Direct Replacement for LG 27MK400H-B

This AC-DC adapter is built as a non-OEM replacement for the LG 27MK400H-B 27in Full HD TN monitor. It ships with a mains power cable and a barrel-tip connector sized for that display. The unit is CE, FCC and RoHS certified and includes over-voltage and over-heat protection. It is not suitable for monitors that require a different voltage, tip diameter or polarity.

Worldwide 100-240V AC Input

The charger accepts AC 100-240V at 50-60Hz, allowing use on mains supplies worldwide without a separate voltage selector. Output is DC via the barrel connector; buyers must confirm the required DC voltage and tip dimensions match the original adapter before ordering. The package contains only the adapter and the detachable power cord.

Continuous Operation with Ventilation

Under sustained load the adapter relies on passive cooling and the built-in over-heat protection circuit. The supplier advises keeping the unit in a well-ventilated, low-humidity location during extended use and not placing it on soft surfaces that could block airflow. If abnormal heat or noise appears, discontinue use immediately.

Questions about this item

What does the 100-240V input range mean when I plug this adapter into a wall outlet?

It accepts mains power from 100 to 240 volts at 50 or 60 hertz, so it works worldwide without a voltage converter.

The barrel tip connector — what does it limit in practice?

The barrel tip size must match the LG 27MK400H-B monitor exactly; an incorrect tip will not deliver power.

What physical space does the adapter and its power cable need on a desk?

The brick and included mains cable sit inline between the wall socket and the monitor, requiring only a standard AC outlet and clearance for the barrel plug.
