Is it advisable to use non Apple cable

As rom.ph said, it is alright to use 3rd party charging cables as long as they are "Made for iPhone" (MFI) certified.

You can find some documentation on that here:

Identify counterfeit or uncertified Lightning connector accessories - Apple Support

Hope this helps!

There are two types of non-Apple cables - one that are Made for iPhone (MFI) certified and the others that aren't. You are safe with the MFI-certified devices, but the others are risky, specially when they are from unfamiliar brand names.

depend on where you live, where I live non CE certified cables would not be legal to sell,

but at the end of the day a cable is some pins on a connector connected to some thin copper wires to the connector in the other end
