Where can I get a longer version of the USB cable that came with my Nikon D800?.
And what's it called.
I'm looking for about 3 meters long if possible.
You just can't use the clip that came with the factory cable on an aftermarket one, or I can't use it on any of my cables
The maximum recommended length for USB3 i 3 metres but the spec and cable is far more sensitive due to its higher power needs and speeds.
Make sure you get a good cable, do not get an expander.
