The UGREEN NAS Backup Power 120W (model US3000) is a dedicated UPS for UGREEN NAS systems, designed to protect data and prevent unexpected outages. In the event of a power outage, it automatically takes over the power supply without interruption, as it offers a 0-second switchover time. This ensures the NAS remains active long enough for a safe shutdown and data protection.

The device uses a lithium-ion battery with a capacity of 12,000 mAh and an energy capacity of 43.2 Wh. The built-in smart processor enables communication with the NAS system via a USB connection and supports automatic power on and off when the power status changes. The UPS provides a maximum output power of 120 W and includes multi-stage protection against overvoltage, short circuits, overloads, and other electrical irregularities.
