ER QuickCalc: Launch Day & What's Next

Launch Day

ER QuickCalc is officially live. The goal has always been simple: give Genshin Impact players a fast, accurate way to figure out Energy Recharge requirements for any team composition — without needing spreadsheets or complex math.

This version was rebuilt from the ground up — faster, more accurate, and easier to use. The original site served its purpose, but we knew we could do better. So we rewrote everything: the engine, the interface, the data pipeline. Same goal, better foundation.

Since launch, the tool has expanded well beyond its initial release. Here's where things stand now.

What You Can Do

• Team ER Calculator — Select any 4 characters, set their role (Driver, Battery, Burst Support, etc.), and get per-character ER recommendations based on real game data.
• Equipment Configurator — Choose weapons, artifacts, and constellations. The engine calculates particle generation, energy conversion, and passive effects.
• Auto-Fill Equipment — Let the tool suggest equipment based on your team's energy needs.
• Share Results — Generate a unique URL to save or share your build. No account needed.
• 120+ Characters Supported — Each with structured skill, burst, passive, and constellation data.

How It Works

Everything runs in your browser. Select your team, equip your characters, and the calculation engine simulates energy generation, particle collection, and conversion to give you ER recommendations per character. No data is sent to any server. Your team builds exist only in your URL.

What We've Built Since Launch

• Comparison mode — side-by-side ER analysis for different builds
• Additional artifact sets — more sets covered, including recent additions
• Mobile UI improvements — responsive layout optimized for smaller screens
• Session restore — pick up where you left off without re-entering your team

What's Next

• Deeper constellation-aware calculations
• More team composition presets
• Further performance and accuracy improvements

Keep the Feedback Coming

The tool keeps getting better because of what you tell us. If you spot a calculation that doesn't match your in-game experience, open an issue or reach out on Discord — every report matters.

No accounts. No data collection. No tracking. Just a calculator that works.
