In my opinion, as a consumer, this is up to you. If you need this, get a UPS battery backup (or a laptop which has its own battery). Or, you can get a super specialized SSD. Ultimately though, most consumer SSDs DON’T need this feature. And if they did include it by default, it would likely be environmentally questionable for a feature most people will never use (because most consumer SSDs these days go into laptops with their own batteries).
You didn't understand the issue. It's not that these drives lose data with sudden power loss. It's that you tell the drive "please write all data that is currently in your write cache to persistent storage now" and then the drive says "ok I'm all done, your data is safe" and then when you cut power AFTER this, your data is still sometimes gone. This has nothing to do with any batteries, or complicated technology. It just means make your drive not lie.
