Thanks for the message. Yes, there are good Black Friday UPS deals right now. For a DS218 you only need a small line interactive unit and there are several discounted models worth considering. Have a look here: https://amzn.to/4pskFfh and check the PowerWalker and APC options in particular. Both brands work well with Synology and will give your NAS enough time to shut down cleanly during short power cuts. Let me know if you want help choosing the exact VA rating.
