What do I need to buy to get TB3 charge power? Ran out of Thunderbolt USBC connectors
My laptop has two USB-C Thunderbolt connectors. One is for the eGPU (an XG Station Pro chassi), and the other one is for the Thunderbolt 3 network adapter (e.g. Promise Sanlink).
Neither of these provide laptop charging.
This means that in order for my laptop to charge, I need to get some way to impart the power from my Lenovo USBC charger cable, into the Thunderbolt cable.
What special adaptor/cable can I use for this purpose?
Possibly the only way to solve this would be that I buy a Thunderbolt 3 PCIe chassi that does have daisy chain, and put a networking card in it, this way I would have one Thunderbolt connector over.
Also possibly that chassi would have a charging function, in this case i could put eGPU still on one Thunderbolt and the NIC on one Thunderbolt, and charging would be solved also.
That would require me to buy one more chassi and one more NIC though.
Maybe I need to buy a special power supply, which forwards the Thunderbolt 3 pins to an USB C Thunderbolt 3 connector, altogether.
Let me know what you think is the slimmest best option, thanks!
Simple solution is to replace the XG Station Pro with an enclosure that does provide at least one power delivery (PD) TB3 port of 60W or greater:
The greatest flexibility may come from the AKiTiO Node Pro. It uniquely providing 60W PD from each of it's two TB3 ports.
@cmm Just an idea but have you tried daisy-chained the Promise Sanlink to the USB-C port on the ASUS XG Station Pro? That expansion port is confirm to be USB 3.1 gen 2 and may not cripple 10Gb/s Ethernet connection. It does impinge on eGPU bandwidth however.
The ASUS XG Station Pro USB C port is not Thunderbolt while the Sanlink was always Thunderbolt. Especially because up until 2016 or so the fastest Fibre Channel was 16FC which definitely needs the 20 gbit/s of TB2, as the name suggests, it's 16gbit. And honestly, even 10GFC (available since 2008) barely or not at all fits the 10gbit of USB C.
As for 10 gig ethernet over USB C, the market for such would be so incredibly tiny -- it is only for customers who wanted a ten gig network port but doesn't have Thunderbolt on their laptops? Yeah it would be cheaper, for sure, but given how much a 10gbe network still costs...
