Troubleshooting
If you encounter any issues with your JUOVI Portable Charger, please refer to the following common questions and solutions:
- Q1: Why is 90W fast charging not achieved with some devices?
- A1: 90W output requires a PD-supported device and a 5A cable used on a single port. Power is reduced during multi-port use or if the device doesn't support Power Delivery (PD).
- Q2: Why is the rated capacity not 20000mAh?
- A2: The 20,000mAh refers to the total energy of the internal battery cells. The actual capacity delivered to your devices (rated capacity) is lower due to necessary voltage conversion and is typically around 13,000mAh (at 5V), which is standard for all high-quality power banks.
