BASEUS 12V 5A AC Adapter 5.5x2.5mm

SKU CH-816G-S4CVT

A 12V 5A AC adapter with 100-240V input, 5.5x2.5mm jack compatible with 5.5x2.1mm, and overload, over-voltage, thermal and short-circuit protection

  • TypeAC Adapters
  • Delivers stable 12V power with automatic overload, over-voltage, thermal and short-circuit protection
  • Accepts 100-240V input at 50/60Hz for worldwide mains compatibility
  • Supplies up to 5A (60W max) and safely powers any device drawing less current
  • 5×2.5mm barrel plug also fits 5.5×2.1mm sockets for flexible connections
  • Runs silently at low temperature with no voltage spikes at power-on or power-off

Power Supply for 12V Devices

This AC-to-DC adapter converts 100 to 240 volt mains input into a stable 12 volt output rated at 5 amps and up to 60 watts. It features a 5.5 by 2.5 millimetre barrel plug that also fits 5.5 by 2.1 millimetre sockets. Built-in protections include overload, over-voltage, thermal and short-circuit cut-offs. The unit runs silently at low temperature with no voltage fluctuations during power transitions.

Suitable Uses and Limitations

It suits 12 volt LED strips such as 5050 and 3528 types, security cameras, DVR and NVR systems, ADSL hubs, audio and video equipment and 3D printers drawing up to 5 amps. It is not a laptop charger and will not power laptops or computer screens. Buyers needing higher voltage, higher current or a different connector should look at alternative supplies. Polarity must be centre-positive on the target device.

Capacity and Headroom

The adapter delivers any current up to 5000 milliamps, so loads of 1000, 2000, 3000 or 4000 milliamps run with comfortable headroom. At the full 5 amp rating the 60 watt limit is reached, leaving no margin for sustained peaks. Voltage remains steady from switch-on through operation to switch-off, protecting connected electronics from transients.

Questions about this item

What input voltage range must my mains supply provide for this 12 V 5 A adapter to operate?

The adapter accepts 100 V to 240 V at 50 Hz or 60 Hz, so any standard household supply within that range will work.

Will the 5.5 mm × 2.5 mm barrel plug fit my existing device that uses a 5.5 mm × 2.1 mm centre pin?

Yes, the jack is compatible with both 2.5 mm and 2.1 mm centre pins, so it will connect securely to your device.

How can I verify the adapter is delivering stable 12 V output after I connect it?

The unit maintains consistent voltage with no fluctuations at power-on, during operation or at power-off, protecting connected equipment.
