Cable & Charge Tester: USB-C

Is your charging cable slow, damaged, or charge-only? Cable & Charge Tester helps you check your USB cables and chargers in seconds.
- REAL-TIME CHARGING TEST • Measure live wattage (W), charging current (mA), voltage (V), and battery temperature (°C). • 10-second benchmark test for accurate average power readings. • Automatic protocol detection (USB Power Delivery, Quick Charge, High Current). • Clear verdict rating: Faulty, Slow, Good, or Fast.
- CABLE RESISTANCE METER • Built-in resistance meter (mΩ) to detect weak, worn-out, or low-quality wire cores. • Visual gauge showing cable efficiency from low resistance (excellent) to high resistance (poor).
- DATA & OTG CABLE CHECK • Identify charge-only cables instantly when connected to a computer. • View active USB mode and detect attached USB OTG devices (flash drives, keyboards, peripherals).
- HISTORY & COMPARISON • Save test results with custom cable names to keep track of your best cables. • Compare any 2 cables side-by-side to easily find the fastest charger and cable combination. • Export test reports as text summaries.
- PRIVACY FIRST & MODERN DESIGN • 100% Local Storage: All test data stays strictly on your device. • Material 3 UI with automatic Dark Theme and AMOLED Pure Black mode for OLED screens.
Note: Charging speed depends on your phone model, charger output, and cable quality. For best results, compare different cables using the exact same charger.
