Hello,
I am trying to determine the common differences I can observe in a side by side comparison at the circuit board level of a UL certified AC/DC wall adapter and a physically identical model that is lower cost and non-UL certified.
For a specific hypothetical example if I were to disassemble side by side a 5v DC 2-Amp UL-Certified Adapter that company A sells for $10 next to a externally identical 5v DC 2-amp NON-UL certified adapter that Company A sells for $5, what type of differences might I see? Are their specific component quality requirements that must be in a UL certified device of this type to look for? Higher gauge wire possibly? Additional protection circuitry?
Any suggestions are appreciated.
