Hey hunters! 👋 I built CampPowerCalc after sizing my own Sprinter van electrical system. Every calculator I found was either too simplistic (just multiply watts × hours) or tried to sell me a solar kit. So I made one that uses real appliance data, factors in inverter loss (~15%), and adds a 20% safety buffer — the same math I used for my own build. It's completely free. No signup, no email capture, no affiliate links. Just the numbers you need to spec your battery bank and solar panels with confidence. Would love feedback from anyone doing a van/RV build! What's your biggest pain point with power planning?
