Power cable length: 7.7ft / 236cm Ensure that its output port size matches the size of your device's power input port. If you are unable to confirm, please let us know for assistance. This product is an AC to DC adapter, not charger. 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. Only in this way can your device really get 3V~24V voltage. This is the reason why we advertise the power supply's voltage range is 3V~24V, not 3.5V~24.5V. The 4cm short black power cord is a reverse polarity converter, not extension wire. 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. 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. 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 . 𝐈𝐧𝐩𝐮𝐭 𝐚𝐧𝐝 𝐎𝐮𝐭𝐩𝐮𝐭: Input: AC 100~240V, 50/60Hz ; Output: DC 3~24V Adjustable, Max 3A 72W ; 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. LCD display will show the output voltage, in case that wrong voltage regulation damage your device. 𝐔𝐩𝐠𝐫𝐚𝐝𝐞𝐝 𝐕𝐞𝐫𝐬𝐢𝐨𝐧 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 13V ~ 14V 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，doubles its range of application. You can screw wires onto it easily, perfect for DIY projects. For indoor use only. 𝐒𝐚𝐟𝐞𝐭𝐲 𝐏𝐫𝐨𝐭𝐞𝐜𝐭𝐢𝐨𝐧 𝐒𝐲𝐬𝐭𝐞𝐦𝐬: Built-in multiple safety protection systems. We focus on producing premium quality and safety power adapters. No noise, no spontaneous combustion, no explosion, no fire hazard, safe to use. 6ft long power cable makes it convenient to use. 𝐊𝐢𝐧𝐝𝐥𝐲 𝐍𝐨𝐭𝐞 𝐚𝐧𝐝 𝐖𝐨𝐫𝐫𝐲-𝐟𝐫𝐞𝐞 𝐒𝐡𝐨𝐩𝐩𝐢𝐧𝐠: Please choose correct voltage before plug it to your device. We recommend to use less than 80% of the full load. We always stand behind our products. If there is any issue, please feel free to contact us.
