It's surprising to find a sinewave UPS from APC that's not from the Smart UPS line. For the first time, "sinewave" makes its way to the Back UPS lineup and is finally made affordable to the masses. Is it earth shattering news? No. Cyberpower has been offering cheap sinewave UPSes (CPxPFCLCD) for years. However, it's certainly great news for consumers who will now not only have a viable alternative, but one that is backed by legendary reliability and support.Why sinewave? AC power coming out of your outlets look like sinewaves, a smooth periodic oscillation. Typically on any UPSes that are not on battery mode, the output from the UPS also look like sinewaves. It's when the power cuts out and the UPS battery kicks in where things get interesting. On non-sine wave models, the power output would actually look like very rough boxy steps / step square waves. The fancy marketing term is a step approximated sinewave. On sinewave models, the power output when the UPS is on battery actually look identical to when they are coming out of your outlet: a pure sinewave. Traditionally, the argument is that sinewave UPSes are $$$$, and most modern electronics can handle step approximated sinewave and thus, the consumer can save some money and get the cheaper UPS. However, when a sinewave UPS is priced so close to a non-sinewave model, the point is moot.The packaging is the usual APC affair: exceptional. A well protected UPS, user manual, data cable, and coaxial cable is what you'll find inside the box. Like all APC units, this unit comes with a Quality Assurance Test slip that tells you how awesome your new shiny UPS is and even tells you its manufactured date, so that you can plan for that inevitable battery replacement 3-5 years down the line. As usual, the unit arrives with its batteries disconnected to avoid unnecessary drain during storage/shipping. Fortunately, it also comes with a big yellow stick with easy to follow instructions to get the batteries connected in no time. Newbies rejoice!Having owned two Cyberpower CP1500PFCLCD Sinewave UPSes, the similarities are apparent (so similar, you'd think they were made in the same place):- They both have nearly identical dimensions- They have (extremely) similar LCD displays and interfaces- The number of outlets at the back are identical- Both are practically silent.That said, the APC has a few things that make it stand apart:- Build quality is a bit higher on the APC, and battery compartment access is easier.- APC has bigger vents at the top which may attribute to better cooling.- It has one more UPS battery backup outlet and one less surge only outlet (6/4 versus an even 5/5 on the Cyberpower) As the primary purpose of a UPS is to have battery backup power, having more battery backup outlets is better.- There is a modern USB-C port and a USB-A port capable of a combined 5V 3A output, while the Cyberpower only comes with 2x USB A ports for a combined output of 5V 1A. The APC should allow you to charge even the hungriest of mobile devices.- Gigabit Ethernet surge protected ports. (Whoa!)- 2x 12V 9Ah batteries!I want to emphasize on the last point and how it relates to runtimes. I was completely taken aback when I saw the inclusion of 2x CSB HR1234W 12V 9Ah batteries (great brand btw). These are practically the same as the ones included in my 1500VA Cyberpower CP1500PFCLCD UPS, also 2x 12V 9Ah. Obviously, runtimes cannot compare with heftier business grade UPSes such as APC Smart-UPSes that uses much bigger batteries (2x 12V 18Ah) in 1500VA models. However if I am to suspect, the runtimes of the 1350VA model will easily match the Cyberpower 1500VA model, which makes it an exceptional value. Furthermore, in comparison to its bigger brother the APC BR1500MS 1500VA model, I find the difference between that and this lower 1350VA model is the inclusion of better CSB UPS12580 batteries, which ironically are also 2x 12V 9Ah but with supposedly higher capacity (96w/cell versus 36w/cell). I'm not completely sure that different batteries justifies the higher price tag. Mind also that when time comes to replace the 12V 9Ah batteries, the 36w/cell variant is likely the easier one to source and thus voiding advantages of going with the nicer batteries in the BR1500MS.Not much negatives can be said about the unit. It is practically flawless as expected of APC. The only thing I can comment is that fact that this unit uses a proprietary USB data cable (USB to RJ45) versus the more usual “printer” USB A to USB B cable. It is definitely not as easily replaceable, so don’t lose it!I settled on the 1350VA model because I was too cheap to get the 1500VA model for a measily extra 150VA. I was not disappointed. The fact that the supplied batteries equal that of a 1500VA model is astonishing. From a battery perspective alone, the runtimes on the BR1350MS should easily match that of a CP1500PFCLCD, regardless of what the literature says. Touches like high output USB charging ports, gigabit Ethernet surge protection, and an extra battery backup outlet really puts it best of the rest in its price bracket for 2018. 5/5
