Direct-plug wall adapters introduce mechanical stress to AC sockets and dictate poor cable routing on crowded production sets. The SIIG 100W 4-Port USB-C Charging Station (AC-PW1N11-S1) solves this physical limitation via AC decoupling. By utilizing a dedicated IEC AC input cable, it allows you to mount the power hub securely to a sound cart rack or desktop, isolating heavy DC cabling from the wall outlet.
Electronically, this hub is built around an advanced power management chipset designed for strict protocol adherence. It fully supports Programmable Power Supply (PPS) and USB-C Power Delivery (PD 3.0). This allows the charger to execute dynamic voltage scaling, communicating directly with the internal Battery Management System (BMS) of your Audioroot eSMART batteries via the TINY-C charger. By delivering current at precisely negotiated voltage steps, it drastically reduces thermal waste and prevents cell degradation during rapid charging cycles.
The internal load-balancing architecture automatically routes the 100W maximum output based on hardware handshake protocols. When operating solo, a single USB-C port can push a full 100W (20V/5A) to sustain high-draw DSP applications on a MacBook Pro. When fully populated, the IC intelligently splits the load (e.g., 65W on C1, 30W on C2, plus 5V/A distribution on standard ports) ensuring stable, noise-free current to all connected peripherals.
Technical Specifications & Advantages:
-
Intelligent AC Decoupling: Uses an external AC cable (desktop form factor) to prevent mechanical “wall-wart sag” and allow for secure rig or cart mounting.
-
Precision PPS Negotiation: Crucial for the Audioroot eSMART TINY-C. The PPS protocol supports dynamic, real-time voltage and current stepping to optimize charging efficiency and protect Li-Ion cell chemistry.
-
Dynamic Output Matrix:
-
USB-C1 / C2 Output: 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A (Max 100W single-port).
-
USB-A1 / A2 Output (QC 3.0): 3.6-6.5V/3A, 6.5-9V/2A, 9-12V/1.5A (Max 18W single-port).
-
Smart Load Balancing: Automatically shifts wattage based on device draw (e.g., 65W + 30W for dual Type-C utilization).
-
-
Comprehensive Protection Suite: Integrated fail-safes including Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP) to safeguard thousands of euros of connected audio hardware.
-
Global Compatibility: 100-240V AC wide-range input voltage, ensuring flawless operation on international documentary shoots regardless of local grid fluctuations.
