What are the cheapest things you can use to add more storage? I've used up all the internal storage pretty quickly with apps and need more storage to install more apps.
I don't want to spend more or as much to get additional storage as I did for the Chromecast itself.
usb hub and any sort of storage you want to plug into that.
This hub works with the stock power supply. The ethernet is slower than wireless, but it works if you need it. https://www.amazon.com/gp/product/B085XZGVN5/
I use this 256gb thumb drive (got on sale), but there are probably cheaper options available https://www.amazon.com/dp/B07D7Q41PM/
Note you will be limited to fat32 because... google
Buy a atoll USB C hub - amazon £15 And a USB 3 memory stick will work with the chromecast power supply with no issues
