I have this power supply - https://www.amazon.com/gp/product/B0BBYSZ2PV/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 and this hub on my devices and it works perfectly. https://www.amazon.com/gp/product/B093FKT9BF/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 There are other hubs that work, but I've liked these the best. I had a tube style Shield but unfortunately it died on me. I've found the CCWGTV devices work perfectly for what I need..
