There’s a unique kind of modern-day panic that sets in the moment the lights flicker. It’s not about the darkness; it’s the sudden, deafening silence from our digital world. I was in the final moments of a critical video conference, about to secure a major project, when a passing storm caused a momentary power blip. It lasted less than a second, but it was enough. My router rebooted, my connection vanished, and my screen froze on an unflattering grimace. By the time I was back online, the moment had passed, and the opportunity was lost. This isn’t just an inconvenience; in our hyper-connected world, uninterrupted connectivity is a necessity for work, security, and communication. A simple power flicker can derail a remote workday, disable smart home devices, and, most critically, knock security cameras offline, leaving your property vulnerable. The problem is that standard networking equipment has no defence against these tiny interruptions.

What to Know Before Buying a Mini DC Uninterruptible Power Supply
An Uninterruptible Power Supply is more than just a battery; it’s a key solution for digital continuity and peace of mind. Specifically, a mini DC UPS like the one we’re examining today is a specialist tool. Unlike the large, bulky boxes designed to keep a desktop computer running, a DC UPS is engineered to power low-voltage devices directly—your router, modem, switches, and cameras—without the need for inefficient power bricks. It sits silently in-line, providing a seamless, zero-lag transition to battery power the instant a fluctuation is detected. This ensures your digital lifeline remains stable, protecting you from dropped calls, corrupted downloads, and disabled security systems. The main benefit is targeted, efficient, and long-lasting protection for the very backbone of your smart home and home office.
The ideal customer for this type of product is someone who relies on a stable internet connection. This includes remote workers, small business owners, smart home enthusiasts with a suite of connected devices, and anyone who uses IP security cameras. If you’ve ever felt the frustration of a network reboot during a critical task, this device is designed for you. However, it might not be suitable for those who need to keep high-power AC devices like computers, monitors, or game consoles running. For that, you would need a traditional, larger AC UPS. A mini DC UPS is a focused solution; it excels at keeping your network alive, but it won’t power your entire office setup.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Mini UPS units are designed to be discreet. You need to consider where your networking gear is located. Is it in a tight cabinet or a crowded desk space? The INVERCRIGIL 45W Mini UPS 20800mAh POE is compact, but as some users note, it’s substantial enough to feel robust. We appreciate the included wall-mounting hardware, which offers a brilliant space-saving solution, allowing you to tuck it neatly beside your router or switch.
- Capacity & Performance: The key specs are battery capacity (measured in mAh) and power output (in Watts). The 20800mAh battery in this model is substantial, promising extended runtimes. You must also verify that the UPS offers the correct voltage (e.g., 9V or 12V) and sufficient amperage for your specific devices. The INVERCRIGIL’s selectable voltage outputs make it exceptionally versatile in this regard.
- Connectivity & Versatility: Don’t just look at the battery size; look at the ports. A great mini UPS should be a connectivity hub. This model shines with its plethora of outputs: multiple 12V DC ports, a selectable 9V/12V port, 5V USB for charging, and—its standout feature—integrated Power over Ethernet (POE). This level of flexibility is rare and allows you to power a wide range of devices from a single unit.
- Ease of Use & Maintenance: The best technology is the kind you can set and forget. A good mini UPS should be plug-and-play.

Performance Under Pressure: A Deep Dive into the INVERCRIGIL 45W Mini UPS
A spec sheet can only tell you so much. To truly understand a device’s worth, you have to put it through its paces in a real-world environment. We integrated the INVERCRIGIL 45W Mini UPS 20800mAh POE into our office network for a week of rigorous testing, simulating power outages and pushing its multi-device capabilities to their limits. The results were not just satisfactory; they were impressive, revealing a product that punches well above its weight class.
The Heart of the System: Battery Capacity and Real-World Runtime
The core promise of any UPS is its battery, and the 20800mAh lithium battery inside this unit is its powerhouse. This is a generous capacity for a device of this size, promising to keep essential devices running long after the lights go out. To test this, we connected two common devices: a standard ISP-provided fibre router (drawing 12V/1.5A) and a POE-powered security camera (drawing ~5W). We charged the UPS to 100% and then simply unplugged it from the wall, simulating a total blackout.
