12. High-quality USB port
13. Output voltage indicator (RED)
14. Small size, Compact Size
15. Input with reverse polarity protection diode, will not damage when input connect incorrectly
16. Ultra-low static current, 0.85 mA only. Do not need to add switch when connected to the car battery, can be connected to car cigarette lighter cable or ACC power supply cable

Precautions:

1. please enhance heat dissipation when fully used for load output(i.e. 5V@3A with 24V Input).
2. For the ideal case (i.e. 5V@2A output with 12V Input) it does not need to enhance heat dissipation.

Note: The Module has Output short circuit protection, but please do not a short circuit for a long time to avoid damage due to overheating.

Note: This module is not suitable for running a DC motor,  as the module is not able to handle the high current requirement of a DC motor but it can run a small DC Toy motor, whose current requirement is less than 100milli amp.
