What max current will the rear USB actually supply 5V at?

I've never used gigabit Ethernet.

All the ethernet at my house is gigabit, except on links to things like HDR Fox T2 that support 100mbit max. I have 300mbit down / 50 mbit up broadband so I do get throughput greater than 100mbit on some operations, typically firmware updates of various things.

All the cabling in the walls and under the floor at my parents house is CAT 6 and within the length limit to be good for up to 10 gigabit, though they only have 100mbit on their router.

Question: Is there some kind of auto-detection which falls back to 10/100 (ie two pairs) if 1000 (four pairs) isn't working?
Click to expand...
Absolutely, always has been. There is also now auto detection of which way round the pairs are so there is no longer any need for cross over cables, I remember needing those unless the hub or switch had a port labelled "uplink" sometimes with a switched for whether it was in crossover mode.

I was aware of that, otherwise my config diagrams above would have been far more complex! Even the HDR-FOX auto-detects, so it's not new technology.

So (jokes about milli-bits notwithstanding), running their AV over "economiser" shouldn't be an issue, if you can smuggle a switch into their setup at the router.

I forget when auto detect of cross over came in. It didn't exist 25 years ago last time I did some cabling in a commercial building.

Capitalisation is all over the place these days anyway. I lost the will to try to get it right when things like 7G started being used heavily instead of 7g to mean 7 gravities of acceleration. 7G is 7 times the universal gravitational constant, except apparently not anymore as I was told repeatedly somewhere so long ago I've forgotten where.
 
As a switch or an accurate Watt-consumer? ;)
He'll have to buy a power meter now to check. Will will probably cost a couple of years' worth of 'leccy...

It says it needs a power supply, and is USB-C. Er, I hope you aren't disappointed.

I have a couple of USB C power measuring dongles already.

It comes with a USB A to USB C power lead, which is exactly what I need. I might prefer a shorter one but those can be purchased.

(Nice find, by the way)

I can't take credit, it was a colleague at work who found it. I was discussing TVs with him which he's quite knowledgeable about and my need for an ethernet switch, and the next day he said "it's all your fault, I spent hours looking and couldn't stop until I found this" which is the switch above.
 
This eSynic Gigabit Ethernet Splitter, can I clarify, the three devices that would then be running off one router port, do they still have their own local ip address? It’s just their theoretical top speed would be the hosts port speed divided 3?

As far as I can tell since I don't have it yet (it's in the Amazon locker awaiting collection), this is a 4 port gigabit ethernet switch and will behave the same as any other switch. It is incorrect for them to describe it as a splitter.

More than likely you mean "running off one switch port", since the part of the device you are calling a "router" is actually the part that contains a switch (AKA the LAN ports).

Of course they do. Why (and how) would they not?

No, the top speed is still 1000 Mbps. You just have to share that in some capacity depending on where the traffic is going.
If it's to destinations via the "uplink" port (the one curiously labelled "input" on the device we are talking about), then all 3 devices share that 1000 - you can't have 3x 1000 going up/down it, but you can have 1x 1000 and 2x 0 or any other combination totalling 1000.
If it's to the other destinations on the device itself, then you ought (unless it's built with a really naff hardware switch chip) to get 1000 between any combination e.g. "output 1" to "output 2" gets 1000 and "output 3" to "input" gets 1000.

I've ordered one of these 4 port gigabit switches since it claims 210mA consumption from 5V: https://www.amazon.nl/dp/B0DPK288PG.
Click to expand...
I have it and as expected it is a straight forward 4 port gigabit ethernet switch. 210mA is a lie, power varies depending on what you have connected. With all 4 ports connected at gigabit consumption is 450mA, which is low enough for my purposes as it is less than 500mA. Thrashing my Apple TV 4K 2022 speed test reads 302 down and 48 up which is what it always shows, and the power consumption of the switch remained at 450mA. I will be buying a few more of these, can't really go wrong at £14.99.

Oh and to prove a point, neither the Apple TV 4K nor the connection to the router are on the socket misleadingly labelled "Uplink". I have my existing gigabit switch connected to that, in a "Downlink" sense in that this device is less hops from the router.
