Who it fits
Good fit for
This UPS suits owners of 2-bay and 4-bay UGREEN NAS models, including the DXP2800, DXP4800, DXP4800 Pro, DXP4800Plus, DXP4800Plus, DXP480T, DH4300Plus, and DH2300. You should choose this if you need automatic shutdown capabilities via app notifications or orderly task pausing during blackouts. It is ideal for home or office environments where unexpected power loss could corrupt data. The quiet operation and compact gray design make it a practical addition to your existing storage infrastructure without adding noise or bulk.
Who should skip it
You should look at another option if your device is not on the compatible list. The product explicitly states it is not compatible with the DXP6800 Series or DXP8800 Series. You must double-check your model name before ordering. If you require AC output for other electronics, this unit only provides DC power. It is also not suitable for users who do not use the UGREEN ecosystem or need runtime significantly longer than ten minutes. Verify your NAS model to ensure this backup power solution will actually work for your setup.
Verdict: The UGREEN US3000 is a spec-focused backup solution for specific UGREEN NAS models, offering 120W output and ten minutes of runtime. It protects data through automatic app-controlled shutdowns and zero-second power transfer.
UGREEN US3000 Key Specs Explained
Output Wattage: 120W
This rating tells you the maximum power the unit can supply to your NAS. You need to ensure your specific drive configuration draws less than 120W. If your setup exceeds this limit, the UPS will overload and shut down, leaving your data unprotected. Always check your NAS power consumption against this ceiling to ensure safe, uninterrupted operation during grid failures.
Battery Capacity: 12000mAh
This figure represents the energy storage volume inside the device. It determines how long your NAS stays online after the power cuts out. The listing notes this provides about ten minutes of runtime. This window is usually enough to save open files and trigger a safe shutdown sequence, preventing file corruption on your internal hard drives during sudden outages.
Battery Chemistry: Li-ion
Lithium-ion cells are standard for modern compact UPS units. They offer high energy density in a small form factor and generally hold their charge longer than older battery types. You benefit from a lighter, more compact unit that fits neatly beside your NAS. This chemistry also supports efficient charging cycles, maintaining reliability over the device's lifespan.
Dimensions: 8.07 x 5.31 x 1.46 inches
These measurements show the physical footprint of the unit. The low profile allows it to sit directly under or beside compatible UGREEN NAS models without taking up much desk space. You can verify these numbers against your available shelf or rack space. The compact design ensures it integrates cleanly into your home office or server setup without clutter.
Design and Build Quality
The UGREEN US3000 is a compact unit designed to sit alongside your network-attached storage. According to the listing, it measures 8.07 inches in length, 5.31 inches in width, and 1.46 inches in height. This small footprint allows it to fit neatly into tight spaces without cluttering your desk or rack. The device weighs 15.6 ounces, which keeps it light enough for easy placement but sturdy enough to remain stable during operation. The exterior finish is gray, providing a neutral look that blends with most modern electronics. You do not need to worry about it standing out as an eyesore in your home office.
The internal construction relies on a Li-ion battery chemistry, which is standard for this type of backup power solution. This choice supports the 120W DC output capability, ensuring your NAS receives consistent power during outages. The unit operates quietly, meaning you can keep it running in the background without noise interference. Its compact design is intentional, allowing it to stack or sit directly next to compatible UGREEN models like the DXP2800 or DXP4800. This integration helps maintain a clean cable management setup. Since the device is specifically built for select UGREEN NAS models, the physical layout is optimized for those connections. You get a straightforward, no-frills hardware experience focused on reliability and space efficiency.
Setup and Daily Operation
Setting up the UGREEN US3000 requires careful attention to device compatibility before you begin. The unit is designed exclusively for select UGREEN NAS models, including the DXP2800, DXP4800, DXP4800 Pro, DXP4800Plus, DXP480T, DH4300Plus, and DH2300. It is explicitly not compatible with the DXP6800 or DXP8800 series. You must verify your NAS model name against this list to ensure proper function. Once you confirm compatibility, the physical installation is straightforward. The unit’s compact dimensions of 8.07 inches in length, 5.31 inches in width, and 1.46 inches in height allow it to sit neatly alongside your storage device. Its 15.6-ounce weight and gray finish support a clean, unobtrusive setup.
In daily use, the UPS provides uninterrupted power through its 12000mAh Li-ion battery. During a power outage, the unit transfers power in zero seconds, preventing potential damage to your NAS and internal hard drives. This brief backup time, roughly ten minutes, allows you to save data or shut down the system safely. You can configure operational policies via a dedicated app. The built-in intelligent processor monitors power status and can automatically pause active tasks or notify you to shut down the NAS. When electricity returns, the unit automatically restarts your NAS without manual intervention. The device operates quietly, ensuring it does not disturb your work or sleep. It also includes multiple protection protocols, such as surge, over-charge, and short-circuit protection, to keep your data secure during unstable power conditions.
Check Compatibility Before Buying
Before you buy the UGREEN US3000, verify your NAS model against the supported list. This unit works only with specific 2-bay and 4-bay UGREEN devices like the DXP2800 and DH2300. It is incompatible with the DXP6800 and DXP8800 series. Ensure your current setup matches one of the approved models to avoid wasted investment. You should also confirm your NAS power draw stays under the 120W DC output limit. The 12000mAh Li-ion battery requires minimal upkeep, but you should monitor its health over time. This UPS fills a niche for users who need seamless power transfer without complex configuration. Unlike general-purpose units, it integrates directly with UGREEN’s app for automated shutdowns. If you own a supported NAS, this dedicated backup offers a clean, quiet solution that fits neatly beside your storage device. It simplifies data protection for home offices by preventing sudden power loss damage.
Check before you buy
- Verify your NAS model is in the supported list.
- Confirm power draw stays under 120W output limit.
- Ensure you use the UGREEN app for automation.
- Check for DXP6800 or DXP8800 incompatibility.
