VEVOR RV Power Converter 80A 120V to 12V SBC-80A

Purpose and Compatibility

This VEVOR RV power converter changes 120V AC shore power into a stable 12V DC supply rated at 80 amps. It serves owners of motorhomes, travel trailers or campers who need to run 12V lighting, appliances and entertainment systems while simultaneously charging the house battery bank. The unit accepts both lead-acid and LiFePO4 chemistries, so it fits existing installations and future lithium upgrades without hardware changes. Buyers who require 24V output or a built-in inverter for AC loads will need a different product.

Thermal Noise and Power Draw

The converter delivers a maximum of 1160 watts at 14.5 volts and 80 amps, with a tolerance of ±20 watts. Ground resistance stays below 300 milliohms when measured at 12 volts and 25 amps, indicating low internal losses during typical charging currents. Multi-stage smart charging automatically tapers current as the battery approaches full state of charge, which reduces heat dissipation and acoustic noise during the absorption and float phases. No fan specifications or decibel ratings are supplied by the manufacturer.

Connections and Mounting Implications

The chassis measures 10.24 inches wide, providing a reference point for cabinet or bulkhead clearance planning. Four replacement fuses are included in the package, simplifying field maintenance if an over-current event occurs. Selectable fixed-voltage modes at 13.0V, 14.6V and 16.5V allow manual tuning for specialised loads or equalisation routines. Input wiring must accommodate 120V AC at 60 Hz, while the DC output terminals should be sized for up to 80 amps continuous current.
