USB Power Delivery Testers

USB Power Delivery Tester for USB ports and USB chargers

USB Power Delivery Testers are one of the quickest and easiest ways to diagnose and troubleshoot your USB ports and USB chargers.

With the USB Power Delivery Tester, you can:

  • Test the power delivery capability of USB ports, USB chargers, and USB power banks.
  • Check if a USB host is capable of delivering its maximum specified wattage without failing.
  • Detect the wattage a USB charger (wall-wart) claims to support, which in turn controls the charging speed of mobile phones and other USB connected battery devices.
  • Check that voltage levels remain within specification under high load.
  • Measure the exact power usage of USB devices.
  • Use it with the USB loopback tester, to test communication speed, data integrity, and power delivery of USB ports simultaneously.

  • Tests the power delivery capability of USB ports up to 100Watts according to USB Battery Charging 1.2 and USB Power Delivery standards.
  • Tests the power delivery capability of USB chargers (Detects proprietary chargers and adjusts the maximum current accordingly)
  • Negotiates voltage levels with host PD controller chip to switch between different voltage levels.
  • Dissipates 50 watts continuously, and up to 100 watts for short periods.
  • Measure electrical ripple at 1kHz.
  • Measure the capacity of USB power banks and battery packs in mAh.
  • When used in conjunction with the USB loopback tester, tests communication speed, data integrity, and power delivery of USB ports simultaneously.
  • Current can be adjusted with milliamp precision using rotary encoder or via software.
  • Controllable and configurable over USB interface. The API which allows you to change the load, read the current and voltage levels and Update the LCD contents.
  • Built-in protection against overcurrent, over voltage, over temperature and ESD.
  • Isolated USB Monitoring port which protects the monitoring machine.
  • Bootloader which allows updating the firmware in field.
