The knob can be adjusted more evenly, and it can reach 7V ~ 8V by rotating 50%. <br> 2. Increase the off gear to turn off the power without pulling the plug.<br> 3. Add a polarity converter cable, which make it compatible with more devices. <br> 4. Correct knob label, "Min" being 3 volts and 12 volts being "Max”. <br> <br><b>Kindly note:</b><br> Some user complained that voltage will change slightly without adjusting it. In fact, this is normal when your device is working. <br> Besides, ambient temperature, magnetic field, signal noise will also affect output voltage. <br> But the change is slight and acceptable. It will not damage your electronics. <br>
