Review of the UGREEN NAS UPS – Is the US3000 120W UPS Any Good?

The UGREEN US3000 is a 120 W DC uninterruptible power supply developed specifically for UGREEN NAS devices that rely on an external DC power brick. Unlike conventional UPS systems that convert AC to DC, this model outputs direct 12 V DC power with a zero-second transfer time, ensuring there is no interruption during a power loss. It is equipped with a 12,000 mAh lithium-ion battery pack made up of four 3000 mAh cells, providing a rated energy of 43.2 Wh and up to around ten minutes of backup time depending on workload. Measuring 120.6 × 80.5 × 29.6 mm and weighing approximately 439 g, the US3000 is compact enough for desktop environments where space is limited. Beyond supplying short-term emergency power, it integrates with UGOS Pro software via a USB communication cable, allowing automated shutdown, timed standby, and restart once power is restored. This focus on seamless hardware and software compatibility makes the US3000 notable for users running UGREEN NAS systems that need to mitigate risks of data corruption caused by sudden outages.

UGREEN US3000 UPS Review – Quick Conclusion

The UGREEN US3000 is a purpose-built DC UPS that prioritizes seamless integration with UGREEN NAS systems over broad flexibility. Its compact aluminum chassis houses a 12,000 mAh lithium-ion battery pack capable of delivering 120 W output with zero-second transfer time, ensuring that a connected NAS continues running long enough to perform a safe shutdown. Unlike traditional AC-based UPS units, it avoids conversion inefficiency by supplying direct DC power, while its USB link with UGOS Pro enables automatic shutdown, timed standby, and restart functions. Testing confirmed reliable operation across scenarios from immediate power loss to scheduled shutdowns, with system logs capturing events in under two seconds. However, its design is deliberately narrow in scope: it supports only one NAS at a time, does not extend to routers or switches, and offers limited runtime of around ten minutes under load. For users operating within the UGREEN ecosystem, it provides an efficient and well-integrated safeguard against data corruption during outages. For those needing multi-device protection or long-duration backup, its constrained design and compatibility limit its broader applicability.

Why the UGREEN US3000 UPS is Important/Interesting

Uninterruptible power supplies are not new, but most consumer models are designed for general computing and rely on bulky lead-acid batteries with AC pass-through. The UGREEN US3000 differs by offering a DC-to-DC solution that matches the external power design of UGREEN NAS units. This means it eliminates the inefficiency of double conversion and avoids the audible transfer delays that can occur with traditional UPS hardware. With a 120 W output ceiling, it is tailored for single-device use rather than multiple systems, but that specificity ensures closer integration with the NAS’s power and shutdown controls. From a technical perspective, its lithium-ion battery pack offers greater energy density than lead-acid, allowing the device to remain compact while still covering several minutes of safe system operation during an outage.

The importance of this UPS becomes clearer when examining how it interacts with UGOS Pro. Unlike generic solutions, the US3000 communicates directly with the NAS operating system via a USB connection, exposing monitoring and automation options in the control panel. Users can configure automatic shutdown after a set period, trigger standby to conserve remaining charge, or enable auto-restart once mains power returns. These features are not just convenient but directly address the risks of corrupted writes, incomplete backups, or damaged RAID arrays during sudden power loss. Given that UGREEN NAS systems are designed for small offices and home use, where environments may not include larger enterprise-grade UPS equipment, the US3000 effectively bridges that gap by offering a purpose-built, compact, and integrated safeguard.

UGREEN US3000 UPS Review – Design

The UGREEN US3000 follows a compact, rectangular form factor with dimensions of 120.6 mm in length, 80.5 mm in width, and 29.6 mm in thickness. Its weight of just under 440 g makes it relatively lightweight for a UPS, reflecting its focus on portability and single-device deployment rather than large-scale power protection. The outer chassis is made from anodized and sandblasted aluminum alloy, which gives it improved durability compared with plastic housings and also aids in passive heat dissipation. The choice of materials ensures a consistent finish that aligns visually with UGREEN’s NAS enclosures, providing an integrated appearance when the two devices are used together on a desktop.

Connectivity is handled entirely through DC and USB ports positioned on a single side of the device. The panel includes a DC input, a DC output, a USB-C port for data communication, and a power button. The fixed DC cable has a length of approximately 28 cm, while the included USB-A to USB-C cable measures around 53 cm, allowing flexible placement next to a NAS system without excess cabling. Each port and control is clearly labeled with printed icons, reducing the likelihood of incorrect setup. Unlike conventional UPS systems that feature multiple AC sockets, the US3000 focuses on a single dedicated output, reflecting its intended role as a companion unit for UGREEN NAS models rather than a general-purpose UPS.

