200W 20 Port USB charger

How do you tell if A charger is A fast charger?

Fast chargers are usually labeled with their output capacity.This is often measured in watts (W), but you can also find it in volts (V) and amps (A). A charger is generally considered "fast" if it has an output of 15W or higher.
For example, a standard iPhone charger provides 5V at 1A, which is 5W, while a fast charger might provide 9V at 2A, which is 18W.
It's important to note that the device you're charging also needs to support fast charging.If it doesn't, it will only draw as much power as it's designed to, regardless of how powerful the charger is.
Another way to tell is to look for specific fast charging technologies mentioned on the charger such as Qualcomm Quick Charge, Power Delivery (PD), Samsung's Adaptive Fast Charging, etc.
Fast chargers generally tend to be larger and heavier due to the additional technology and heat management required.

Product features

1. Output filter inductance: with output filter inductance, less text wave, can effectively protect the computer motherboard.
2. High-voltage AC filter: It adopts vibration stabilization bridge and thermistor, which can effectively buffer the high-voltage.
3. Safe charging: Built-in smart chip to prevent overvoltage, overcurrent and overload. Reasonable cooling holes can effectively dissipate heat and prevent the temperature from being too high.
4. Wide range of applications: Use the USB cable to charge your e-reader, ipad, tablet, bluetooth headset, portable speaker and any other devices.
5. Intelligent charging identification: Usb Fast Charging Station can charge 20 devices at the same time, overcharge protection and safe charging.
