## Long description

Unit UT658DUAL is a compact USB-A and USB-C tester that monitors charging parameters and cumulative capacity during charging. The device measures voltage and current in real time and records accumulated capacity from 0 to 99,999 mAh. Supporting Quick Charge 3.0 and 4.0, the tester provides clear live readings to evaluate chargers, power banks and cables and to diagnose charging issues or verify power delivery performance.
Advantages
The UT658DUAL combines dual-port compatibility with continuous measurement of voltage, current and accumulated mAh, making it suitable for both USB-A and USB-C environments. Its wide capacity range up to 99,999 mAh allows long-term testing and cumulative tracking. Support for Quick Charge 3.0 and 4.0 ensures that fast charging protocols are detected and displayed. The compact design enables convenient inline testing without bulky setups, while the real-time numeric display helps quickly identify voltage drops, current fluctuations and charging interruptions.
Suitable for
 Testing wall chargers and USB power adapters
 Evaluating power banks and capacity verification
 Checking USB-A and USB-C cables for voltage drop or poor contact
 Diagnosing intermittent charging or slow-charge issues on devices
 Verifying Quick Charge 3.0 and 4.0 negotiation and delivery
Key specifications
 Connector types: USB-A input/output and USB-C input/output compatible
 Measured parameters: voltage (V), current (A) and accumulated capacity (mAh)
 Capacity measurement range: 0–99,999 mAh
 Support for Quick Charge protocols: QC 3.0 and QC 4.0
 Real-time numeric display for live monitoring
 Compact inline form factor for easy insertion between charger and device
How to use
Connect the UT658DUAL between the charger and the device or power bank so that the USB-A or USB-C ports align with the corresponding cables. The tester will power on and display live voltage and current values automatically when a load is present. To measure cumulative capacity, allow the device to remain connected for the desired charging period; the accumulated mAh counter will increase as current is delivered. Observe the numeric display to check for sudden drops or irregularities during the charging cycle. For Quick Charge detection, use a compatible charger and device; the tester will show negotiated fast-charge parameters while charging is active.
Usage recommendations
Use short, reliable cables and ensure secure connections when measuring to reduce measurement error. When testing power banks for full capacity, perform a complete charge–discharge cycle at a moderate load and record the accumulated mAh. Avoid exposing the tester to moisture or excessive heat and disconnect when not in use to prevent unintended battery drain on the tested device.
