Comparison Vitek VT-2568 vs Scarlett SC-HC63C56

The cutting height is influenced by the type of cutting element and the inclusion of detachable combs. Toothed blades can trim hair as short as 1 mm. By coupling a toothed blade with a detachable comb, the cutting height can range from 2-3 to 20, and even 30 mm – the precise height hinges on the provided comb attachments. There are defined minimum and maximum cutting heights. The minimum pertains to the blade's inherent capabilities, devoid of attachments. The maximum cutting height is determined by the detachable comb type.

The number of haircut length options provided in the design of the clipper or the design of the nozzle. The more such options, the more versatile the clipper and the more cutting options it provides.

The performance of the tool, the maximum rotation speed of the motor and how well the device handles with thick and coarse hair depends on the power of the electric motor. So, for cutting thick head hair, you need a clipper with a power of at least 15 W, the performance of such a device is usually enough to ensure a motor rotation speed of 10,000 rpm. But there are also more powerful clippers(from 20 W). Trimmers for beards and mustaches usually need 5 W of power. Such models most often have a performance of 3,000 – 5,000 rpm.

— Li-Ion. Lithium-ion (Li-Ion) batteries currently dominate the market due to their high energy density, compact size, and light weight. On average, Li-Ion batteries last for approximately 400 charge-discharge cycles. They exhibit minimal self-discharge and lack a prominent "memory effect" (capacity decrease when charging a partially discharged battery). However, these batteries are sensitive to cold temperatures and require precise charging current conditions.

— Li-pol. Lithium-polymer (Li-Pol) batteries maintain stable output voltage even during significant discharge. On average, Li-Pol batteries offer a lifespan of around 800 charge-discharge cycles. These batteries don't exhibit the memory effect and remain stable across a broad temperature range, from -20 to +40 degrees Celsius. Their drawbacks primarily involve vulnerability to deep discharge and overcharging. This highlights the necessity for specialized chargers that employ optimal power delivery methods tailored to the lithium polymer context.

— Ni-Cd. Nickel-cadmium (Ni-Cd) batteries are engineered to handle substantial charge and discharge rates. They can be stored either charged or discharged without issue. These batteries aren't impacted by heat and maintain their capacity in cold conditions. However, the primary drawback is the "memory effect," which emerges when the battery is prematurel...y charged with residual capacity. Despite being outdated, Ni-Cd batteries are occasionally employed in clippers.

— Ni-Mh. Nickel-metal hydride (Ni-MH) batteries excel at managing substantial charge and discharge rates, making them suitable for demanding electric motors and facilitating quick charging. Contemporary Ni-MH batteries offer a prolonged lifespan of up to 1000-1500 charge-discharge cycles, while being environmentally friendly. In comparison to Li-Ion batteries, they appear bulkier and add weight to the device, yet they come at a more affordable cost. This battery type has replaced the previously mentioned nickel-cadmium technology.

— LiCo. Lithium-cobalt (Li-Co) batteries are renowned for their impressive energy storage within a small and lightweight structure. These batteries exhibit minimal self-discharge and lack the "memory effect". They maintain voltage stability almost until complete discharge. However, Li-Co batteries aren't engineered to handle substantial charge and discharge rates.

The typical duration of uninterrupted operation for a clipper powered by a self-contained source (battery or rechargeable batteries, refer to Power Source) without requiring a recharge or battery replacement. Extended continuous operation time becomes particularly crucial when intending to use the clipper in locations where recharging or battery changes are unavailable, such as during long trips.

— Scissors. The inclusion of a set of scissors with the hair clipper enhances its value, catering to both experienced enthusiasts and professional hairdressers. This bundled option provides a comprehensive haircutting package, and the scissors serve as a valuable tool for addressing finer details that the clipper may not handle alone.

— Comb. Availability in a set of delivery of the clipper of a comb. A comb is one of the most necessary tools for a hairdresser, so when purchasing it together with a typewriter, the user gets rid of the need for a separate purchase.

— Charging stand. The stand serves a dual purpose as a charger and storage unit for the machine. It facilitates convenient recharging during quick intervals between cutting sessions, making it ideal for hairdressers to keep the machine on the stand while using scissors or other tools. Additionally, it can double as an accessory stand (see Stand for accessories).

— Stand for accessories.The stand is designed to store clipper accessories such as detachable nozzles, cleaning brushes, and oilers. Using this dedicated stand reduces the chances of losing any of these accessories. In cordless clippers, this role is frequently fulfilled by the charging stand, which also serves as a storage solution (refer to Charging Stand).

— Case. Cases include all kinds of rigid structures for storing the clipper. 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 low-cost clippers, a much more primitive fabric cover is included in the package.
