When you’re on the hunt for a new USB power adaptor, you may come across a few options with gallium nitride (GaN) technology. These charging bricks tend to be a bit expensive. But due to their reduced size and increased charging ability, a GaN charger may be your ideal purchase. It could even help you save money in the long run.
Most USB chargers use silicon semiconductors. Gallium nitride (GaN) is simply a power-efficient alternative to silicon. It allows a charger to achieve small size without a reduction in charging speed or thermal performance. A GaN charger is ideal for travelling or powering several high-wattage devices, such as laptops.
With more and more laptops charging through USB-C, and more phones making use of ultra-fast charging, you’ll start to notice that the silicon based chargers can get really hot during charging these devices.
Instead of buying a large silicon-based charger that only has two ports (with a shared throughput), you can buy a GaN charger with four, five, or even six high-speed charging ports.

I wonder what would be the difference in environmental footprint between the two types of chargers. According to this article it seems okay-ish compared to classical chargers, but more sources would be needed for me to form an opinion on the matter.
Anyhow, these new chargers look neat
Well one’s giving off lots of heat is wasted energy, so the GaN are likely more efficient.
