The PowerPortnerLink is a high-capacity analog power supply unit utilizing a standard 7.4mm barrel connector. It provides a 19.5V/9.23A output, delivering a 180W power ceiling required for professional Thunderbolt docking stations to provide full 130W upstream charging to host laptops. Performance analysis indicates the use of a standard switching power supply topology with integrated over-voltage and thermal shutdown protections.
Technical specifications confirm that without the 180W input, many multi-port docks will throttle upstream power, which can lead to reduced CPU clock speeds and BIOS warnings. The build features a passive cooling chassis and 18AWG copper cabling. Identification of the "Smart" wattage ID is facilitated by a dedicated signal pin in the center of the connector tip.
- Output: 19.5V @ 9.23A (180W).
- Connector: 7.4mm x 5.0mm with signal pin.
- Protection: Thermal shutdown, over-voltage, short-circuit.
Constraints of this hardware include a fixed DC cable and a larger physical footprint compared to GaN-based alternatives. Proper alignment of the center pin is required to ensure the host system correctly identifies the power source wattage.
As a replacement for failing or lost OEM bricks, the PowerPortnerLink 180W provides the necessary amperage to maintain full docking station functionality.
This component is an essential power accessory for the power backup solutions and professional hardware categories.
