Description
Wondering if your new charger is delivering maximum power? Or if a bad USB cable is charging your phone slowly? Ampere Speed is a precision charging speed meter, battery current tracker, and real-time power telemetry tool.
Whether you want to test a charger, compare USB Type-C charging cables, check wireless charging speed, or monitor long-term battery health, Ampere Speed provides precise milliampere (mA) current data and actionable battery insights.
FEATURES & POWER METRICS
• Live Charging Speed Meter: Measure real-time charging current (in mA / Amperes), wattage (Watts), voltage (V), and battery temperature (°C / °F). • Charger & Cable Tester: Instantly classify your charging speed status (Fast, Standard, Slow) to identify slow cables and faulty adapters. • Detailed Charging Session Logs: Keep a complete history of every charge cycle, including peak current, average mA, charging duration, and thermal stress. • Battery Health Monitor: Track your system battery parameters to know when your device battery needs servicing or replacement. • 20-80% Battery Guard: Track battery level progress and follow the recommended 20-80% charge rule to minimize battery degradation. • Thermal & Temperature Alerts: Get notified when battery temperature rises above safe levels (40°C / 104°F) during charging sessions. • Export Charging History (CSV): Easily export your detailed charging telemetry to a CSV file for advanced battery diagnostics.
WHY TEST YOUR CHARGING WITH AMPERE SPEED?
Unlike basic battery widgets, Ampere Speed reads directly from your device's power sensors. It measures the active electrical current flow to show you how much power your battery is receiving or discharging under load.
USE CASES FOR EVERYDAY TESTING: 1. Test USB Cables & Adapters: Find out which USB-C cable charges your phone most efficiently. 2. Check Wireless Charging: Verify if your Qi wireless charging pad or magnetic charger is performing as expected. 3. Compare Power Banks: Test portable battery packs to verify their actual output power. 4. Detect Background Battery Drain: Monitor discharge current (mA) when unplugged to spot power-hungry apps.
TIPS FOR EXTENDING BATTERY LIFESPAN: • Avoid Excessive Heat: Avoid heavy gaming or streaming while charging to prevent thermal stress. • Follow the 20-80% Rule: Keeping your charge level between 20% and 80% reduces battery cell tension. • Use Certified Accessories: Stable current flow prevents voltage spikes and protects your device.
