Comparison Panasonic ER-GP80 vs Panasonic ER-1512

Universal guide comb is an adjustable-height comb attachment that lets you make haircuts with smooth transitions without needing to swap attachments. You can change the comb height on the fly by simply releasing the latch and sliding the comb. Height-adjustable combs are great because you can cut with a single attachment, which also helps keep your workspace tidy. Naturally, this type of attachment has a complex design. The comb itself can be moved relative to the base that’s rigidly fixed to the blade, and to lock the comb in the desired position, you just press the latch. Due to the complex design, the attachment’s reliability is reduced, which is why manufacturers may include several universal guide combs in the set.

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 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.

Adjusting the length of the blade allows you to change the cutting length of the cutting unit. Accordingly, this parameter affects both the trimming length and a more accurate haircut using attachments.

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.

The speed of rotation of the motor of the clipper. The speed of movement of the blades directly depends on this parameter, and the quality of the haircut, in turn, depends on it: the faster the blades move, the faster and more accurately the clipper cuts.

— 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 charge level indicator allows you to know the status of the battery, its degree of charge. Achieved using the built-in display or LEDs.
