About This Launch
CampPowerCalc offers free energy-planning tools for camping and RV travel. It sizes a battery bank, solar array and inverter from your appliance loads and hours of use. It also has tools for CPAP battery life, fridge backup runtime, alternator charging time and portable power station sizing, and covers 50+ camping scenarios.
The site runs in the browser, is mobile friendly and comes in six languages: English, Deutsch, Francais, Espanol, Japanese and Chinese. No paid tier is mentioned. The site has privacy, terms and contact pages.
Why I Built This
The goal was to make campervan and RV power planning easier to approach before a trip. Battery, solar and inverter sizing can feel confusing when each appliance has a different wattage and daily runtime.
