POWER-Z (ChargerLAB) SINK240

SINK240

A bare-PCB USB-C trigger and breakout board that requests any USB PD3.1 voltage profile (SPR and EPR up to 48 V, 240 W) or PPS mode from a PD source and presents it on Type-C and screw-down VBUS/GND terminals for test loads.

Check before buying. A trigger/breakout board only: no display and no voltage, current or power readout; verification needs a separate meter or electronic load

See the recorded specification
Connectors

The trap behind the watts

A live wattage isn’t a PD-profile list.

PDOs describe offered power profiles. E-markers describe declared cable capability. Neither is a file-transfer benchmark. Protocol analysis and long logs may need separate host software.

Maker specifications, not our own measurements. Read the exact model’s manual before use.

    Model: KM003C

    A full USB power meter and protocol analyzer with a color display, made by the same brand family; a different kind of product, not a bare trigger board.

    Buyers who need voltage, current and protocol readout rather than a trigger/breakout board.

    View POWER-Z KM003C

Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • SINK240 has no screen: anyone wanting voltage/current readings from the same device needs a POWER-Z meter such as KM003C instead.
  • SINK240 ships as a bare board; no case, cables or load are included.

Why people pick it

  • Triggers every USB PD3.1 profile including EPR 28/36/48 V up to 240 W, so one small board exercises any PD source a maker publishes
  • Handles PPS negotiation across four ranges (3.3-21 V) for fine-grained source testing
  • Eleven labeled LEDs plus a single button make the negotiated profile readable at a glance without a display or PC
  • Type-C out plus VBUS/GND wire-loop terminals give an easy breakout for electronic loads and bench wiring
  • Compact 54 x 38 mm single-sided board with a 60 V input tolerance, per the maker

Know before you buy

  • A trigger/breakout board only: no display and no voltage, current or power readout; verification needs a separate meter or electronic load
  • Bare PCB with no enclosure, so it is a bench tool rather than a carry-anywhere tester
  • The AVS indicator LED is reserved and the maker states AVS is unusable at present
  • Profiles can only be stepped through one button press at a time; there is no way to jump straight to a chosen PDO
