Comparison BaByliss BG120E vs Philips Series 3000 BG3010

Clippers and trimmers are often equipped with fixed-height removable combs. The more combs in the kit, the smoother transitions the device can make. The standard set usually includes 3-5 combs, more advanced models may have 7-10 combs of a fixed height in a set.

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 width of the operating tool (blade) of the clipper. A wide blade is important for head hair trimmers, as it allows you to capture more hair in one pass and cuts faster. In turn, beard and mustache clippers use narrower knives, which is useful for fine work to give facial hair the desired shape.

— 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.

The weight of the clipper/trimmer is especially important when the device is planned to be used often and for a long time. The less the clipper/trimmer weighs, the less the user's hand will get tired. Of course, there is a direct relationship between the mass of the device and its performance. Powerful clippers/trimmers use a larger and heavier motor. Additionally, the weight of the device increases due to the presence of a battery pack.
