Black rectangular AC adapter with 5.5 by 2.5 mm barrel plug and 3.1 ft cable

BASEUS

BASEUS 12V 5A AC Adapter 100-240V 5.5x2.5mm 3.1ft

SKU CH-DMVX-SG3NM

Converts 100-240 V AC to 12 V DC at up to 5 A with a 5.5 × 2.5 mm plug, 3.1 ft cable and built-in overload, over-voltage, over-temperature and short-circuit protection

  • TypeAC Adapters
  • Delivers up to 60W for demanding 12V devices
  • Works worldwide with 100-240V input voltage range
  • Fits both 5.5x2.5mm and 5.5x2.1mm DC ports
  • 1ft cable plus included female connector adds reach
  • Smart chip guards against overload, over-voltage, over-temperature and short circuits

Universal 12V 5A adapter for low-draw devices

This AC-to-DC adapter delivers a regulated 12V output at up to 5A with a 60W ceiling, accepting 100-240V 50/60Hz mains input worldwide. The 5.5mm x 2.5mm barrel tip also fits 5.5mm x 2.1mm sockets and uses inner-positive polarity, making it a direct replacement for many routers, monitors, LED strips and small appliances that draw 5A or less.

Extra 2.1mm tip extends compatibility

A female 5.5mm x 2.1mm converter is included in the box, so the single 5.5mm x 2.5mm plug covers both common barrel sizes without hunting for a separate adapter. The 3.1ft (95cm) detachable mains cord keeps the wall outlet within easy reach while the brick sits on a desk or floor, and the smart-chip protection suite — overload, over-voltage, over-temperature and short-circuit cut-offs — acts silently unless a fault occurs.

Handles steady loads up to 5A, stops at 60W

Devices rated from 0.5A through 4.5A run continuously within the adapter’s 60W limit, but anything demanding more than 5A or 60W will trigger the protection circuit and shut the unit down. The adapter is not suited for high-current motors, large audio amplifiers or multi-bay drive enclosures that exceed the 5A ceiling, and it cannot power equipment that requires a different voltage or polarity.

Questions about this item

Does the 5.5 x 2.5 mm DC plug wear out and need replacement?

The 5.5 x 2.5 mm barrel connector is a passive part with no moving contacts; it does not wear out under normal use and requires no scheduled replacement.

What limits continuous operation at the full 5 A output?

The adapter is rated for 60 W maximum output; drawing more than 5 A triggers the built-in overload cut-off, which is the first limit reached under sustained load.

How hot or noisy does the unit get when running all day at 12 V 5 A?

The supply has no fan, so it runs silently; heat is dissipated through the case, and the over-temperature cut-off protects the unit if airflow is restricted.