The packaging of the device mirrors UGREEN’s approach with its NAS line, offering clear product imagery and specification highlights on the box exterior. Inside, the unit is provided with a base stand for stable positioning, the aforementioned data cable, and basic documentation. This is a minimalist package compared to conventional UPS units, which often include multiple adaptors or accessories, but the streamlined approach ensures that setup remains straightforward for the intended NAS integration. The inclusion of a stand is particularly useful given the slim design, as it helps keep the UPS stable in vertical placement while maintaining airflow around the chassis.

From a design perspective, the emphasis is on simplicity and integration rather than flexibility. The device does not feature multiple voltage outputs, nor does it support powering unrelated devices such as routers or switches. Instead, its DC pass-through design, small footprint, and single-device orientation mark it as a specialized tool. This aligns with UGREEN’s approach of building a controlled ecosystem around its NAS systems, where accessories are engineered for direct compatibility. The US3000 therefore sits between consumer-grade battery packs and enterprise UPS units, offering a focused solution that fits into a narrow but clearly defined usage scenario.

UGREEN US3000 UPS Review – Internal Power Design

Inside the UGREEN US3000 is a straightforward but carefully constructed layout built around a 12,000 mAh lithium-ion battery pack. The pack consists of four SunPower INR18650-3000 cells, each rated at 3000 mAh and 11.1 Wh, connected in series to deliver a combined rated energy of 43.2 Wh at 14.4 V. The cells are wrapped in foam insulation and secured with adhesive to minimize movement, with spot-welded nickel strips linking them. Additional barley paper insulation is applied around the terminals for added protection. This design choice allows the UPS to maintain compact dimensions while ensuring sufficient runtime for controlled NAS shutdowns.

Battery management is handled by a Chipsea CBM8580KV6NT protection IC. This chip monitors voltage, current, and temperature across the pack, ensuring safe charging and discharge cycles. It communicates with the system host via SMBus 3.1, which enables the UPS to relay real-time status to the NAS when connected through USB. Supporting components include current sense resistors, thermistors, and MOSFETs for switching and power regulation. Together, these ensure not only that the battery operates safely but also that the UPS can reliably deliver 120 W maximum output without voltage instability.

Voltage conversion is performed by a dual-stage arrangement. A Texas Instruments TPS55289 synchronous buck-boost converter handles a wide input range up to 30 V and can output between 0.8 V and 22 V. Alongside this, a SouthChip SC8002 synchronous buck controller manages current limiting and efficiency across dual channels. Power MOSFETs from CR MICRO and NCEPower are used for pass-through control and output switching, while a GigaDevice GD32F303RCT6 Cortex-M4 microcontroller coordinates the overall system, including communication with the NAS. Passive cooling, adhesive reinforcement on inductors and capacitors, and fuses at both input and battery ends further underline the design focus on stability and safety.

UGREEN US3000 UPS Review – Testing with UGREEN NASync Systems

To evaluate the UGREEN US3000, three operational scenarios were simulated: immediate power loss with continued operation, automatic shutdown under UPS control, and timed shutdown with automatic restart when power returned. In each case, the NAS was connected to the UPS using both the DC input and USB communication cable to ensure full integration with UGOS Pro. The first test involved disconnecting mains power to replicate an outage. The NAS continued running without interruption, with the transfer to battery occurring instantly. System logs registered the event in under two seconds, and normal file access, media playback, and downloads remained available until the battery level dropped to the configured threshold.

In the second test, the system was configured to shut down automatically as soon as the UPS switched to battery mode. Once power was removed, the NAS immediately began its shutdown process. This test showed that the UPS integration with UGOS Pro allowed a fast and orderly shutdown sequence, preventing data corruption or incomplete writes. The reaction time was near instantaneous, and the system was powered down safely without user intervention. This mode may be best suited for environments where uptime during an outage is less critical than ensuring rapid data protection.

A third test focused on timed shutdown, with the UPS set to keep the NAS running for five minutes before initiating a safe power-off. Once mains power was disconnected, the NAS continued operating for the specified period, then shut down as configured. After power was restored, the UPS automatically triggered a restart of the NAS, returning it to full operation within a few minutes. This confirmed the UPS’s ability not only to handle outages but also to manage recovery without manual restart, which is beneficial for users who may not be present during a power failure.

