Stop guessing. Measure your charging. Charger Watt & Charging Speed Tester is a focused charging diagnostic utility for Android. It turns the charging information available from your device into clear, practical measurements so you can understand what your phone is receiving. CHECK CHARGING POWER IN REAL-TIME See the key charging values available during a charging session: • Watts / charging power • Charging current in mA or amps • Voltage in volts • Battery level • Charging status • Fast-charging information when exposed by your device TEST YOUR CHARGER AND CABLE Run a charging speed test to check how different charging setups perform. Test a charger, test a charging cable, and compare results instead of relying only on the charger's advertised rating. UNDERSTAND SLOW CHARGING Phone charging slowly? Use the available charging data to investigate what is happening. Check charging watts, current, voltage, and charging status to get a clearer picture of your current setup. You can also check fast charging status when your device exposes it. COMPARE CHARGING SETUPS Benchmark your chargers and cables with saved charging test results. Compare chargers and compare cable performance across setups, then use the numbers to make practical decisions when testing accessories. CLEAR DATA, NOT CONFUSING JARGON The app is designed for everyday Android users, while still providing useful measurements for charging enthusiasts. If you are looking for an ampere meter, watt meter, or charging monitor, the app presents the available charging data in a focused, understandable way. WHAT THE READINGS MEAN Charging power can be calculated from available voltage and current readings. Where Android or your device does not provide a value, the information is shown as unavailable rather than presented as an unsupported value. TRANSPARENT ABOUT DEVICE LIMITATIONS Charging measurements can vary between Android devices because available charging data depends on device hardware and operating-system APIs. This app displays the charging information made available by your device. Actual power delivery can vary with hardware, cable quality, charger compatibility, and phone temperature. NO ACCOUNT REQUIRED Use the core charging diagnostic utility without an account or backend dependency. Core operation is designed to be useful offline where the required device data is available. WHY USE CHARGER WATT & CHARGING SPEED TESTER? • Check your charging speed in real-time. • See watts, current, and voltage together. • Investigate slow or unexpected charging. • Test chargers and charging cables. • Benchmark and compare charging setups. • Understand fast-charging status when your device exposes it. • Use clear measurements without unnecessary complexity. Stop guessing. Measure your charging. --- Source: https://storetally.com/android/com.v4tech.charging_tester As of 2026-11-15, from the StoreTally census.
