PD power adapter is a power adapter with PD protocol. PD stands for Power Delivery and it means power transmission management in Chinese. PD charging protocol is a power transmission protocol released by USB-IF organization. USB-Power Delivery can enhance the power of type-c interface up to 100W.
USB Power Delivery (USB PD) is one of the mainstream fast charging protocols, which is a rapid charging specification formulated by USB-IF organization. USB PD increases power delivery through USB cables and connectors, and expands the power supply capability of the cable bus in USB applications. This specification can achieve higher voltage and current. The maximum power that can be delivered is 100W, and the direction of power transfer can be changed freely.
In the era of fast charging, the definition of power adapter is no longer as single-function as traditional power adapter. Different customers have different logic requirements for multi-port control, as well as different display and control requirements. For customized functions, they can support various demands of customers.
Currently, there are generally two types of interfaces for PD power adapters , USB A interface and USB C (TYPE-C) interface. From the perspective of functional definition, the core function of PD power adapter is PD fast charging.
PD fast charging is very popular this year because Google released a statement earlier this year that all Android phones in the future must be compatible with PD fast charging and USB interface cannot adjust voltage through non-USB PD protocols. In addition, Chinese Ministry of Industry and Information Technology supports PD fast charging. It seems that PD fast charging is going to unify the market, and all mobile devices can achieve fast charging through PD chargers. GIHONGDA Electronics offers 30W/45W/65W PD power adapters, with obvious advantages including wider charging range and better compatibility. It adopts single-port output, with an output power of 45W, and supports five charging voltages: 5V3A, 9V3A, 12V2.5A, 15V3A, and 20V2.25A, with very strong stability. It has passed UL, CE, PSE, CCC and other certifications.
