Unlike traditional, bulky AC UPS units designed for desktop computers, these compact devices provide direct DC power, eliminating inefficient energy conversion and offering longer runtimes for the electronics they’re built to protect. The primary benefit is absolute peace of mind, knowing your network won’t crash during a power surge, flicker, or extended outage, keeping your smart home smart, your work-from-home setup productive, and your entertainment uninterrupted.
The ideal customer for this type of product is someone who relies on constant connectivity. This includes remote workers, online students, smart home enthusiasts with a web of connected devices, and serious online gamers. It’s for anyone who understands that the internet is no longer a luxury but a utility. Conversely, it might not be the right fit for those needing to power high-wattage AC devices like a gaming PC, a large monitor, or a NAS server. For those scenarios, a traditional, larger AC UPS from brands like APC would be a more suitable choice. The SKE SMART KEY ENERGY Mini UPS for Router 30000mAh is a specialist, excelling in its niche of safeguarding network hardware.
Before investing, consider these crucial points in detail:
- Dimensions & Space: This device is designed to be seen, not hidden away. With its sleek, mini-tower design measuring 12.95 x 8.64 x 21.08 cm, it’s meant to sit on a desk or shelf next to your router. Ensure you have the space for it and that its modern aesthetic fits your environment. It’s far more compact than a traditional UPS, but not so small that it’s completely invisible.
- Capacity & Performance: The headline feature is a 30,000mAh capacity, but the underlying technology is more important. It uses a LiFePO4 (Lithium Iron Phosphate) battery, which offers over 2,000 charge cycles—a massive improvement in longevity over standard lithium-ion. Pay close attention to the output ports (9V/12V DC, 24V POE, USB) to ensure they match your devices’ voltage requirements.
- Materials & Durability: The external casing is a sturdy plastic, but the real durability comes from the internal components. The LiFePO4 battery chemistry is not only longer-lasting but also safer and more stable than other lithium variants. The unit also includes multiple intelligent protections against short circuits, overcharging, and temperature fluctuations, safeguarding both the UPS and your connected devices.
- Ease of Use & Maintenance: Out of the box, it’s seemingly plug-and-play. However, there is a critical maintenance step for long-term health: the manufacturer recommends a full discharge-recharge cycle upon first use to calibrate the battery. As we discovered in our testing, and as many users have confirmed, skipping this step can lead to inaccurate battery readings and charging issues.
Understanding these factors will help you determine if this specialized mini UPS is the right guardian for your digital lifeline.

Unboxing the SKE Sirius: A Compact Tower of Power with a Few Quirks
The SKE SMART KEY ENERGY Mini UPS for Router 30000mAh arrives in a simple, unassuming white box. Inside, the unit is securely packed alongside a UK power cable and two DC output cables—one of which is a splitter, allowing you to power two devices from a single port. The instruction manual is quite sparse, which is a notable oversight given the importance of the initial battery calibration. Our first impression of the device itself was highly positive. It has a modern, mini-tower aesthetic reminiscent of a compact PC, finished in a tasteful matte grey. It feels dense and well-constructed, weighing in at a substantial 1.59 kg, which speaks to the large battery cells within. The standout feature is undoubtedly the bright, clear “Smart Display” on the front.

Putting the SKE Sirius to the Test: Real-World Performance and Hidden Flaws
A product’s spec sheet only tells half the story. To truly understand the SKE SMART KEY ENERGY Mini UPS for Router 30000mAh, we integrated it into our daily workflow, simulating power cuts and pushing its various outputs to their limits. Over several weeks of testing, it revealed itself to be a device of compelling dualities: incredibly powerful yet demanding, brilliantly designed yet audibly flawed. It’s a device that excels in its primary mission but requires a bit of understanding from its owner to unlock its full potential.
The LiFePO4 Heart: Capacity, Longevity, and a Critical First Step
The core of this UPS is its 30,000mAh LiFePO4 battery. This isn’t just a marketing point; it’s a fundamental advantage. LiFePO4 batteries are the gold standard for longevity and safety, capable of enduring over 2,000 full charge cycles before significant degradation. This means the SKE Sirius should theoretically outlast several generations of the routers it’s designed to protect. However, the 30,000mAh figure deserves scrutiny. As some technical users have noted, the *deliverable* capacity after accounting for voltage conversion and internal processes is lower. In our own tests, powering a consistent 14W load (a typical fibre modem and high-performance router combo), we achieved just over 6 hours of runtime from a full charge. This is an excellent result that will cover 99% of power outages, but it aligns with a more realistic usable capacity in the 6,000-7,000mAh range at the output voltage. The marketing is ambitious, but the real-world performance is still very strong.
