Tips For Purchasing Electric Shavers

There are many types of electric shavers, and their rated voltages, rated powers, transmission mechanisms, structural principles, prices, etc. are all very different. When purchasing, you should adapt to local conditions and according to each person's financial situation and specific requirements, and refer to the following points:
1. If there is no AC power source, or if you often carry the user out, it is generally better to choose an electric shaver powered by dry batteries.
2. If you have an AC power supply and are often used in a fixed place, it is best to choose an AC power supply or rechargeable electric shaver.
3. If you want to be able to use it in various situations, you should choose a multi-purpose electric shaver with AC, rechargeable or dry battery type.
4. If your beard is sparse and thin, your skin is smooth and you want a shorter shave, you can choose a vibrating reciprocating electric shaver or a general rotary electric shaver. For those with thick and stiff beards, you can choose a rectangular slit-type external blade electric shaver, a circular slit-type external blade electric shaver, or a three-head rotary electric shaver. However, this type of electric shaver has a complex structure and is relatively expensive.
5. The battery used in the rechargeable electric shaver is preferably a cylindrical sealed nickel-copper battery, which is required to be easy to charge, safe, reliable and have a long service life. The dry batteries used in dry-cell electric shavers are preferably alkaline-manganese batteries or manganese dry batteries, and they require easy battery replacement, good contact, and long service life.
6. When in use, there should be no obvious vibration and the movement should be brisk.
7. The shape is beautiful and light, with complete parts and good assembly. The assembly and disassembly of accessories are convenient and reliable.
8. The blade of an electric shaver should be sharp. The sharpness is generally judged by human feeling. The main reason is that it is painless to the skin, cuts safely, and has no irritation. The remaining beard hair after shaving is short and there is no obvious feeling when wiping it with your hands. The outer knife can slide smoothly and smoothly on the skin.
9. It is easy to clean after use. Hair, dander, etc. should not easily enter the electric shaver.
10. It should be equipped with a cover to store and protect the blade, or have a structure that allows the blade or the entire blade to be retracted.
11. The insulation performance is good, safe and reliable, and there should be no leakage.
12. The sound of the electric shaver running without load should be small, uniform and stable, and there should be no fluctuating noise.
