Please read before placing order！
This is the latest upgraded version of adjustable power supply！
Based on hundreds of users feedback, we have made the following improvements:
1. The knob can be adjusted more evenly, and it can reach 7V ~ 8V by rotating 50%.
2. Increase the off gear to turn off the power without pulling the plug.
3. Add a polarity converter cable, which make it compatible with more devices.
4. Correct knob label, "Min" being 3 volts and 12 volts being "Max”.

Kindly note:
Some user complained that voltage will change slightly without adjusting it. In fact, this is normal when your device is working.
Besides, ambient temperature, magnetic field, signal noise will also affect output voltage.
But the change is slight and acceptable. It will not damage your electronics.
