content: Actually, some interesting stuff as project:Just changed workplaces, and at my new job, we have some big transport cases for notebooks with approx 30 of them in it (Flighcases like musicians haul around).For charging, some people before my time decided to put the 65W USB-C power supplies that came with the notebooks in the bottom of that case, wire them together and put some CEE 3-phase plug on it.Works so far, and 3phase CEE outlets are quite common in germany in industrial settings etc.Boss came on and was like "Hey, in some foreseeable scenario we will NOT be able to use CEE outlets in some places, so we will have to be able to charge the notebooks with standard single-phase outlets.In germany, thats nominally 16A 230V, but normally only 10A continuous draw when yu use that for longer time.I thought of getting rid of the 30 individual power supplies that have to be mounted in the bottom of the case, and replace them by getting some 19"/industrial grade Chargers mit USB-C outlets. so 3 or 6 of the with maybe 6/12 outlets each should be able to power the whole 30 Notebooks, meaning roughly 2000 Watts power consumption. This theoretically can be handled by a single Schuko outlet (16A/1phase/230V), so this should work.Problem: I can not find a really industrial grade USB-C charger, that can provide 20V/3A (ok, maybe we can settle for 2A...) on at least 4 ports, and has a power input you can put a standard C13 plug/Cable in it.Exceptions may be:https://www.exsys.de/16-port-usb-c-high-power-ladestation-1008w/EX-11017(Now available again, it seems)or:https://www.siig.com/products/it-products/ipad-tablet-accessories/battery-chargers/16-port-industrial-usb-c-pd-charging-station-1000w.htmlProblem: I have not found a retailer/importer for Siig in germany.Any hints or tips appreciated!

content: I’ve run into the same problem when trying to source higher-power USB-C PD gear for industrial use. Most consumer multiport chargers top out at 100–120W total and just aren’t designed for sustained 2kW loads. Haven’t yet found a true “industrial” USB-C brick with multiple 20V/3A outputs either.

content: I'm not understanding whats preventing you from just changing the 3 phase CEE plug to a 16A 230V type f or C320-C16, C19 socket?

content: Quote from: thm_w on September 24, 2025, 10:19:09 pmUsually inrush of many many power adaptors (or leakage current) will reach a point where it trips upstream breakers. But it sounds like the OP while heading in the way you suggest was looking to improve the “manufacturability” at the same time.
