How do you know if a charger is fast or slow?

There are a few ways to determine if a charger is fast or slow:
1.Charging time: If you notice that your device charges significantly faster with a particular charger compared to others, it is an indication that the charger is fast.
2.Ampere (A) rating: Chargers with higher ampere ratings can deliver more current to your device, which results in faster charging.Fast chargers often have ampere ratings of 2A or higher, while slower chargers may have ratings of 1A or lower.
3.Wattage: Fast chargers typically have higher wattage ratings. The higher the wattage, the faster the charger can deliver power to your device.Fast chargers usually have wattage ratings of 18W or higher, while slower chargers may have ratings of 5W or 10W.
4.USB Power Delivery (USB-PD) or Quick Charge support: Fast chargers often come with USB-PD or Quick Charge technology, which enables faster charging for compatible devices. If your charger supports these technologies, it is likely to be faster.
It's important to note that the charging speed also depends on the device you are charging.Some devices may not support fast charging or require specific chargers to achieve faster speeds.
