The real reason for the Power is that Gillette owns Duracell.
And the response from P & G:Dear Rob-The differences between the Power and Manual Fusion Cartridges are subtle but there are differences. The Power Fusion Cartridges have aloe, vitamin E and natural oils in the lubrastrip while the Manual Cartridges have just aloe and vitamin E. There is also a slightly different coating on the blade of the Power Cartridges. That coating was designed to work with the vibration of the razor. I hope this answers your questions.Thanks again for writing.Kelly HFusion Team
