Attention:

• The power cord between power brick and DC plug will lead to 0.4V~0.6V voltage drop, so we designed the screen displayed voltage was 3.5V~12.5V. Only in this way can your device really get 3V~12V voltage. This is the reason why we advertise the power supply's voltage range is 3V~12V, not 3.5V~12.5V.

Package included

• 1x 24W Universal Power Supply Adapter ; 14x DC Tips ; 1x Reverse polarity converter cable

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 most of the electronics.

Caution:

• The 4cm short black power cord is a reverse polarity converter, not extension wire. It is used to reverse the original polarity of the power supply output port ( reverse the internal positive pole to negative , and the external negative pole to positive). Please confirm the polarity of your devices’ power port before use. If the positive and negative poles are reversed, it will cause short circuit and damage your device.
