I found OOOUSE USB-C charging cables (for iPhone) but not a confirmed 20W power adapter / wall charger under that exact brand.

There is a listing: “OOOUSE For iPhone 15 Charger Block 2 Pack 20W Dual Port”. jadian.in But since it's from a less-known retailer, it's hard to verify quality and safety.

There are also OOOUSE USB-C to Lightning cables rated up to 20W, but that’s just the cable, not the brick. kmart.com
Conclusion: It’s unclear / uncertain whether there is a well-made 20W “OOOUSE” charger brick. It might be a copy / cheap third-party item, or the listing might confuse the brand name. Use caution if ordering — check reviews, seller rating, and return policy.
