CHARGE! The next generation of wall chargers is getting smaller and better.

Gallium nitride is replacing silicon in at least two new chargers:

It’s not magic: as my colleague Angela Chen explains, GaN is much more efficient, meaning that chargers that use it can be much smaller and waste less energy than ones based on silicon. The biggest obstacle is simply that companies are used to working with silicon, whereas GaN is relatively new; in an ideal world, we’ll probably start to see more products taking advantage of the tech in the near future.

It’s not perfect yet: Anker’s 30W Atom PD 1 struggles to power something as large as a 13-inch MacBook Pro — you can charge it while the computer is sleeping, but while actively running, it’ll still struggle to really keep pace with the power drain (although it’ll work in a pinch). And for anything smaller, like a phone, iPad, Nintendo Switch, headphones, or anything else with USB-C, it’s practically a no-brainer for the $29.99 price.

My 2016-vintage MacBook Pro (since sold off) came with a 61-watt charger, so expecting to charge it — or any laptop — with a 30-watt charger is a bit silly. But that aside, bring on the smaller, faster chargers… faster, please.
