Understanding Charging Speeds: PD Protocol vs. USB 3.0

In this technology approach world, keeping your device charged is crucial for your daily lifestyle. But most people wonder why some cables charge their devices faster than others. The answer often lies in the charging protocol that the cable uses. Three aspects are crucial to charging a device fast and efficiently: the adapter with a specific wattage, the cable with the correct charging protocol, and the device that can handle the particular charging protocol and speeds. This blog explains the difference between the standard charging protocol that today's devices are capable of: PD and USB 3.0 charging speeds. 

 

What is USB 3.0 Charging?

USB 3.0 primarily refers to the data transfer speeds that offer a level of PD protocol. This protocol, called SuperSpeed USB, provides a data transfer of about 5 Gbps. Regarding charging power, USB 3.0 would deliver up to 4.5W (5V at 900mA). This is an improvement over a normal USB standard, but it is considered slow charging to charge devices like phones and tablets in today's world.  

 

PD protocol, the fast-charging solution

Power Delivery (PD) is a modern, sophisticated charging protocol that allows higher power transfer. Unlike USB 3.0, PD will enable you to charge your devices at the compatible charging speeds the device can handle. It can usually deliver a charging speed of up to 100W. Currently, its technology has extended to 240W as well. This would make it capable of faster charging speeds for most devices, from smartphones, tablets, small devices and even laptops.

 

PD is a game changer.

PD can deliver higher power than USB 3.0 standards, drastically reducing charging time. When the PD cable is connected to devices with PD-enabled protocols, both the device and the cable communicate with each other and deliver the optimal voltage and current for faster and safer charging. This means your devices will only charge if necessary, prevent overcharging, and reduce charging damage. The PD protocol is only implemented in USB-C (e.g., USB-C to USB-C and USB-C to Lightning connectors), making it possible to charge any device universally. 

 

The Key Difference: Purpose and Power

Their main difference lies in their primary purpose and the power they are designed to deliver.

USB 3.0 is a primary data transferring standard designed to deliver adequate power to charge a device. It is suitable for data sync and charging smaller devices like earbuds. 

PD protocol is the charging standard that focuses on fast and efficient charging for all kinds of devices, from small to large, like laptops.

While a USB 3.0 port would deliver some power, it lacks in comparison to the capabilities of a PD protocol. PD-enabled technology is the way to go if you are looking for a fast-charging cable or adapter for your modern devices.
