SKE SMART KEY ENERGY SKE 425VA/240W UPS Battery Backu Surge Protector for Computer UPS Battery Backup Uninterruptible Power Supply…, VL425

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.

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!

I bought this UPS to keep my home TV and router powered during outages, and overall, it's been solid. 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.

It worked fine for just over 2 months. Then it started switching back and forth from the power of the battery and the plug, till the battery was dead. Then whatever was plugged in would turn on and off every couple of seconds. And my time to return is well past the 30 days.

The UPS is fine, it took a little bit to setup, but everything is working fine. The only reason I gave it four stars is because it has only one UPS plug out of six plugs. Two plugs are setup for surge protection, the other three are just plugs. It does have USB charging ports, two USBA, and one USBC. If you need a low power UPS with only one UPS outlet I would recommend.

Purchased this unit just to back up computer tower and monitor, during short term power outage. Seems to keep power up for a good period of time. If power is out to long, gives you enought time to shut equipment down proerly so there are no problems.

This little UPS is exactly what I needed! The compact size makes it perfect for tight spaces. One of the biggest selling points for me was that the battery is replaceable, which extends the life of the unit and makes it more cost-effective in the long run. Set your expectations accordingly since it’s a 425VA UPS, so I doubt it would keep a desktop computer running for long. But for my needs — it keeps my Wi-Fi router and modem powered during outages and it works great. I’ve already used it during a power outage and had uninterrupted internet the whole time. A couple of things to note: - Only 5 of the 7 outlets have battery backup; the other 2 are surge protection only. - The replacement battery (RT1250B — not the A version) is a bit tricky to find and is pricer than one would think but it’s still cheaper than buying a whole new unit. If you need a small, reliable UPS for lightweight electronics like WiFi router or modem or security cameras, I highly recommend this one.

Works as expected
