Are there special cable requirements for Quick Charge 3.0 / 4.0?

I want to buy a battery bank that has QC input and output. I'm wondering if I also need to invest in special cables to take full advantage of the quicker charging rates?

I ask because I've done tests with normal micro USB cables using a standard 2A USB charger and there's a huge amount of variability. Some cables only do 300mA. Some do 500mA. Some do 1.25A.

So I don't want to get a QC battery bank and realise none of my cables work.

Q6: Does it matter what type of charging cable is used with a Quick Charge adapter?
A: Quick Charge is designed to be connector- and current-independent. Quick Charge is designed to be compatible with a variety of formats, including:

  • USB Type-A
  • USB micro
  • USB Type-C
  • Proprietary connectors
Quick Charge high-voltage operation is designed to minimize charging issues associated with long or thin cables, allowing for a superior charging experience, independent of cable type or cable current capability.

That said, when I bought some extra cables for our Galaxy S9 phones, I just bought some Anker cables on Amazon because of previous experiences with their cables, and the description stated they fully supported the S9's charging requirements, and two 6 foot cables were only $12.
