Yes—USB-C delivers 20W PD, charging an iPhone 16 to 50% in ~30 mins.

2. Can I charge a laptop with this?
No—designed for phones/tablets (max 20W). Use UGREEN’s 65W+ GaN chargers for laptops.

3. Is the USB-A port QC 3.0 compatible?
Yes, supports 18W QC 3.0 for Samsung/Huawei devices.

4. Why is dual-port output limited to 15W+5W?
Power is shared intelligently to prevent overheating while charging two devices.

5. Does it include a charging cable?
No—sold separately. Pair with UGREEN’s 100W USB-C cables for best results.

6. Is it safe for overnight charging?
Yes, ThermalGuard™ auto-adjusts power to avoid overheating.

7. Will it work with EU/UK outlets?
This listing is for the US plug version. Check UGREEN’s store for EU/UK models.

No—dual-port max is 5V/3A (15W total) due to power sharing.

9. How does GaN improve performance?
GaN runs cooler and more efficiently than silicon, enabling smaller size + faster charging.

10. What if my device charges slowly?
Ensure you’re using a supported fast-charging protocol (e.g., PD for iPhones).
