USB-C Power Meter with 0.96in IPS Display

The BFKK TC66C is a USB-C power meter that shows voltage, current, capacity, energy, power, equivalent impedance and temperature on a 0.96 inch colour IPS screen. It connects to Android 5.0 or iOS 8.0 devices and PC software via Bluetooth for wireless data logging and control. The tester supports two-way current measurement with 6-digit resolution from 0 V.

Thermals Noise and Power Draw

The unit draws its operating power independently so it can measure low-voltage equipment without an external supply. Its offline storage function caches voltage and current readings when the app or PC software is disconnected, then syncs the data once the link is restored. No active cooling is present, so the device runs silently during normal monitoring tasks.

Sustained Load Behaviour

The meter recognises USB PD, QC 2.0, QC 3.0, Samsung AFC, Huawei FCP and Apple fast-charge protocols, triggering 5 V, 9 V, 12 V and 20 V rails to stress chargers and cables continuously. It captures forward and reverse current throughout extended sessions, letting you verify whether a power source maintains its advertised output under prolonged demand.

Questions about this item

How do I install the BFKK TC66C and connect it to the mobile app?

Insert the tester between the USB-C charger and device; it powers on automatically from 0 V. Enable Bluetooth on your phone running Android 5.0 or iOS 8.0 and pair with the TC66C in the app.

What maintenance or replacement will the TC66C need later?

The unit has no user-replaceable battery or consumable parts; keep the IPS screen clean and ensure the USB-C connectors stay free of debris for reliable contact.

What limit appears first during sustained high-power testing?

Continuous operation is limited by the tester's own thermal rise when measuring 20 V fast-charge loads; allow cooling intervals during extended sessions.
