Frequently Asked Questions
Does Quick Charge work with iPhone?
No — iPhone uses USB Power Delivery (PD), not Quick Charge. For iPhone fast charging, you need a USB PD charger like the Apple 20W or 40W.
Is QC 3.0 faster than USB PD?
For phones that support QC 3.0, it's comparable to USB PD at similar wattages. USB PD is more universal and supports higher wattages (up to 240W), making it better for laptops and tablets.
