Measure charging current, power, voltage & temperature with Charger Tester.
Charger Tester is a simple visual charging monitor that helps you understand how your phone is charging in real time. Monitor charging current, voltage, power and battery temperature from one dashboard. Follow battery level, charging speed and status, view live power changes, and review previous charging sessions. ⚡ LIVE CHARGING MONITOR See key charging information while your phone is charging: • Charging current in mA/A • Charging voltage in V • Charging power in W • Battery temperature • Battery level • Charging status • Charging source • Charging speed 🔌 CHARGER TESTER Connect your charger and watch live charging measurements. Compare different charger and cable combinations on the same phone to understand charging performance. Readings can vary depending on your phone, charger, cable, battery level, temperature and Android system. ⚡ CHARGING SPEED MONITOR Check how charging power changes in real time. Charger Tester uses available device data to help you understand slow or faster charging without relying only on the charging icon. 📊 LIVE POWER GRAPH Watch charging power change over time with the live power graph. See recent charging activity and identify changes in performance during a charging session. 🔋 BATTERY LEVEL & TIME TO FULL Track your battery level while charging. When supported by the device, the app can show an estimated time to full. This estimate can change as charging conditions change and should be treated as a guide. 🌡️ BATTERY TEMPERATURE Monitor battery temperature while charging. Temperature can change with charging power, battery level, device usage, ambient conditions and other factors. 📈 CHARGING HISTORY Record and review previous charging sessions with useful statistics: • Charging duration • Battery level gained • Average and maximum power • Average and maximum current • Average voltage • Maximum temperature • Power over time Open individual sessions for detailed charging performance, graphs, battery gain and statistics. 📱 SIMPLE VISUAL DASHBOARD Charger Tester keeps important charging information easy to understand. The main dashboard brings power, current, voltage, temperature, battery level and charging status together without unnecessary menus. Use it to: • Check charging current • Monitor charging power • Check charging voltage • Monitor battery temperature • Understand slow charging • Check charging speed • Compare charging sessions • Review charging history • Monitor battery level • Understand charger and cable performance ⚠️ ABOUT CHARGING MEASUREMENTS Charging values are provided by your Android device and can vary between phone models. Readings may be affected by the device, Android version, charger, USB cable, battery level, battery condition, temperature, screen activity, background processes and other system factors. Displayed charging power is calculated from available device measurements. It should be treated as a practical indication of charging behaviour, not a laboratory-grade measurement or direct measurement of power from the wall outlet. Charging power may decrease as the battery approaches full because phones can adjust charging behaviour as battery level increases. For better comparisons, test different chargers or cables on the same device under similar battery and usage conditions. 🔋 UNDERSTAND YOUR CHARGING BETTER A charging icon shows that your phone is charging. Charger Tester gives you a clearer view of the charging information available from your device. Track current. Check voltage. Watch power. Monitor temperature. Follow battery level. Review charging sessions. Whether you are checking a new charger, comparing charging setups, investigating slow charging or simply interested in your phone's charging behaviour, Charger Tester helps you understand charging performance in one visual monitor. Charger Tester — measure every charge.
