This company makes better chargers than anchor. You should watch that channel that gets quoted all the time here where dude with four digital measurement tools always puts the basis above the anchor and for 40 bucks. What do you expect? I just paid $52 for it last week so he uses his reference 100 w basis. Gan power strip with two USBCs and tsbas as his top reference 100 w charger and sadly you can't get those anymore but baseus is kicking the asseus off Anker... So you can't get the full 140? What do you expect for $40 brother?
You going to get a anchor prime 20,000 milliamp for $40? I don't think so. Try like $100.
You're going to find false in all of these so we go milliamps per dollar and you're getting A good deal and some of us don't need to be jamming 140 w at one time into a MacBook. People here are so negative. Go look at the review on that. 240 w Anker prime if you want to see a power bank get tore up from the floor up
How does this compare to alternatives? The price looks really good.
I got one of these the last time they were on sale for $45. Works great for fast charging my laptop on the go. The display is nice as it shows the battery remaining, wattage being used and time until empty at current usage. I'll probably grab another for my steam deck

This one says 20000mAh in the title but 27000mAh everywhere else, not sure what to make of it.
Here's another one that (imo) has a better display, better power output and distribution when using two ports, seems to be generally better reviewed, and includes a 240W cable as opposed to a 100W cable: https://www.amazon.com/dp/B0F5PSC...title&th=1
There was also an SD post about it earlier that brought the price down to $47: https://slickdeals.net/f/18879031-prime-165w-total-asperx-20-000mah-74wh-laptop-power-bank-45-free-s-h
This one, however is definitely only 20000mAh (though there is a more expensive option that is 27000mAh).
Bought one earlier this year at similar price - this has been a beast. Use it to feed my awful Dell work laptop and it has been able to provide full charge (95w) to extend the battery by a couple of hours.

look at one of the video reviews, its 27000 mAh (max 165W).
AsperX (max 165W) is only 3 outputs just like this. AsperX cable looks fragile, honestly.
Baseus (max 145W)/Anker (max 165W) have 4 outputs.
Honestly, if you want included cables, why not just go with Anker then? I think one of the cables look the same and the other look much more sturdy.
Does anyone know about pass through charging in these products?

I just clicked through this again and now it says 20800mAh? Not sure what's going on there. I agree with your points, however those considering it may want to note the following, which may or may not matter depending on the usage scenario:
This power bank has four ports, but two of them are USB-A. In my case, I'm using USB-A less and less as everything switches to USB-C so I generally prefer one USB-A and the rest USB-C if possible. That said, it's true that the one I linked to only has three ports, so this is at least equal.
The cables don't really matter, I was just pointing out that, all other things being equal, the cable was higher wattage than the one that comes with this bank.
Not clear what the warranty on this one is, the one I linked has a 2-year warranty.
One thing that sucks about these banks, including the one I posted, is that the power distribution is really lop-sided when you use all the ports. For example, for this bank, one pair drops to 15W max combined with the worst case being only 15W and 33W output. In the other cases, one pair can only put out 15W max combined between the USB-A and USB-C ports. For the one I posted, if you use all three ports, then the second USB-C port and the USB-A port can only put out 15W combined, which is absolutely terrible. This results in your laptop charging at "normal" speed while the other devices charge excruciatingly slowly.
The above point is really thorny in practice, because it's hard to predict the charging rate of the ports in normal use. I often end up in a situation where I'm waiting a long time for some of the devices to finish charging.
I'm a bit obsessive about these power banks due to the number of devices I typically have to charge, so I did a bit more research and came up with the following:
I decided to go for a bank that shows the input/output for each port, so you can know the rate of charging for each device.
Due to conversion losses, these banks only give you 2/3 - 3/4 of the total capacity. For example, for the one I linked to, there is a note on the page that says: "20,000mAh is the battery capacity. The average energy loss on the market is 30% to 45%. By upgrading the components, we have controlled it to 20%-40%, so a full charge will provide 12,000 - 16,000mAh."
Because of conversion losses, I decided to go for a 27K mAh bank, which is the max allowed on planes.
Based on the last points, I found the following banks which fit the requirements above (they all have 27K capacity and displays that show per-port charging rate):
These both have middling reviews, and the reviews on the second are all Vine reviews, however one of the reviewers posted detailed measurements, so I decided take a chance and see how it goes.
