that's mostly because American domestic outlets are the worst in the world.

Do you have an example you'd hold up as the ideal or best case outlet?

There's the one true plug system, IEC 60906-1:

It's also a fascinating example of standards proliferation (https://xkcd.com/927/).

And then there’s this thing which is smaller than either and 60W https://www.amazon.com/dp/B07GBYVF4Q/ref=cm_sw_r_cp_api_i_Fu...

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?

For your bedroom you'd really want an old 5W charger. Why turbo charge and put permanent strain on your battery when anything that takes 6+ hours will do.

If it's a good quality charger it shouldn't be feeding the battery enough power to impact its lifetime.

A phone will charge as rapidly as it can without undue risk to the battery's longevity. But, it's still a trade-off. If you charged slower, you would decrease risk to longevity.

But when you to bed, your phone doesn't know that rapid charging convenience doesn't matter. So it will still make the same trade-off. If you use a less-powerful charger, you can force it to take its time in charging.

When I got a new laptop this summer I researched what chargers were out there, as I was fed up with carrying the normal assortment of cables and chargers. I settled for another GaN charger - the Innergie Powergear 60c[0] which is a very decent size for 60w and not having a mains lead built into it (still very common on non-mac chargers) makes it a lot more compact. I travel a lot, often with more than one laptop, so…

Their photos all seem to be hiding the connector between the unit and the power tip. Is that standard or proprietary?

I've got the same one, very pricey, but amazing to travel with compared to the giant macbook charger. It's only 60W but charges almost as fast as the 87W one for 15" macbooks. It's also really nice to be able to charge all my travel gadgets with one small charger, reducing the number of cables and chargers I have to carry.

I'm hoping that giant power bricks and those adapters that power via barrel plugs will disappear soon, as I find them to be unwieldy and dirt magnets. Computer monitors are most guilty of having some of the biggest power bricks, and I'd love to see them replaced with regular power cables (the ones that plug into desktop computers), or the monitor be powered over usb-c so any regular 100W usb-c adapter can power them.

Ironically, the best USB-C charger for something like a phone (laptops come with chargers, anyway) I've found is simply the Raspberry Pi 4 USB-C charger - very cheap ($10), small, plenty power (15W), fixed cable and no fucking blue Anker LED that can illuminate your bedroom.

I bought a roll of cheap 5% window tint and put it over all device LEDs. It makes it dim enough to not impact sleep but still visible. If you don't want to see the LED you can cover it with electrical tape.

My preferred alternative to electrical tape is a piece of aluminum foil stuck on with painter's masking tape. Aluminum foil (or any metal) is really excellent at blocking all the light, and painter's tape doesn't leave residue.

I think GaN transistors are a major thing in the next decade. Designed a GaN FET based small vehicle motor controller few years ago and similar size/speed/efficiency is currently not achievable with any other mass produced transistor type. There used to be only small players on the field (GaN Systems and EPC) but now Panasonic and Infineon have started offering their versions. Expecting the prices to go down and volumes go up.

>Schuko/Europlug is a very good system. Perhaps it isn't common, but my experience with the sockets in Belgium was scary to me because there were two outlets embedded in a recess quite close to each other. Close enough I was afraid I'd shock myself trying to get a good grip on my plug and pull it out.

That's odd. Could you describe it better since there is basically no way one would be under risk of getting a shock on a Schuko or Europlug without inserting a needle or something similar into the holes of the outlet.

We're just talking about two copper-lined holes next to each other for each power connection. There were two of those spaced closely together in a recess in the wall. They were close enough I could have touched the metal of one outlet while grabbing onto the power plug inserted into the other outlet. Since my power plug adapter is two copper-plated pins that mated with the holes and had no electrical break like you see on a tip/ring headphone jack I assume the exposed metal is live and the pin is live when inserted.

Perhaps there's a hidden mechanism that enables power after insertion? There was no switch for each outlet. I no longer remember if there was a switch for the pair of them but I don't think so as I was worried about getting shocked. This was in a Belgian hotel I visited a few years ago. Sorry I didn't take a picture.

That is controlled in the phone, not in the charger.

I'm still shocked at how poorly most plugs are designed for fitting in various outlets and power strips.

That depends on where you live, but yes, the design used in the USA (known as the 'type A' connector) was very poorly designed. It gives very little mechanical support. The country I live in happens to use the type F connector, which is very sturdy.

I'm pretty sure they mean fitting as in not unnecessarily blocking adjacent outlets. Not as in mating securely.
