But what he doesn't say is that Apple's charger is safer than the standard design. The best we can say for Apple is that it has cleaner power which is helpful for the touchscreen circuitry. That's why I say Samsung's charger compares favorably: it charges the device and it meets UL standards.
You said that it compares favourably and then noted that it's 1/3 the price. To my eyes that reads, "the Samsung charger is a better value", and I think that that's what you meant too, until Terreta corrected you.
