And the actual TEG chips do produce electricity? Or if that is not correct, what is the difference? I'm having a difficult time finding info on the different models.
For lack of finding an informative site, I'm mostly relying on web reviews and specs for available products. It's a bit tedious!
And if they ARE truly different, how does one weed out a true TEG from a peltier model? Just about every product I find online looks identical with little or no info about the differences/specs, even when one is 3-5x the price.
