No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

I always see laptops come with larger bricks that have separate mains cable which plugs into the brick. Even if the adapter has some low power rating.

Example for comparison:

On the right is a standard laptop adapter.
Same price, same connector, same protocol, same power rating, far different size.

Why is that so?

Actually, the GaN adapter on the left also advertises itself as being meant for laptops, but by default, almost all laptops will come with something like the one on the right.

Or is it simply cheaper to manufacture while being sold for the same price?

Or is it simply cheaper to manufacture while being sold for the same price?

Yes, it's mainly that. Most vendors don't make their own power adaptors anyway, since there are strict requirements for power adaptors that are plugged into AC wall sockets in each country. The stuff inside the large brick is likely sourced from somewhere else, who has all those certifications worldwide. Note that it also uses standard AC power cable plugs. That large brick can be shipped worldwide by simply changing the AC cable it ships with.

The small GaN Brick is also outsourced, but since it is smaller it is probably more expensive to build. However, the AC plug is integrated into it, which means the seller has to stock physically separate units for each plug type if they want to ship worldwide.

As far as the price is concerned, this one shop is selling them all at around the same price, but I bet the MSRP on the Lenovo one is much higher, because of the brand. The parts inside the Lenovo one are probably cheaper.

Heat soak. A laptop may be expected to run 24/7. The larger bricks can dissipate the heat. A GaN charger can do it as well, but most of them have a heat soak point where they stop delivering full power
