## What is RV 12V Voltage Drop Planner?

RV 12V Voltage Drop Planner helps you size wiring for 12V circuits with quick, practical calculations. Enter cable length, current, and wire size, then instantly see estimated voltage drop and percentage loss.
Use Imperial (AWG/ft) or Metric (mm²/m) modes for your workflow. The app is built for RV electrical planning, including battery lines, solar runs, lighting circuits, and accessory loads.
With a clean form-based interface and fast results, you can reduce wiring guesswork, improve system efficiency, and avoid common low-voltage issues before installation.
