Had forgotten about that. I worked at the Rockwell science center at that time and went into their clean room once and had to put on a “bunny suit” to work on some computers inside it. They had a gallium chip product of some sort.
My dad worked there too. :)

Apple’s recommended charger for a 13inch MBP is a 61W adapter, for the 15 inch is an 87W and for the 16 inch is a 96W. Although you can use an under-specced adapter it probably won’t be enough to power and charge the system while fully using the CPU, GPU, and screen.
Basically you just repeated what I just said... I am actually considering buying 30W one for it's portability. But then again I am not a YouTube influencer that occasionally games and cuts videos (you know, the person that Apple designs it's computers nowadays for).
I develop software in Apple's programming language using Apple's frameworks and Apple's own IDE, and power usage is through the roof. 50W while typing (and auto-complete is doing it's job) and 80W while building.
I think it's odd and quite rude that you dismiss anyone who has higher computing than just typing some basic text and browsing the web to be "a YouTube influencer". If all you need is the computing power of an Eee PC then yeah, I don't think you are Apple's target market.

If it's a good quality charger it shouldn't be feeding the battery enough power to impact its lifetime.
While charging circuits are much smarter now, and the difference might be minimal, you want lower charging currents to minimize the amount of damage that is done to the materials in the battery. It is universal that higher charge rates cause more damage to the crystal structure that holds the lithium ions.
Not seeing UL or CSA approval numbers on those. That's important for switching power supplies, especially small ones. A switching power supply is always a few milliseconds from being a short circuit across the input. And FETs fail in the ON state. That's why those things are inherently fire risks and need protection circuitry. Really tiny ones make it worse; if they fail, there's not much space to dissipate heat befo…
If I built a new house today I’d wire 12 volts DC in addition to 110VAC. Safe for kids and fewer unsightly wall warts.

US plug prongs can usually survive being bent and re-bent a number of times. It's quite quite common for people to manage to bend the prongs on their vacuum cleaner dozens of times. Those pull more amps than almost anything else you plug in regularly, and they do just fine. Just go slow.
I've been known to twist them with a pair of pliers into the shape required to plug into Australian sockets (like this: \ / ), then twist them back again. Works fine if there is no earth pin.
I mean, since this thread doesn't seem too picky about fire safety anyways... ;)

I recommend the RavPower 61W GaN over Innergie. The Innergie is smaller, but it is 3x the cost and, in my experience, less reliable and less ergonomic. I purchased the Innergie after a previous travel charger failed. Loved it at first, but started experiencing issues pretty quickly. The first issue I encountered was that the plug would fold in frequently while I was trying to plug into outlet. Over the course of a co…
Anyone have a good recommendation for a wall charger similar to RavPower mentioned in parent comment but with EU plug? Additionally, is there a good charger with EU plug that I can use to charge both my MacBook Air 2018 (USB-C) and my iPhone X with at the same time?
