The Wileyfox Swift 2 is QC3.0 enabled, but the only trusted brand adapter I can get is QC2.0. What happens when you charge a QC3 device using a QC2 adapter?

I noticed several other questions on this StackExchange, but none of them seemed to answer this particular scenario.

1 Answer 1


From Qualcomm product manager, responsible for Quick Charge

Of course, QC3 is backwards compatible to QC2 so your existing QC2 adapter will charge a QC3 phone and vice versa

(Emphasis supplied)

Thanks for asking this, I was under the impression that it is one way compatibility

  • Would appreciate your feedback once you use the charger please
