Review: Nice little unit for keeping low power electronics running! - I bought this smaller UPS to keep my Fiber ONT running when there's an outage or a power blip (the rest of my network - APs, Switch, Gateway etc) is already on a rack-mounted UPS so this ONT was my 'single point of failure' when we lose power for a while. It's a well made, smaller UPS. It's quite basic, with a power button for turning it on and off, some simple LED indicators to show power or battery mode, and an alarm for when the power is out. It wasn't super obvious to me that the battery-protected ports were the black 'normal' looking plug sockets and not the white ones. At first I had the ONT plugged into the wrong sockets and wasn't sure why it didn't work. (The white ones are surge only, no battery backup) It's powered by a single 5Ah battery. It transitions to battery mode on the loss of power instantly, there's not interruption at all for the device(s) being powered, and I figure based on some rough math that it might keep my low power ONT running for 45 minutes or so. I will test that completely at some point. The instructions state that you have to fully charge the battery before first use, so I left it plugged in overnight before I used it. I'm impressed. It's a low cost, basic UPS that should work perfectly for a use case like this. Given the small battery I wouldn't think it will keep much running for very long, and it's rated for lower than most desktop PCs will consume when they're working hard... So modems, routers, ONT units, maybe a switch or two... but don't expect to protect much more than that. Once I've tested how long this keeps my ONT running for I'll update my review. I also might try to find a 12V 7Ah battery that fits this unit... again, based on my calculations that would increase the time it'll keep devices on by about 40%... but I intend to experiment and find out! Impressive little unit! Perfect for something like this! Review: Bought just for my cable and modem setup in laundry room - This 240 backup battery surge protector has given me real peace of mind. The surge protection is solid, and the built-in battery backup kicks in instantly during outages, keeping my PC and streaming equipment safe without even a hiccup. It’s powerful enough to run multiple devices at once, and I’ve already seen it save my setup during a short power flicker. The design is sturdy and well-built, with plenty of outlets and clear indicators so I know exactly what’s going on at a glance. Setup was simple, and it runs quietly in the background without being intrusive. For anyone who relies on their electronics — whether for work, gaming, or streaming — this is an essential piece of gear. Reliable, tough, and worth every penny for the protection it provides. ## Features - 7 Standard US Outlets: 5 black outlets for backup & surge protector, 2 white outlets for surge protection only. Backup your computer, router, modem, and other network devices. - Additional Ports: RJ45 port for surge protection, 2 USB outlets, and 1 Type-C outlet for fast charging your phone, laptop, and more. - Automatic Voltage Regulation: Simulated sine wave current provides stable and clean power, protecting your network systems from surges and extending the lifespan of your devices. - Unique Design: Compact size fits any space and can be placed vertically or horizontally. - Replaceable Battery: User-friendly design allows for easy battery replacement with just a Phillips screwdriver. - Quiet Operation: A simple press of the power button silences the unit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CZ7D8YHW | | Battery Cell Composition | Sealed Lead Acid | | Battery Cell Type | Sealed Lead Acid | | Best Sellers Rank | #21 in Computer Uninterruptible Power Supply Units | | Brand | SKE SMART KEY ENERGY | | Color | Black | | Connector Type | USB, Type-C | | Customer Reviews | 4.2 out of 5 stars 400 Reviews | | Enclosure Material | Plastic | | Form Factor | Tower | | Frequency Range | 50-60 Hz | | Item Dimensions | 11.7 x 3 x 6.7 inches | | Item Dimensions D x W x H | 11.7"D x 3"W x 6.7"H | | Item Weight | 8 Pounds | | Manufacturer | SKE SMART KEY ENERGY | | Material | Plastic | | Maximum Power | 240 Watts | | Model Number | VL425 | | Number of Outlets | 7 | | Output Voltage | 12 Volts | | Output Wattage | 240 Watts | | Power Plug Type | Type B - 3 pin (North American) | | Product Dimensions | 11.7"D x 3"W x 6.7"H | | Upper Temperature Rating | 120 Degrees Fahrenheit | | Voltage | 12 Volts | | Warranty Description | 1 year for battery, 2 years for machine | | Wattage | 240 watts | ## Product Details - **Battery Cell Composition:** Sealed Lead Acid - **Brand:** SKE SMART KEY ENERGY - **Color:** Black - **Product Dimensions:** 11.7"D x 3"W x 6.7"H - **Voltage:** 12 Volts ## Images ![SKE SMART KEY ENERGY SKE 425VA/240W UPS Battery Backu Surge Protector for Computer UPS Battery Backup Uninterruptible Power Supply…, VL425 - Image 1](https://m.media-amazon.com/images/I/61g4FGaDl9L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice little unit for keeping low power electronics running! *by D***E on January 11, 2025* I bought this smaller UPS to keep my Fiber ONT running when there's an outage or a power blip (the rest of my network - APs, Switch, Gateway etc) is already on a rack-mounted UPS so this ONT was my 'single point of failure' when we lose power for a while.

It keeps my fiber modem running for over two hours, which is clutch when the power cuts out. The design is sleek and doesn’t take up much space—definitely a plus. For the price, it's a decent value. That said, the battery life and quality are hit-or-miss. Some users (me included) say it holds power well, but others have had it die even after a full 12-hour charge. Build quality seems decent, but again, some folks got lemons and reported defects out of the box. The instructions are barebones—if you're not tech-savvy, you might scratch your head a bit. Also, be aware the fan can get noisy when it's running on battery power. Not a dealbreaker, but something to note if you're using it in a quiet room. ## Frequently Bought Together - SKE Compact Size 425VA/240W UPS Battery Backup & Surge Protector for Computer UPS Uninterruptible Power Supply UPS Phoenix VL425 - APC UPS Battery Backup and Surge Protector, 600VA/330 Watts Backup Battery Power Supply, BE600M1 Back-UPS with USB Charger Port - CyberPower ST425 Standby UPS System, 425VA/260W, 8 Outlets, Compact, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/636561624-ske-smart-key-energy-ske-425va-240w-ups-battery-backu](https://www.desertcart.hr/products/636561624-ske-smart-key-energy-ske-425va-240w-ups-battery-backu) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-22*
