PD vs QC on Power Banks: Will It Fast-Charge Your Phone?

A power bank only fast-charges your phone if the two agree on a protocol — a handshake that lets the phone pull more than the safe default of 5V/2A. The two that matter are USB Power Delivery (PD) and Quick Charge (QC).

USB Power Delivery (PD)

The open standard, carried over USB-C. It scales from phones to laptops, and it's what iPhones and most modern Android phones use.

• Look for "PD" and a wattage: PD 20W, PD 30W, PD 45W.
• A PD power bank with a USB-C port will fast-charge an iPhone, a Pixel, a Samsung (via PPS, a PD extension), and can top up many laptops at 30W+.
• PPS is PD with fine-grained voltage steps — Samsung's "Super Fast Charging" needs it specifically.

Quick Charge (QC)

Qualcomm's protocol, usually on USB-A ports. QC 3.0 is common; QC 4/4+ is PD-compatible.

• Look for "QC3.0" on the USB-A port.
• Fast-charges older Xiaomi, Realme, and other Snapdragon phones that predate widespread USB-C PD.
• A QC-only bank will not fast-charge an iPhone — that needs PD.

Will it fast-charge my phone?

Check your phone's box or settings for its charging spec, then match it.

The cable matters too

PD above ~30W needs a USB-C to USB-C cable rated for the current — a 3A cable caps you around 60W, and a no-name cable can cap you far lower. See Which Cable for 65W / 100W Fast Charging.

Bottom line

• iPhone or a recent Android → buy a PD power bank with USB-C, 20W minimum.
• Older Snapdragon phone → QC 3.0 on USB-A is fine.
• Want both, or future-proofing → a bank with PD on USB-C and QC on USB-A — see our power banks range.
