Changing existing modem to one with usb-connection, can I connect as photo and is it easy to distinguish live feed in usb cable?, cheers IMG_0390.jpeg
 
Wait for others to answer this, whenever I have tried to do anything with USB cables the combination of fine wires, poor eyes and shaky hands has led to failure more often than not. USB-C carries more power so wire (strands) may be better to work with, I don't know
 
I cannot make out exactly what you are doing. But remember USBs work on only 5.5v not 12v. If your equipment runs on 5.5v you will require a transformer. The brown cable should be positive. If you wire equipment wrong way round you could damage it, but more likely it just won’t work. If you have a multi meter you can check polarity on it. If the reading has a - in front of it, it’s the wrong way round.
 
I’m planning to swap from Teltonika to netgear nighthawk which seems to work right out the box but want it on 24/7 so need constant feed
 
Hmm, I'm not sure what you're trying to achieve tbh.
What are we looking at in the photo and which bits are significant?
What is the USBC to be used for, input power only or is it carrying data too?
How was the original modem.powered? What voltage? How was it connected? Was it powered 24/7?
Which connector type was used?

My Netgear used to work for hours on single charge, even when constantly being used. Also without an external aerial its positioning within the van could affect its performance. So unless you are intending to connect it to an external aerial its would consider not having it permanently connected, thus allowing you to position it as required.

If only it were that simple. USB runs on loads of different voltages, all the way up to (and beyond) 20v. Especially USBC

I saw no mention of USB C.
Standard usb run on 5-5.5 v.
USB C can run up to 20v

A standard USB port provides a voltage of 5V. The maximum current and therefore power output can vary depending on the USB standard and port type. USB 2.0 ports typically provide 0.5A (2.5W). Newer standards like USB 3.0 and USB-C can deliver higher currents, up to 0.9A (4.5W) or even more with Power Delivery

Here's a breakdown:
  • USB 1.x and 2.0: 5V with a maximum of 0.5A (2.5W).

  • USB 3.0: 5V with a maximum of 0.9A (4.5W) for standard ports, and up to 1.5A (7.5W) for charging ports.

  • USB-C: Can support higher voltages and currents with Power Delivery, potentially up to 20V and 5A (100W) or more.

You can't have looked hard: I mentioned it in the post you replied to, as well as it being the subject of the thread.

Sorry, but that is just plain wrong. It may have been true once, but not for several years.

I tried to run my nighthawk M6 from a usb-c socket with a usb-c to usb-c cable, it said that I was not using the correct power socket and wouldn't run, thanks, I will try this

This one will insist you leave the battery in. Which I'm OK with as it ran really hot without the battery and connected with their power supply.

If you are using the ethernet port that needs to be re-enabled in the settings. Ask me how I found out about that 🙄🙄🙄🙄🙄
