    I have a dell xps 15 9550. I have a dell powerbank PW7015L 18000mAh. It is compatible with it. When i charge my laptop when battery is say 10%, it would take around 1h50m to charge before it runs out of power. Laptop charges probably to 70% or so.

    Can someone tell me if this powerbank is compatible with


    1. XPS 9560
    2. XPS 9570
    3. XPS 9580



    Also does anyone here have the dell powerbank PW7015M? Its 12000mAH. Can someone tell me if its compatible with my laptop the xps 15 9550? Also what about the 9560, 9570 and 9580? I know you get much less power from it but you can still do your thing while charging it right? For example I believe certain powerbanks... you cannot do anything on laptop while charging it... thus you can only charge it and cannot do anything on it.



    The reason why i ask this is because i might sometime later on get a new xps whether its the 9560, 9570 or 9580 and want to know if my current powerbank PW7015L is compatible with all of them or not.


    Also there seems to be a Dell Powerbank Plus USB C PW7018LC. Is it compatible with any of the xps 15? If so, which one? On the dell site, it only shows compatible with the xps 13. It shows 18000mAh so its the same power as the pw7015L right? It does say 65W. But how much watt does the pw7015L has?

    A quick google search shows the PW7015L is compatible with the 9560. It would likely work on the 9570, but doesn't list it (probably because it's an older battery). No one knows about the 9580 because it's not out yet.

    The PW7015M is NOT compatible with any of the XPS laptops.

    The PW7018LC does not list compatibility with any of the 15" XPS laptops but would likely work since they work with USB-C charging.

    The PW7015M/MC are not listed compatible with XPS 15 but I recall some reports they did kind-of work, but less than half the full battery charge so not much point.
    XPS 15 minimum requirement seems to be 45W at 20V (for restricted-power mode). Dell doesn't widely list power ratings but I recall the PW7015L is 90W plugged-in / 65W power-bank. 3rd-party USB-C 45W reportedly mostly fail.
    XPS 15 kind of "prefers" USB PD 60W @ 20V 3A, and the number of 3rd-party chargers is increasing recently (capacities mostly around 27000mAh). Better check for reports of XPS 15 compatibility though.

    Hi there. Yes i read it works with the 9560. But the 9570, i recalled someone mentioned it does work but not sure it that is confirmed or not.

    On the dell site, it says pw7015M is compatible with the 9550 and 9560.

    Hi there. Well it shows xps 9550 and xps 9560 compatible when i check it on the dell site with the pw7015m. But yes i know it would not give it that much power. But if it works, that is what i want to know.


    Can anyone here who has the PW7015L or PW7015M confirm it works with the 9560 or 9570? Also anyone here can confirm if the PW7015M works with the 9550? I have the PW7015L and it is compatible with the 9550.


    Also quick question on this. If i were to get 2 more PW7015L that is 18000mah each so total would be 36000mah... as compared to say 3 PW7015M which is 12000mah each... if say it cost less money to buy 3 of the PW7015M as compared to 2 of the PW7015L, i should get the PW7015M right? Because they all add up to 36000mAh? Or is that logic wrong? Obviously each pw7015m will last shorter than the pw7015l but when you add them up, it should be equal?


    Also i'm asking this because if i were to get say a 9570 or 9580 in the future, i would want to know if my PW7015L and if i get PW7015M, if it would work with the 9570 or 9580 so that way... i know i have backup powerbanks that would be compatible.

    Wait doesn't those things not work with xps laptops because it doesn't have enough volts or something like that?

    Well isn't getting 3 M's the same as having 2 L's? Thus the M's are 12000mAH and the L's are 18000 mAh? Or does it not work like that? I already have one of the PW7015L already but want more battery backup.


    Does anyone know if the PW7015M can be used while charging it? Example battery is 10%, you charge the 7015M powerbank to it... then use it while its charging? Or you cannot do this? Or you can but there are issues with this? There is no issue with the PW7015L when doing this.

    Nope, USB-C 60W @ 20V 3A should work (but check manufacturers claims and XPS 15 reports). Though in a restricted mode. But the L feeds just a few more watts when not plugged in. The M feeds less.
    Of course, most USB-C PD powerbanks don't supply enough power and 20V voltage, because they are meant for phones.

    The smaller banks aren't going to be enough to charge the laptop while it's "running full tilt." My 65W chrome usb-c adapter isn't enough to charge the laptop while the cpu is running 100%.
