What is USB Power Delivery?

USB Power Delivery is a standard that can provide more power than before, up to 100W of power through USB. USB Power Delivery uses a USB (Universal Serial Bus) cable, which enables fast charging. One universal PD charger will be able to power a wide variety of different devices.

The USB Power Delivery standard allows for voltages of 5 V, 9 V, 15 V, or 20 V, as well as power levels of up to 100 W.

Features of USB Power Delivery

USB PD chargers can be seen everywhere in life and work. The new USB Power Delivery standard has come to popularize the application of USB power supply on various devices and reduce the use of power cords.

USB power delivery's biggest pro is power levels up to 100W. The USB power delivery is fast charging and widely used. It has high power, shortens charging time, and optimizes the convenience of mobile applications. Meanwhile, USB Power Delivery is bidirectional, allowing devices to transmit data and charge at the same time.

Another great feature, power can be supplied and received between devices. The Source (power delivery) side/Sink (power reception) side can also be swapped. This allows charging without generating unnecessary heat. Within the compatible range of devices, it can avoid overcharging during transmission.

How Fast is USB PD Charging?

USB PD can charge your device up to 70% faster than standard 5W charging. This means less time for your smartphone to reach 100% charged. When you need a quick battery boost immediately, a quick 10-minute charge with USB PD may be all you need.

How Does USB PD Charger Work?

First, when the USB PD charger is connected to the charging device, it will tell the charging device through the CC line how many voltages the PD charger can provide and the corresponding current.

Then, the charging device understood the power supply capability of the PD power adapter. And it will choose one of the most suitable power supply methods and request data packets from the charger.

Note: if the USB PD charger cannot provide the voltage supported by the powered device, then PD fast charging cannot be performed.

Therefore, when choosing a PD charger, the higher the voltage levels. There are usually 5 levels, which are 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/2.25A.

How Safe Is It to Use the USB PD Chargers?

The USB PD chipset always delivers exactly the right amount of power. The charger recognizes the connected device and negotiates the required power to charge it as quickly as possible, whether it's a smartphone or a laptop. This negotiation ensures a quick charge without delivering too much power or damaging the device's circuits. 

Nowadays, most mobile phones are equipped with PD fast charging technology, which greatly improves the charging speed. In the past, it may take several hours to charge the phone up to 100%. Now it may only take an hour.

It saves a lot of time for mobile phone charging. It is really good to have such a faster charging experience than before. However, there are still some users who think that the PD fast charging technology is not safe and may cause damage to the battery of devices.

There is no need to worry too much. Now, most mobile phone brands are developing toward fast charging. There is also an intelligent battery management system in the mobile phone, so it automatically turns on smart charging protection when charging in different situations.

That is to say, during fast charging, the mobile phone will be automatically protected. The USB PD charger won't damage the service life of the mobile phone battery. But note here: Higher wattage charging devices necessitate special cables capable of carrying extremely high currents. Otherwise, the risk of cable fire exists.
