uick Charge 3.0 vs 4.0: A Deep Dive
Quick Charge 3.0 (2016):
Introduced with INOV (Intelligent Negotiation for Optimum Voltage), QC 3.0 supports variable 3.6 V–20 V in 200 mV steps—up to 36 W—yielding up to 38% higher efficiency over QC 2.0. It’s also backwards-compatible with QC 2.0.
Quick Charge 4.0 (2017):
Amplifies speed by 20%, efficiency by 30%, and runs ~5 °C cooler than QC 3.0. Critically, QC 4.0 adds USB Power Delivery (PD) and Programmable Power Supply (PPS) support with 20 mV / 50 mA precision. Certified safety: over-voltage, over-current, thermal, and cable-quality checks.
Quick Charge 5.0 (2020):
Supports over 100 W charging, achieves 0–50% in ~5 minutes, and reduces device heat by ~10 °C vs QC 4.0. Built with 15 layers of protection, dual-battery charging, and full compatibility with QC 4.x, QCPD, and USB‑PD+PPS.
⚖️ 2. Quick Charge 3.0 vs 4.0
Quick Charge 4.0’s addition of USB‑PD compatibility makes it a versatile, high-efficiency solution for modern factories and B2B buyers aiming for high-quality yet universal fast chargers.
⚡ 3. Quick Charge 4.0 vs 5.0
QC 5.0 builds on 4.x's foundation but intensifies power, protection, and compatibility—ideal for OEM brands targeting flagship device ecosystem.
🔚 Final Takeaway
QC 3.0: Mid-range standard—36 W, variable voltage, good efficiency.
QC 4.0: Adds USB‑PD support, faster, cooler, safer—OEM gold standard.
QC 5.0: Ultra-fast (>100 W), full protection, dual-battery ready—flagship level.
Charger OEMs and fast charger suppliers, QC 4.0 is today’s sweet spot, but QC 5.0 is the future-proof premium offering your power bank or charging accessory product line needs.
