The cable is ok quality. Does it's job.
Sometimes there are not enough sockets in powersource, so have to share power.
However you should also consider some side effects.
Some pedals bleed effect a litlle thru power cable.. For exampe you could hear a tiny pit of flanger going on even tho that pedal is not on, but power-cable-connceted analog delay pedal is on. That is one reason people like to use isolated powersource outputs or batteries.
Then pedals require different amount of power. If you have chained pedals requiring lots of power and your powersource output can't put it up, your pedals might light up like its on, but there is no sound.
