Review: Good Product - Check Female Connector Compatibilty - The adapter worked fine and took the place of the original (defunct one). The only slight setback was that the new adapter's female connector was slightly different than on the old adapter and didn't permit current flow. I simply clipped off the new and spliced in the old. Potential buyers need to somehow check if the new female connector is compatible with the old before purchase if possible, if not at least be prepared to remove the new connector and replace it with old or find a coupling to convert the new to the old.
Review: Perfect power cord for me - I always worry about buying power adapters because of figuring out what volts I needs with my monitors. This adapter I've had for a few months and it is working great! It feels and looks sturdy, it doesn't get really hot and has a pretty long cord length. I say it's worth the price.

## Features

- 【CRITICAL: For 12V/ ≤3A Devices ONLY】-- To ensure proper operation and safety: 1) Your device MUST be 12V DC. 2) Its current draw MUST be 3A or less (Power ≤36W). This is a low-power adapter. Exceeding 3A may lead to failure or damage.
- 【Detailed Power Specs & Use】-- Provides stable DC 12V, Max 3A (3000mA) output from any AC 100-240V outlet. Total cable length 6.7 ft (205cm). Indoor use only. Ideal for routers, LEDs, monitors, and other low-power 12V equipment within the rated capacity.
- 【Plug Design】-- Fit for both 5.5x2.5mm & 5.5x2.1mm plug. This cable terminates with a "standard" 5.5mm OD, 2.5mm ID DC plug, but it's also compatible with DC 5.5x2.1mm socket with the inner center spring contact. (NOTE: Power Supply Polarity: Center or Tip is positive (+), Sleeve is negative(-).
- 【Built-in Power Supply Protection】-- It ensures safe use with over voltage, over current, and over temperature protection to keep all of your mobile devices safe from unexpected surges and spikes. Wide voltage range from 100V to 240V makes it suitable for travel.
- 【Wide Applications】-- 12V 3A Power adapters are in high demand for audio amp boards, portable powered speakers, cable boxes, LED light strips, LCD monitor, wireless routers, CCTV cameras, DC motors, 3D printers, computer projects, HUB, Switches, audio/ video power supply, and Arduino controllers to provide a safe and stable power supply for your creation.
