Overview
UGREEN NAS owners get a matched battery backup that powers the storage box and links to it over a USB cable. The flat compact case rests beside the NAS on a shelf or desk.
Matching the backup to the NAS is its strength, with a compatibility list of specific UGREEN models and a USB link between the two. Routers, modems and other NAS brands have no listed support, and the listing does not publish runtime.
Who it's for
Suited to a home or small office running one of the listed UGREEN NAS models on a shelf with limited space. Owners of other NAS brands, or anyone who needs AC outlets for more gear, should look at a conventional UPS.
Pros and cons
- Matched to specific UGREEN NAS models
- Compact, flat case
- USB link to the NAS
- Two year warranty
- Runtime not listed
- Only UGREEN NAS models on the compatibility list
- Compatibility lists differ between spec fields
Performance notes
Runtime depends on the NAS power draw against a fixed battery capacity, so a fuller drive bay and heavy activity shorten it. Because the listing pairs the unit with named UGREEN models over a USB cable, behavior on any other device is unknown.

Frequently asked questions
How does the UGREEN US3000 connect to the NAS?
The listing names a USB connector on its cable and lists the supported UGREEN NAS models. It does not detail the power plug, so confirm your NAS is on the compatibility list before installing.
Can I plug a router into the UGREEN US3000?
The listing shows no AC outlets and names only UGREEN NAS models as compatible devices, so do not plan on it for a router or modem.
