Samlex 800W Modified Sine Wave Inverter - 12V

The Samlex 800W Modified Sine Wave Inverter – 12V converts 12-volt DC power to 115-volt AC output at 60 Hz, making it essential equipment for marine vessels, RVs, and off-grid applications where shore power isn't available. This compact 800-watt inverter delivers reliable power conversion for critical onboard systems, navigation equipment, and cabin electronics without the bulk of heavier alternatives.

Built with low-interference modified sine wave technology, this Samlex inverter provides clean enough power for most marine electronics and appliances. The unit features two standard three-prong outlets for AC devices, plus a dedicated USB charging port with 5VDC output at 2.1A for charging phones and tablets. A load-controlled cooling fan automatically activates only when needed, reducing noise during low-demand periods. Universal protection circuits guard against thermal overload, battery discharge, short circuits, and surge conditions, ensuring both the inverter and connected equipment stay protected in unpredictable marine environments.

Weighing just 4.1 pounds with compact dimensions of 11 x 3 x 12 inches, this inverter fits tight spaces typical of smaller fishing boats, sailboats, and RV cabins. The low battery input alarm alerts operators before voltage drops too far, preventing system damage from deep discharge. Weekend anglers running fish finders and sounder systems benefit from stable 12V DC to 115V AC conversion, while cruising sailors appreciate the dedicated USB charging alongside traditional outlets for mixed modern electronics.

Samlex America's SAM Series represents proven marine inverter design, and the 800W capacity handles moderate power demands without requiring a full battery bank upgrade. This inverter sits in the practical middle ground—enough output for cabin lighting, small refrigeration units, and entertainment systems, while remaining manageable in terms of battery draw and installation complexity on smaller vessels.
