Laptop Powerbank Compatibility With XPS Laptops

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.

 

Don't buy M. The current drain is high relative to the capacity.

Check this or sth similar (you might need a suitable USB-C PD charger too):
https://www.amazon.co.uk/FLOUREON-26800mAh-Delivery-Portable-Nintendo/dp/B07KYBBHKT/

 

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%.

 

Are you talking about the link you posted above that is the usb-c 60w?

Well can anyone here confirm what you posted would work for the xps 15 9550? From what i researched in many articles online, the only 2 options are the pw7015L and maybe the pw7015m because it states on dell site the M is compatible.

 

Which xps 15 specifically do you have? 9550, 9560 or 9570? When you say full tilt, you mean when the computer is running close to 100% So if someone has 40 tabs up and only uses say 10 tabs while web browsing whole time, is that considered full tilt?


Which usb-c adapter are you talking about here? Are you talking about that pw7018lc?

 

I've had 9550s, 9560s, and 9570s, and 65w was not enough to run the cpu at 100% on and charge. I'm not specifying what full tilt is because you're the one that keeps using the term. Yes I am referring to the pw7018lc that you were asking about.

 

Hi there. So you had the xps 9550, 9560 and 9570. How many different power banks did you have total that you used personally?


So you telling me the pw7015M which only has 12000mah would not work while charging the laptop and using it? Or it would work while using it as long as the cpu is no where close to 100%. Example say it was at 50%... would it charge your laptop while you are using it? Or it only works if you are either using it very light or have laptop turned off?


Well with my xps 15 9550 and at say 10%, the pw7015L which has 18000mah would charge about 1h 45m before it runs out... and my laptop would have at most 70% battery. Thus my laptop gives me about 1h 15m battery at the max... and the pw7015L gives me another 1h 45m... then my battery would last maybe 45m to 50m... so in total i would have 3h45m at the most with my laptop on battery, then connect powerbank to it while using it... and then using my laptop on battery again.


Did you ever try the pw7015L though?


Can anyone here confirm the pw7015M would not be compatible with the xps 9550 or 9560 because they can't use it while using the laptop at the same time? This is what i want to know.

Okay say i want another 6 hours of backup of battery. Is my option basically buy a few more of the PW7015L and thats it?


What about UPS? I check online and they have those cyperpower 1500v UPS. Does anyone have a clue how long a UPS would last? Example my xps 9550 would give me 1h15m battery, the powerbank would give me roughly 1h45m... then my battery would give me another 45m to 50m. But the most important thing is the powerbank charges my laptop while im using it.


Would a UPS fully charge my laptop to 100% while im using it? How long would that take? My dell powerbank pw7015L charges my laptop to 70% max after 1h 45m. I assume a UPS would give me a bit more than that?


In terms of price... which is the cheaper option? Get 2 or maybe 3 more of the pw7015L or get maybe 2 UPS? I want an additional 6 hours of backup battery for my laptop.


So i just want to make sure the PW7015M is not an option first. Because from checking online, the price of getting say 3 of those pw7015m which as 12000mah is cheaper than getting another 2 of the pw7015L.


Would like all of your opinion on this.

 

Can anyone here confirm if the pw7015l works with the other models such as 9560, 9570 and 9580? I might get another one of these... and i like that in the future if i get another xps... that i can use it for that xps laptop.


Also anyone know if the pw7015m can be used while charging it? Thus laptop has little battery... connect the pw7015m to it... while you charge it and continue using it?

 

It was already mentioned that the pw7015l is listed as compatible with the 9560, and I've already speculated that it would work with the 9570 since nothing changed with the power requirements between it and the 9560. Nothing seems to have changed power wise on the 7590 so it should work on that as well.

I do not know the answer to your question about the use of the pw7015M while charging. Again, I don't know how long your system will last on these power adapters since you are running it "full tilt."

 

Hi thanks for that information. Does anyone here who have this powerbank can tell me if it works with other xps systems such as the 9570 or 9580 etc? The reason is because I don't want to get a few of them... then if i were to upgrade to a different xps, the pw7015l is no use for me.

 

Hey all. Its been a while since i charged my dell pw7015l companion and i notice it is not fully charged.


To charge it, you are suppose to unplug the ac adapter that is used from your laptop and unplug it from laptop and then plug it into the pw7015l right? I then unplugged my charger that is connected to my xps laptop and then plugged it to the powerbank. Is that the correct way to do it? I done it few times but it's been a while since i had to recharge it and im not sure 100 percent if this is the correct way or not. I know each time you do it, you wait until it shows 5 lights etc.


Because i thought i remembered when i did this earlier, my ac adapter was connected to the powerbank and then the powerbank was connected to my laptop. But there are 2 ways of doing it right? Thus the first way is if you just want to charge your powerbank... and then either you use your laptop on battery or not have your computer turned on at all... or have them all connected to one another so basically it first charges the laptop first to 100% if its not 100%... then it would then be charging your powerbank?
