Do PD USB chargers support Samsung's fast charging standard?

In today's fast - paced world, the need for quick and efficient charging solutions has become more crucial than ever. As a leading PD USB charger supplier, I often encounter questions from customers about whether our chargers support Samsung's fast - charging standards. In this blog, we'll delve into the technical details to provide a comprehensive answer.

Understanding PD and Samsung's Fast - Charging Standards

Power Delivery (PD)

Power Delivery is a fast - charging standard developed by the USB Implementers Forum (USB - IF). It allows for higher power transfer over USB connections, with capabilities ranging from 10W to 100W or more. PD chargers can negotiate power levels with connected devices, adjusting the voltage and current to provide the optimal charging speed. This flexibility makes PD chargers suitable for a wide range of devices, including laptops, tablets, and smartphones.

Samsung's Fast - Charging Standards

Samsung has developed several fast - charging technologies over the years, such as Adaptive Fast Charging (AFC) and Super Fast Charging. Adaptive Fast Charging typically supports up to 15W of power, while Super Fast Charging can deliver up to 25W or even 45W in some of the latest models. These technologies are designed to charge Samsung smartphones at a much faster rate compared to standard charging methods.

Compatibility of PD USB Chargers with Samsung's Fast - Charging Standards

Voltage and Current Requirements

One of the key factors in determining charger compatibility is the voltage and current requirements of the device. Samsung's fast - charging standards often require specific voltage and current combinations. For example, Super Fast Charging may operate at 5V/5A or 4.5V/5.6A. PD chargers, on the other hand, support a variety of voltage levels (5V, 9V, 12V, 15V, 20V) and can adjust the current accordingly.

Some PD chargers are capable of outputting the voltage and current levels required by Samsung's fast - charging standards. However, it's important to note that the device also needs to support the negotiation of these power levels. Modern Samsung smartphones are generally equipped with advanced charging chips that can communicate with PD chargers and request the appropriate power.

Charging Protocols

Another aspect of compatibility is the charging protocol. PD is a different protocol from Samsung's AFC and Super Fast Charging. While many Samsung devices can support multiple charging protocols, there may be some limitations. For instance, a PD charger may not be able to provide the exact same charging speed as a Samsung - branded fast charger that uses the native AFC or Super Fast Charging protocol.

However, many PD chargers today support multiple protocols, including PPS (Programmable Power Supply), which can be more flexible in meeting the power requirements of different devices. Our 40W Super Fast Charger is a great example. It supports a wide range of output voltages and currents, and with PPS support, it can potentially offer fast charging speeds for Samsung devices.

Case Studies and Real - World Testing

Testing with Different Samsung Devices

We conducted a series of tests with various Samsung smartphones, including the Galaxy S21, S22, and Note 20. We used our GaN 45W PPS Fast Charging charger and compared the charging times with a Samsung - branded Super Fast Charger.

In most cases, our PD charger was able to charge the Samsung devices at a comparable speed. For example, when charging the Galaxy S22 from 0% to 50%, the PD charger took approximately 25 minutes, while the Samsung - branded charger took around 22 minutes. This shows that our PD chargers can provide a fast - charging experience that is very close to the native Samsung fast - charging solution.

Charging in Different Scenarios

We also tested the chargers in different scenarios, such as charging while the device was in use or in standby mode. In both cases, the PD charger was able to maintain a relatively fast charging speed. When the device was in use, the charging speed was slightly reduced, but it was still significantly faster than standard charging.

Advantages of Using PD USB Chargers for Samsung Devices

Versatility

One of the main advantages of using a PD USB charger for Samsung devices is its versatility. A PD charger can be used to charge not only Samsung smartphones but also other devices such as laptops, tablets, and wireless earbuds. This means that you only need to carry one charger for all your devices, which is very convenient, especially when traveling.

Efficiency

PD chargers are generally more efficient in power transfer compared to some traditional chargers. They can adjust the power output according to the device's needs, which reduces energy waste and heat generation. This not only helps to charge the device faster but also prolongs the battery life of the device.
