KWS Type-C Charging Tester DC 4–30V 0–12A Digital Voltmeter Current Meter Ammeter Power Bank Phone Charger Indicator

Take full diagnostic control over your USB Type-C charging speeds, power banks, wall adapters, and cable health with the KWS Type-C Digital Charging Tester. Designed for tech enthusiasts, repair technicians, electronics hobbyists, and everyday smartphone users, this multi-functional inline power meter measures DC voltage (4–30V), real-time current (0–12A), active wattage, cumulative capacity (mAh), energy throughput (mWh), and internal load resistance. Equipped with bidirectional Type-C pass-through architecture, it supports modern fast-charging protocols including Power Delivery (PD 3.0/2.0), Quick Charge (QC 4.0/3.0/2.0), and PPS without throttling charging speeds. The high-definition color LCD screen clearly displays multiple power metrics simultaneously, helping you identify faulty charging cables, verify power bank capacity, and protect delicate devices from dangerous over-voltage conditions.

Key Features

• Real-Time Multi-Parameter Monitoring: Displays DC Voltage (4–30V), Amperage (0–12A), Wattage (W), Capacity (mAh), Energy (mWh), and Resistance ($\Omega$) simultaneously.

• Fast-Charging Protocol Support: Pass-through design fully supports USB Power Delivery (PD 3.0), Quick Charge (QC 4.0/3.0), and high-current fast charging up to 12 Amps.

• Bi-Directional Current Sensing: Measures power flow in either direction, allowing seamless testing of wall chargers, power banks, laptops, and smartphones.

• Vivid Color LCD Display: Clear, multi-color digital screen provides high contrast visibility from multiple viewing angles.

• Internal Data Memory Function: Saves cumulative capacity (mAh) and time tracking even after being unplugged, making total power bank capacity testing effortless.

Why Choose Our KWS Type-C Charging Tester

Charging smartphones, laptops, and power banks with unverified cables or cheap wall adapters can result in extremely slow charge times, excessive heat, or battery degradation. Basic USB meters lack Type-C high-current capability and choke fast-charging protocols down to standard speeds. This KWS Type-C tester combines 12A high-current handling, wide 4–30V range detection, full fast-charge protocol compatibility, and vivid multi-metric LCD readouts—giving your hardware testing, battery diagnostics, and mobile tech maintenance an instant professional upgrade.