During all tests, the device’s limitations became apparent. With a 120 W maximum output and battery capacity limited to 43.2 Wh, it cannot sustain extended operation. Its role is restricted to ensuring controlled shutdowns and short bridging periods rather than providing long-term backup. Furthermore, it supports only one NAS system via DC pass-through, so it cannot protect additional hardware such as routers or switches. Nevertheless, within its defined parameters, the UPS consistently delivered seamless transitions and executed software-triggered events reliably, confirming that its functionality matches its intended scope.

UGREEN US3000 UPS Review – Conclusion & Verdict

The UGREEN US3000 fills a specific role: protecting UGREEN NAS devices from sudden power loss. Its design avoids the bulk and inefficiency of conventional AC-based UPS units by delivering DC pass-through power with zero transfer time. In practice, it provides just enough runtime for the NAS to perform a controlled shutdown, while its software integration ensures automation of both power-off and restart processes. With lithium-ion cells, a compact aluminum chassis, and close alignment with UGOS Pro features, it is engineered as a dedicated accessory rather than a universal power backup solution.

As a result, its usefulness is limited to scenarios where a single UGREEN NAS is the priority. It does not offer multiple outputs or extended backup duration, making it unsuitable for wider network coverage or enterprise requirements. Instead, the US3000 should be viewed as a narrowly focused safeguard that addresses one problem reliably: preventing data corruption and incomplete writes during outages. For users within the UGREEN ecosystem, it is an effective solution, but for broader applications, its scope remains intentionally constrained.

      8. I’ve got this device. I have it configured auto power down on power loss (just for testing purposes) and have wake when power is provided, but it isn’t turning the device on as expected. Any tips?

        Edit: apparently even though this power option is available in the settings in the mobile app, applying it does not work from there. When I did it on my computer, and a hit apply, it worked.

      14. Why not incorporate it into the storage boxes themselves? Further, one could want a larger UPS that can handle soft power down for both main computer and NAS. Or software in the Computer’s OS that powers down a NAS softly before powering itself down. My APC UPS will pull power on my PC but I’m not aware that I could control other devices in a similar way. Why need a separate UPS for each? But indeed, this does seem a good thing. Could UGreen provide apps to run on Synology and other company’s products?

      36. My advice is just buy a standard ups that can power a few devices (as many as you need) for protection alone.

        This won’t help you in the middle of a read/write in most cases unless you have a laptop and even then its no good if your router/network switch is down and you can apply some logic from then on.

        Get a universal ups that can power your NAS plus your router and network switch if you have one at minimum even if just for protection from spikes and avoid sometimes troublesome reboots from your network/internet.

      45. Just to point out, not specific to this device, the hosts writing to the Nas need to be shut down first or data corruption can/will still happen. Graceful shut down of the Nas while it’s still being written to is essentially the same as no UPS. Looks like it has the option to be a Nut server so make sure your other guests connect to this so they can be shut down first. NAS needs to be the last to turn off.

      48. Please excuse my ignorance but i thought all nas’s had the provision to shut down & re boot the system safely ( in the event of a power failure)so as not to lose or corrupt data on the drives.
        My Drobo 5N has had this from day one.
        Admittedly it’s just used to store my movies & CD music collection (so nothing critical if lost). Why don’t other manufacturers have the same feature.
        It seems to me to be a basic necessity for when storing data. ????
        Of course, if my power goes down, then so does my broadband so to carry on working on my laptop would also not be possible.

      55. Sold out everywhere. It would be interesting to see if it would work with Asustor (AS-604T) and Synology (DS420J) NASes. Home use only for data, photos and videos, and like the review for the Ugreen, all I need is for it to keep the NAS alive during a power glitch (stormy weather), or to gracefully shut them down in the event of a prolonged power outage.

      58. One big thing for me is that it’s significantly more power efficient than a normal ups. The inverter stage converting ac to dc for the batteries, then dc to ac for the plugs, then the ups converts that Back to dc again for use… so much wasted power with a normal ups! This skips most of that finally.

      82. All of the mentioned functions have been possible for years with a compatible UPS connected to a Synology NAS via USB. The NAS can even communicate the UPS status to other devices via SNMP – for example, to a backup NAS. If both NAS devices are connected to the same UPS, they can be shut down automatically when the remaining energy is low. Additionally, any device can be plugged into the UPS.

