I live in a remote, rural area right beside the Atlantic ocean. Needless to say, we have lots of electricity issues and outages in my region. It’s one thing to plan ahead for storms and make sure that things are unplugged or turned off when you have advanced notice, but unfortunately, it's the unexpected surges and brown outs that damage computers. Since getting this UPS, I never, ever worry about these issues because my APC UPS catches every single one of them with ease. With an average runtime of 20 to 30 minutes to save any open files and gracefully power the system off, I’ve no cause for undue concern anymore.Ya gotta luv the fact that you don’t need to junk the whole unit when the battery starts giving out - you just replace the battery. APC has been the go-to, most-relied-upon UPS manufacturer since many decades now; and for good reason! Housing a field replaceable battery and consistently delivering solid reliability makes this unit a very sensible choice. I highly recommend it!

J'ai acheté ce UPC pour une seule chose: alimenter mon routeur et le modem-cable pendant les pannes de courant. J'ai fait exprès pour prendre le modèle avec plus de capacité pour ne pas avoir à faire de compromis sur l'autonomie. J'avais connecté 2 autres choses dessus lors de l'essai: une base de recharge pour un téléphone sans-fil et une base de recharge pour un téléphone cellulaire (qui n'était pas en fonction). Je ne croyais pas que cela ferait une différence matérielle. À la première panne de courant, j'ai pu avoir environ 2h15 d'autonomie avant que le UPC commence à émettre des sons d'avertissement. Je m'attendais à beaucoup plus que ça. Il faudra que j'essaie avec seulement le modem et le routeur la prochaine fois, mais jusqu'à présent, c'est un gros "fail". Pour le prix, ça ne vaut pas le coup. J'ai beaucoup plus d'autonomie (plus de 12h) en branchant les deux appareils sur ma station d'alimentation CAT achetée pour moins cher chez Costco.

The 850VA has been great for me when working from home. We are in a developing area and incur frequent short power outages. We also just had a windstorm that took out power for 12 hours. This has been great to keep me working through the smaller outages (approx. 1-1.5 hours to run an iMac and WiFi) and for the longer outages it allows me to notify clients, wrap up work and shut down the computer safely (runs WiFi only for about 3 hours). If this ever dies I might upgrade to the higher capacity ones, but so far it's been a great product.

I haven’t really had an issue with it yet, but I also, haven’t lost power for a long time to really test it. It is a good quality UPS, though it is a bit heavy as it uses a lead acid battery for backup, it has decent battery life, averaging around 12 hours powering a low wattage lamp and a phone charger, the silence button is really nice, especially since it is a toggle switch, you won’t wake up to it beeping in the middle of the night.

Many years ago, a local power surge (the odd thunderbolt) blew out the CPU on an iMac even through a typical power surge protected multi-plug surge protected electrical cord extenders. At that time, I bought the predecessor APC device and went through one cycle of battery replacement. The batteries are lead-acid so they eventually decay. When the second battery died, it turned out that the original device had gone out of support. So...I bought the newer version. The cost was not too much of an increase over a battery alone, especially not when amortized over the lifetime. The new design is sleeker and, I presume that as another reviewer said, the electronics have at least a decade of improvement as well. I don't need the battery support much, but it is an important part of the surge protection. It has, once or twice, allowed me to shut down cleanly when we had a power outage – rare where I live.The outlets work well. Unfortunately, geometry limits how many power bricks will plug in cleanly. So I make sure that computers and external drives are on the surge/battery outlets and just run an extension plug block from a surge only outlet for any other things that do not require battery like desk lights.This has been a reliable solution to a common problem at a reasonable price. I do not remember why I chose APC in the first place, but I have no regrets. And no more blown CPUs!
