What are the disadvantages of rechargeable hair clippers?

To put it simply, the biggest problem is battery and power.

Low-end rechargeable hair clippers use nickel-cadmium batteries. Nickel-cadmium batteries are economical and durable but have a memory effect. Battery capacity is reduced by one point after one charge.

At present, most household hair clippers used nickel-cadmium batteries have a capacity of less than 800 mA, and the life of batteries in hair salons does not exceed one year .

At the same time, nickel-cadmium is toxic and not environmentally friendly.

Mid-range rechargeable hair clippers use nickel-metal hydride batteries. The power reserve of nickel-metal hydride batteries is 30% higher than that of rechargeable hair clippers produced by conventional factories. Ni-MH batteries with a capacity of 1200 mA or more and nopollution for the environment. However, nickel-metal hydride batteries have a high self-discharge effect, about 30% or more per month, so they should be charged before each use if they are not used frequently.

Rechargeable electric lawn mowers of global brands such as Wall of the United States, Moser of Germany and Panasonic of Japan have generally adopted lithium batteries for a long time, due to the decline of the market. Production cost of lithium batteries. Many rechargeable electric hair clippers in China have gradually begun to be used. At present, rechargeable electric hair clippers using lithium batteries are the best.

But even the best professional rechargeable hair clippers have a battery life of no more than 5 years.

In terms of power, due to battery capacity and limitationscost, the higher the power, the shorter the use time, so the power of rechargeable hair clippers is generally less than 5W

. p>Some babies The power of the hair clipper is even less than 3W, so it is easy to have uneven shaving and haircut.

General plug-in and corded electric hair clippers have a power of more than 6W, simple structure and long service life for home users who do not have frequent haircuts

p>

Corded hair clippers. are a better choice.

No

The charger specifications of different models may be different, for example the current output of the charger is different. The standard charging current and voltage of the charger can ensure better charging efficiency. For example, a charger with low charging current will extend the charging time orwill fail to charge if it exceeds the maximum, it may break the electronic components. It doesn't matter if the voltage and current of both chargers are the same. So the 3.8V battery you mentioned cannot be charged with a 5V charger.