      83. Form factor is really good, battery capacity not so much but it’s more than enough for a single NAS for a few minutes and to shut down safely if necessary. The price, okay, we’re equivalent to the entry level of Aeton and APC but with much less battery capacity. Why not, in a 10″ rack.

      84. One thing wat good is with this solution is no extra energy loss. Now only one time from ac to dc. With a regular ups its ac to dc back to ac and then to dc . Each step means energy loss.

      87. As UGOS continues to mature, and they keep pulling wins like this, it’s becoming harder and harder to find reasons NOT to just go with a UGREEN NAS!

      90. Ugreen employees: please, PLEASE make a USB power bank like this. I have been wanting one for years. If you can make it with the ability to charge the battery while also providing power to USB ports, even better!

      91. They sell them on Amazon UK now, got mine the other week, love it! Love my UGreen NAS, love my UGreen desktop charger too. This company just seems to actually care about their customers experience of their products.

      92. Thank you for your review! I looked at this UPS a couple of times but I had a few doubts, your video makes a good explanation.
        The only remaining problem is that this particular UPS is impossible to buy in Europe at the moment ????

      94. Perfect, would be great if they brought out a generic version that works with a Synology. This is exactly what I need, I don’t want a massive rectangular box with 8 sockets just to safely shut down the nas!

      97. Before it existed I had to pay 150 for my UPS. It holds my Synology, Optic Fiber router and Wireless Router because, let’s be honest, if there’s a power outage, without your wireless/internet you have nothing unless you plug yourself in.
        Again, pretty cool and I’ll probably think about it on my next implementation

      98. This is really cool.

        I’d love to see a NAS with a *built-in* UPS that’ll keep it running for 5-10 minutes then shut down. With an easily replicable battery. Sounds like we’re on track for that now that someone has hit the market with something purpose built.

      101. I bought my Ugreen NAS a month ago, and when i heard about this UPS i tried to buy it ASAP, well i took a bit to be available again, but is arriving next week, had a disk that failled in a power outtage with my last nas setup, hopefully never more.
        if you had your video released a week earlier…

      104. Only problem is I’ll have to buy 2 for my Ugreen NAS devices! Currently £89 on Amazon, but maybe Black Friday will give us something slightly better.

        Currently unavailable on both Amazon UK and Amazon US. The AliExpress listing doesn’t state Ugreen, and is £82 + £42 shipping! Ugreen need to sort out the supply of this really.

      109. I prefer to use my APC BX750MI UPS to power my Synology DS423+ and 8 port 2,5 Gbit switch. The NAS has an USB connection to the UPS so it can power off in time when the power runs out. In my trial test I managed to use the NAS on full power (write and read sequence actions) for over 90 minutes before the NAS powered down. That is not something you can achieve with this product. Ok, it can sense the power off state and signal the Ugreen NAS to power down, but you will not achieve long battery powered activity on such a whimpy small UPS.
        On your line at 1:04 why no one in the NAS world has created an UPS until now: UPS makers are better in making UPS’es and NAS makers better in NAS making. I don’t feel the need or urgency to have all my IT gear from the same manufactory: I choose what suits me best for every need I want to be met by an IT product. This is spoken by a IT professional with 28 years of experience.

      118. Hi
        I was checking the spec for this UPS for long time. It would be great if you could help me with something I’m confused with ????

        It said it can take 12-19V as intake then out put with 12V.
        but DXP 4800+ needs 19V to operate and it completely compatible as listed.

        So my question is
        A. Will the UPS out put 19V when 19V is provided as power source.
        Or B. DXP 4800+ can operate in 12V.

        It would be great if you could help me untangle the mystery
        ????
        Thanks

      122. In general it is good idea. What I would like more even it would cost more is to have replaceable battery. I bought a powerbank 6 months ago, but with experience of other people I went in way to buy 21700 battery’s and bought 100w empty powerbank so when one of those 2 dies I can just buy it rather then dispose of complete powerbank (no one recycle them in reality). And it would be nice to offer multiple size battery and cases because if you put 7200rpm hdds they can draw a lot of power

      124. I can hardly think of a real use case for this UPS, even when one has a compatible NAS. Your other network devices (modem, router, switch) require UPS protection from surges and power loss. A single dedicated UPS can be bought for less than a double the price of this Ugreen UPS and serve multiple devices for longer than 10 minutes. Other well-known NAS brands offer shutdown options during power loss within their respective OSes. I fail to see what all excitement is about.

