Voltage converter Extralink OPIP-300W 12V 300W pure sine, aluminium housing, active cooling

The Extralink OPIP-300W is a 12 V automotive voltage converter (inverter) that delivers 300 W of pure sine AC output in an aluminium housing with active cooling. Designed to convert 12 V DC from a battery into 230 V AC, this inverter enables operation of sensitive electronics and small household appliances in vehicles, boats, recreational vehicles or remote locations without mains power. A built-in USB port provides an additional convenient output for charging USB devices.

Advantages

The pure sine output provides a clean and stable 230 V AC waveform closely matching mains electricity, making it suitable for sensitive electronics and devices that require reliable AC power. The aluminium housing offers physical durability and heat dissipation, while the active cooling system helps maintain optimal operating temperature under continuous or variable loads. The compact single-unit form factor is suitable for mobile and space-constrained installations.

Suitable for

• Powering laptops, televisions, and audio equipment in cars, RVs and boats
• Running small kitchen appliances and lighting in camp or off-grid setups
• Charging phones, tablets and other USB devices via the integrated USB output
• Providing temporary backup power for low-power equipment during outages

Key specifications

• Input voltage: 12 V DC
• Continuous output power: 300 W (pure sine wave)
• Output voltage: 230 V AC
• Output waveform: Pure sine wave suitable for sensitive electronics
• Cooling: Active cooling (fan-assisted)
• Enclosure material: Aluminium housing for improved heat dissipation
• Additional outputs: USB port for charging USB-compatible devices

How to use

Connect the inverter to a properly charged 12 V DC battery using the recommended cabling and polarity, ensuring secure and correct terminal connections. Place the unit on a stable, well-ventilated surface to allow airflow for the active cooling fan and avoid covering ventilation openings. Plug the AC appliance into the 230 V outlet on the inverter or use the USB port for USB-powered devices. Observe the inverter’s power limits and do not exceed the 300 W continuous rating; allow the unit to cool between heavy loads if necessary.

Usage recommendations

Before each use, verify battery state-of-charge and cable connections, and ensure the total connected AC load does not exceed the inverter's continuous power rating. For prolonged or high-load operation, provide adequate ventilation for the aluminium housing and avoid placement near flammable materials. Use the pure sine output for sensitive electronics and follow device manufacturer guidance for safe operation.
