BASEUS 5V 3A AC Adapter 100-240V 5.5x2.5mm Plug 15W

SKU CH-N0HS-ZKJ92

Converts 100-240V AC to 5V DC at up to 3A with a 5.5x2.5mm plug for LED strips, cameras and routers

  • TypeAC Adapters
  • Universal 100-240V input powers devices worldwide
  • 5V 3A output delivers 15W for LED strips and cameras
  • Screw-terminal DC connector enables wiring without soldering
  • 5×2.5mm plug fits 2.1mm centre-pin devices
  • Operate below 80% load for reliable long-term use

5 V 3 A desktop power supply

This AC-to-DC adapter converts 100 V to 240 V mains input into a regulated 5 V output at up to 3 A and 15 W. It is built for devices that draw 3 A or less, such as LED strips, CCTV cameras, routers and small projects. The 5.5 mm × 2.5 mm barrel plug also fits 2.1 mm centre pins. It is not a battery charger and must not be used with laptops or other battery-powered gear.

Thermals noise and power draw

The unit runs from standard wall power and delivers a steady 5 V DC rail for loads up to the 3 A maximum. Operating below 80 % of the rated current keeps temperatures low and avoids overload. No fan is present, so operation is silent. Input voltage auto-ranges across the 100 V to 240 V band for worldwide use.

Screw-terminal DC connector

A female DC jack is included so wires can be secured without soldering. Polarity is centre-positive and barrel-negative; reversing it will prevent the connected equipment from working. The adapter suits WS2811, WS2812B, SK6812, APA102 and similar 5 V pixel strips as well as security cameras and network devices. It cannot charge laptops or any device with an internal battery.

Questions about this item

How do I connect wires to the female DC connector on this 5.5x2.5mm adapter without soldering?

The adapter includes a female DC connector with screw terminals; insert stripped wires and tighten the screws, ensuring the inner positive and outer negative polarity matches your device.

What ongoing check should I perform on this 15W supply to keep it reliable?

Periodically verify the screw terminals remain tight and the plug pins are clean, as loose connections or oxidised contacts can cause voltage drop under load.

What is the first limit reached when this 5V 3A adapter runs continuously at high load?

The 3 A maximum output current is the hard limit; exceeding it triggers overload protection and shuts the unit down.
