This used to exist, the Lenovo USB-C Laptop Power Bank was 290g but it's discontinued. The Omni Mobile 12800 was 270g but it's discontinued as well.

What alternatives are available end of 2023?

The Nitecore NB20000 is 324.5g, I wonder whether we could do better.

  • By 45W, do you mean 45W of maximum power output or 45Wh of capacity?

  • 45W power output.

Zendure SuperMini X3 10000mAh

45W Power delivery output, […] weighs only 200g

And this one is actually available right now although the US is crossed out and only CA shows availability -- Canada I guess.

There's the Elecjet Apollo Pro and while I can't find the exact weight it stands to reason this 9000mAh power bank can't be much more than 200g either. Alas, it seems to be a Hong Kong exclusive. The Elecjet Apollo Ultra has received widespread praise (or perhaps it's just puff pieces? hard to say but there are some positive posts on reddit too) but it seems it's no longer available either.

Another would be the Excitrus Power Bank Air but is also gone so much so the myexcitrus.com page is now a parked domain. (I have an Excitrus 65W charger and it's great, verified by a teardown review.)

4Smarts has a Power Bank Pocket Slim 10000mAh 45W and I see a a few French sellers on eBay. As a bonus it even supports through charging although this image suggests it only charges at 27W while discharging at 45W. The page doesn't have the weight, amazon.com claims 6.7oz or 190g.

  • I saw. Much as the other two I listed it's unavailable. So is the Elecjet Apollo Ultra. But I do have a solution I just found, let me post it.
