## Summary description

The Extralink OPIM-300W is a universal car voltage converter with a 12V input and 300W output. It features a metallic aluminum housing, active cooling, and is designed for reliable power supply in vehicles.

## Long description

The Extralink OPIM-300W voltage converter transforms 12V DC battery power into 230V AC, enabling the use of household appliances from a vehicle or other off-grid locations. Designed for use in cars, campervans, boats and remote sites, this inverter provides continuous 300W output with up to 1200W peak power and includes a USB output for charging USB devices. The unit features a metallic aluminium housing and active cooling for reliable operation.
Advantages
This modified sine wave inverter offers a cost-effective way to power TVs, refrigerators, lighting, laptops and mobile phones where mains electricity is not available. The model supplies a stable continuous power of 300W with short-term peak capacity up to 1200W, and its USB port allows direct charging of small electronic devices. The compact metallic body and built-in cooling enhance durability during vehicle and off-grid use.
Suitable for
Powering household appliances in a car, campervan or caravan
Providing electricity on boats and allotments
Off-grid systems and temporary backup power during outages
Charging phones, tablets and other USB devices

How to use
Connect the inverter to a charged 12V battery following the manufacturer’s polarity markings and secure connections. Plug household devices into the 230V AC outlet or use the USB port for compatible devices. Observe the continuous power limit of 300W; avoid running appliances with inductive motors (for example certain central heating pumps or high-power motors) because the modified sine wave output may not be suitable for such equipment. Ensure proper ventilation and keep the unit clear of obstructions to allow active cooling to operate effectively.
Usage recommendations
Use the Extralink OPIM-300W for low- to medium-power resistive and electronic loads such as lighting, TVs, laptops and phone chargers. For sensitive electronics or devices with induction motors, consider a pure sine wave inverter. Regularly check cable connections and battery state to prevent voltage drops and ensure reliable performance.
