What Is a GaN (gallium nitride) Charger, and Why Should You Buy One? (www.reviewgeek.com)

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.

We have laptops with two chargers for a while but those are usually very high end machines with top of the line CPUs and GPUs or desktop parts. I guess this technology will make it more convenient.
The framework laptop will have different gpu modules, for most of them (4050, 60 and 70) 125W will be more than enough.
