SKE Compact Size 425VA/240W UPS Battery Backup & Surge Protector for Computer UPS Uninterruptible Power Supply UPS Phoenix VL425

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.

Gave it a full charge out of the box before installing, but no power outages in the week since getting it...so we tripped the breaker to test it, worked as advertised. The goal for having it is to keep the HO computer working through glitches and short outages, buying time to save work in progress and shut down safely. This UPS appears to accomplish the task, and at a flash sale price that made it a very affordable choice.If it does not live up to expectations, I'll post an update.

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.

I was excited about this product because it was similar in price to the basic APC backup, but included surge protection for my ethernet. Well, I went through 2 rounds of returns and never got one that worked. So there's your explanation for the reasonable price, i guess.I got this UPC and the battery wouldn't hold a charge. So I returned it for a replacement unit, and that one's battery wouldn't charge either. At that point, I'm out. I'll buy the APC brand—I know there's a much higher chance that those will arrive in working order.I suspect the issue is that these units come with the battery already connected. Other UPC's I've owned don't do that, to avoid batteries losing too much charge in the warehouse. Because once a lithium battery gets below a certain charge, you can't recharge it—at least not easily. Ridiculous, easily avoidable production flaw.

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!

The item looks well designed and made. Installed a few days ago and have not experienced a blackout yet.When first installed after charging the battery for several days, there was no power on the battery backup outlets. I sent an email to the manufacturer and they informed me that one must hold the power button for 3 seconds to turn the unit on. Once the power is on and the green LED is visible, there was power to all outlets. The instructions have no mention of the 3 seconds, so I recommended they update the instructions. Regarding the battery, it is very easy to replace but beware that the size is not very common, in particular the width. Most available batteries recommended for replacement are 2.5 inches wide, which will not fit in the 2-inch cavity of the UPS. After much searching with the help from other reviewers I was able to find it.
