About
A USB-C-only (no USB-A) four-port charger built around PowerIQ 3.0. The primary port hits 100W solo; C2 caps at 60W and C3/C4 are hardware-locked to 20W each regardless of overall load. Two ports active splits evenly at 60W+60W; all four active settles at 50W+30W+20W+20W, summing exactly to the 120W ceiling.

Confirmed with
- Notebook (generic)
Confirmed via a real user powering a MacBook Air from one of its ports (65W). The charger lacks Intelligent Power Allocation — fixed resistor combinations mean occupying all four ports drops the primary C1 port to 50W, and the unit has no physical grounding pin, which some users report as a faint tingling sensation on metal laptop chassis.
