Wefomey 3V-24V 3A Universal Power Supply 72W Adjustable 2-Pin AC/DC Adapter

This is a universal power supply fits almost all DC input sockets. It can supply with any voltage between 3~24V,such as 3V 4V 4.5V 5V 5.5V 6V 9V 12V 14V 15V 19V 20V 24V, etc and any amp less than 3A, such as 300mA, 500mA,1A, 1.5A, 2A, 2.5A, 3A. The rating power is equal to or less than 72 Watt. -Alligator clip test lead is perfect for electrical testing such as electronic experiments, bread boarding, circuit testing, battery test, electric appliance test, digital product power connection test, prototyping, and troubleshooting.-The 17cm 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.Instructions on how to choose a suitable adapter:1. Check Voltage: Please find the spec label of your device and check the working voltage. It should be among 3V~24V DC, not lower than 3V or higher than 24V DC. Otherwise, your device will not work or be damaged.2. Check Current: Check the max current your device will draw. It should be equal to or less than 3A, such as 1A, 1.5A, 2A, 2.5A, 3A. Otherwise, your device won’t work well and the PS will be damaged very soon.3. Check Plugs: Check the power input port of your device. The PS is equipped with 14 pcs frequently-used DC tips. Please confirm wether it fits for your device before buy. If you can 't confirm, please measure it with a ruler.4. Check Original PS If you have a original power supply for reference, their output voltage, plug size, polarity should be the same . If our PS’s current is equal to or higher than original one’s, then our PS will work with your device.
