How to use Reserve Polarity Converter Cable?
Checking whether your device is(Inner:”+”, Outer:”-” )or(Inner:”-”, Outer:”+” )
If Inner:”+”, Outer:”-” , it is not necessary to connect reserve polarity cable;
If Inner:”-”, Outer:”+” , please connect the reserve polarity cable when connecting the power supply.
Please Note:
1. Indoor use only.(Not waterproof)
2. DC connector polarity: inside Positive(+), outside Negative(-).
If your device requires output power with reverse polarity, please remember to use the reverse polarity converter cable that we have equipped.
3. Our normal power supply voltage range is 3V~24V. The power cord between the power brick and the DC plug will cause a voltage drop of 0.4V ~ 0.6V, so the screen display voltage is 3.5V~12.5V. In other words, if the voltage required by the equipment you use is 6V, please adjust the screen display to 6.4V~6.6V.
Package included:
- 1 x 72W Power Adapter
- 1 x Reverse Polarity Converter
- 14x DC adapter plugs

Reverse Polarity Converter
We specially added a reverse polarity converter cable, for electronic devices that needs center output negative power supply. Reserve polarity cable expands the application of power supply.

LED Dispaly Voltage
Through the LED voltage display, you can more intuitively know whether the voltage you adjust meets your needs, and more effectively control the power supply.

3-24V Adjustable Voltage
Supply with any voltage between 3~24V, all-in-one multipurpose AC/DC adapter widely used for many 3V~24V 3A small household electronics.

Universal DC port
5.5mm X 2.5mm universal DC port,match with variety of electronic products.

Strong durable tail card
The tail card uses high-quality materials, not easy to break, can be used for a long time.

14x DC adapter plugs
Equipped with multiple connector to meet your various power needs.

Working for Echo Dot, Keyboard, Video, Game USB HUB, Kindle Fire Tablet, Phone, CCTV Camera, Raspberry PI, LED Strip Light, Baby monitor, TV Box, Router, Wifi Receiver, Speaker, ADSL Cat, Console, Serato DJ Controller, Mini Fan, and more 5V electronics devices.
