The tester uses a new generation of four semi-dual-loop integral conversion integrated circuits, with precise bandgap reference, range accuracy, high precision, stable and reliable performance, and high anti-interference capability.

High temperature resistance can be used to measure power supplies, USB interfaces, mobile phone chargers, USB drives, and other USB-powered products.

It can easily measure the operating current and output voltage of USB ports and equipment.

Small in size, requiring no power supply or other auxiliary equipment, the plug-and-play functionality also detects standard USB charger output voltage and current, making it suitable for factories, laboratories, and individual users.

USB-powered devices can be used to measure air, voltage loads, and the operating voltage and current of USB terminal equipment.
