eMagTech 4Pcs Mini DC Booster Converter Module 3.7V 5V to 12V Boost Step up 10W Output Adjustable Voltage Regulator 8V 9V Power Supply

Input voltage range: 3V~5.5V. The input voltage must be lower than the set output voltage. The output voltage can be set to 5V/8V/9V/12V, with a default output capacity of 12V. When inputted with a 3.6V battery, it can output 5V 1.5A, 8V 1A, 9V 1A, 12V 0.8A. When inputted with 5V, it can output 8V 1.2A, 9V 1.2A, 12V 1A. When outputted with the default 12V, the LED indicator consumes about 1mA of current (the input current is about 3mA) If the indicator is turned off, the input current is
