I remember it vividly. I was in the middle of a crucial client presentation, sharing my screen on a video call, when my apartment plunged into darkness. The lights went out, my monitors went black, and the most deafening silence of all was the sudden absence of the internet. My Wi-Fi signal was gone. In that instant, I was completely cut off, not just from my client, but from my entire work ecosystem. The frantic fumbling for my phone to tether a connection, the apologetic emails sent too late—it was a professional nightmare. This single experience highlighted a stark reality of modern life: our productivity, our communication, and even our entertainment are utterly dependent on a stable internet connection, which in turn depends on a stable power supply to a small, unassuming plastic box: our router.

What to Consider Before Buying a Mini DC Uninterruptible Power Supply
An Uninterruptible Power Supply (UPS) for your router is more than just a battery; it’s a key solution for maintaining digital normalcy in a world of increasingly frequent power glitches and outages. Traditional UPS systems are large, heavy, and designed to power AC devices like desktop computers. However, for low-voltage DC devices like routers, modems, and network switches, these are inefficient overkill. A dedicated mini DC UPS like the SKE SMART KEY ENERGY 10400mAh UPS for Router is purpose-built to provide direct, efficient DC power, ensuring your internet gateway remains online, your smart home devices stay connected, and your work-from-home day proceeds without a hitch. It’s the bridge over the digital chasm created by a power cut.
The ideal customer for this type of product is someone who relies on constant connectivity. This includes remote workers, smart home enthusiasts, online gamers, and anyone living in an area with an unstable power grid. If a ten-minute power outage causes you significant disruption—from losing unsaved work to having to manually reboot and re-sync a dozen smart devices—a mini DC UPS is an essential investment. Conversely, it might not be suitable for those who need to power high-wattage AC devices like a gaming PC or a large server. For that, a traditional, larger UPS would be the necessary choice. For those simply looking to charge a phone, a standard power bank would suffice, though this device can also perform that function admirably. You can explore its full range of capabilities here to see if it fits your specific needs.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Unlike their bulky AC counterparts, mini DC UPS units are designed for discretion. Measure the space in your media cabinet or behind your desk. The SKE unit’s compact footprint (182 x 107 x 32 mm) is a significant advantage, allowing it to be tucked away or even wall-mounted, a feature we found particularly useful for clean, organised setups.
- Capacity & Runtime: Capacity, measured in milliamp-hours (mAh), determines how long the UPS can power your devices. The 10400mAh battery in this SKE model is substantial. To estimate runtime, you need to know the power draw (in watts) of your router and modem. For example, a typical router/modem combo drawing 12 watts can be powered for over 2.5 hours, a duration that covers the vast majority of common power outages.
- Voltage & Port Compatibility: This is perhaps the most critical factor. Check the power adapter of your router, modem, ONT, or network switch. It will specify the required voltage (e.g., 9V or 12V) and the plug size. The SKE unit excels here, offering two 12V DC ports, one 9V DC port, and a 5V USB port, making it exceptionally versatile. It also includes various Y-cables to connect multiple devices.
- Ease of Use & Maintenance: A good mini UPS should be a ‘set it and forget it’ device. The SKE model is exactly that. You plug it into the wall, connect your devices to it, and it manages everything automatically, switching to battery power instantaneously when the mains fail. The LED indicators provide a clear, at-a-glance status of battery level and operation mode, requiring zero technical intervention.
This specialised approach is what sets a device like this apart from the broader market of power protection.
While the SKE SMART KEY ENERGY 10400mAh UPS for Router is an excellent choice for its specific purpose, it’s always wise to see how it stacks up against the competition.

First Impressions: A Compact Powerhouse Ready for Duty
Unboxing the SKE SMART KEY ENERGY 10400mAh UPS for Router, the first thing we noticed was its solid, reassuring feel. Weighing just under half a kilogram, it has a density that speaks to the four lithium-ion battery cells packed inside. The casing is a durable matte black plastic that resists fingerprints, with a glossy black strip across the top housing a series of intuitive LED indicator lights. It’s a clean, unobtrusive design that doesn’t draw attention to itself.
Inside the brightly coloured box, alongside the unit itself, we found the necessary accessories to get started immediately. This included the mains power cord and, crucially, two different “Y” cables. These splitter cables are a thoughtful inclusion, allowing one output port to power two devices, provided their combined power draw doesn’t exceed the 2A limit. As one user noted, these cables are generously long, which made reaching a router on one shelf and a network hub on another a breeze. Our only initial critique, mirroring some user feedback, was the relatively short mains lead (around 80cm), which might limit placement options depending on your socket layout. Setup, however, was as simple as it gets: plug it in, connect your devices, and press the single power button. It was up and running in under a minute.

