Hello Mr.Daren Bieniek,
The STWC070LT-01 and STWC050LT-01 you purchased are both low voltage powered products and can only use 5V power.
Our manual is using the I series as an example.
Please don’t use 12V power supply, it will burn the screen directly.
You can use 5v power supply and there will be no problem.
And for more detailed information our technical staff has replied to your email please check.
