## Questions & Answers

**Q: What power station can the B300K be connected with?**
A: B300K can be connected to BLUETTI power station models: AC200L, AC200MAX, AC300, etc. However, this B300K with CA90 battery extension (short cable) can only be connected to Apex 300.

**Q: What's the recharging ways of B300K?**
A: B300K's charging input power matches that of the connected host power station, allowing it to be charged simultaneously with the host through wall chargers, solar panels, car chargers, or generators.

**Q: Can the B300K battery module be used alone?**
A: Yes. B300K features an 12W USB-A making the battery module works flawlessly when standalone.

**Q: B300K & portable power station charge together, reaching 80% in 45 min. Does this mean both reach 80% at the same time?**
A: "80% charging in 45 minutes" refers to the B300K's maximum charging capacity. If the energy storage device's input power is insufficient, it will not be possible to charge both devices to 80% in 45 minutes.
