    You want as little as possible connected to UPS, just minimum you need to keep on working in case of power outage so charge lasts as long as possible. The rest leave in surge protector. Don't know about that particular UPS but many have an USB connector to computer which with right SW can show you battery charge % and /or safely shut computer down when charge is at lowest point.

    Stop overthinking this Pauly.
    You plug the UPS into the wall.
    You plug the computer stuff into the UPS.
    You're all done. Just use the computer.

    There is nothing else to look at.
    There is nothing else to be concerned about.
    There is nothing else to report.
    There is nothing else to do.

    Hey all. I will most likely get another powerbank.


    But want to know the answer to this.


    No matter what country i buy the powerbank such as the pw7015l, it works the same regardless right and is the same exact product no matter where its sold at? For example if you buy a laptop in another country, well the language and keypad of it can be different. Example it could be in spanish or another language.


    But when you buy a powerbank, its always the same product regardless right? Like the cable will match the laptop?

    Output plug has to match that of laptop but if it's charging thru power adapter. that one has to match voltage in your country, 110 or 220v although there are chargers/adapters that can work with both.

    I wonder how Pauly buys milk at the supermarket.

    "This one says skim.
    This one says 1%.
    This one says 2%.
    This one says whole milk.
    Does it matter?"

    "How many % in whole milk?"

    "The whole milk jug has a red cap.
    Why does the 2% milk have a green cap?
    And why does the 2% milk at another market have a blue cap?
    Does it matter?"

    "If I mix 1% milk with 2% milk does that produce 3% milk?"

    "This brand has a screw on cap.
    This other brand has a lift-off cap.
    I heard that the lift-off cap causes cancer.
    Is that true?"

    "Why is milk white?
    Is it okay to drink blue milk?
    Where is blue milk produced?
    Maybe I'll have to drink less white milk and more blue milk."

    You'd actually get 1.5% milk assuming a 50/50 mix.

    (v1c1 + v2c2)/(v1+v2) = c3

    Where v = volume of milk added
    c = concentration

    But the real question is what color cap does the mix get? If the 1% milk has a yellow cap, and the 3% milk has a blue cap, does the mix get a green cap? And are the yellow, blue and green caps all compatible with my milk jug?

    Hi folks

    remember an old TV series "The never ending story of Peyton Place" or was it just "peyton Place". This thread seems to be going in that direction too.

    I think from the question about milk in the above section -- what's the brand of COW and which farm does it come from !!!!

    Cheers

    Dell defines what its PW7015L powerbank is. Dell defines whether or not the PW7015L powerbank is compatible with various computers. Dell's PW7015L powerbank provides the cable that connects the powerbank to your computer. If a seller claims to be selling Dell's PW7015L powerbank then they are claiming to sell exactly what you already have.

    You can go back to
    Dell Notebook Power Bank Plus (18,000 mAh) - PW7015L
    [that's a UK link, you can then use the country selector at the bottom of the page]
    then search for info about any regional variations you think might exist.

    I have never noticed any information about regional variations. There is nothing in the user guide that you also have a copy of [and that you can also download from somewhere in the Dell website].

    If you are still worried then use the blue We're here for you tab on the right-hand side of the webpage [in the UK webpage at least] to chat with them or send them an email.

    If you do contact them I would also suggest getting confirmation that the powerbank is compatible with your computer.
    - I appreciate that you now have experience of using it but their opinion would be useful to have, I would have thought.
    - Since you stated a little while ago that your AC power adapter can supply up to 6.67A at 19.5V then I fail to see how the Dell PW7015L powerbank can fulfil your needs given that it can only supply 4.62A at 19.5V.
    - - Perhaps it can only both power your computer and charge your battery under certain conditions, such as when the display is blank or when WiFi is not being actively used.
    - - Perhaps it can cope with both powering your computer and charging your battery but the charging is much slower than it would be by using your AC power adapter instead. If this is the only drawback then perhaps it is a limitation that you can live with.
    - - You can, of course, conduct your own experiments to find this out.

    I thought you had bought some other solution instead of another PW7015L powerbank. If your current concern is caused by not knowing how to set that up and use it then I would urge you to find somebody locally who can look at your equipment and explain it to you. Since you have spent the money already you might as well get the benefit of it.
