USB-C and Power Delivery Explaining

Situated on the face of PD Gan charger are two new ports: USB-C and USB-C Power Delivery. The first is merely a USB-C port that operates using the latest USB 3.1 charging standards at up to 3 amps. The second supports a dynamic fast charging technology called Power Delivery.

Power Delivery (PD) is a specification for handling higher power and allows a range of devices to charge quickly over a USB connection. It operates by facilitating a conversation between two devices to negotiate a power contract so they can determine how much power can be pulled from the charger. Power Delivery starts at the 5V setting and is configurable up to 20V. Using a standard USB-C cable, it can handle up to 65W, and will go up to 100W using a designated EMCA cable.

Another point of interest regarding Power Delivery is that it allows for power to flow both ways, with no set direction based on circuit or connection. For example, if you were to connect two phones that support Power Delivery with a USB-C charging cable, one phone could charge the other and vice versa.

Choosing The Right Charger 65W PD Fast Charger

When it comes to selecting the right charging solution for your USB-C device, there are a few things to keep in mind. First, Power Delivery rating is not the same as power bank rating. A power bank rated at 65W, for example, may refer to the the total output of all ports. Just because it includes a USB-C port, does not necessarily mean that port supports Power Delivery and will output 65W on that one port alone. Instead, keep an eye out for a charging solution that includes a USB-C port with a specific Power Delivery rating of up to 65W. Next, watch out for the voltage supported by the charger. Most only support a few fixed voltages which you’ll want to verify are supported by your device for the fastest charge.

In order to ensure you are getting the most from your charge source, be it a USB-C power bank or power station, it’s best to take a look at the adapter that came with your device and match the ratings with those of the charging device. Otherwise you may get stuck with a slower than expected charge rate.
