The QC3.0 Fast Charging Adapter is not just about speed—it’s about intelligence. The internal IC chip communicates with the connected device to negotiate the optimal voltage and current, reducing heat buildup and protecting battery health. For home office users, this means your phone can go from 0% to 50% in about 30 minutes (depending on device capacity), giving you more time to focus on work. The dual-port design eliminates the need for multiple chargers, reducing cable clutter and freeing up power outlets.

Frequently Asked Questions
-
Q: Does this adapter support non-QC devices?
A: Yes, the Smart USB port automatically detects any device and delivers up to 5V/2.4A. The QC3.0 port also works with standard devices but at 5V output. -
Q: Can I use this with my iPhone 14?
A: Absolutely. While iPhones do not support QC3.0, they will charge at full speed from the Smart port (5V/2.4A) – about 80% faster than a standard 5W charger. -
Q: Is the adapter safe for overnight charging?
A: Yes, it includes multiple protection mechanisms and automatically stops charging when the battery is full, preventing overcharge. -
Q: What plug types are available?
A: We offer US, EU, UK, and AU plug options. Foldable prongs are available for the US version upon request. -
Q: Does it support Qualcomm Quick Charge 2.0 or 4.0?
A: It is backward compatible with QC2.0, but not QC4.0 (which requires different voltage negotiation). It will charge QC2.0 devices at high speed. -
Q: What is the total output when both ports are used?
A: The adapter intelligently allocates power. Typically, the QC3.0 port gets priority, and the Smart port may be limited to 5V/1A when both are active, but total output does not exceed 18W. -
Q: Can I order customized colors or logo?
A: Yes, we offer OEM/ODM services. Minimum order quantity for custom colors is 500 units, and for custom logo printing it is 1000 units. Contact us for details. -
