Powering Handheld Devices

Module uses:

1. Connect to the power supply (3-35V), the power indicator light is on, and the module is working normally.

2. Adjust the blue potentiometer knob (usually turn counterclockwise to boost, clockwise to decrease) and use a multimeter to monitor the output voltage until it reaches the required voltage.

Precautions:

1. It is recommended to use a current within 2.5A for long-term work, and add a heat sink (output above 10W); since it is a boost module, in order to ensure stable output, please keep a minimum voltage difference of 1.5V.

Applications:

1. Vehicle regulated power supply, you only need to connect the input end of this module to the car cigarette lighter to supply power, you can adjust the potentiometer, and the output voltage can be adjusted arbitrarily between 5V-30V to charge your mobile phone, MP3, MP4, PSP, etc. Powered by many devices, very simple and convenient.

2. Power supply to electronic equipment. When the equipment needs 5V-35V power supply and the corresponding voltage power supply is in hand, this module can easily adjust the voltage to the required voltage and solve the problem.

3. System working voltage test, you can use this module to debug the working voltage range of various voltage test systems when doing projects, which is very easy and convenient.
