UNI-T UT658 USB Charger & Cable Tester – Digital Voltage, Current & Capacity Meter (3V–9V, 0A–3A) in Pakistan

Overview

When troubleshooting slow-charging smartphones, testing DIY power banks, or checking the quality of questionable USB cables, guessing output performance leads to wasted time and underperforming gear. Standard chargers and cables often drop voltage under load without warning. The UNI-T UT658 USB Tester provides a portable, precision diagnostic solution, designed to monitor USB charger voltage, operating current, charging capacity, and cable drop performance instantly.

Key Features

• Simultaneous Multi-Parameter Display: Clear digital screen displays output voltage, operating current, accumulated capacity (mAh), and time concurrently.

• Compact Plug-and-Play Design: Inline USB interface connects easily between your charger and charging cable without requiring external power sources.

• Data Storage & Retention: Features built-in storage capacity to retain test results even after power is disconnected.

• Cable Quality Evaluation: Helps detect substandard or high-resistance charging cables by monitoring voltage drop under active load.
