I think there are similar products with micro USB. With those Amazon links, I just wanted to point out that the trick is to just shoot for a round-looking capacity number in mAh and go from there.

Lightning, USB-C, and Micro-USB with this one here: https://www.amazon.com/ChargeCard-Prtable-Charger-Power-Bank/dp/B096YLDN3C/

USB-C to "anything else" adapters might exist - I found one on a quick search and I also own one that's USB-C to Thinkpad. The issue is that USB-C connectors are a little smarter and therefore a cheapo adapter might not work reliably, you'd need to spend a little more (like $10-20) for something that works.
