Quick Charger Manufacturer FAQ

QC3.0 is Qualcomm’s fast-charging protocol using INOV (Intelligent Negotiation for Optimum Voltage) to dynamically select charging voltage in 200mV increments between 3.6V and 12V. It charges compatible devices up to 4× faster than standard 5V USB.

Most Android smartphones with Qualcomm Snapdragon processors: Samsung Galaxy (S6+), Motorola, LG, Xiaomi, OnePlus, and hundreds more. QC3.0 is backwards compatible with QC2.0. iPhones do NOT support QC — they use USB PD.

The charger automatically falls back to 5V/2.4A via BC 1.2 auto-detection. Every USB device charges safely — no compatibility risk.

Yes — the SQ1040 (single-port 18W), SQ1045 (QC3.0 + USB-A 2-port), and SQ1050 (QC3.0 + 5× USB-A 6-port desktop station). For QC3.0 car chargers, see our Car Charger category.

UL 62368-1, FCC Part 15 Class B, CE, RoHS, REACH. Multi-region plug variants (US/UK/EU/AU) each carry region-specific safety marks.

MOQ 1,000 stock, 3,000 custom. Lead time 25–35 days. Samples 3–5 days.

QC3.0 is Qualcomm-proprietary, primarily for Android devices, max 18W. USB PD is an open standard, supports higher wattages (up to 240W), and is used by Apple and many laptop manufacturers. For USB PD chargers, see our PD Charger category.
