Gillette makes power razors that have the same core elements as a manual razor, but will vibrate when turned on. The [power razors require a AAA battery](/en-in/battery-usage) and can be activated by pushing the power button on the handle. The power razor will automatically shut off after 8 minutes, but can be turned on again. All power razors are Shower-safe. Additionally, all power razor cartridges are interchangeable with their base manual cartridge, and in the case of the [Fusion family of razors](/en-in/products/fusion-razors) (Fusion, ProGlide, and Styler), all Fusion cartridges will fit all Fusion handles.
