For those of you who are like me and still enjoy vintage tech for their simplicity and their deconnectivity, it can be a hassle to keep up with newer devices. One of those things is the 30-pin connector. You know, the once powered by FireWire and later by USB(-A). The cable that was THE cable before the Lightning cable. Well that one can now be found for USB-C.
In the US you can grab some via Amazon: https://www.amazon.com/dp/B09L5YBCGK?th=1
My EU friends will have luck on eBay: https://www.ebay.co.uk/itm/134744966601
