BASEUS 24V 5A AC Adapter 5.5mm Plug

SKU CH-5A6R-6YHPK

Converts 100-240 V AC to 24 V DC at up to 5 A with a 5.5 mm plug and built-in overload, over-voltage, over-current, overheat and short-circuit protection

  • TypeAC Adapters
  • Global 100-240 V input works anywhere
  • 24 V 5 A output powers up to 120 W loads
  • 5 mm barrel fits 2.1-2.5 mm centre pins
  • Overload, over-voltage, over-current and thermal cut-offs protect gear
  • Stable 24 V with no spikes at power-on or power-off

What it is

This is a 24 V AC-to-DC switching power supply rated for 5 A maximum output. It accepts a universal AC input from 100 V to 240 V at 50 Hz or 60 Hz. The unit is intended for fixed installations such as LED strips, CCTV cameras, monitors and similar 24 V equipment. It is not a battery charger and must not be used to charge laptops or any device with an internal battery.

Plug fit

The barrel connector measures 5.5 mm outer diameter with an inner diameter between 2.1 mm and 2.5 mm. Polarity is centre positive and sleeve negative; reversing the connection will damage the load. The adapter only fits devices that use this exact plug size and polarity, so buyers with a different jack or reversed polarity cannot use it.

Thermals and noise

Built-in protections include overload, over-voltage, over-current, over-temperature and short-circuit cut-off. The supply delivers a steady 24 V output with no voltage fluctuation during turn-on, operation or turn-off. It is rated for loads up to 120 W and operates silently without a fan in normal use.

  • 5 mm barrel fits 2.1-2.5 mm centre pins

Questions about this item

What does the 5 A rating mean for a device I connect to this adapter?

The adapter can supply up to 5 A at 24 V, so any 24 V device drawing 5 A or less — such as a 500 mA, 1 A, 1.5 A, 2 A, 2.5 A, 3 A, 3.5 A, 4 A, 4.5 A or 5 A load — will operate within its 120 W limit.

What does the 100-240 V 50/60 Hz input actually cover in daily use?

It accepts mains voltages from 100 V to 240 V at either 50 Hz or 60 Hz, letting you plug the unit into standard household outlets worldwide without a separate voltage selector.

Will the 5.5 mm plug fit my equipment?

The DC connector has a 5.5 mm outer diameter and a 2.1–2.5 mm inner diameter with centre-positive polarity, matching the common barrel jack used on many LED strips, CCTV cameras and monitors.