More importantly, we must address the battery calibration. We initially ignored the advice and plugged it straight in. After a few days, the battery display was stuck at 84% and wouldn’t charge further. This reflects the experience of numerous users who reported similar issues. The fix was to follow the recommended procedure: we connected our router and modem and let the UPS run until it was completely drained and the display shut off. Only then did we plug it back into the wall. After this “deep cycle,” it charged flawlessly to 100% and has provided accurate readings since. This is a non-negotiable first step. It’s a frustrating quirk for a premium device, but once performed, it unlocks the stable, reliable performance that makes this mini UPS a feature that really sets it apart from simpler models.
A Hub of Connectivity: Powering More Than Just Your Router
Where the SKE Sirius truly shines is its incredible versatility. This is not just a router backup; it’s a multi-device power hub. The rear panel is packed with outputs: dedicated 9V and 12V DC ports for network gear, a 24V POE (Power over Ethernet) port for compatible security cameras or access points, and even a DC input that can be used with a small solar panel for off-grid applications. This array of DC outputs ensures clean, efficient power delivery to your most critical devices. We successfully powered a 12V Fritz!Box router and a separate 9V modem simultaneously through a simulated 5-hour outage without a single hiccup.
What elevates it from a utility to a truly multi-purpose gadget are the front-facing ports. With both USB-A and a 45W USB-C port, it transforms into a formidable power bank. During our testing, it became the go-to charger on the desk. The Type-C port fast-charged our MacBook Air and our smartphones with impressive speed. This dual identity is its killer feature. When plugged in, it’s a silent guardian for your internet connection. When you need portable power, you can grab it and go, with enough juice to charge a phone multiple times over or keep a laptop running through a long meeting. This hybrid functionality justifies its price tag and makes it an exceptionally useful piece of technology to have in any modern home or office. Check the latest price and availability to see if it fits your budget.
The User Experience: Living with the Smart Display and the Fan
Interacting with the SKE SMART KEY ENERGY Mini UPS for Router 30000mAh is a pleasure, thanks largely to its excellent display. It’s bright, clear, and provides genuinely useful information at a glance. You can see the exact battery percentage, icons indicating whether it’s running on AC or battery power, and most impressively, the real-time power draw in watts of your connected devices. This is invaluable for understanding your equipment’s energy consumption and estimating remaining runtime. It’s a pro-level feature that instills confidence and takes the guesswork out of battery backup.
However, there is an audible trade-off for all this power. When the device is charging—which is most of the time when used as a UPS—an internal cooling fan activates. In a quiet room, this fan is not just audible; it’s noticeable. Several users described it as a “whine” or “whistle,” and we found this to be accurate. It’s a high-pitched sound that can become distracting in a home office or bedroom environment. The fan does its job, as the unit never felt more than slightly warm to the touch, but its acoustic profile is a significant drawback. Whether this is a dealbreaker depends entirely on your sensitivity to noise and where you plan to place the unit. It’s a flaw in an otherwise stellar design and something we hope to see improved in future revisions.
What Other Users Are Saying
Across the board, user feedback confirms our own findings, highlighting a product that is both loved for its capability and criticized for its quirks. On the positive side, many users celebrate it as a “super handy large portable power bank” that happens to also be a great UPS. One user reported powering a Fritz!Box router, an internet module, an NVR, and a monitor for over five hours, calling its performance “great.” Another confirmed our test results, noting their two routers with a 14W total draw lasted a solid six hours on half a battery.
However, the negative feedback is just as consistent and focuses on two key areas. The most prevalent issue is the battery calibration. One user stated, “I never drained the battery when using it for the first time and several weeks later the battery level was stuck at 80%.” They, like us, fixed it by performing a full drain. Others were not so lucky, with one user’s unit eventually failing to hold a charge at all, becoming an “expensive extension cord.” The second major complaint is the fan noise. A user summed it up perfectly: “The fan during recharging is really noisy… it makes a really annoying whistle,” making it unsuitable for quiet spaces like an office or bedroom. These shared experiences underscore the importance of being aware of the initial setup process and the device’s acoustic footprint before making a purchase.
