Mirror's hardware is concrete: 160W total output, with all four USB-C ports supporting up to 140W. Any socket can offer the top tier, while actual power is scheduled from the total budget — no main port and no second-class port. Two laptops share power without dropping out, and roughly 200W of peak headroom covers sudden surges.
How small a body holds all that power? At 31.94 cm³ per port and 1.08 W/cm³, it is the world's smallest five-port integration. Assembled, it is a desktop power stack with two rear outlets; detach the main body and it becomes a travel charger that grips the wall and won't fall — a bar-shaped center of gravity over the plug, ready to drop into a backpack.
The details hold up too: 93.7% efficiency and ripple as low as 18mV, far under the 200mVp-p national standard. Safety margins run wide: physical limits of 105°C, 32A, and 1000V, 64.2% voltage-tolerance headroom, a 1/8 current load ratio, and a 105°C anti-saturation transformer.
