APC Back-UPS Pro 1350VA UPS Battery Backup & Surge Protector, BX1350M Backup Battery Power Supply

First, let me rate the product. I have three of these UPS units in my house now. This series of UPS delivers output power that has a much better approximation to a true sine wave compared to many UPS units without having to spend $400. As a result, the newer PC power supplies are much happier and thus quieter and there is money left in my wallet. The battery is easy to install and change, the display is informative, and you have the option to turn off the visual display when the unit is running. The unit itself is also very quiet. There is an option to connect the UPS to a USB port on a Windows PC (don't know about Mac) with the included cable and Windows 7 or later will recognize the UPS. You can then program your PC to automatically shut down safely when the UPS is drained to a specified level. I haven't had to use that feature because we have occasional brownouts and very brief outages, but very rarely long-term power outages. In short, great product. I have three and will buy more as I need them.Second, let me rate Amazon's shipping department. Simply stated they did a poor job. The last UPS I received was in a box with very little packing material. When I took the UPS out of the box, the case was broken well beyond repair and there were bits of plastic in box that had broken off. I didn't dare even to test the thing. Surely UPS must have been too rough in handling, but there wasn't any real packing material either. The UPS didn't stand a chance. I contacted Amazon and their customer service folks got me fixed up with a replacement, but it was a hassle I wish I could have avoided. The replacement arrived OK along with more packing. How lucky do you think you are?I really like the UPS and wish I could buy it retail. I have my doubts about buying heavy and fragile items from Amazon.

Nice as usual with APC brand - however would love to see the outlet plug ins on a white panel - cannot see the prong holes! Well ventilated and handles our wonky power outages very well. We also have these for computers and peripherals. Been buying APC for over 20 years - Glad they are still alive!

I've used this ups for around 2 1/2 - 3 years and once I moved cross state I had to leave it behind due to the weight of it and being not as cost effective to ship across the us and ended up purchasing another one since it worked amazingly compared to the other ups's I've tried, gives you a buffer period between power flickers to not have your desktop pc completely shut off or a 5-15 minute window depending on your pc specs to power everything off safely in a full outage, I have a fairly beefy power hungry pc with a rtx 3080 and other high end parts and this is one of the few I've seen that can handle the wattage usage of my pc at this price point while still managing to keep my pc on during power flickers, also nice it has a side that's purely for surge protection and Ethernet surge protection, It's super important to have a solid Ethernet surge protector on your modem, had my previous 300$ 5 gigabit modem die to lightning hitting a tree in our front yard and having lightning travel up the copper coax line and frying it so make sure you're getting usage out of all of the features of this ups and save yourself money down the line with dead/fried components!

I've owned this UPS for about a month so far. It reports two power events so far. One being a blackout for about 4 seconds and the other was a voltage surge. The voltage surge permanently damaged a TV which my roommate foolishly put on a power-tap instead of a surge protector and my HTPC probably would have suffered the same fate were it not for this UPS.I have my HTPC, modem and router which use ~50 watts when idle. The UPS reports ~45 minutes of battery power for this configuration.Pros:- It works, saved my electronics during a surge and kept them running during a blackout.- Respectable VA and wattage ratting. (~45min run-time @50 watts)- No fan! Quiet (sort of, see notes)!- The LCD is a nice feature to easily look at the status of the UPS.- Good looking.- APC powerchute is simple to use and seems adequate for non-industrial users.Notes:- Some other reviews are reporting a humming noise which I suspect is just transformer hum. There is a slight transformer hum in my unit, that can barely be heard when I'm less than 1 meter from the UPS. When I'm sitting on the couch (~2 meters from UPS) I can't hear it no matter how much I try to listen for it. However, my UPS is reporting a building wiring fault, which I suspect is the root cause of the problem and not something inherently wrong with the UPS itself. If you hear a hum, check the building wiring fault light, or if you know how to check for DC noise or ground loop faults in your wiring do so before blaming the unit as being faulty.- Not really APC's fault but APCUPSD (3rd part interface) doesn't have working USB drivers for windows 7, so it wont work with this device.
