SANDISK 1TB Ultra microSDXC UHS-I Memory Card with Adapter - Up to 150MB/s, C10, U1, Full HD, A1, MicroSD Card - SDSQUAC-1T00-GN6MA

Hi again - is there a particular reason to use the wall adapter you recommended, or can I use any of the Anker ones I have for my other devices? Also, I got this SanDisk microSD card from Amazon: https://www.amazon.com/dp/B0B7NYN3N3?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 But the RGC setup video said to get a high-performance card or something like that. Will the one I got work fine? Costco also has a Lexar PLAY PRO 1 TB microSDXC Express Card for $179.99. Is that a better choice? https://www.costco.com/p/-/lexar-play-pro-1-tb-microsdxc-express-card/4000399472?langId=-1 Also, what’s the story with compressing some ROMs? What I’ve read about it is kind of confusing.
