Comparison Philips Series 7000 MG7785 vs Philips MG7770

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.

— Self- sharpening blades. Blades made using a special technology, thanks to which they sharpen themselves, due to friction against each other in the process. Thus, the blades remain sharp at all times, and their maintenance is limited to the replacement of worn blades.

— Function of thinning. Thinning in hairdressing is called cutting the ends of the hair at different levels — as a result, after the haircut, the hairstyle looks more natural and magnificent. In machines, special thinning nozzles are usually used for this.

— Wet cleaning. The clipper's capacity for wet cleaning of its attachments, allowing them to be rinsed under flowing water, is a notable feature. It's important to clarify that this pertains exclusively to the attachments – not all models with wet cleaning have waterproof casings (see below). Nevertheless, even without a waterproof casing, it might still be feasible to clean the attachments without detaching them from the device. In general, wet cleaning is frequently more efficient, quicker, and precise compared to dry cleaning.

— Waterproof body.In this context, a sealed enclosure is indicated, enabling the machine to withstand water exposure without adverse effects. The extent of protection can vary; certain models tolerate brief water immersion, while others can operate even when submerged. These specifics should be detai...led in the accompanying instructions. Nevertheless, for clippers used in environments with elevated humidity (like bathrooms or wet areas), having such a water-resistant enclosure is greatly preferred, and sometimes obligatory.

— Built-in vacuum cleaner. The clipper is equipped with a vacuum cleaner, which greatly facilitates cleaning after cutting. The suction hole located under the blades sucks most of the cut hair into a separate reservoir. Of course, there will not be a 100% return, but there will be much less hair scattered on the floor. However, when cutting a beard, a vacuum cleaner will do just fine.

— Laser pointer. The presence in the electric razor of a laser in the form of a straight line. With its help, you can easily, and most importantly, evenly and symmetrically trim the desired areas.

— 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.
