The case for GaN

Silicon has carried power electronics for fifty years, but it wastes energy as heat at high switching frequencies. Gallium nitride switches faster with lower losses, which means smaller transformers, less heatsink, and a brick you can actually pack.

The Cell 100W runs four ports off a single GaN stage. The payoff is not just size — it is efficiency, so more of the wall energy reaches your laptop and less warms the room.

Smaller, cooler, faster. That is the whole case.
