## Questions & Answers

**Q: What conditions are needed for fast charging a phone with the power bank?**
A: For fast charging via a power bank, ensure your phone, data cable, and power bank all support and are compatible with fast charging protocols, and connect to a fast charging port; note that charging multiple devices may disable fast charging.

**Q: What is low-current mode for the power bank and how do I enter it?**
A: Low-current mode is used for charging low-power devices like earphones; press the button twice to enter (indicators will flash) and press once to exit.

**Q: How can I keep my power bank in the best possible condition?**
A: Charge your power bank regularly. Even if you don't use the power bank for a long time, remember to charge it every six months to keep the battery level around 50%. This is because power banks can discharge even when not in use.