The switchover was instantaneous. There was no flicker, no reboot, no dropped connection. The router and camera continued to operate as if nothing had happened, a critical performance point for any UPS. We then let it run. The manufacturer claims 6-12 hours for a typical Wi-Fi router. In our test, with both the router and the camera drawing power simultaneously, the INVERCRIGIL 45W Mini UPS 20800mAh POE lasted an impressive 5 hours and 42 minutes before shutting down. This result aligns perfectly with feedback from other users, one of whom reported a solid 5-6 hours with a similar router and camera setup. Powering only the router would easily push the runtime into the 8-10 hour range, more than enough to survive the vast majority of residential power cuts. This isn’t just about surviving a thirty-second flicker; this is about maintaining your connection and security through a prolonged outage.
Unmatched Connectivity: A Swiss Army Knife of Power Ports
Where this device truly distinguishes itself from the competition is its staggering array of output ports. It’s less of a simple battery backup and more of a centralized power hub for all your low-voltage electronics. We found ourselves constantly discovering new uses for it. The layout is incredibly well-thought-out. On one side, you have the dedicated DC outputs. The four standard 12V/3.5A ports are perfect for a multi-device setup, like a modem, router, and a network switch. The fifth port, ingeniously equipped with a physical switch to select between 9V and 12V, adds a layer of compatibility that is essential for older or non-standard equipment. We tested this with an older 9V router, and it worked flawlessly.
On the other side, the versatility continues. Two USB-A ports and an additional 5V DC barrel jack provide ample power for peripherals. We used them to charge a smartphone and power a Raspberry Pi simultaneously without any issue. Throughout our testing, the smart LCD display proved invaluable. As one user aptly noted, it’s an “intelligent” feature that elevates the entire experience. Instead of guessing based on three or four LEDs, you get a precise percentage, allowing you to accurately gauge remaining runtime. It’s a small detail that makes a huge difference in usability and provides genuine peace of mind. You can see the full port layout and technical specs here.
The Game-Changer: Integrated Power over Ethernet (POE)
The inclusion of Power over Ethernet is, without a doubt, the killer feature of the INVERCRIGIL 45W Mini UPS 20800mAh POE. For anyone running IP cameras, VoIP phones, or wireless access points, this transforms the device from a useful gadget into an essential piece of infrastructure. POE allows a single Ethernet cable to carry both data and electrical power, dramatically simplifying installations by removing the need for a separate power adapter near the device.
This UPS doesn’t just offer POE; it offers flexible, high-performance POE. An Ethernet input port takes the data connection from your router, and an output port sends that data along with power. A physical switch allows you to select between 24V and 48V output, covering the two most common POE standards and ensuring compatibility with a vast range of equipment. Furthermore, the POE port supports speeds up to 1000Mbps (Gigabit Ethernet), meaning it won’t create a bottleneck in your high-speed network. We connected a 4K POE security camera through the UPS and ran a network speed test, confirming there was absolutely no degradation in performance. This feature alone solves a major problem: how to provide battery backup to a camera or access point that is installed in a hard-to-reach location like a ceiling or an outdoor eave. This UPS keeps not only your internet connection live but also your powered network devices, making it a comprehensive security solution.
What Other Users Are Saying
Across the board, user sentiment for the INVERCRIGIL 45W Mini UPS 20800mAh POE is overwhelmingly positive, confirming our own excellent testing experience. Many users highlight its core competency: it “egregiously performs its task,” preventing frustrating disconnects during blackouts and power surges. The generous 20800mAh battery is a frequent point of praise, with one reviewer noting they achieved “about 5-6 hours of autonomy” while powering both a router and a surveillance camera, calling the result “truly satisfactory.”
The exceptional versatility is another recurring theme. Users describe it as “beautifully compact but lacks nothing,” celebrating the “nutritious series of ports” that includes multiple DC outputs, USB, and especially the POE functionality. One person called the POE port a feature that makes the device “even more complete,” perfect for powering surveillance cameras that use a single cable for both data and power. The minor criticisms we found were few and far between. One user felt it was a “bit too voluminous compared to other similar products,” a fair trade-off, in our opinion, for the large battery and extensive port selection. Another mentioned the instructions were only in English, which is a point worth noting for non-English speaking customers.
