USB Charger Doctor Voltage and Current Tester Ammeter Blue

The USB Charger Doctor Voltage and Current Tester (Vertical Blue Model) is an essential diagnostic tool designed for makers, students, and hardware engineers to monitor the performance of USB ports, chargers, and power banks. This compact device plug directly into any standard USB Type-A port to measure output voltage and current draw in real-time, helping you quickly identify faulty power adapters, high-resistance cables, or power-hungry USB peripherals.

Perfect for debugging DIY electronics, testing the current consumption of development boards like Arduino or Raspberry Pi, and verifying power bank capacities. Its vertical form factor ensures it fits neatly into closely spaced USB ports without blocking adjacent connections. With no external power source or batteries required, this plug-and-play ammeter is a highly portable and reliable addition to any electronics workbench.

Features:

• Real-Time Monitoring: Alternately displays precise voltage and current readings on a bright LED screen.
• Plug and Play: Powered directly by the USB port under test, requiring no external batteries or power supply.
• Vertical Design: Space-saving vertical orientation prevents blocking of adjacent USB ports on laptops or hubs.
• Wide Compatibility: Works seamlessly with all standard USB Type-A chargers, power banks, and computer ports.
• Durable Casing: Housed in a translucent blue protective shell that allows you to view the internal circuitry while keeping it safe.
