aFe Power USB Tester 2.0 Dual Port PD QC 3.0 Color LED Display

Compact USB power meter for charging diagnostics

The aFe Power USB Tester 2.0 combines a color LED display with dual USB-A and USB-C ports to monitor voltage, current, power and capacity in real time. It supports PD and QC 3.0 fast-charge protocols and auto-identifies the active standard between 3.6 V and 12 V at up to 3 A. One button cycles through seven display modes, making it practical for technicians, DIY builders and anyone verifying charger or cable performance. It does not suit buyers who need logging via PC software or multi-port simultaneous load testing.

Passive monitoring with alarm thresholds

The unit draws operating current from the source under test, rated from 0.03 A to 5.00 A depending on mode, with a maximum discharge power of 35 W. Input voltage range spans 3.5 V to 30 V across supported configurations, and built-in alarms flag over-voltage, under-voltage, over-current and short-circuit conditions. No internal battery or fan is present, so operation is silent and adds negligible load. It does not suit users who require active load control or programmable discharge profiles.

Pocket-sized clamp tool with dual outputs

Weighing 0.041 kg, the tester uses a clamp-style housing that plugs inline between a power source and the device under test. Dual USB 2.0 output ports allow charging and data transfer, though output is limited to charging only when the meter is powered. A long press on the button activates output at 5 V. The form factor fits tight spaces but offers no mounting holes or ruggedised casing. It does not suit installers needing DIN-rail or panel-mount integration.
