As answered by people managing CampPowerCalc and Stackfix.
CampPowerCalc's answer
Because it's built by someone who actually camps off-grid. The appliance library comes from real gear lists (not marketing specs), the output shows watt-hours per device (not just a total), and you can tweak individual items to see how adding a 12V fridge or swapping LED bulbs changes your battery needs. No signup, no app download, no email capture — open the page, run the numbers, done.
CampPowerCalc's answer
Most camping power calculators give you a single "you need X Ah" number and stop there. CampPowerCalc breaks it down by appliance — fridge, lights, phone charger, heater — so you can see exactly what's drawing power, adjust the list, and understand the tradeoffs. It supports 6 languages, runs entirely in your browser with no server upload, and is built from real van life and RV camper feedback rather than generic assumptions.
CampPowerCalc's answer
Van lifers, RV owners, overlanders, and car campers who are planning or upgrading their off-grid electrical setup. Also useful for pre-purchase research — figuring out whether a 100Ah battery or 200W solar panel actually covers their real load before buying gear.
CampPowerCalc's answer
I built it after spending weeks reading Reddit threads (r/vandwellers, r/overlanding) and forum posts where people kept asking the same question: "How big a battery do I really need?" Every answer was either a spreadsheet link or a vague "it depends." CampPowerCalc turns that spreadsheet into an interactive tool that walks through your actual appliance list and shows the math.
CampPowerCalc's answer
Vanilla JavaScript with a static frontend hosted on Cloudflare Pages. No backend, no database, no user accounts — all calculation happens locally in the browser. The site uses next-intl for 6-language support (English, German, French, Spanish, Japanese, Chinese) with hand-written native translations.
