Your needs, this model
Does it fit your priorities?
Does the DXP2800 + UPS3000 bundle include storage drives?
No. UGREEN labels the NAS as diskless and says storage disks are sold separately; the UPS is an accessory, not a drive. Its 80 TB headline describes a maximum raw configuration across two SATA and two M.2 positions, not shipped capacity.
Explore this need in the finder →Which UPS is included and does UGREEN document it for the DXP2800?
The current U.S. selector names the package DXP2800 + UPS3000. UGREEN's US3000 accessory page lists 120 W maximum output and a 12,000 mAh battery, and its NAS UPS guide confirms DXP2800 compatibility. Check the exact bundle contents and use the NAS's original adapter; do not infer a specific runtime from the battery label.
Explore this need in the finder →Will this DC UPS keep the router and switch online too?
Not by itself. UGREEN describes the US3000 as an inline DC unit for a compatible NAS and gives a USB data link for monitoring. A router or switch plugged into ordinary wall power needs its own suitable battery-backed supply if it must remain online; test UGOS detection and the configured safe-shutdown sequence under your real load.
Explore this need in the finder →This research-based review covers the U.S.-listed UGREEN NASync DXP2800 + UPS3000 bundle, not a bench test or an estimate of real outage runtime. The package pairs the two-bay DXP2800 NAS with UGREEN's US3000/UPS3000 DC battery unit. That is a real functional difference from the diskless base NAS, but it does not add storage, network ports, or power for the rest of a home network.
The NAS remains a two-bay, diskless DXP2800
The bundle's storage and network limits are still those of the DXP2800: two internal SATA bays and one built-in 2.5GbE connection. It also has two M.2 NVMe positions and an Intel N100 processor with listed 8 GB DDR5 memory, expandable to 16 GB. Those M.2 positions are separate SSD storage or caching options; they do not increase the count of SATA drive bays. UGREEN's 80 TB collection headline combines two 32 TB SATA drives and two 8 TB M.2 SSDs as maximum raw installed capacity. None of those drives is part of this bundle, and that raw total is not an 80 TB mirrored volume. With two compatible SATA drives supplied by the buyer, the DXP2800 can be set up in RAID 1. UGREEN lists Basic, JBOD, RAID 0 and RAID 1 for its two-bay models. The owner still selects the drives, creates the pool and checks the smaller drive's capacity as the practical ceiling before overhead. RAID 1 can preserve access after a single member failure when the array is healthy, but it is not an independent backup. The UPS changes the power-loss story, not the backup story: retain a second copy somewhere outside this NAS.What the included US3000 changes
The distinction is specific, not generic: UGREEN's U.S. selector labels this package DXP2800 + UPS3000, and its accessory page identifies the US3000 with up to 120 W output, a 12,000 mAh battery, 43.2 Wh rated energy and a USB data connection. UGREEN's setup guidance lists the DXP2800 as compatible with the US3000. A zero-second transfer claim describes the UPS switching characteristic, not a guaranteed time for this NAS to remain running. Runtime varies with the installed drives, activity, battery condition and shutdown settings, so a capacity label should not substitute for a test under your load. The unit is a DC UPS for a supported NAS power path, not a multi-outlet AC UPS for an entire desk. UGREEN's wiring instructions use the DXP2800's original power adapter and connect the UPS to the NAS by its DC output; a USB data cable lets the NAS monitor it. After setup, confirm that UGOS detects the unit and configure the desired safe-shutdown behavior. Test the full sequence before depending on it, and repeat that check after changing drives, firmware or power settings. A router or switch still plugged into ordinary wall power may shut off during an outage. If the NAS needs network communication while running on battery, power those upstream devices separately too.Bundle value depends on your power and storage plan
This package is easier to assess as two decisions bundled together: a diskless two-bay NAS and a dedicated compatible UPS. It suits a buyer who already wants the DXP2800's bay count and 2.5GbE link and prefers to receive the matching power unit in the same selected package. It is less compelling if you only need a different NAS, a longer whole-network backup window, or a battery system that also powers a router, switch and client. It should not be compared with an AC UPS by battery mAh alone; the output path and protected equipment are different. UGREEN lists DXP2800 compatibility for US3000, but that does not calculate your runtime or guarantee every third-party power configuration. The seller's package selector and the accessory compatibility list are separate checks: confirm the order says UPS3000, verify the exact NAS and UPS revision, and use the adapter specified by UGREEN. The bundle does not mean that the NAS is pre-configured, that storage drives are included, or that the UPS has been set up for shutdown.Checks to make before buying
Confirm the exact DXP2800 + UPS3000 entry in the order summary instead of relying on a category card that may abbreviate the package. Check that the box includes the US3000 and its data cable; keep the NAS's original adapter for the documented connection. Decide which compatible SATA drives will populate the NAS, verify each full model on UGREEN's compatibility list, and calculate RAID 1 usable space from the smaller drive rather than the 80 TB raw headline. Finally, decide whether the router and switch also need battery power, set the UPS monitoring and shutdown plan in UGOS, and run a controlled outage test before placing important data on the system. This bundle adds a documented DC backup component; its practical value depends on those setup choices, not on an assumed runtime.Key specifications
