Three conditions that must be met to select a power adapter:
1. Adapter connector(5.5x2.5mm DC Jack) matching with the device.
2. The output voltage(DC 12V) of the adapter must be the same as the rated input voltage of the load (mobile device), or within the acceptable voltage range of the load (mobile device), otherwise it may burn the load (mobile device).
3. The output current (4A) of the power adapter should be equal to or greater than the current of the load (mobile device) to provide sufficient power.

Application:
Commonly used for LED signage, CCTV security surveillance camera, security DVR, lighting, car, boat, monitors, printers, sensors, external hard drives, audio mixing and recording equipment, and more.

Package include:
1 X 12V 4A AC Power Adapter with US Plug
1 X 5.5mm x 2.1mm Female connector(Gift).

Output: DC 12V 4A / 4000mA 48W, 3.6 Ft Cable, DC interface size: 5.5mm x 2.5mm (and compatible with 5.5mm x 2.1mm)
It perfect replacement for 2A / 2.5A / 3A / 3.5A as amperage isnt forced. (If your previous Adaptor was less than 4A then this will be a perfect replacement as amperage is NOT Forced)
Third generation smart IC chip features: Short Circuit Protection, Overload Protection, Over Voltage Protection to protect your device
Free 5.5x2.1mm female connector easier for led strip or camera installation, save time and more securer cable connection.
