The 75 watt, 4 outlet charger I bought was a Chinc product (aren't they all, nowadays?), branded Satechi. I cannot say more about it than it works for me, but I have never been within the claimed 75 Watt output power. In particular, I do not know if it would work satisfactorly if you draw that maximum from a single one of the four ports. I wouldn't be surprised if the max power should rather be distributed over all four outlets!
So far, products from China ("which we call Red China") cannot unconditionally be trusted for through quality. In the 1960s and 1970s we were thinking of Japanese crap in similar terms. Behind that blurred curtain of mistrust, Japan built a truly high quality camera industry, an electronics industry and a car industry that knocked the feet away under hundreds of Western manufacturers.
Chinese manufacturers are no longer a joke. Some of the procucts they make are certainly up to standards.

Hi I couldn't get a Satechi but got something similar - as for Chinese quality the boards are made in China anyway

could you use a 24v psu, and hook 4 adjustable power bucks up to it, and power the SBCs from that?
I don't think a powered USB hub would provide enough power (1-2 amps at the most, and a raspberry pi (for instance) needs three amps for power.

Hi John, not familiar with power bucks I'll check them out

Getting a bit out of my depth here methinks - how would i connect 4 of them to a power supply and then out to my boards ?

run wires from the psu to the power bucks, and then run cables from the bucks to the Pis. Your other option is a UPS and plug all the pis's into it. That's much more expensive, but you get the highly valuable added protection of the UPS. I have an 1100ma UPS dedicated to a bank of six Pi's.

The UPS sounds good John my boards aren't Pi's but they have very similar power requirements - running cables from the bucks would be tricky as all the boards are in cases. What do you use your Pi's for ? I've used one for years coupled with a £35 DAC hat from hifiberry to stream my digital files to my analog amplifier - it has no right to sound as good as it does. I also have a £1500+ DAC and while it's better quality - it certainly isn't £1465 different. Can you send a link for the UPS ?

A database server for my three home theater boxes (also Pi's), three DNS servers (using PiHole), and a controller for my 3D printer. One pi is simply a spare in case one of the other ones fail.
I have a crapload of Pi's (all are Pi4). They're smaller and more economical than a full-blown PC, and can be fully outfitted for less than $100 (each)

I love playing with these little boards I use these NanoPi and use them for hosting personal Docker NetCore API projects which utilise a postgres database , NGinx as a reverse proxy etc...

Do you have your Pi's in a cluster ?

No, but if I werent so old, I’d explore that.

Let's face it - there's a high percentage of software developers who have great technical skill but whose people skills leave something to be desired.
I'm one of them. I've encountered a lot of others too.
I don't think it's a bad thing.
Especially where it concerns matters of what is possible, and what isn't, and what will work, and what won't the question comes down to "Do you want honest, or nice?" The rest is just in how you deliver it.
So delivery aside, given the situation where it's one or the other:
Many developers would place a premium on honesty.
Many folks with "soft skills" would place a premium on nice.
The people that need the honesty the most - because of their tendency to be unrealistic when it comes to technical matters - is the folks with the soft skills.
The only way out of this double-bind is diplomacy - the art of telling someone to go to hell in such a way that they look forward to the trip. This is not easy. Sometimes it's not even possible - like - "your {family member} died" and developers often don't have the social skillset to do that consistently.
And sometimes even when I hear developers talk to each other they take things personally. A lot of times probably part of it is due to the emotional investment in the project they are discussing - but other times it's just people expecting "nice" and getting "honest" - other developers do it too.
So I guess we can come off as a bit salty. But you know what? You're going to get the truth.
I think we can all benefit in general from remembering not to take things personally.
And some of us can benefit from practicing a little tact.
None of this is intended as judgment. Just honest observation..

not just developers, but people in general.
Honesty is not always polite.

I wish I could agree with you on that score. My faith in humanity isn't what yours is, I guess. I admire your optimism where people are concerned, even if I can't share it.

Just something that was said on the forums a little while ago that made me think of it.
I didn't write it to call anyone out so that's as much as I'll say about that. The thoughts weren't directed at anyone in particular.

Life.
It is a constant struggle to deal with people who use emotion to make decisions, and will happily "throw you under a bus" just to get what they want. The desire for praise over doing the right thing. People who actually have the capacity to hate, then will act on that to make themselves feel better for 2 minutes.
People suck.

When dealing with peers or subordinates, tact is important when giving criticism. Focus on the specific thing(s) that need to be improved, offer helpful suggestions, and don't make it personal.
In my experience, those who needed honesty the most were senior management and executives. Too many people were reluctant to tell them sad truths or engage them in debate. They were also susceptible to being bamboozled by technical people who promised things that couldn't be delivered or touted designs as if they'd already been coded and proven, when in reality they'd been prototyped at best, and it was debatable whether they could ever be productized.

Tell that to the person on the other end. People have a skill of turning anything into a personal attack.

Unfortunately, if you step up to be that person, you just become "the problem employee who is difficult to work with".

All you can do is your best. But there's no cure for snowflakes.
I never had a problem being candid with senior management types. But then again, I never had to deal with them until I was indispensable.

Yeah... I think that goes in my favour more than I care to admit (to myself).

But then again, a memorable quote is, "The graveyards are filled with people who were indispensable."

Quote: "The graveyards are filled with people who were indispensable knew they legally had the right of way."

It's possible to be honest and nice. Up to a point. When honesty demands that the message is "you people are a bunch of incompetent morons", well, nice becomes something that falls more into the "will I lose my job if I'm honest" category than actually being nice.
honey the codewitch wrote: But you know what? You're going to get the truth.
Rarely do people actually want to hear the truth.

And you were so nice about it!
