Watts of Charger gives you instant real-time measurements of your phone's charging wattage, voltage, and current — in Numeric or Gauge display mode.
A lightweight, ad-supported tool that instantly reveals your charger's true performance — your way.
See your charger's power output the moment you plug in. No setup, no calibration — just plug and read.
Switch between a clean Numeric view (large W/V/mA numbers) and a visual Gauge view with animated speedometer needles.
In Gauge mode, the app records your session's Low and High values live — perfect for spotting charger inconsistency.
The app automatically detects when you connect or disconnect your charger and updates readings in real-time.
We don't collect personal data. Only standard ad identifiers via AdMob. Your data stays yours.
No premium tier, no in-app purchases, no paywalls. The full app experience is free with ads.
Switch between Numeric and Gauge mode, then click to simulate what happens when you connect your charger.
Launch Watts of Charger. You'll see "No Charger" flashing — it's ready to measure.
Plug your cable in. The app detects power flow instantly and starts live measurements.
Read Numeric mode for clean numbers, or switch to Gauge mode for animated speedometer needles with L:/H: tracking.
Use the H: (High) reading in Gauge mode to find which charger delivers the most wattage!
