    Typical power outlet (the thingy on the wall you plug electrical things into) has one contact (wire) for phase, one for neutral and one (usually in the middle or side in Europe) is for ground and that literary means connected to metal stuck in the ground somewhere down the line. It's there to protect you from shorts to the case etc. If anything happens, electricity goes to ground instead of shocking you.

    Well the outlet has like 3 things to it...that you can plug it in perfectly.


    So pug it in wall outlet the ups and im good right? Well i mean im concerned if say im charging it for a few hours... then power outage. MY UPS will still be okay right? Because for example if i connect a monitor to the wall outlet and power outage happens, well my monitor can be destroyed... But UPS not right because the ups has surge protection?

    Power outage is not going to destroy anything, it will just shut it down until power's back. Power surges are also rare, worst ones are if a lightning strikes cables bringing power in the house. Building you are in hopefully has protection for that. Just plug it in, turn on and let charge overnight before you connect anything to it or it will probably complain loudly that battery is flat. There's nothing more to it than plugging in TV, toaster or desk lamp.

    So Im charging it right now still.



    Do you want me to remove everything from my power surge and connect everything to the UPS then? So no use of the power surge anymore?



    But wouldn't this mean my electricity bill usage would be higher having everything connected to the UPS as oppose to the power surge? Also wouldn't it mean my UPS would not last as long this way? Thus if i use the UPS as least as possible such as only when i need to... then it would last longer? Or is that incorrect as well?


    Also i watched a video on the cyberpower and a bit confused. Its the same model but smaller VA. This person was connecting monitor to the back of the UPS that has the surge/battery on it. But the laptop, he says you can connect on the other side which is only surge because laptop has battery itself. Then i notice they started connecting the ethernet from the modem/router to one of the back ports. Then also connected a telephone jack to it. Im confused with the last time parts... the ethernet cable and telephone jack. Because when i look at my power surge, i have the modem/router connected to the power surge and also the telephone line but the plug in. Why in the world did the person in the video connect the ethernet cable and phone jack to those ports in the back of the UPS? Why doesn't he just connect the plugins that are connected to say the power surge to the UPS Im very confused with why this person does this.

    Buts it fine doing what i want right as oppose to what i posted above? Charge UPS to 100%. Just leave it under the desk.


    Have everything connected to the power surge as i always do. And if there is power outage, just connect my laptop ac charger to the back of the UPS when battery is low and then use it while charging it right?


    Because the setup i have now with everything connected to the power surge, is fine and when there has been power outages, my monitors have had no issue etc.


    Also what if i only use like 15 minutes of the UPS and then no longer need to use it if the power come back? Always make sure its fully charged to 100% right? So whenever i use it for 10 minutes or 30 minutes, always charge it fully?


    What is also confusing is they supplied me with a usb cable. I took a look at the video and it seems thats to connect the UPS to the computer and i saw it was done in a video with a desktop. So doing that with my laptop is necessary? Or its just good idea to see how things are but not necessary?


    Also i have to download the cyberpower program first here?


    Software | CyberPower Systems



    But this is not necessary... its just if you want to monitor it through your laptop or desktop right?

    Just leave whatever battery backup system you have plugged in to AC power. You want the battery to be at 100% charged when the power goes out and that is how you do it. Do the manufacturer's instruction say to charge the battery then disconnect the unit until the power goes out and hope you have a charged battery when the power does go out? I seriously doubt it. Just man up, plug in your USB into an AC outlet and leave it there.

    Yes i want the battery to be charged at 100% so i can use it at 100% when power goes out. It says to charge it fully for 8 hours which i did. It says to keep your devices connected to it.


    So if that is the case, if i were to not use my power surge, basically connect everything to the UPS but on the other side that is surge and not power right? Also if there is power outage, i plan to use my laptop battery first. I want to use it for 1h15m or however long it is before i connect it to power source. So if i use the UPS, i mean i could connect everything to the surge only right? Example, laptop charger, 2 monitors, modem/router etc? Because if i were to connect the monitors to the other side which is surge and battery, then the moment power goes out, im going to have to remove the monitors from the battery side since i dont want 2 monitors draining the ups battery power for a minute or two... does that make sense?


    So basically connect everything to the UPS, but just connect everything to the power surge only right? Or only do the laptop on the power and battery because once there is power outage, i can just unplug my ac charger from my laptop while its connected to the UPS still, use it on battery till low percentage, then connect to it right? So that means i have no use for my power surge then? I liked the power surge a lot as it has served me well.

    Okay its fully charged. The moment i connect my laptop charger to it with my laptop, it shows about 250 minutes. This is when i have tons of chrome tabs on and programs but not playing at the moment. I then connected one of my monitors there... so its my laptop and monitor... showed estimated time of about 135 minutes or so. So basically thats how much there is assuming you just leave it while using it unplugged.


    So right now what I will soon do is unplug the UPS from the wall outlet. Thus it would be like as if im doing a test if there was no power. Then use my laptop on battery to see again how long battery last... it should be about 1h15m before battery gets low on laptop before i connect it to the UPS. Then connect the ac adapter to the UPS. Then continue doing what im doing... however when i do this, imnot going be doing as much i normally do since im paying a lot more attention to this. Then see how long it takes to fully charge my laptop to 100% if it does. Then see how much percentage i still have left on the UPS when this happens. But continue to do my thing until the UPS runs out of juice and it powers off itself right?



    Then after this, then i know how long this UPS gives me? Then i get another 1h15m on laptop battery again.



    The other questions I have is this. I will do this test a few times. But everytime i do this, as in use my UPS with my laptop and use the UPS till it turns off itself, is this going to wear out my UPS much faster? Is there a difference between someone say having their desktop and monitor on the entire 1h30m and do nothing on it or do light stuff on it like just play music or something... compared to me doing my thing and using more power and then it turning off itself when it runs out of power?



    Should I immediately turn off the UPS at like 5% or something if it makes the UPS not wear out? I know these things last a while but i dont want to wear out the battery after say 5 times bringing it down to 0%. Is there harm in this or not? I don't want to wear the battery out in a few instances only but for now, im testing to see how long i can get while connecting laptop to UPS... then try laptop and 1 monitor with UPS ... and maybe later laptop and modem/router.

    Also on that screen on the UPS, it shows numbers for these things below


    estimated time remaining
    voltage input
    hertz input
    voltage output
    output kw
    output va
    outva kw
    kw%
    va%



    I then connected my laptop to it. I also unplugged both monitors from my laptop. I closed all my chrome tabs for now but have lot of other programs on but im not running them.


    This is what i shows on my cyberpower ups 1500va/900w



    estimated time remaining 265minutes

    voltage input 118v

    hertz input 60

    voltage output 117v

    output kw 0.027kw

    output va 32va

    outva kw 0.1 or 0

    kw% 3kw%

    va% 2va%




    Do these numbers look right for my xps 15 9550 laptop? I remember people talked about you need to calculate how much watt or volt your laptop draws an hour and people guessed for 50 for mine because its a quad core. So does the output kw or output va show that number?


    Obviously when i start doing my thing, there would be more power used but does this look right to you all? Again, this is only my laptop connected to UPS nothing else.
