Comparison Philips Series 5000 S5250 vs Philips Series 5000 S5080

— Built-in trimmer. Device for trimming the contours of facial hair. A trimmer is similar to a clipper, but smaller and better suited for fine work. Located directly on the body of the device.

— Blade for hair cutting. Removable version of the trimmer (read more about the trimmer above), made in the form of a replaceable nozzle and is installed instead of the main nozzle with shaving heads. Thanks to this, the trimmer can be made wider than the built-in trimmer, and overall more efficient.

— Nozzle for ears and nose. The cylindrical nozzle of small diameter allows you to penetrate the inlet and ear and remove unwanted vegetation from there. It is installed mainly on top of the main nozzle.

— Universal comb. Such a nozzle can be useful for regular care of the stubble or beard, when you need to trim, shorten, and not just shave. Length adjustment allows you to select the desired value for a particular area or depending on the image and type of "hairstyle".

— Case. Cases include all kinds of rigid structures for storing a shaver. Cases in the form of handbags made of thick fabric also fall into this category. In addition to reliable storage of the device, they also elevate the model to the highest class. In more low-cost electric shavers, a much more primitive fabric case is included in the package.

— Charging stand. A special stand on which the shaver can be installed to charge the batteries. There are no fundamental technical differences between such charging and charging from a power cord, the main difference is that the stand can also be used to store a shaver. Therefore, shavers with a charging stand are well suited for home use.

— Wireless charging. A special stand that charges the shaver without a precise connection through the plug — just put the electric shaver on it and the battery pack will automatically start recharging. This saves the user the hassle of connecting wires and reduces wear on the connectors. On the other hand, such a function has a significant impact on the cost of the battle and increases the duration of the charging process itself, since the charging platforms themselves are made low-power for safety reasons.

— Self-cleaning station. It is a special stand where the shaver is installed for automatic maintenance. This maintena...nce, as the name suggests, primarily includes cleaning — the shaving unit is cleaned of hairs and dust - as well as charging the battery. In addition, self-cleaning systems can provide lubrication and disinfection of the shaving unit, but this function is less common and requires the use of consumables (oil and disinfectant).

— Facial brush. It is convenient to clean the face from the cut bristles with a brush. The brush that comes with an electric shaver usually has a medium bristle length. Some electric shavers are equipped with a universal brush, which is designed for both cleaning the face and combing the beard and mustache.

Type of power source used by the shaver:

— Mains. The shaver is typically powered by a household supply of 230 V, though other voltage variations are possible. When connected to this power supply, users don't need to worry about limited device operating time since the razor operates as long as there's mains voltage. This eliminates the concern of battery depletion. However, these razors rely on a power source and the cord can restrict movement. Modern models sometimes feature a hybrid system combining mains and battery power for greater flexibility.

— Battery. The shaver operates using its internal battery, offering maximum autonomy without needing an external power source. This design provides freedom of movement by eliminating the need for a mains cable. However, the battery's lifespan is finite, requiring periodic recharging. Inexpensive models lacking charge level indicators during use might pose a risk of running out of power unexpectedly, such as mid-shave, necessitating a recharge wait.

— Batteries. The shaver is powered by replaceable elements (batteries). Such devices, in their advantages and disadvantages, are in many ways similar to rechargeable ones: on the one hand, they are autonomous, on the other, the operating time is limited. The main difference is that a “dead” battery can be easily...replaced if you have spare ones with you; the built-in battery does not provide replacement, and the only option is charging, often quite long.

— From the cigarette lighter. Power supply from the car's on-board network through the cigarette lighter plug (or a separate auto socket of the same size). Shavers with this power supply can be charged and/or used directly in the car, which can be useful for those who spend a lot of time behind the wheel.

— Li-Ion. Currently, the prevailing battery type is Lithium-ion (Li-Ion), known for its high energy density, compact size, and light weight. Li-Ion batteries offer approximately 400 charge-discharge cycles on average. These batteries exhibit minimal self-discharge and lack a significant "memory effect" (capacity reduction due to charging a partially drained battery). However, they are sensitive to cold temperatures and require high-quality charging currents.

— Li-pol. Lithium-polymer (Li-Pol) batteries maintain stable output voltage even during significant discharge. These batteries offer an average lifespan of about 800 charge-discharge cycles. Unlike some battery types, Li-Pol batteries don't exhibit a memory effect, and they operate reliably within a wide temperature range of -20 to +40°C. However, they are sensitive to deep discharge and overcharging. To address this, specialized chargers employing suitable power supply algorithms for the lithium polymer context are recommended for maintenance.

— Ni-Mh. Nickel-metal hydride (Ni-MH) batteries excel in managing substantial charge and discharge currents, making them suitable for power-demanding electric motors and rapid charging. These batteries now boast impressive longevity, enduring around 1000 to 1500 charge-discharge cycles, while maintaining an eco-friendly nature. In comparison to Li-Ion, Ni-MH batteries appear bulkier and add weight to the device, yet they offer a more economical option.

The average runtime of electric shavers on a full battery charge, without recharging, is generally overestimated due to factors like hair length, density, and trimmer usage. Manufacturer claims for runtime tend to be higher than actual usage. Longer runtimes require heavier and more expensive powerful batteries. Most shavers offer around 45 minutes of runtime, while some models provide up to 1 hour or as low as 30 minutes of operation.

Charging time for the electric shaver battery from a fully discharged state to 100% charge. If freedom of movement when shaving is most important to you in a cordless shaver, and you always have access to the power supply (for example, you rarely travel), this parameter does not matter much. However, if you often travel on trips in which you have to constantly move from place to place, you should pay attention to models with a short charging time.
