Portable outdoor energy storage power supply has multiple output modes, AC 220V output socket, QC3.0 USB-A interface, PD USB-C interface, DC output interface, car charging output interface and other commonly used daily interfaces. Now I will let me introduce the differences and uses of these interfaces.

    AC interface: 

    AC is alternating current, refers to the current between the size and direction at any time, the running average value in a period is zero. The AC wave form is usually a sinusoidal curve.alternating current can transmit power effectively. But there are actually other waveforms, such as triangular waves, square waves. The mains used in life is 220V AC with a sinusoidal waveform. AC output interface is the use of 220V plug.

    DC interface: 

    DC refers to the direct current, generally commonly used 3V, 5V, 9V, 12V and other common voltage, battery and charger is the most typical, the general charger output is about 5V, the general digital device charging is the interface!

    Type-C interface:

     type c interface is a mainstream USB interface form, the full name is USB Type-C. It is smaller than both Type-A and Type-B, and can be applied to both PC (main device) and external devices (from devices, such as mobile phones). USB Type-C has four pairs of TX / RX scores, two pairs of USBD + / D-, one pair of SBU, two CC, plus four VBUS and four ground lines.

    USB interface: 

    In the past, many USB chargers and most previous computer USB ports provided a charging current between 0.5A and 1A. Charging the handheld device through this USB port usually feels slower. Charging the handheld device with a 2A output port is much faster. Many computers now offer high-current USB ports, so they can be charged quickly.

    PD joggle:

    The meaning of pd charging includes the following three points:

    1. Pd charging is USB-Powerdelivery (USBPD), which is one of the main rapid charging protocols at this stage.

    2. pd charging improves power engineering transportation through USB cable and RF connector, and     expands the power distribution capacity of cable system bus in USB applications.

    3. The standard transportation efficiency can reach up to 100 watts, which can arbitrarily change the transmission direction of power engineering.

    The relationship between pd charging and Type-C charging

    Some people often put the USBPD together with the Type-C, and even call the Type-C charging head the PD charging head. The USBPD and Type-C are actually two different things. The USBPD is a fast-charging protocol, and the Type-C is a new interface specification.

    By default, the Type-C socket setting is larger for 5V / 3A, but enables greater power after maintaining the USBPD protocol for the above 100W.

    Therefore, the USBPD protocol will be applicable to many facilities with easy access to Type-C sockets.

    I hope the above content can help you, outdoor power interface later with the development of the equipment, there will be a variety of new interfaces. You can choose the outdoor power supply according to your actual needs.
