How to tell if a mobile phone charger supports fast charging

In the past, we didn't need to pay attention to the current amperage of the charger because the current required by electronic products at that time was small, but in fact, it also needed to match the current amperage.

Many mobile phone chargers now support fast charging, so the requirements for the current value are relatively high. In the case where the output voltage of the charger corresponds to the power supply parameters of the electronic product, the current more significant than the requirement has no effect because the actual current is determined by the load (such as a mobile phone), not the output current of the charger. Most loads have an intelligent charging management circuit, which will automatically stop when fully charged. You will dynamically adjust the current according to the load conditions during charging or working.

So how to check whether the charger supports fast charging? If it is not original, we can also confirm by looking at the logo on the charger. If the charger has the word "SuperCharge" on it, it also supports fast charging. If the USB port of the data cable and the fast charging port is purple, it also means that the data cable supports fast charging. There is a "lightning" mark on some data lines, which also means that the data line supports fast charging. Of course, the absence of this mark does not mean that the data line does not support fast charging.

Usually, when the power of the mobile phone exceeds a specific value, to protect the power, the system will automatically disable the super-fast charging function.

The above is some information on how to tell if a mobile phone charger supports fast charging. We would be very honored if it helps you. Are you still looking for a reliable phone charger manufacturer, contact us.
