Will this work for a Samsung a10? As well as older Samsung phones?

I can't say for sure if this'll work for the A10, but I doubt it'll work with older Samsung models. I think it was the S9 that I had before moving to the A71, and no, it doesn't support this size of card; 256gb max. Best thing to do, is do a search on the models you want to specifications for. Such as.... What size card does a Samsung A10 support. That's what I did for my A71 and found 512gb was the max it supported. I can't say for sure, but you may still be able to use a larger card than what they say the phone supports. Using a PC/Laptop, you have to format the card into smaller partitions. Where you end with smaller drives instead of one large one. I'm just not positive if Androids; any phone's operating system for that matter; can distinguish a multi-partitioned drive. Got the feeling they can't, it just depends on how they coded the operating system.

Would this SD card work for a Moto G Power (2021) phone?

Hello, Yes, the Moto G Power (2021) is compatible with microSD cards up to 512GB. ~Samsung Pro

Can I still return these after 30 days?

You will need to refer to the seller's terms as they will vary. It will also depend upon the condition and reasons for the return.
