Free generator wattage calculator. Select your appliances, calculate total watts needed, and get the right generator size recommendation with fuel cost estimate.
Hey Product Hunt! 👋
I built PickMyWatt because I was tired of guessing what size generator I need.
The problem: When shopping for a generator, most people either overpay for way more power than they need, or worse — buy one that can't handle their essential appliances during an outage.
What PickMyWatt does:
- 🔌 100+ appliances with accurate running & starting watts
- 📊 NEC Article 220 compliant calculations (the real standard electricians use)
- 💰 Fuel cost estimation — know what it'll cost to run
- 📸 Share your results — send a snapshot to your electrician or spouse
- ⚡ Starting watts — that surge when motors kick on matters!
Two modes:
1. "I Need a Generator" — select appliances → get the right size recommendation
2. "I Already Have One" — enter your generator watts → see what you can run
It's free, no signup, no BS. Just pick your appliances and get an answer.
Try it out and let me know what you think! What appliances did I miss? 🤔
