How GaN Chargers Are Changing Fast Charging
Same wattage, smaller housing, less heat. Here's why GaN has become the default choice for higher-wattage chargers.
Gallium Nitride (GaN) is a semiconductor material that replaces the silicon traditionally used inside chargers. It conducts electricity more efficiently and generates less heat, which allows a much smaller housing at the same or higher wattage.
Smaller, Cooler, More Powerful
A 65W GaN charger can fit into roughly the footprint that used to be needed for a 30W silicon-based charger. That efficiency gain is also why GaN chargers can safely support dual USB-A + USB-C output at higher combined wattage without overheating.
Why It Matters for Distributors
Customers increasingly compare chargers by physical size as much as wattage — a compact GaN charger reads as premium on a retail shelf even at the same price point as a bulkier alternative. This has made GaN charger suppliers increasingly important partners for distributors upgrading their charger lineup.
SIONIX's 65W GaN A+C dual port charger is designed specifically to take advantage of this — full protocol charging across two ports in a housing roughly a third smaller than equivalent older designs.
