🔌 USB-C Power Monitor, Ampere Meter & Charging Diagnostic Tool

PortPulse is a professional USB-C power monitor and ampere meter for Android that shows real-time charging current, battery temperature, and charging behavior with precision data.

Stop guessing whether your charger, cable, or charging port is working correctly. PortPulse lets you measure charging speed, detect cable quality, and monitor power flow in real time.

Designed for power users, hardware testers, and Android enthusiasts.

⚡ Monitor Charging Speed in Real Time

Is your phone charging as fast as it should? Is your USB-C cable actually delivering full power?

PortPulse displays live charging current (mA) and tracks how power changes second-by-second during a charging session. Watch exactly how your device behaves as it fast-charges, thermal throttles, or enters trickle-charge mode.

No estimates. No guessing. Just real data.

📊 Real-Time Ampere Monitoring & Graphs

PortPulse acts as a high-precision ampere meter with live waveform graphing.

Track charging current (mA) in real time

See power fluctuations instantly

Identify fast-charge profile changes

Observe charging slowdowns due to heat or battery protection

Perfect for diagnosing slow charging and testing different chargers.

🔍 USB-C Cable Quality & E-Marker Detection

Not all USB-C cables are equal.

PortPulse identifies:

Standard USB-C cables

3A high-speed cables

5A E-Marker cables

Quickly determine whether a cable supports USB Power Delivery, high-wattage charging, or Thunderbolt-class performance. Eliminate low-quality or charge-only cables from your setup.

🔌 Charger Type & Power Delivery Profiling

Instantly identify your charging source and its capabilities.

PortPulse detects:

USB Power Delivery (PD) chargers

Qualcomm Quick Charge (QC) adapters

Standard USB ports

Power banks and wireless chargers

See the maximum potential charging speed your charger can deliver and whether your device is actually receiving it.

🧠 Charging Stability & Port Health Monitoring

Charging problems often come from unstable connections.

PortPulse monitors connection stability and detects:

Micro-disconnects

Cable wear or internal breaks

Dirty or damaged charging ports

Get early warnings before slow charging becomes hardware failure.

🌡️ Battery Temperature & Thermal Tracking

Heat directly affects charging speed and battery health.

PortPulse monitors battery temperature in:

Celsius (°C)

Fahrenheit (°F)

Watch exactly when heat causes charging current to drop and identify overheating chargers, cables, or wireless pads.