A Deep Dive into the SKE Mini UPS’s Real-World Performance
A product like this lives or dies by its performance during a crisis. It’s not about flashy features; it’s about absolute reliability when the lights go out. To that end, we put the SKE SMART KEY ENERGY 10400mAh UPS for Router through a series of rigorous tests simulating the exact scenarios it was built to handle. We connected it to a common home network setup: a BT Openreach Fibre ONT (Optical Network Terminal) and a standard ISP-provided Wi-Fi router. What we found was a device that not only meets but exceeds expectations for its intended role.
Seamless Power Transition and Impressive Runtime
The single most important function of a UPS is the switchover. When mains power is lost, the transition to battery power must be instantaneous, otherwise the connected devices will still reboot, defeating the entire purpose. We simulated a power cut by yanking the SKE’s plug directly from the wall socket. The result was flawless. There wasn’t so much as a flicker in the status lights on our router or ONT. Our video stream continued without a single dropped frame, and a file transfer in progress didn’t miss a beat. The switch is truly uninterruptible.
With the unit running on its battery, the next question was runtime. The 10400mAh capacity sounds impressive, but what does it mean in practice? Our test setup, consisting of the ONT and router, had a combined power draw of approximately 12.5 watts. Based on our calculations and real-world testing, the SKE SMART KEY ENERGY 10400mAh UPS for Router powered both devices continuously for just under three hours. This duration is more than sufficient to outlast the vast majority of residential power outages. Several users reported similar results, with one calculating a runtime of over 2.5 hours for their 12W load, confirming our findings. For those who work from home, three hours of uninterrupted internet is the difference between a minor inconvenience and a day of lost productivity. It’s also worth noting that the unit is completely silent. There are no fans, no humming, just quiet, reliable power, which is a massive advantage over larger, fan-cooled UPS systems. It’s a feature that really sets it apart for quiet home and office spaces.
Unmatched Connectivity Hub for Low-Voltage Gadgets
What truly elevates the SKE Mini UPS from a simple battery backup to a central piece of network infrastructure is its array of output ports. While many competitors offer a single 12V output, SKE has provided a comprehensive solution. Having two separate 12V/2A DC ports, one 9V/2A DC port, and a 5V/2A USB port is a game-changer for anyone with a slightly more complex setup. We found this incredibly useful, echoing the experience of a user who needed to power a router and two separate smart home hubs.
In our tests, we were able to simultaneously power our 12V fibre ONT, a 12V mesh Wi-Fi access point, and a 9V Ethernet switch, all from the same compact unit. This ability to consolidate power for all your essential network gear is its killer feature. It eliminates the mess of multiple power adapters and ensures your entire network core—not just the router—remains online. One user perfectly described how it solved their problem of smart devices failing to reconnect after a power cycle because their Ethernet switch would lose power. The SKE unit prevents this entire cascade of failures. The addition of the USB port also means you can keep a critical security camera powered or charge your smartphone during an extended outage, adding another layer of utility and peace of mind. This multi-device support makes it an invaluable tool for creating a truly resilient home network.
Thoughtful Design and User-Friendly Operation
Beyond its technical prowess, the physical design and usability of the SKE Mini UPS are well-executed. Its compact, rectangular form factor allows it to be placed vertically or horizontally, fitting into tight spaces where traditional UPS units would never go. A standout feature we appreciated are the two keyhole-style mounting hooks on the back. This allows the unit to be securely mounted to a wall or the inside of a cabinet, getting it off the floor and creating a very tidy, professional-looking installation.
Operation is governed by a single button and a series of clear, bright LEDs. Four blue LEDs give a precise indication of remaining battery capacity (25%, 50%, 75%, 100%), so you’re never left guessing. Three separate status LEDs show whether the unit is running on mains power (Work), on battery (Backup), or if there’s an issue (Fault/Overload). This simple, visual feedback is all you need. We did note the audible beep it emits when it switches to battery power. While this is a useful alert, some may find it intrusive, though it’s a common feature on UPS devices. One user did make a valid point about safety, noting their supplied UK plug came with a 13A fuse, which they correctly replaced with a 3A fuse for a device with a 1A rated input. This is a wise precaution for any user to take. Overall, from its versatile port layout to its wall-mountable design, the SKE SMART KEY ENERGY 10400mAh UPS for Router is a product that has clearly been designed with the end-user’s practical needs in mind.

What Other Users Are Saying
Across the board, the sentiment from other users strongly aligns with our findings. The overwhelming majority praise the SKE SMART KEY ENERGY 10400mAh UPS for Router for its core function: it works exactly as advertised, providing seamless, uninterrupted power to network devices during an outage. One user summed it up perfectly: “Doing exactly the job, soon no power in the plug automatically kick in the ups. Good product.” Many, like us, were particularly impressed by its compact size, which allowed them to solve power backup problems in space-constrained areas like home theatre cabinets.
A recurring theme in positive feedback is the “set it and forget it” nature of the device. Users who work from home frequently call it an “invaluable backup,” with one stating they never even considered the need for one until a long power cut highlighted the massive impact of losing Wi-Fi. The versatility of its multiple outputs is another commonly cited advantage.
On the critical side, the feedback is minor but consistent. The most common complaint is the short length of the included mains power cord, which can restrict placement. A handful of users found the English instructions to be a bit simplistic or unclear, although the device’s operation is largely intuitive. We also saw one isolated report of a user receiving the wrong set of cables in the box, which appears to be a rare packing error rather than a widespread issue. This user feedback confirms that while not perfect, the device excels at its primary mission, providing a reliable and compact solution to a very common problem.
How Does the SKE Mini UPS Compare to the Alternatives?
It’s important to understand that the SKE SMART KEY ENERGY 10400mAh UPS for Router occupies a very specific niche. It is a specialist DC power backup. The most common alternatives are traditional AC UPS systems, which are designed for a completely different purpose. They take battery power, convert it to AC, and then your device’s power adapter converts it back to DC—an inefficient process for a router. Let’s look at how it stacks up against some popular AC models.
1. APC Back UPS PRO 1600VA UPS
- The APC Back-UPS PRO Series offers guaranteed battery backup and surge protection for high performance computer systems, networks, external storage devices, game consoles and other electronics.
