It's not just the quality of the wiring but the way the circuit board is laid out and the type of components and design that is used.
Lots of cheap knockoff chargers cut corners with the design that at best merely compromises the quality of the power delivered to your device and at worst is an electrocution or fire hazard brought on by dangerous design choices. Not isolating the HT side from the LT side adequately is one example.
I would not take a chance with a knockoff charger.
Edit: I should add that reputable manufacturers like Belkin or others that make third party chargers are different. I'm talking about knockoff stuff that claims to be legit, or makes no bones about being ultra cheap.
