Show PH: I built a free, real-time EV Towing Range Calculator (no ads)

Hi Product Hunt! 👋

Towing a caravan or trailer with an EV is a massive headache because aerodynamic drag can slash your range by over 50%. Standard route planners don't let you easily estimate this on the fly.

To solve this, I built a fast, interactive web assistant:

🔗 https://elektroauto-2wja.vercel.app/ (supports English, just toggle the flag in the top right!)

Key features:

• Dynamic Physics: Recalculates range instantly as you drag sliders for speed, trailer type, and temperature.

• Weight Warning: Alerts you if your trailer exceeds your specific EV's legal towing limit.

• Pull-Through Charger Finder: Instantly searches Google Maps for EV stations designed for long car+trailer setups (so you don't have to unhitch!).

It's completely free, mobile-optimized, and made out of pure passion for EVs.

I would love to get your feedback on the UI/UX and features. What do you think of the calculations? What cars or features should I add next?

Thanks for checking it out! 🚀
