Compared to almost every other 20-26k power bank, this RECHARGES and does passthrough way better (140 recharge/100W passthrough)
- UGreen 165W can passthrough 100W max, recharges at ~60W average.
- Anker 165W can passthrough 65W max, recharges at ~70W average.
The only ones that come close are Anker 250/300, Ecoflow 300, and Cuktech 15.I know that when I connect it to my xps laptop when my laptop battery is 100%, it seems to keep my laptop fully charged at 100% and it last 1 hour 5 minutes or so before it is done. Is that normal?
Do you actually get more battery out of this for your laptop if you connect this to your laptop the moment your laptop doesn't have any outlet to connect it to compared to when the battery is at 50% or 20%? I read it uses more power when it's lower since it has to charge the laptop and use more power? But most people use their laptop on battery and once they are low in battery, then they connect this to it right?

If you connect it at higher % on the laptop side, you're outputting less from the power bank, meaning less heat and more efficiency.
If you're looking for a full charge from 737, the laptop has to have max 65Wh battery (Macbook Air 15, Pro 14, XPS14/15).
If you want 2 hours of runtime off of a 737, M4/5 (non-Pro) Macbooks are the only one who will do it because the same work (Cinebench 2024 Multi) uses a lot more power on other CPUs (+25% for Snapdragon, +35% for 12th gen H series in your XPS)
Others online report same thing.
I want a power supply that has used changeable batteries!

Okay so you always lose some percentage with the voltage conversion. This applies to any powerbank or like jackery power station right? Now does this voltage conversion differ a big percentage if you connect the anker powerbank to laptop while battery is 100% compared to say 20%? When I tested it on laptop when laptop is at 100% and so is anker powerbank, it was about 1 hour 5 minutes. I think when I did this with the laptop battery is 20%, it might been 55 minutes or so. Would that be accurate? So it should not last 1 hour 5 minutes since it will use more power getting the laptop battery percentage higher compared to if laptop battery is 100% and the anker powerbank is being used until it's 0%? Does this mean if you planning to use your laptop for a few hours and you haven no outlet for a few hours, it makes sense to use the anker powerbank connected to your laptop while laptop is at 100% and use it all up to 0% and then use your laptop until your laptop runs out of battery? That would be better than using your laptop to 50% or 20% or even less and then connecting the anker powerbank to it? This is all assuming you are doing something on your laptop while the anker powerbank is connected during this process. When you say it uses less heat and more efficiency so you mean the anker powerbank would go a bit longer while connected to laptop right?
If that is the case, why do people seem to use their laptop while on battery and only when they are in low in battery, then they connect the anker powerbank to it? I guess it's because they want their anker powerbank still somewhat full for charging their laptop or something or assuming they will get access to an outlet soon or they going to be on their laptop for maybe an hour or so and thus want their anker powerbank to be full later on?

- Apple: M4 beats M1 Pro by 20% while using half the power
- AMD: Zen 5 HX370 beats Zen 2 9 3900 by 20% multicore while using half the power
- Intel 1270P still scores better than 268V and 12900H is about the same as 255H
Efficiency and longevity is similar between the banks:If you connected the 737 to your older Dell via barrel connector, you'd get ~2-2.5hrs because per Notebookcheck
- 9550 w/ i5-6300hq averages 70W on load, 114W max
- 9520 w/ i7-12700h averages 92W on load, 134W max
Efficiency and longevity is similar between the banks:Well I can't connect the 737 to my older dell xps 15 9550 laptop because that laptop uses a barrel and this anker is usb-c. I could buy an adapter for this though right? So if I did that, I get 2 to 2.5 hours compared to 1 hour 45 minutes that I got with the dell pw7015l 18000mah barrel powerbank if I use it for my older xps 15 9550? I was shocked that the anker 737 only got my newer xps 15 9520 laptop only 1 hour 5 minutes before the anker went off compared to the old dell barrel powerbank with the older dell xps laptop. I believe I could actually use the dell pw7015l 18000mah barrel powerbank with my xps 15 9520 if I buy the adapter right? But it would last 50 minutes?
I forgot to mention this. I also have a dell pw7018lc usb-c powerbank that I bought a while back as well. This is also 18000 mah. I bought this even before the anker 737 since my new xps 15 9520 uses usb-c only and this powerbank is usb-c. So this was my main powerbank for the xps 15 9520. I believe when my xps 15 9520 is 100% and then I unplug laptop for outlet and then connect the 100% dell pw7018lc 18000mah usb-c powerbank to my xps 15 9520 laptop, it was about 50 minutes before the dell usb-c powerbank went off. So that makes sense right?

For old power bank, you'd get 35 minutes or so with 9520... but no such adapter exists for 20V barrel to USB-C.
If you're looking for an upgrade, the Dell 14 Premium will bring you back to 9550 power consumption while being faster than the 9520.

Why would the old pw7015l 18000 mah powerbank barrel only get 35 minutes with the newer xps 15 9520 only? The current pw7018lc 18000 mah powerbank that is usb-c with the newer xps 15 9520 get 50 minutes when I tested it a while back. So wouldn't the older powerbank that is barrel and same mah be the same though?
Are you sure no adapter exists for that? A while back on dell site, they had an adapter like that but now it doesn't seem to be available anymore. I checked ebay and pretty sure it looked something like this below. So this wouldn't work? The one on dell site a while back looked like this.

The thing is if I get a new laptop, I don't want the laptop to be smaller screen size. That laptop you mention is interesting. It's a faster processor and has 32gb ram and has a 4050 which is similar to the 3050. I am surprised that it would get back to 9550 power consumption. What is the reason for this? Which configuration of the dell 14 premium are you using for this though? If it's the one with a 4050, it uses a 3200x2000 screen OLED screen so isn't that screen going to use a lot of battery? Can you ever turn off the OLED like how turn off the 4050 graphics card or you can't do that? There is one with the ultra 5 processor but it's 16gb ram only and intel arc graphics processor but does have the 1920x1200 display. Are you talking about that laptop? I thought that is strange if you are talking about the one with the intel ultra 755h processor, it would get more battery with the powerbank since it has the OLED screen but that isn't true?
