UGREEN US3000 120W Max. 12000mAh (4x3000mAh), 43.2Wh (14.4V 3000mAh) Battery Rated Energy, Lithium-ion Battery, Compatible with DH2300, DH4300 plus, DXP2800, DXP4800, DXP4800 Plus & DXP480T Plus

The UGREEN US3000 is a 120W battery backup with a 12,000mAh lithium-ion battery and 0-second switch to battery power, suited to users who want backup power for compatible UGREEN NAS devices, including the DH2300, DH4300 Plus, DXP2800, DXP4800, DXP4800 Plus, and DXP480T Plus.

Recommended For

• UGREEN NAS owners who want brief power interruptions or outages to trigger a safe shutdown instead of an abrupt loss of power; the US3000 is designed for compatible NAS models and integrates with UGOS shutdown controls.
• Owners of a supported UGREEN NAS—such as the DH2300, DH4300 Plus, DXP2800, DXP4800 Plus, DXP4800 Pro, or DXP480T Plus—who want a compact, dedicated DC backup for that NAS.
• Home NAS users who mainly need time to ride out brief power dips or shut down gracefully, rather than keep storage running through a prolonged blackout; reported runtime is about 8–10 minutes, depending on load.
• Users with a space-limited desktop NAS setup who prefer a small, single-device DC backup over a conventional AC UPS.

Real-World Use Scenarios

• When a brief power dip hits a compatible UGREEN NAS, the US3000 switches to battery power so the NAS can keep running instead of immediately losing power.
• If power fails while the NAS is writing files or running a backup, the US3000 can keep it powered long enough for a configured safe standby or shutdown, reducing the risk of an abrupt interruption.
• For an unattended home NAS, such as one storing shared files or backups, a power outage can trigger an automatic standby or shutdown when the UPS is connected and configured, rather than leaving the NAS to run until its battery is depleted.
• During a longer outage, the US3000 is best treated as a bridge to safe shutdown—not as a way to keep NAS services running indefinitely; active transfers or workloads use battery power while it lasts.
• If you want to check the UPS after an outage or while away from home, the UGREEN app can show its status and battery health; the NAS and UPS must be set up for those monitoring features.
