How many volts is a charger for a rechargeable electric shaver?

In the previous rechargeable electric shaver, the battery inside was a volt-nickel-metal hydride battery, and the battery and charging components were built into a circuit board, so there was no need for another charger; Now some of the new electric shavers are lithium batteries, most of the lithium batteries are voltile, and the charging device is built-in and external. The external one should be 5 volts.

Attach the battery to charge, measure the voltage that should be available at both ends of the battery, and prove that the charger circuit is good. Or measure whether there is a charging current, pay attention to prevent electric shock, some circuits are not insulated from the mains.

Rechargeable shavers generally use two types of batteries, one is nickel-metal hydride batteries, most of which are volts. The other category is lithium batteries, which are mostly volts, so you have to figure it out, otherwise getting it wrong can be catastrophic.

In general, there are two kinds of power sockets on the wall in the family: 10A and 16A, and the power is calculated as follows:

The socket of 10A*220V=2200W, 16A*220V= can withstand a maximum power of 2200 watts, and 16A can withstand a maximum of 3520 watts of power, if this power is exceeded, the socket will burn out.

Extended information: 16A socket: Socket with a rated current of 16A (generally for air conditioners).

The 16A socket means that the rated value of the socket is: 250V 16A, which is suitable for appliances with a maximum rated current of 16A, that is, appliances with a maximum rated power of 3500W.

At present, in China, air conditioners generally use 250V 16A sockets, and drum washing machines, microwave ovens, electric water heaters, and induction cookers generally use 250V 10A sockets; Refrigerators, washing machines, televisions, electric cups, and computers generally use 250V 6A sockets, and the socket sizes of 6A and 10A are the same in terms of socket size, and the size of 16A sockets is different.

For the sake of waterproof performance, many small household appliances are now inductive charging...

The attribute of the electric shaver is that it can be used for n hours on a single charge, as long as the battery is not lost, it can be used for a period of time when it is fully charged, and the charging time is not sensitive (for example, my electric toothbrush imported from Germany has to be flushed all day). Unlike high-frequency charging equipment such as mobile phones, there is no need to press such a thing as a C port.

Therefore, I think that without a C port, firstly, it is unnecessary, secondly, the cost will increase, and thirdly, it will naturally affect the waterproof performance.

As for why Xiaomi is doing this, I personally think it's a pure gimmick. After all, Xiaomi is not a professional manufacturer of razors, and there is no selling point in using a ready-made solution, so add some content that looks "high".

Be sure to wait until the battery is completely out of power before charging, the first charge time is 12 hours, and the next 10 hours is fine. When I use it, I feel that the shaver is very slow, and the red light flashes that it is almost out of power.

Completely used up, the first 12 hours of rotation is out of power.

Summary. Hello kiss, shaving utensils. It is a self-serving tool and is mostly used by adult men.

Razors can be divided into three categories: safety shavers, electric shavers, and mechanical shavers according to their structure. In order to guarantee the shaving effect, it is best to choose a high-performance alkaline battery for dry electric shavers. If it is not used for a long time, the battery must be removed to avoid damage to the internal parts due to battery leakage.

Safety shaver: consists of a blade and a hoe holder. The knife holder is made of aluminum, stainless steel, copper or plastic, etc.; The blades are made of stainless steel and carbon steel, and in order to be sharp and durable, the cutting edge is mostly coated with metal or chemical coating.

To use, attach the blade to the blade holder and hold the handle of the blade holder to shave. There are two kinds of safety razor knives, one is to install a double-edged blade on the knife holder; The other is that the knife holder is equipped with two single-edged blades. When shaving with the former razor, the user needs to adjust the angle of contact between the blade edge and the beard to ensure the shaving effect.

Can shavers be charged with a phone charger.

Kiss <>

Thank you very much for your patience, I am honored to answer for you, for your inquiry: shavers are not charged with a mobile phone charger, "shavers cannot be charged with a mobile phone charger." The shaver should be charged with his dedicated charger.

If you don't use the same charger, it is easy to charge the battery and burn the circuit. The consequences of this are not worth the cost.

The voltage is the same and can be used. 5W is 5V1A, you can use 5V2000MA or 5V1000MA charging head and power bank.

A shaver will not have a battery life of two or three years, and today it is shared with a mobile phone charger for direct power supply, and the power is insufficient!

It can be charged with a 5V1000MA mobile phone charger.

Shaver charging time:

1. The charging time of different types of razors is different, but it is generally 8 to 10 hours, and there are also 1 to 5 hours;

2. The shaver used for the first three times must be charged for 14 hours to activate the battery, and each subsequent charge for about 10 hours; Richard.

3. Even if you don't use a razor, you have to charge it once a month, for 8 to 10 hours, because of the built-in lithium battery, don't charge it to the fullest;

4. The normal charging time is 8 hours, after the charging is completed, there will be a green light flashing to indicate that the battery is fully charged, after the rechargeable battery is fully charged, it is necessary to continue charging for more than one hour;

5. When the shaving branch disturbance knife is weak and the speed becomes slower and more violent, it can be charged.

It depends on the type of shaver battery.

Generally, common rechargeable batteries can be divided into two types.

1. Ni-cadmium rechargeable battery and Ni-MH rechargeable battery.

These batteries produce a phenomenon known as the "memory effect", charging in an incomplete state of discharge, which can easily overcharge the battery, which will cause crystals to grow on the electrode plate for a long time, blocking the contact between the electrolyte and the electrode plate, causing the voltage of the battery to drop, and giving the user the feeling that the battery is running out quickly.

Therefore, for both types of batteries, periodically, rather than every time, the battery is fully discharged and then recharged, which can mitigate the voltage drop caused by the above causes.

2. Li-ion battery.

Lithium-ion batteries are becoming more and more widely used because they are small enough to store a lot of energy. Lithium-ion batteries do not need to be activated by deep charging and discharging when they are first used, because the battery initialization and testing process is already completed at the time the battery is manufactured. Lithium-ion batteries also do not have the so-called "memory effect" and can be recharged at any time.

Generally, the rechargeable electric shaver you just bought needs to be fully charged for 12 hours in the first three charges, and you can charge it at any time later, but you should also be careful not to recharge it every time you use the battery, which will affect the life of the shaver.
