Anker 737 Powerbank With XPS 15?

Who here has used this anker 737 powerbank with their dell xps and particularly with the dell xps 15?  I have a dell xps 15 9520 with i7-12700h processor and nvidid 3050 and 32gb ram.

It has 24000 mah which is more than any powerbank out there that you can carry.  I also have the Dell PW7018LC powerbank to use with my xps 15 9520 and when laptop is full battery 100% but I unplug it from outlet and plug the Dell powerbank to it, it lasts 50 minutes before it goes out.  Again this is assuming my laptop battery is 100%.  

Has anyone here used this and if so, how long does it last?  Seems like 1 hour 5 minutes before it goes out but that's only if you connect it to your laptop when battery of laptop is 100%?  But if your laptop has say 10 or 20% battery only, it will last shorter since it uses up more battery bringing the battery up while you are using it... correct?  So the Dell powerbank might last 40 minutes or so but raise the battery from 10% to 40% at the most?  

Now with the anker, what about that?  I know it advertise 140w but non dell chargers and powerbanks I read it can only do 90w or 100w?  My xps 15 9520 has 130w charger.  The Dell PW7018LC powerbank is 65w only so when I connect it to my xps 15 9520, it says slow charging but it does work though.  Also... the Dell powerbank does get really hot.

Anyone have experience with the anker 737 with the dell xps 15 and if so, experiences?  How long does it last before it goes out?

Too many variables to answer.  With the nVidia GPU disabled, you'll get far better battery runs both internal and external -- that is the biggest consumer of power in the system.  The capacity of that Anker power bank is enough to charge the larger of the battery options for that system (which you probably have) about three times.

No battery, internal or external is going to power that system at anywhere near full speed -- for that you need an AC adapter connected.

Do you actually need to manually disable the nvidia gpu though?  Or it's fine using the laptop as it is since normally it won't use the nvidia and uses the intel iris xe graphics?  But doing that would make the powerbank last longer or not?  But doing this requires you to do this on Bios or it can be done in start menu somewhere?

The anker 737 has 24000 mah.  Do you have any idea how much wh that is?  My xps 15 9520 has a 86wh battery.  

Well the Dell PW7018LC I used which has 18000 mah which is 75% of the capacity of the anker 737 only lasts 50 minutes before it goes out.  So how would this anker charge the system 3 times?  There is no way it can even charge my xps 15 9520 one time.  I don't think the anker 737 can even charge a macbook pro more than 60% probably.  So how would it do the xps 15 9520 3 times?  Can you explain to me what you mean about 3 times?

Well assuming you aren't using the nvidia 3050 and only using the intel iris xe graphics, it still probably give 1 hour 5 minutes or so before it goes out?  Now let say I let my laptop down to 10% battery.  If I connect the anker 737 to it, how long before anker goes out?  How much battery percentage will the xps laptop go up from 10% to how much?  I got to assume maybe 50 minutes and not 1 hour 5 minutes since it is going to use more battery making the battery go up and also since it is in use?  And the laptop battery goes fro 10% to maybe 50% at the absolute max before the anker 737 goes out?

If it runs your system at the same 11.6 W the internal battery does, 24000 mAh * 11.6 /1000 = 278 W Hr.

Hi.  I'm not sure what you mean with that calculation.  But it sounds right how much extra battery I get with the Dell PW7018LC right?

So the anker 737 won't be that much more extra battery?  1 hour 5 minutes compared to 50 minutes or so?

@ejn63​ 

I just bought the anker 737 and got it. It came with less than 20% battery so I have to charge it. The thing is it only comes with 1 cable?  How am I suppose to charge this to an outlet then to 100%? I read online people use a pd usb c charger or a magsafe charger? I don't have either of those. I need to buy another cable or power adapter in order to charge the anker 737? Could I use either my Apple 20W USB-C power adapter that I charge with an iphone 13 mini with this? I also have a very old 5W usb wall charger that I use to charge with old my iphone SE. Would the 20W work? But it charges slowly? I had no idea that this anker 737 didn't came with a charger to connect to an outlet. Seems ridiculous that when I read online people use a pd usb c charger or something similar and have to pay for another item to use with this anker 737?
 

I have the dell xps 15 9520 laptop and it charges usb-c and the dell charger is 130w. Can I use that or not?
 

It only came with one cable. The cable that is supplied in the box... that is meant to connect to your laptop that has a usb c port to charge right? Then how would I charge say an iphone 13 mini? What about an old iphone se? Also what about the other end of that one cable?