      125. 7:34 “this device will only help you in the event of supplying 1200 milliamps of power (?) to your NAS”.
        milliamps are not power. milliamps are current.
        you’ll get power by multiplying with voltage.
        i don’t know where the figure of 1200 milliamps comes from, if you supply only 1200 milliamps (1.2 A) – it will DEFINITELY NOT HELP you.
        because it’s input REQUIREMENTS are either 12 V 10 A/ 19 V 7.9A / 20 V 7 A (notice the figure for current there 😉 )

        “1200 milliamp battery inside with 4×3000 milliamp lithium modules …”
        something tells me you’ve lost one zero somewhere. (it’s also milliamp-HOURS)
        and on the other note – i’d think it’s more common to specify the capacity of devices like UPS or power stations in Wh – it eliminates the need to keep track of voltages. (and you’d less likely miss a zero there 🙂 )

      127. *THIS!* I’ve been researching what to get as my first NAS.
        I was wondering what kind of UPS to use.
        Sounds like Ugreen just jumped to the top of my list, jumping right over a Qnap model I’ve been considering.

      130. Hmm … not quite sure why this is so exciting. I mean, there are other UPS’s this will work with (I presume). Not knowing the level of support UGOS has for third-party UPS’s, I can’t say if this is so or not. One would hope that UGOS has support for major UPS brands like APC. If not, then I’m hoping UGreen isn’t starting to go down the Synology road of providing brand-specific solutions by excluding support for third-party alternatives.

        Also, not quite sure why you’re gushing over functionality that is standard for any decent UPS. While this unit is compact, it’s pricey considering its inability to power any other devices. My APC unit can power 8 three-pin connected devices, has both USB A and C charging ports, LCD status screen and battery health monitoring and has all the functionality you praise with the UGreen UPS, and only cost £20 more.

      133. My biggest issue with power are the so-called brown-outs. Power is lost only for a couple of seconds, or voltage may drop below a critical value. When put in the auto-shutdown mode, will it cancel if power returns (even after a couple of seconds)?

      134. The ideal UPS for a NAS would be, when the last HDD-Slot would have aditional connectors intern for slide in a UPS-Modul instead a HDD. So you can have 4xHDD or 3xHDD + 1xUPS. All without cable mess. (hope this was understandable, I am from Germany and do not often speak/write english ????)

      135. Let’s be honest: most UPSs are expensive, often smell unpleasant, can be noisy, and you have to worry about them setting your place on fire or failing after a short time and no longer protecting your NAS properly. All of this (in addition to the noise that many NAS devices make) can quickly turn the dream of having your own cloud into a nightmare.
        Every small laptop or smartphone has a built-in UPS. So why not the NAS? This little device from Ugreen is a good compromise, as you can replace it at any time, even if you keep the NAS itself for a long time.

      141. Whata great idea. On first look, I assumed this REPLACED the existing NAS PSU. Even if it needed to be a bit bigger to contain the aditional components, that woud have been even more impressive.

      147. For inexpensive NAS solutions for home and small business, it at least gives some functionality as a battery backed write cache to complete transactions and gracefully shut the unit down in the event of a power failure. Great idea and simple in-line implementation.

      148. it seems like just like those router ups with 3 x 18650… have to say, battery last lower than normal ups and, in my experience (i don’t know this device), you know they are depleted next time you need them. nice device however. too much expensive imo.

      154. I wonder why NAS brands never tried to make one of those. It’s steady income because lithium-ion battery wears off over time way much faster than NAS and HDDs.
        Nice job Ugreen. Really.

      158. Recently added a UPS (now 2!) to my setup. Went with Goldemate 1000VA units and the little Ugreen DXP2800 knew just what to do with it. It’s now my NUTS server so the big server running TrueNAS will also power down. The first UPS worked out so well I picked up a 2nd one to power the cable modem, router, switch etc. Some day I might even figure out how to get the Mac Studio to listen to the NUTS server. 🙂

      160. Makes sense if it’s not in the same location as your switch and router. You’ll still want a router for those to keep the network up and to reduce the chance a power surge comes down the Ethernet cable.

      162. I love my QNAP, but dang… This is brilliant, and I wish QNAP made one! Right now, I have my QNAP devices plugged into an APC UPS, and it’s “dumb”, so the idea of built-in first-party power management is a dream come true! Right-on, UGREEN!

      163. I get that this is great for Ugreen consumers, but I’d be wary of recommending this as it forces buyers into a sort of Ugreen walled garden. Obviously this isn’t as egregious as having NAS units that demand specific drive purchases, but it’s a matter of degree, not a matter of kind.
