Help me buy a second charger for my laptop

I'd like to get a second charger for my laptop, a Lenovo Slim 7 Pro X. What should I buy?

I've never been great with understanding computer power components. I don't love the design of the official Lenovo charger so if I can get one that's a little better designed, I'd be all for it.

If I search for "lenovo Slim 7 Pro X charger" on Amazon there are a bunch that show up with random letter brand names. Some have more than a few reviews. Most seem to be only 65W when the one that came with my computer is 100W. Is 65W enough? Is 135W too much? Are there off-brands that are cheaper than the official Lenovo one which are trustworthy enough to use?

Or should I just buy another of the official Lenovo chargers?

I would say "just buy a good USB-C charger" but apparently a 100W USB-C charger is insufficient in some situations and it seems like it struggles to pull more than 100W even from chargers that are supposed to support it.

If you're not running it at full performance mode though, a 100W USB-C charger seems like it would be enough and a 65W charger might not be.

if that video is representative: strictly speaking, you'd want a 135W charger that it can actually charge from, to use it at its maximum settings for any length of time, but a 100W charger would probably be fine otherwise, since it seems to max out at 104W.

This claims to be exact replacement for your charger.

Best answer: I haven't used this specific one but this one is a 100W wall-wart style charger from a pretty reputable brand that I would expect to work. Also almost certainly smaller and more portable than the official one.

Response by poster: Ended up getting that Anker one linked by BungaDunga. It's a bit heavier than expected but much preferred over the one that came with the laptop. Also, although the Anker website says black ones won't ship until Sept 20-30, 2024, I was able to order one on Amazon and get it next day on Sept. 15. Already field tested and works well with my laptop.
