Product Description

The module has 2 USB protocol charging interfaces and 1 protocol free charging USB interface. Output maximum current of 4A. It has overcurrent protection function. The USB protocol charging interface can automatically identify the type of charging device and handshake with the device through the corresponding USB charging protocol to obtain the maximum charging current, saving charging time while protecting the charging device. Can charge most mobile phones on the market such as Apple and Samsung.

Product Instructions

There are three USB interfaces on the module, with the label "Auto2.4W" indicating that the USB port automatically recognizes the charging device type, and "nolC" indicating that the USB port does not recognize the charging device. Devices that require a protocol for charging, such as the iPhone, can only be charged through the "Auto 2.4W" USB port.

The input voltage range of the module is within DC 5.6-14V, with a maximum output current of 4A. If it exceeds 4A, the module will automatically shut down the output. To protect the modules behind, there is a 2A self recovering fuse at the input end. When the input current exceeds 2A, the fuse becomes high resistance and the output is turned off. Therefore, if the output current is relatively large, it is necessary to increase the input voltage appropriately and reduce the input current. For example, to output 5V 3A, the input voltage should be greater than 7.5V (3A * 5V/2A).

The module has an adjustable potentiometer that can adjust the output voltage (4.8-5.6) V ± 0.3. The adjustable range may vary depending on the input voltage.
