to charge compatible devices at power levels up to 100W. This is a significant increase compared to older USB standards which delivered much lower wattage.
- Faster Charging: This higher power output translates directly into quicker charging times. As the reference states, it means you can charge your phone 2-4 times faster than you would with a conventional charger.
In essence, a USB fast charger is a charger designed to support standards like USB 3.1 Power Delivery to provide much more power to devices, enabling them to reach a full charge in a fraction of the time it would take with older, less powerful chargers.
