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.

The biggest difference for me was the noise. Intel mbp fans spinning as soon as you open more than one application, going turbo if you compile anything and slowing down in the summer because of the heat.

The only time I heard my M1 Mac fans is when I left the poor thing in direct sunlight outside

yeah kinda makes you wonder why even bother with the pros, just get the airs

[–] Orygin@sh.itjust.works 2 points 1 year ago (1 children)

I would Guess the air cannot sustain the performance as well as the pro. The battery is way bigger afaik Doing 16+h on a single battery charge is insane

Funny thing is that all the video reviewers review what they know, specifically "editing and rendering video content for their channel".

The majority of users won't even come close to the power usage that those guys require, demand and talk about.

Personally I do a lot of dev work but have never really run into thermal or performance problems on my MBP, and I suspect I'll be fine on MBA as well.
