The Power Adapter

The 3-pin socket in the adapter begs to be turned 90 degrees. This would help the adapter to stay flat with the wall. This is especially important for the UK plugs.

See https://www.amazon.com/JORINDO(PA0238)UK-3-Prong-Male-Power-Adapter/dp/B093BJWKJG as an example. With the current socket orientation the adapter will hit the wall. If the socket were turned 90 degrees, the adapter would stay really close to the UK wall socket. The same is true for US right angle C3 to wall adapters.

UK plugs are said to be the safest in the world, and if you know the history of the design, it’s clear why that might well be the case.

…it was designed by a woman with children.

BS 1363 all the way.

This is mine currently. I swiped the adaptor off a old Dell tablet my GF had.

Found it…the ‘duck head’ they seem to call this:
(UK)

and (US…flips the right way…but the body isn’t in the correct orientation)

and (Canada…but this doesn’t flip the right way…unlike the two above)

Yup. This orientation. Thank you for the links!

Yup, and I appreciate that. I already had a couple nice 60W USB-C power adapters from my Chromebook Pixel 2015, that work swimmingly with the Framework :slight_smile:
Will certainly consider the Framework one if I need a new one at some point though.

Hello to all,

I like this notebook very much and I am planning to buy or order one.
I have a very old notebook and this I want to renew however I have noticed in the past that many power supplies are NOT grounded. I have an Apple MacBook Pro from 2010 (yes, I still use it as my daily companion and it still works!) and I am lucky that the power supply is grounded WITH the extension cord.

Why I pay attention to the fact that power supplies should be grounded and I have not yet found a good alternative is the following, as soon as a power supply from the notebook is not grounded and the notebook is made of aluminum, then I always feel a “tingling” on the notebook and that is very unpleasant for me.

That is why I have never bought a new notebook since then. But your notebook knocks my socks off that I actually want to strike IMMEDIATELY as soon as my question is clarified, which is very important for me.

If the included power adapter is not grounded, will there be a power adapter that is grounded and does not pass power to the notebook or make me tingle?

Are there similar experiences with something like this? Can I use perhaps SAFE alternatives that are grounded?

To save you the time, yes it is grounded, and you could also buy any USB-C 60w+ charger that is grounded and it should work just fine.

This article (Mac-Tipp: Warum das MacBook beim Laden in den Fingern kribbelt | News | MacTechNews.de) [article is in German] says that only “Schuko” plugs prevent touch current. Is this article then not correct or does the power adapter have other precautions?

This then means that the laptop has also been grounded? I have to ask precisely because I don’t want to order one and then find out that it tingles for me to send it back. Costs time and nerves and certainly harms the environment.

Have you tested the shield of the connector itself as that should be connected?

I can feel a difference. If I connect my ungrounded mobile phone charger to the Framework laptop it is tingling, but with the Framework charger it is not.

Since I would only use the original power supply either way, that would be happy news for me!

Hello,

I have been using a MacBook Pro for years. One can plug the power adapter directly in the wall socket thanks to a 2 prong ungrounded plug, or use a 3 prong (grounded) cord.
I can feel the tingling with the 2 prong. It disappears when grounded.
So I can confirm with my MacBookPro, what @Viandant experienced with the Framework.

I am in the market for a Framework Laptop (12th gen) and a power adapter.
I like the Framework power adapter because it is grounded + efficient + small. And as @mvw , @OneDroid and @Jason_Dagless said, you can use a stubby plug instead of the cord.
But it only has one USB-C charge port.

I could find only one efficient + small power adapter with multiple charge ports that is grounded. But it is sold by un unknown company : Phone Planet.

Did any of you try / use this power adapter (preferably with the Framework laptop) ?
Do you know other brands that sell the same power adapter (so I can find more people that used it) ?
I obviously have less confindence in Phone Planet as in Framework…

Hi @Cobus. I linked above the adapter that I ended up with. Here’s the post:

I’ve been using it quite a bit and it’s the only adapter I travel with now. This is the one:

https://www.amazon.com/Charger-HyperJuice-3-Ports-Foldable-Smartphone/dp/B08PHG2T4P

Unfortunately, it doesn’t look like it’s available anymore. They do have a 100W and a 140W version though.

Hope you can find one that you like.

This power adapter is not grounded.
This is a no go for me.
Thanks @mvw for your link nonetheless !

Aha, my bad. Read your comment too quickly.

I haven’t had any issues with tingling or with running an ungrounded adapter, but I won’t tell anyone not to use a grounded one!

Just to back this up, I’ve absolutely seen this for the MacBook. Both in terms of that sensation, and even with getting electromagnetic interference in a lab setting (someone was resting her hand on the aluminum frame of her MacBook and getting a ton of 60 Hz noise in a signal until we realized what was going on). So yeah, grounding all that metal makes sense to me too.

It’s not super-important but is usually “preferred”.

However, the “uneducated mass” people want more “convenience”, and as power supplies get smaller people start to want to make then two-prong "wall-wart"s. For whatever reason. Great example is Anker, who make very quality chargers, but tie them to 2-prongs.

Unless they are anker-sized (and even then) they are much more prone to being dislodged because they are a lot larger than a two-prong plug (and heavier)
(html tag picture. decent!)


Not unlike this infamous Baseus. Although this is a bit of an extreme, but Lenovo decided to jump on this same bandwagon. More is following suit.

I think the Framework charger is brilliant. I bought one not even owning a Framework (yet)

The only thing I see people wish to get is a “stubby cord” or a direct-plug. But even then, a cord offers more range and flexibility (and less plug damage)

Or maybe a type-C cord that do not have a 90 bend, since depend on the “departing” angle of the cable (related to the laptop) there can be extra stress on the connector. My current use-case see it frequently dislodge from the laptop

I get around the “one-port” limitation by plugging in things that I also want to charge to my laptop (e.g. phone, tablet). Alternatively just get another dedicated phone charger.
