First thing to keep in mind is that some of these Chinese power bank ratings are grossly exaggerated. They have no shame scamming people. Project Farm in their recent battery bank shoot out found the worst offenders only delivered 28% of their promised capacity.
Second, there's going to be a power loss due to overhead and heat. You're never getting back from the battery exactly how much you put in. People claim about 15-20% loss in energy stored.
Finally, mah rating alone doesn't really tell us how much energy there really is. The best way I can explain is using water as an example. If I take two pipes and fill them both with water. One pipe is twice longer than the other pipe, does it mean that I can fill the short pipe two times with water from the longer pipe? Of course not. Shorter pipe could be 3 times as wide as longer pipe. We not only need to know the length, we need to know the width or diameter of the pipe. Once full dimensions of container are known, we can calculate how many gallons or litters it holds and can compare the two and truly see which one is bigger and by how much. So in this case mah rating is like length of pipe and voltage rating is like width/diameter. We multiply voltage by amps and we get watt-hours or Gallons in my example. A quantifiable amount of energy stored in any battery that lets us compare them irregardless of their voltages.
Another way to think about it is gas cans. If I tell you I have a 5 gallon gas can you have a concrete idea of how much gas it holds. But if I tell you I have a 12" gas can you really have no idea, it could be 3 gallons, it could be 10 gallons. Mah and voltage rating is just dimensions of the battery (container), Watt-hour rating is the actual capacity.
Lithium-ion cells run at 3.6-3.8 volts. Anker rates their power bank at 24000mah at 3.6 volts. 24000 mah is 24 amps. 3.6v x 24amp = 86.4 Wh. According to Project Farm testing, Anker 737 delivered 69Wh or 79% of its claimed capacity. So it's more like a 19000mah. It's not horrible IMO compared to some other brands, it wasn't the most honest power bank on the list, but I think it's still pretty good. The best one on the list did 89% of claimed capacity. Anker may also have the most overhead consumption with that screen.
Steam battery is rated at 5200mah at 7.7v. "Pipe diameter" of steam deck battery is twice as wide as on Anker 737 and will require about 10400mah at 3.6 volts to fill it. Deck's battery is really just two 3.6v 5200mah cells linked together on the inside. 7.7v x 5.2amp = 40Wh capacity. That's almost half of Anker 737 rated capacity. Project Farms claims it has 69Wh capacity so I suspect you will not get another full charge even though your Anker showed 50% left, probably a 3/4 charge left.
Take anker 737, chop it in half with an axe, that's literally how much battery is stuffed into LCD SD. OLED SD is even better at 50Wh.

Ok, I'll see myself out
EDIT: Forgot to say, all these companies should really advertise Wh instead of mah on their power banks, but you know, 86 is just not as big or cool of a number as 24000!!!.
I've bought two of them about 6 months apart. First was $50 and included a 100W GaN charger and the second one I just purchased last week was a little over $28. Incredible deal for a 25000mAh 130W Output power bank. Just have to watch the product as the price fluctuates often to catch a deal.
In any case, it's worked great every time I use it. I don't have any devices that take 130W over USB-C but have confirmed it at least does 100W. It's only 1" thick and is 5 ounces lighter than this Anker. Not as much tech info on the display though, although I just need to know the watt draw and power remaining.
Anker, of course, is a trusted name. Worth the extra $$$ ?? Probably to most. But I like saving money too.

I'm curious if owners are experiencing the same losses. The readout says 100% battery health.
I have other much less expensive Anker batteries which stop working as soon as you plug them in.

I hope that someone with this pricey powerbank can help you out.

After reading a few noticeable 1-star reviews, I decided not to pull the trigger.
Especially one of the reviewers lost his LG Gram Laptop and iPhone. This power bank toasted the LG Gram motherboard and almost did the same with the iPhone.
