BFKK USB 3.0 Tester IPS Colour Display 5.1A 30V 150W Clear

SKU CH-244R-41TDB

USB 3.0 tester with 12,800-pixel IPS colour display measures current, voltage, capacity and power up to 5.1 A, 30 V and 150 W.

  • IPS colour display with 12800 pixels for clear readings
  • Measures up to 5.1 A 30 V 150 W for charger testing
  • Auto-detects fast-charge protocols including QC 2.0 3.0 and Huawei SCP 4.5 V 5 A
  • Power-off memory accumulates capacity across sessions
  • Low 1 mΩ sampling resistance reduces self-consumption for accurate data

USB 3.0 Tester for Charger Analysis

This USB 3.0 tester measures voltage, current, capacity, power and time on a 12,800 pixel IPS colour LCD. The screen rotates for readable viewing at different angles. A sampling chip with 1 milliiohm internal resistance reduces self-consumption to improve measurement reliability. It automatically detects multiple fast-charging protocols including Apple 2.4A, QC2.0, QC3.0, FCP and SCP.

Clear Housing with USB-A Connectors

The transparent case lets you see the internal board while protecting the circuitry during bench or field use. Standard USB-A input and output ports allow inline testing of chargers, cables and power banks without adapters. The wide 5.1A, 30V, 150W range covers most USB-A charging scenarios. Simple one-button operation cycles through the displayed metrics instantly.

Power-Off Memory for Capacity Tests

The power-off memory function retains accumulated capacity data when the unit loses supply. This lets you complete a full power-bank discharge from 100% to 0 over several sessions instead of one continuous run. You can pause and resume long capacity tests without losing the running total, saving time when evaluating high-capacity packs.
