As answered by people managing Codewars and CampPowerCalc.
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.
