Waterproof
Models feature waterproof casing with varying levels of protection, often indicated by two numbers. The first number pertains to dust resistance and is often marked as X. The second number reflects moisture resistance, particularly water. For instance, IPX3 and IPX4 offer splash protection, IPX5 and IPX6 enable shower use, while
electric shavers with IPX7 can be submerged underwater for up to 30 minutes.
Number of cuts
The number of cutting movements made by shaver blades per minute. Determines the number of hairs that the device can cut in a given amount of time. The higher the number of cuts, the more efficient and faster the shaving process.
Charge level indicator
The presence in the design of the electric shaver
charge level indicator.
It's important to highlight that in this context, an indicator refers specifically to a visual representation of the charge level. This could manifest as a battery icon or a percentage displayed on the
display. Such an indicator significantly simplifies battery monitoring, minimizing the possibility of being unexpectedly left with a depleted battery.
Voltage switching
The ability to switch the voltage for which the shaver is designed, adjusting it to the characteristics of various electrical networks. This feature is useful for those who often travel abroad: in different countries, the voltage in the outlet can also be different. For example, in Europe and most Asian countries, 230 V networks are used, but in North America the voltage is 110 V.
In the simplest models with this function, the voltage is switched manually, more advanced shavers have an automatic network adjustment system.
