ICstation mini DC-DC voltage booster module supporting DC 2V-24V input and DC 5V-28V adjustable voltage ouput with high conversion efficiency up to 93%. On-board micro USB power input port, just connected with the common USB power adapter then you can get 9V/12V/15V/18V/24V voltage ideal for DIY power supply.<br><br><b>Specifications:</b><br>Input Voltage: DC 2V-24V <br>Output Voltage: DC 5V-28V <br>Peak Current: 2A <br>Maximum Coversion Efficiency: 93% <br>Maximum Load Power: 7W <br>Board Size: 30 X 17 X 14mm/1.18 X 0.67 X 0.55inch(L*W*H) <br><br><b>Packing:</b><br>1X Micro USB DC Voltage Regulator Board 2V-24V to 5V-28V<br><br><b>-----------------------------❤❤ Warm Prompt ❤❤-----------------------------</b><br>1. This is a boost converter module, so the output voltage should be at least 2V higher than the input voltage.<br>2. When receive the module, please turn the potentiometer clockwise by more than 10 turns before test, for example, rotate the potentiometer with 15 laps in clockwise direction, before power on it.<br>3. Peak current: 2A (1A is recommended for a long time). Cannot select the maximum value of voltage and current as the output at the same time. When the output voltage is increased, the output current is reduced accordingly, and vice versa.<br>4. Please send us an email in case you met problem in using or received defective one, we will take charge of your order and follow up your emails in 12 hours. Thank you!
