Features 1、15W power, 2A current, can be used for router power supply. 2、As a USB charging cable, adjust the charging voltage and maximum charging current arbitrarily (any voltage, with constant current, anti-backflow, to meet the charging of most batteries). 3、As a USB input adjustable desktop power supply, you can adjust the output voltage arbitrarily, limit the current 0-2A (wide input 5~12V, wide output 0.5-30V any adjustment, with short circuit protection, short circuit does not burn). 4、Multiple protection (short circuit, over current, over temperature, over power, over voltage protection, charging anti-backflow protection). 5、Three power supply modes, the actual power supply range is 4-13V. Specification Features: 15W power, 2A current, can be used for router power supply. Three power supply modes, the actual power supply range is 5~12V. Specification: Item Type:Power Supply Module Current: 2A ON indicator: Lights up when the output is turned on, otherwise turned off. CC indicator: Lights up when constant current (current limit is reached), otherwise turns off. Size:8 x 4 x 2cm / 3.15 x 1.57 x 0.79in Package List: 1 x Module Package List
