What makes Fusion Power better than MACH3 is 8 years of shaving innovation. Gillette Fusion Power is an advanced shaving system with technology on the front and back. It shares the same core cartridge technology as Gillette Fusion: the 5 Blade Shaving Surface Technology, the Precision Trimmer Blade, the Flexible Comfort Guard, and the Indicator Lubrastrip. Gillette Fusion Power contains a blade coating that reduces the cutting force over Fusion Manual, providing incredible glide and comfort while shaving. In addition, Fusion features an enhanced lubricating indicator strip that fades to white when you may no longer be getting an optimal shave. Gillette Fusion Power contains a Microchip inside the razor handle. The Microchip creates an entirely different platform of technology that helps drive the system's performance.

Compared to M3Power Gillette Fusion Power contains significant enhancements to both the inside and outside of the razor handle. On the inside: Unlike M3Power, the Gillette Fusion Power handle contains a microchip. The microchip enables three primary functions: the Voltage Controller, the Low Battery Indicator Light and the Automatic Shut-Off feature. On the outside: The on/off button on the Fusion Power handle has been optimized. The button is flush with the razor's surface and is positioned lower on the handle. This enhanced design helps prevent accidental activation or deactivation while shaving. The handle also contains more elastomer than M3Power. The elastomer extends around the entire razor handle, giving users a more secure grip for enhanced comfort and control.

A battery-powered razor delivers an optimal shave when the voltage and frequency remain consistent shave after shave. Over the lifetime of the battery, the voltage can weaken, reducing frequency and therefore performance. The Microchip in Gillette Fusion Power maintains constant voltage and frequency over the lifetime of the battery, delivering consistent product performance every time you shave.

When a battery reaches a certain level, the oscillation frequency declines and the system is no longer capable of delivering the optimal shave. The Microchip inside Gillette Fusion Power senses when the battery is approaching this level. When this happens, the Low Battery Indicator Light begins to flash, signaling that it's time to change the AAA battery.

The Automatic Shut-Off feature turns the razor off after roughly 8 minutes of continuous operation. This feature protects the battery if Fusion Power razor is accidentally activated, especially when traveling.

With the introduction of battery-powered razors, Gillette has opened a new chapter in wet shaving. The addition of oscillation to Gillette wet shaving systems has been shown to deliver a "boost" in shaving performance through the soothing micropulses that lead to great comfort.

The Precision Trimmer Blade can be used with the power turned on or off. Preference varies from person to person. Using the Precision Trimmer Blade with or without power is an individual choice.

Similar to M3POWER, Gillette Fusion Power utilizes an AAA battery. With the Low Battery Indicator Light, Gillette Fusion Power will let you know when it's time to change the battery. Assuming average shaving, the battery should last approximately 3—6 months.

Yes. Gillette Fusion Power is watertight and totally safe to use in wet environments.
