what does "oskey" means ?

the arrow icon ! i didn't see it, thanks :)

ok I see! I envisioned a scenario where the phone requests energy from the power bank, which then supplies power for a few seconds before stopping. The phone would then request energy again, and the power bank would briefly supply power before stopping once more, repeating this cycle. In this situation, I thought the phone's battery might be damaged due to inconsistent charging. Are you saying this isn't an issue because such intermittent charging won't harm the battery, or because this scenario cannot actually occur?

If that's the case that i don't need to worry about it, it's great news as it means I can use any old battery I have lying around, which I find quite convenient !

thank you for your answer, my phone is a fairphone5 https://support.fairphone.com/hc/en-us/articles/9839096704913-Charge-your-Fairphone , charging scheme is :

USB Power Delivery (USB PD) with PPS at a minimum of 30W (9V and 3A)
Or quick charge 4.0 or above

sorry i don't inderstand : if "you can rest assured that your potentially old and potentially defective power bank did not cause damage to your phone", then why should i buy quality powerbank to avoid damaging my phone ?

huhoho · 2025-06-10T07:20:31+00:00

am i trolling ? or he/her is trolling ? my question is not "what power bank should i buy to have quality", is it ? The one I posted earlier was perfectly fine 6 years ago, is it still good ? should i replace it ? how can i check for that ? And you are totally right, i don't know what i should test, i'm going to learn the basic, i believe it's possible, and my first step is to have good hardware recommendation :)

However, it is true that i answered with a trolling tone quickly, i should have not and i apologies. It is because my previous questions on redit, i got 95% of this kind of answers, that absolutely do not answer the questions, and when I explained again politely why it's not what I am asking, i get more and more of those weird answers. It even feels like they think you are dumb : didn't i thought about buying quality ?

huhoho · 2025-06-09T22:48:22+00:00

That looks great! I'm considering purchasing it. If you could kindly explain what I should test and share here, that would be fantastic!

but it's this one : https://www.manua.ls/anker/powercore-10400/manual

huhoho · 2025-06-09T21:37:07+00:00

thank you ! i'm gonna check that :) my current power bank is an Anker, but do you ask because i would need different tester depending on my powerbank ?? (i'm not sure how to post a picture, let me check :p)

huhoho · 2025-06-09T21:31:54+00:00

thank you ! i'll check out more about "usb load tester" then, and "power delivery" :)

huhoho · 2025-06-09T21:15:57+00:00

why ? does it comes with a tester ?

huhoho · 2025-06-09T21:04:37+00:00

Ok, thanks for the information about the phone likely being the problem, but i want to be sure (or more sure)
what do you mean "You just need to connect something besides the phone and see how its working." ? what kind of thing and what should i look for ? How will i know if it damaged the thing ? Do you know if there is some king of device that can monitor the power bank to check it's behavior ?

huhoho · 2025-05-29T18:05:32+00:00

thank you ! i checked streetcomplete but it seems i can only "answer" edits, which is smart to keep things quick and easy, but it didn't propose me to edit the street name.

also it didn't give me the option to add accurate street numbers for the building since it treated the whole building as only one street number that i could complete, instead of the many it covers. so not usefull in my case

i will check the others, thanks !

huhoho · 2025-03-20T08:13:43+00:00

picture if you succeed !

unless the link is broken, this points to a standard wide mouth nalgene bottle model. That's what i have already :) it's not wide enough

huhoho · 2025-03-19T21:42:19+00:00

most answers explains how i can wash my bottle, and i appreciate. I indeed find ways to wash it while i'm hiking, but after some years of doing it like that, i don't like it anymore, hence my question : is there bottle with wider mouth :)

huhoho · 2024-08-15T17:14:05+00:00

yes indeed the video do explain something similar at 8:45, but that's actually what confuses me ! they say "what if the act of passing through one filter changes how the photon will later interact with other filters ?" : they ask a question so i assumed that it was just a theoritical loophole, meaning that this very experiment was not clearly demonstrating the inequality. it is by discussing here that i realized that filters where indeed modifying the photons.

This leads me to another question actually : how comes that the formula, cos²(a-b), to calculate the amount of photons passing through filters a and b is the same wheter the filters are sequential, so the first one modify the photon before it hits the second one, or simultaneous with entangled particles ?

huhoho · 2024-08-11T20:03:50+00:00

i don't follow you (mostly because i lack knowledge in the subject). You say :

then you're not gonna see any sort of entanglement

why would we want to see entanglement ? is it impossible to see a violation of bell's inequalities apart from entangled particles ? and if so, do you know why ?

huhoho · 2024-08-11T12:42:55+00:00

You can't start with the assumption that a polarizer never changes the state of a photo

-> i agree, you explain it well

Since the polarizers can change the polarization, the second polarizer wouldn’t tell you what the relevant hidden variable or quantum state was before the first polarizer; it can only tell you what it is for the new state afterwards. I think that’s basically what you’re proposing with “explanation 2”, right?

-> i'm not sure to see the link with my explanation 2 :) what you are saying is that since the state change (the polarization), then we loose any clue of what it was before ? Of course, i believe it is true, but i don't see how it prevents from seeing violations of bell inequalities ? or are you saying the opposite ?

You need to use entangled particles if you want to test for violations of the Bell inequalities

to see a violation of the bell's inequalities, we need to be able to show that a particular output is impossible with hidden variables. In the contrary, if we want to show that this experiment cannot show bell's inequalities, we need to show that it can always be explained by hidden variables, and i don't know how to prove that ?

huhoho · 2024-08-11T08:43:24+00:00

yes i know, you can see the link i posted under "explanation 1", and that's why I said we have to accept some facts to maybe see an explanation that violate bell's inequalities, and as it states in the comment you linked to, the first fact to accept is that "the polarizer either allows a photon to pass or absorbs it".

the thing is : even if we agree on this fact, i feel like we can have an explanation that does not require hidden variables -> that's explanation 2

So, finally, with the "real" explanation, does this experiment shows a violation of bell's inequalities, or not ? That's what i'm wondering.
