BASEUS

BASEUS 24V 2A AC Adapter 5.5mm x 2.5mm US Plug

SKU CH-6WBY-83PR6

Converts 100-240 V AC to 24 V DC at up to 2 A with a 5.5 mm x 2.5 mm barrel plug and includes a screw-terminal female connector for LED strips, CCTV cameras or 3D printers

  • TypeAC Adapters
  • Delivers steady 24 V 2 A output for reliable device operation
  • Accepts 100–240 V 50/60 Hz input for worldwide mains compatibility
  • 150 cm (4.6 ft) cable gives flexible placement options
  • 5 mm × 2.5 mm barrel plug with inner-positive polarity fits many 24 V devices
  • Includes screw-terminal female connector for solder-free wiring

Power output and connector

This 24 V 2 A AC adapter delivers up to 48 W through a 5.5 mm by 2.5 mm barrel plug with centre-positive polarity. It accepts 100 V to 240 V input at 50 Hz or 60 Hz and includes a female DC barrel connector for screw-terminal wiring. The unit is intended for 24 V equipment such as LED strips, CCTV cameras and 3D printers.

Thermals and noise

The adapter operates without a fan, so it runs silently in normal use. A 150 cm (4.6 ft) output cord provides placement flexibility while keeping the transformer body away from heat-sensitive surfaces. No active cooling is required for loads within the rated 2 A limit.

Sustained load behaviour

Under continuous operation at the full 2 A rating the supply maintains a stable 24 V DC output. It is designed for devices drawing less than 2 A and is not suitable for charging mobile phones, laptops or MacBooks. The included female connector allows secure, solder-free connections for long-term installations.

Questions about this item

How do I connect the 5.5 mm by 2.5 mm barrel plug to my device, and what wiring mistake do people make?

The plug has a 5.5 mm outer diameter and 2.1–2.5 mm inner diameter with inner positive and outer negative; the included female connector lets you screw wires on without soldering, but reversing the polarity will prevent the device from powering on.

What part of this adapter will wear out first and need replacing?

The 150 cm output cable and the barrel connector see the most flexing; repeated bending near the plug or adapter body can fracture the conductors, so inspect the cord periodically and replace the unit if the jacket cracks or the connection becomes intermittent.

At what load does the adapter hit its limit during continuous use?

The supply is rated for 24 V at 2 A, so any device drawing more than 2 A or 48 W will cause the output voltage to sag or the protection to shut the unit down; keep the connected load below that threshold for stable operation.
