If you use a USP to work during a power outage for 1-2 hours (no less), what is the result?

[LovingLoverReturned]

I KNOW USPs aren't supposed to be used that way, this is just a question. So please answer the question if you qualify.

[Moose304]

I use a UPS for two reasons. First off my UPS will not supply current for much longer than roughly 45 minutes. I have ALL my electronics hooked up into one. EVEN my TV! The one in my office handles my PC, my two monitors, and both my printers as well as my modem and router. The reason I do this is the other reason I use a UPS. Every time an AC or a Refrigerator compressor starts off it sends garbage into the electrical lines that on the microscopic level hammer the devices. A UPS filters all that crap out. If I lose my power my UPS allows me to start the shutdown process as I save my work.

It won't be a problem provided the UPS is rated to handle the power load for that length of time. Just keep an eye on the time remaining. If it's a larger device like a desktop computer you may require a large UPS or one where you can add batteries to increase the time, but they are not inexpensive.

[worldscolide]

First. Most UPS's ( i think thats what you meant, Uninterruptible power supply) that you buy from stores not only aren't designed to last that long, they simply can't. They are designed to last on average 15 minutes at the most. The only ones that i know of that will last longer than that are commercial ones that are multiple thousands of dollars each. The result really would not be anything different than if the power did not go out.

Their purpose is to keep your computer running when the power goes out for a specified period of time. Thus it all depends on the battery sizes... A really cheap one might run your computer for 2-4 minutes. A more expensive UPS that you might see in a home solar set up might run your computer for 48 without issue.

As for it running just your router as mentioned below, look at the back of your router and check the amperage. Most likely it is about 1 amp. Watts = Amps x Volts. Your house voltage would be 120V in the USA so you're roughly using 120 Watts per hour. UPS designed for computers are generally rated to handle 300-600 Watts over a period of time. Thus you can likely take the time it is mean't to run a computer and double to quadruple that time to run just a router.

She's using a 12 VA 4 A router if I don't remember wrong from my conversation with her.

[Losalt]

Also, she's not in the US.

[Losalt]

I believe her local power is 115 V.

[Losalt]

And 60 Hz.

[Losalt]

And also using socket A and B.

It depends which gadget you are using to get power supply through USP. i have used USP for 3 hour non stop but I used for laptop charging so it goes that much long and ultimately using long USP batteries will drain eventually

[red324]

Sure would be nice to be able to keep the clocks from going out on the microwave and oven and the clock by my bed. The microwave and over are both plugged in inside the cabinet I believe though so probably not really practical

In a power outage, your router shuts down (no internet connectivity) even though your laptop PC continues to run on its internal battery. Unless you have a UPS on the router, or a whole-house generator, all you can do is work offline.

[Jim___Blakes]

You mean UPS? Mine works for only 30-40 minutes without power.

[exitseven]

The whole purpose of a UPS is so that if you get a power failure you can continue to function.

[LovingLoverReturned]

Where do you get this information? I read that it is so you can save your work.. which literally takes minutes to do

[exitseven]

A UPS can automatically back up your work and do a controlled shutdown of your system but it can also provide power for your system so that you can continue to work. UPSs come in different sizes and capacities. You can get one to suit your needs.

[DWornock]

The battery runs down and it shuts down anyway.

[Aakash_Hangargi]

Ups can work for 6hrs so not ab issue

[Losalt]

*Some* can.
There's also some that don't last as long, one I've been considering buying lasts 2 hours.

[LovingLoverReturned]

@Losalt I read that they are meant to last 10 minutes at most... but is that just the recommendation? I only want to use it to power my internet (router) for work.. and I only need 2 and a half hours at most

[Losalt]

@LovingLoverReturned
Just make sure that you find one that's rated for what you need it for and you'll be fine. :-)

[Aakash_Hangargi]

I am talking about invertor actually , his right UPS can come till 2hrs when they are very new

[Losalt]

Invertor?

[Aakash_Hangargi]

Never heard of invertor? Its like dad of UPS

[Losalt]

@Askash_Hangargi
Nope.
