The wattage of a charger is calculated by multiplying the voltage (V) by the current (I):
Watts (W) = Volts (V) x Amperes (A)
For example, a charger with a rating of 5V and 1A would provide 5W of power.
The higher the wattage, the faster the charging speed. Most modern devices require higher wattage chargers to take advantage of faster charging speeds.
Faster Charging Standards
In recent years, several fast charging standards have emerged to address the demand for quicker charging times. These standards include:
- Qualcomm QuickCharge (QC)
- VOOC (Voltage Open Loop Multi-step Constant-Current Charging)
- USB Power Delivery (PD)
- Fast charging (adaptive fast charging, rapid charging, etc.)
These fast charging standards use advanced technologies to increase the wattage and speed of charging. For example:
- QuickCharge 3.0 can deliver up to 18W of power
- VOOC can deliver up to 20V and 5A, resulting in 100W of power
Why are fast charging standards important? Faster charging speeds mean you can get back to using your device sooner, which is especially important for busy users who can’t afford to be without their devices for extended periods.
Device Compatibility and Safety
When using a 1A charger with a device that supports faster charging, there are a few things to keep in mind:
- Device compatibility: Make sure the device is compatible with the 1A charger. Some devices may not charge properly or at all with a 1A charger.
