Hello everybody
I need an advice. Is there a high quality USB PSU with multiple ports available which supports multiple RPi’s for 24/7 usage?
It should not get too hot and be stable enough to leave unattended (fire hazard), additionally every port should be able to sustain the power draw of up to 3 Amps.
The market is flooded with thousands of multiport chargers, but I really don’t know which of these are reliable enough.
Thanks for your help!

It depends which Raspberry Pi. I haven’t found anything for an array of 3b+ or even 4b yet, the draw is too high and most USB supplies don’t push out the full amperage to all ports all the time.
My older zeros and 3b (not +) are fine on Anker USB supplies.
From memory Tronsmart Titan is what you looking for but I think they stopped to making it.
You can look here for one which suits you:

the Titan has 90W
Depending on what you are doing with the R-Pis (All in the same case ? Frequent swap ? ... ?) it might be easier to use a 5V PSU wired to the 5V pins of the expansion connector
Thanks! Maybe it is best to wire them directly for now, but there is definitely enough demand for a product like this. Maybe some manufacturer will eventually produce something that meets the criteria.
The array consists only of 3B+ and 4 models and they need to power some USB-Devices, so the power draw is in the upper range.
The StarTech ST7300U3M has 36W for 7 ports - so 5,1W for each port.
