If a switched mode power supply module producing 19 volts DC is a transformer then connecting a lap top to any transformer producing 19 volt would be safe and the lap top would be correctly powered.
Please stop trying to insult our intelligence by dropping the word "electronic" in an attempt to resurrect your doomed argument against the term "electronic transformer" by pretending that things like this are called transformers.
They are not - they are called "
electronic transformers". If you actually take the trouble to look you will see the truth of that.
Ah that doesn't seem right. Yes it isn't right, the SMPS used to supply a lap top is not refered to as a transformer nor is it refered to as an electronic transformer.
Nor is this:
But this is though:
Did you have a useful point to make?
Or have you decided to try a new way to insult everybody here by expecting them to believe that because
some power supplies are not called electronic transformers
none of them must be?
Seems peope who have been involved in designing lap tops are better informed about transformers than those people profiting from marketing lighting equipment to the general and generally ignorant public.
No, it seems that they have given their products a different name.
But...
Oh dear.
What are we to do now?
And also, since you've brought the topic up again, will you please explain how "
people profiting from marketing lighting equipment to the general and generally ignorant public" are assisted in running their legitimate businesses making and selling products which people need by calling them "electronic transformers" whereas they would be hampered if they called them "power supplies".
I guess you could try your Plan B, which is to ignore that sort of question, and to blithely continue expecting us to believe that the
name does affect what is inside, or does affect the nature of the device, or does allow makers to sell items to the public which they could not do if they used a different name of which you approved. You've been doing that all along, so I guess you must think it's working.
Go on BAS prove your point and connect your laptop to a transformer instead of its power supply module.. Any transformer of the correct voltage will do if you are correct in your opinion.
Please stop trying to insult our intelligence by dropping the word "electronic" in an attempt to resurrect your doomed argument against the term "electronic transformer".
