## Questions & Answers

**Q: How long will this UPS power my system when the power goes out?**
A: Runtimes of any UPS will vary based on the amount of power required by your connected devices.

**Q: Will the UPS automatically switch off from the battery backup when power is restored?**
A: Yes, when adequate power is restored to the UPS and is within the operating voltage range of the UPS, it will revert to passing utility power to connected electronics.

**Q: My UPS is on, but my power button is blinking and beeping.**
A: The battery needs to be connected first. Please read the user manual for instructions on connecting the battery.

**Q: Can I plug the UPS into an extension cord, or does it have to be plugged into a wall outlet?**
