Product Description

The 19V 2.1A LG Adaptor is a high-quality switching mode power supply (SMPS) specifically engineered for LG LED and LCD monitors. Providing a regulated 19V DC output, this adapter ensures the stable operation of sensitive display circuitry, preventing screen flickering and extending the lifespan of the backlight. Its compact, lightweight design makes it an ideal replacement for lost or damaged original LG power bricks. The unit is built with high-grade components to offer low ripple and noise, ensuring that your monitor receives clean power for optimal visual performance.

Key Features

  • LG-Specific DC Connector: Features the standard 6.5mm x 4.4mm barrel plug with a dedicated central pin, ensuring a secure and reliable connection to LG display ports.

  • Universal Input Compatibility: Supports a wide input range of 100V to 240V AC, making it suitable for use across different regional power standards.

  • Advanced Safety Circuitry: Equipped with built-in protection against over-voltage (OVP), over-current (OCP), and short-circuits (SCP) to safeguard your equipment.

  • High Energy Efficiency: Designed to meet modern energy-saving standards, operating with minimal heat generation even during long hours of use.

  • Durable Build Quality: Constructed with a flame-retardant outer shell and reinforced strain relief at both ends of the DC cable to prevent fraying.

Technical Details

  • Polarity: Center Positive (+), Outer Sleeve Negative (-).

  • Certification: CE / RoHS compliant (variant dependent).

  • Enclosure: Impact-resistant ABS plastic.

Prototyping and Engineering Tips from Robogears

  • Confirm the Center Pin: CRITICAL: LG and Samsung monitors often use very similar-looking 6.5mm plugs. Always check if your monitor's power port has a small pin in the center. If the port is "hollow," this adapter will not fit.

  • Wattage Compatibility: This is a 40W adapter (19V×2.1A). You can safely use this to replace an LG adapter rated at 19V 1.3A or 1.7A, as the monitor will only draw the current it requires. Do not use it to replace a 3.42A or higher-rated adapter, as this will lead to overheating and failure.

  • Voltage Sensitivity: Display electronics are precision-tuned for 19V. Avoid using generic "Multi-voltage" adapters set to 18V or 20V, as even a 1V difference can trigger a protective shutdown or damage the internal LED driver of your LG screen.

  • Heat Dissipation: While this SMPS runs relatively cool, avoid covering it with papers or placing it on carpets during use. Maintaining airflow around the plastic casing is essential for the longevity of the internal electrolytic capacitors.

  • DIY Use Case: If you are repurposing this for a DIY project (like a high-power 19V soldering iron or a laptop-style workstation), the center-pin design requires careful soldering if you are replacing the jack. The center pin is the Positive (+) lead.

Package Includes

  • 1 x 19V 2.1A LG Adaptor

Disclaimer: For indoor use only. Do not expose to water, moisture, or extreme heat. Always verify that your monitor's power requirements (usually listed on the back label) match 19V DC before connecting the adapter. Disconnect from the mains during lightning storms to prevent surge damage.
