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. This includes using AI responses and summaries.

Wired is more efficient, you can pick it up and use it while charging, and the cable usually comes free with the phone. What is the point of wireless charging pads?

I know people love these and I'm not going to go and break anyone's balls but the reality is, because it is inductive charging you will never get clean voltage

Anything electronic, it really doesn't matter what it is, is going to suffer basically the equivalent of "mechanical damage" when powered/charged with unstable current

An inductive charging is always going to be highly unstable, there's no way around that

Anybody who tries to tell you different just doesn't understand that this is a real thing, and yeah, really nobody should ever use wireless charging unless they're willing to accept continual device (battery) damage

[–] friend_of_satan@lemmy.world 2 points 3 days ago (5 children)

Can you explain why it's not possible to stabilize the voltage on the receiving side before the power is sent to the battery?

[–] Krudler@lemmy.world 1 points 3 days ago* (last edited 3 days ago) (4 children)

That can be done but the voltage that it receives is variable so that's causing damage. Which ripples down the chain, it's not avoidable no matter how much you put in capacitors and diodes

It's really just an unavoidable aspect of electricity, people think of it as magic fairies floating through wires but really it's like ropes pulling on things, and just like mechanical things, ripples and vibrations fk things up!

If you're really want to get down to it, electricity is destroying things by its very flow. But you want to reduce the unwanted harmonics as much as possible and wireless is not the way to go

You just repeated your claims without explaining them or backing them up with any details. You sound like someone selling essential oils and crystals as medicine. Try again?
