BASEUS 24V 0.5A AC Adapter 100-240V 5.5x2.5mm Plug

SKU CH-7WZZ-BEXH9

Converts 100-240V AC to 24V 0.5A DC with a 5.5x2.5mm plug compatible with 2.1mm devices

  • TypeAC Adapters
  • Works worldwide with 100-240V AC input
  • Delivers stable 24V 0.5A DC output up to 12W
  • Fits 5.5x2.5mm and 5.5x2.1mm plugs with centre-positive polarity
  • Protected by overcurrent, overvoltage, overload and short-circuit safeguards
  • Flame-retardant shell rated to 1382 and certified FCC, CE, RoHS, CCC

Purpose-built 24 V power supply

This BASEUS adapter converts AC 100-240 V mains to a regulated DC 24 V 0.5 A output with a 5.5 × 2.5 mm barrel plug that also fits 5.5 × 2.1 mm sockets. Polarity is centre-positive. The unit delivers up to 12 W and includes over-current, over-voltage, overload and short-circuit protection inside a flame-retardant shell rated to 1382 °C.

Suits low-power 24 V gear, not laptops

It powers LED strip lights, essential-oil diffusers, USB hubs, small speakers, wireless routers, mini fountains and 24 V cameras that draw 500 mA or less. Devices needing more than 12 W, a different voltage, a higher current rating or a proprietary connector cannot use this adapter.

Deciding spec is the 5.5 × 2.5 mm centre-positive

Match the device’s required jack size and polarity exactly; the tip must be 5.5 mm outer diameter, 2.5 mm inner diameter with positive on the centre pin. If the equipment specifies a different barrel dimension or centre-negative wiring, this unit will not connect correctly.

Questions about this item

How can I confirm the adapter is delivering 24 V 0.5 A after I plug it in?

Measure the DC plug with a multimeter set to DC volts; you should read 24 V with the centre pin positive, and the connected device should power on without the adapter overheating.

What comes in the box and is a mains lead included?

The adapter ships with a fixed 3 ft power cord and a 5.5 mm × 2.5 mm DC plug that also fits 5.5 mm × 2.1 mm sockets; no separate mains lead is required.

Should I choose this 24 V 0.5 A model or a higher-amperage version for my 12 W LED strip?

This 12 W unit matches strips drawing up to 500 mA; pick a higher-amperage model only if your load exceeds 0.5 A.
