What You Need to Know About USB-C Power Delivery (PD) Chargers

Originally, USB-C ports were manufactured for data transfer between devices. The USB Implementers Forum later saw an opportunity to utilize this port for power delivery. This subsequently paved the way for the development of USB-C PD chargers. In this article, we explore all about this charging technology to help you better understand it.

Understanding the USB Power Delivery Protocol

The USB power delivery protocol is an interface technology that opens a communication channel between a device and a USB charger. USB is an acronym that stands for Universal Serial Bus. The term universal here implies that this technology is meant for general use. In other words, multiple devices that have the USB port can use any type of USB charger.

What is a USB-C PD Charger?

USB-C or type-C USB is the latest and among the most advanced types of charger in the market. These chargers can provide a high voltage of up to 240 Watts which is enough to fully charge a laptop in under an hour. Therefore, USB-C PD is equipped with fast-charging technology that ensures a safe transfer of AC to a device.

How does USB-C Power Delivery Work?

Chargers convert alternating current to direct current through the rectification process. This conversion is essential for power storage. In this process, the rectifier or diode in the charger facilitates the conversion. The battery of the device being charged also influences the power delivery by regulating the voltage, battery temperature, and source current.

The basics of fast charging technology

The batteries in devices such as smartphones and laptops have voltage ratings that indicate the rate at which they can be charged. Batteries that support fast charging tend to have high voltage ratings.

Just as implied, fast-charging technology increases the rate of power delivery to a battery significantly. This technology is heavily integrated into modern devices and chargers.

Typically, fast charging is achieved when the voltage or strength of the electric current flowing to the battery is increased. When the voltage is strong, it means that it will increase the amount of electric potential energy flowing, hence filling up the power reserves of the battery.

Features of USB-C (PD) Chargers

Learning about the features of USB-C PD chargers will help you get a deeper sense of these types of chargers. The following are the common features you should expect to see in type-c PD chargers.

Fast-charging technology

The level of output by a charger depends on the specification of the USB port. Currently, USB-C PD input ports have a high specification of data and power transfer. These ports have support for high-voltage flow that enables fast charging without posing any dangers to the device.

Overcurrent and overvoltage protection

Rectifiers found in USB-C PD chargers are responsible for regulating the flow of electric current in devices. Without these diodes, devices would be experiencing the side effects of overcurrent and overvoltage such as explosions.

Multi-port options

Type-C PD chargers can be equipped with multiple output ports to support the charging of multiple devices simultaneously. You will find chargers with up to 5 ports that deliver the same voltage to different devices without failure. Such a design consideration improves the value of the charger to the user.

Compatible with many devices

The increasing saturation of USB-C PD chargers in the market results from the fact that most device manufacturers are including USB-C ports in their devices. Recently, Apple was forced to adopt USB-C for their current generation of smartphones. This compatibility has also increased the value of USB-C PD chargers and made them the standard for chargers worldwide.


Even with all the benefits of USB-C PD chargers, they remain affordable for everyday users. This affordability is partly due to the push for universal charging systems at the same time the low production costs of these chargers.


The longevity of chargers is determined by factors such as plug-in cycles. Still, the components found in its circuitry play a key role. In some studies, USB-C PD chargers have demonstrated the ability to last up to 10 years of frequent use. This classifies them as highly durable in comparison to other chargers.

Difference between USB-C (PD) and regular USB-C cables

The main difference between USB-C PD and USB-C is that USB-C PD is primarily used for charging while USB-C is used for data transfer. However, these cables can be used interchangeably. The only difference is that regular USB-C does not support features like fast charging which are native in USB-C PD cables.

Pros and Cons of USB-C PD Chargers

Along with all the praise, USB-C PD chargers have a few setbacks. Most of the features of these chargers we discussed earlier can be considered benefits. On the other hand, the cons associated with USB-C PD chargers include;

  • Requires high-quality cables to work

  • Counterfeit products

  • Wrong usage can be dangerous

What to Consider when Buying USB-C (PD) Chargers

The following are some of the factors you should consider when purchasing type-C PD chargers.

Power output in watts

Chargers have power output ratings that indicate the number of watts they can produce. Most USB-C PD chargers can output within a range of 20-240W. The higher the Watts, the faster the charger and its capabilities.

Type of device

While USB-C PD chargers have universal compatibility, it is recommended to choose a charger based on the specific type of device. This ties to the wattage rating in the sense that a low-watt charger cannot charge a high-milliampere battery like those used in laptops and iPads.

Manufacturer Warranty

The manufacturer warranty is meant to provide you with assurance that you will be compensated in case the charger has a problem. Therefore, read the warranty terms to ensure that all possible scenarios are covered.

At Andar, our USB-C PD chargers have a 1-year warranty. Also, most of our chargers have an MTBF (mean time between failure) of about 20000 hours. This shows that the chargers are reliable for a long time.

Level of customization

Customization is essential in manufacturing, especially when you intend to resell the chargers. You need to choose manufacturers who are flexible enough to allow you to have a say in the design process of the chargers. At Andar, you get to have a say in the production process of your products.

The level of customization depends on what you want. Since we offer ODM/OEM services, it means that you have full customization control of the chargers. This includes dictating the Watt, number of ports, color, design, and many more aspects and features of the USB-C PD chargers.


USB-C PD chargers are setting the standard for power delivery protocols across various industries. They have innovative features that have not been experienced before. Besides, there is constant research and development of more capable specifications for these chargers. Over time, they could become the actual universal chargers for all devices.
