USB-C Tester for Charger Diagnostics

The BFKK FNB58 is a 2.0-inch TFT LCD tester that integrates USB-A, Micro-USB and Type-C interfaces. It measures voltage, current, power, resistance, capacity and temperature while identifying fast-charge protocols such as PD2.0, PD3.0, QC2.0, QC3.0, FCP, SCP, AFC, VOOC and Super VOOC.

Before Ordering Check Ports and Cables

Verify that the charger or power bank you intend to test exposes a USB-A, Micro-USB or Type-C port compatible with the tester's three built-in connectors. Ensure the test cable carries the required data lines for protocol negotiation and that the device under test supports one of the listed trigger standards.

Bundled Clip Cable Enables Quick Hook-Up

The included USB clip cable lets you tap into a charging circuit without soldering, while the on-board 16-bit ADC and PD physical chip capture up to 10 switchable data sets. Low-speed waveform sampling runs at 2 to 100 sps and high-speed ripple capture reaches 4 M sps for detailed analysis.

Questions about this item

Does the BFKK FNB58 come with the USB clip cable shown in the listing or must it be purchased separately?

The supplier title confirms the USB clip cable is included with the tester.

Which fast-charging protocols can the FNB58 trigger and monitor automatically?

It supports QC2.0, QC3.0, FCP, SCP, AFC, PD2.0, PD3.0, VOOC, WARP, Super VOOC 1.0, Super VOOC 2.0 and MTK-PE with automatic detection.

What does the 4 M sps sampling rate mean when checking a charger?

It lets the FNB58 capture high-speed ripple on the power line so you can see voltage stability under load.
