I recently picked up these 2. One from:

Amazon- https://www.amazon.com/gp/product/B08586CVVV/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1

and one from

Ebay- https://www.ebay.com/itm/3in1-Qi-Wireless-Fast-Charger-For-Samsung-Galaxy-Note-20-Ultra-S20-S10-Watch-Bud/324218009896?ssPageName=STRK%3AMEBIDX%3AIT&var=513280234115&_trksid=p2057872.m2749.l2649

​

Both work fine. The Mophie from Amazon has a open USB slot to plug in any watch charging dock or cable. And the one from ebay has a dedicated watch compatible dock for samsung watches. The only cons are the both will only charge the phone at a max 10w instead of 15w
