Extralink OPIP-300W Voltage Converter with Pure Sine Wave. The Extralink OPIP-300W voltage converter is a device that converts the output voltage of a battery (direct current, DC) into 230V alternating current (AC). 230V AC is the type of electricity provided by utility companies to power standard household appliances such as televisions, refrigerators, radios, lighting, or for charging laptops and mobile phones.

If you already have a charged battery, connecting an inverter allows you to operate household appliances in areas without access to the power grid; for example, in a motorhome, caravan, boat, garden shed, or other remote locations. Inverters are also ideal for off-grid systems and emergency power systems in the event of power outages.

This is a pure sine wave inverter, which means that the 230V AC output voltage follows a smooth sine wave harmonically and is almost identical to the normal power grid. Pure sine is much better than square wave or modified sine wave for operating devices.

Additionally, the inverter features a USB port for powering USB-compatible devices (e.g., phones, tablets, laptops, MP3 players, etc.).
