SL700U Standby UPS System, 700VA/370W, 8 Outlets, Slim Profile, Black

Note that I am only a week into the new install, so can not vouch for longevity as of yet. I purchased this item for my home office. The set up includes Router, WIFI, PC, and Wyze Security System Base power on the power + surge protected portion of the unit, and then have just one other item on Surge only portion. Highly recommend using the free CyberPower software to manage and observe the details of this back-up- its very good. Currently I am pulling only 75 watts total with an estimated back up time of 35 mins. when power goes down. I believe for the price and size it is well worth it, with the smaller footprint fitting neatly under my printer cart. Back in the old days a 700VA would require 4 to 5X the space as this unit to offer the same back up time- with not nearly as many features. Item of note here would be that I saw a lot of people ask how to turn the alarm beep off in a power outage, and didn't realize until they are suddenly in the dark having to try and figure it out. I looked it up, just 2 quick presses of the green power button will disable the alarm if/when that time comes. All in all I believe this item to be a quality, feature rich product for a SOHO environment. I read that there was some dismay regarding the Mfg warranty if the battery goes bad or in need of repair, so I spent the extra $ 8 for no questions asked warranty coverage. For essentially 10% of the total value its worth it for me to have worry-free service if ever needed for 36 months. Enjoy!

I asked the Amazon community a while ago about if anyone knew how big the internal circuit board was for the Cyberpower SL700U battery backup? No one could give me an answer and since this unit seemed to be the smallest, most compact design for a larger 700 watt backup supply on the market, I decided it would do for my purposes. I am writing this review not as an end use of the actual device, but to re-purpose the battery backup’s structure, it still functions as intended, just in a different package and I believe that customers may like to see how these units work as well as how they can be modified (yes, you will void the warranty) I make computer hard drive backups and restorations every 2 months, for myself and others I help with their operating systems, so I use an external data backup device: Startech SM2DUPE11. Previously I used an earlier model that could not do NVMe style drives but was still efficient and quick. When backing up data of any type, it is best to have a power supply that won’t fail on you else you may lose your destination drive or corrupt the source data if you have a blackout. The UPS is the answer. The duplicator needs a home, so a good solid case to carry and store it in makes sense. Last, the UPS, which I integrated into the case, adding in a couple of features and using components to replace the circuit board mounted power switch and power LED indicator light. I decided to add in a power receptacle in case I needed to plug something in while doing the backup off site. Designing the layout on an acrylic plastic board and then drilling, cutting and filing out slots and holes, modifying the two heat sinks on the Cyberpower SL700U’s circuit board and adding in a separate 12 volt DC power supply to power two small 40 mm fans to cool those two heat sinks I shortened, all of this needed careful planning on how to arrange everything. The Startech duplicator’s power supply adapter also needed a parking stall in the layout. So after removing it from it’s case, and trying a few positions with two slimmer 6 volt batteries to power the UPS during a power outage, I had my plan. The original Cyberpower battery was 2 inches thick, and obviously I could not use this effectively if trying to place it flat inside of the carry case I used, the Nanuk 910 case. I found a flatter, 1.3” thick, 6 volt battery to use, but I would need two of them instead of one. You can replace a 12 volt battery with two 6 volt ones if you connect them in series. This gave me the advantage of increasing the amp hour rating from the Cyberpower’s 5 amp hour 12 volt battery to 7 amp hours for the replacements. My project took a while to accumulate all the needed components, all ordered through Amazon, and once I had replaced the short battery cables on the circuit board with lengthened ones, and soldered on wires to connect the switch and LED light, I was ready to assemble. The photos show the SL700U disassembled then it’s circuit board being put together and mounted to the underside of the acrylic plastic board. I consulted with the Startech technical support to confirm that their duplicator being placed so close to the UPS power supply would not cause any issues in its operation and they confirmed that there should be no problem. The project is done and my SL700U powers my duplicator station, protecting this investment from power failures as well as surges during normal operation. I am pleased that I chose this particular device, the Cyberpower SL700U, as it was a great compact design that I could incorporate into my plan and provide power for the nominal 60 watt power usage of the duplicator. This should prove me with many years of service. Hope this helps you decide if the SL700U is for you.

I bought this to protect my game consoles and TV during power outages. In Michigan when we get bad storms, the power doesn't just politely go out: it flickers on and off with surges 10 or 12 times first, frying your electronics! After my XBox One was destroyed by that I stopped being cheap and got this for behind the TV. At 370w I don't think it'll run my TV and Series X on an actual load for very long, but it's enough to get things safely shut down and unplugged if you don't have a standby generator. This is also perfect if you do have a standby generator, providing stable power while the mains dies violently and then giving clean power while the generator is running. (If it's old like mine that comes with constant brownouts!) If you live in an area where you lose power in the winter or during spring storms get this, it's slim enough to hide behind your TV pretty easily and will protect your much more expensive TV and game consoles. I've only lost power once since buying this but it did its job, can't comment on battery longevity yet but if it lasts 3-5 years I'll be happy. I have another CyberPower UPS I bought in early 2021 still going strong so I'm happy with the brand so far.

Works great. And amazing customer service.

Easy to set up and priced good enough to just buy a new one when the battery goes out. Been reliable so far to keep my router and switch up when we had power issues.
