I have a question about one of these claims. It says "Once your device has charged, the intelligent circuitry enters standby mode to avoid overheating and overcharging. "
This claim has nothing at all to do with this charger right? All Qi chargers behave the same in this regard because it is built into the spec right?
Per wikipedia article for Qi charging standard: "Regulation of the output voltage is provided by a digital control loop where the power receiver communicates with the power transmitter and requests more or less power. Communication is unidirectional from the power receiver to the power transmitter via backscatter modulation."
So there really is no "intelligent circuitry" in this qi charger, correct? The intelligence comes from the power receiver, which in this case is typically a phone. I notice the sentence from the product description is cunningly ambiguous in which device actually possesses the "intelligent circuitry."
So spending a few extra bucks on this device gets us no additional benefits (over a cheaper qi charger) in terms of avoiding overcharging/overheating on our device, correct?
Note I am not necessarily saying this device is not worth the money; I hope it is built to tighter tolerances than the cheaper versions which would maybe justify a price increase (but I don't know and their marketers failed to sell me).

gnomedWhat you raise is right and I can simply answer why they say "intelligent circuit" its marketing.. You can say the same thing with smartphones. In no way it is smart, its doing what it is told to, but people want things that are said to be smart. That's the way I can put it.
