Hello.
Laptop AC adapters use a special DC cable - it is coaxial and rated for currents up to 10A for certain laptops, while being relatively thin and flexible.
I need such DC cable, but can't find it on digikey, ebay or whatsoever - for sure, there are sold replacement DC cables for all kind of laptops, but, with a fixed length, while I'm looking for a longer piece of such cables, say, I'd buy a whole 100ft roll, , and without any DC plugs on the ends (I'll add my own)
Any ideas?
