What happens if you charge your phone directly with 220V?

The mobile phone cannot withstand the voltage of 220V, and it will be damaged immediately. and even cause **. Don't test, just think about it.

The little board chip of the phone will burn out, and then there will be no then, the battery and the like will be fine, because the current will not arrive.

The charger of the mobile phone has a voltage conversion function, if you directly charge the mobile phone with a voltage of 220 volts. The phone just broke down, you can't do that.

It's definitely not good, now the charging voltage of the mobile phone is only how much, directly 220, if you are lucky, you will burn the phone directly, and if you are unlucky, you will see it in minutes. Don't do such dangerous experiments, just think about it, because you won't cross over.

Friends all know that when charging a mobile phone, you need the support of the mobile phone's charger. A mobile phone charger provides a stable working voltage and sufficient current through a regulated power supply to convert household electricity into the amount of power needed by the mobile phone. But what happens if you charge your phone directly with AC?

This is definitely unreasonable, it will burn the phone.

It may happen ** naturally, the cell phone battery voltage.

It cannot be charged directly, and the rated voltage is 4V

When using the mobile phone, it is not possible to charge the mobile phone, and the corresponding operation mode recognition system must be carried out.

What happens if you charge your phone directly with 220V? It's okay.

If the charger with better performance can work at full load in the full voltage range (AC85 AC260), so if the charger ***, it will not have much effect.

At the same time, when working at a lower voltage, the switching power supply inside the charger is under greater pressure, so it may affect the life of the charger. It depends on the performance of your charger, if the charger with better performance can work at full load in the full voltage range (AC85 AC260), so if the charger ***, it will not have much impact, at the same time, when working at a lower voltage, the switching power supply pressure inside the charger is larger, so it may affect the life of the charger! However, I personally don't think the average user can feel the difference!

If you charge the phone directly with 220 voltage, it will burn out the power cord and the phone, which is absolutely not okay.

The 12V battery has a dedicated voltage regulator that is stabilized to 5V to charge the mobile phone.

1. If it is 12V of a single battery and there is no cigarette lighter seat, the wire can be directly welded to the voltage regulator. Pay attention to distinguish between the positive and negative poles of the first wax.

2. If you use a 48V, 60V, 72V or even higher battery pack, you can directly connect the 220V charger of the mobile phone to the power supply of the battery pack, because the mobile phone charger is a travel charger with a wide voltage, which can work under the voltage of the battery pack, and does not distinguish between positive and negative poles.

3. If you use a 48V, 60V, 72V or even higher battery pack, you can directly connect the mobile phone 220V charger to the battery pack power supply, because the number of rounds is that the mobile phone charger is a wide voltage travel charger, which can work under the voltage of the battery pack, and does not distinguish between positive and negative poles.

OK. It depends on how low your voltage is.

Find your phone charger:

Distinguish the front and back of the charger plug:

Look at the side parameters of the charger head:

100-240V is OK, plug in the mobile phone interface and you can charge.

There is a voltage range on the charger, and many chargers can work at 110v 220v. Take a closer look.

It should be possible, the general input of the mobile phone charger is 100-240V AC power, as long as the city voltage is in this range (the normal city voltage is 220V), the mobile phone charger can work normally and output 5V constant DC power to charge the mobile phone.

It's okay, it's safe, and it doesn't affect your phone much.

From P=U*i, it can be seen that when the battery level is constant, P can be regarded as V charging, and there are the following feasible ways to shorten the charging time:

I raise u. by all means

u by all means and raise i

Both i and you were improved.

The mobile phone chargers sold and used in China all support the input voltage of AC 220V, because the power supply voltage of residents in China is AC 220V 50Hz.

However, it does not mean that the mobile phone charger only supports the power supply voltage of 220V, please pay attention to the rated input voltage marked on the charger, as long as the input voltage is within the range of the nominal value, it can be used. For example, the charger in the figure below, the nominal input voltage is AC100 240V 50 60Hz, which shows that it can be used between AC 100 and 240V, which is basically compatible with the power supply standards of all countries in the world.

There is no doubt that the plug part is 220V, 220V has been rectified, isolated, and adjusted to get the 5V we want, not that you said that 5V is not felt, but AC is isolated by the transformer, and there is no circuit with the earth, so I don't feel the electricity, if there is no transformer isolation, 1V can electrify you.

The AC input mobile phone charger cannot be plugged directly into the DC power supply because:

The charger does not support it, and the mobile phone charger requires AC power input and does not support DC input;

Plugging directly into a DC power supply will damage the charger;

Theoretically, the mobile phone charger can use DC input, but because the mains power is generally AC power, the mobile phone charger is basically AC input.

The input of the mobile phone charger cannot use pure direct current, and must contain direct current with pulsating AC components, otherwise it cannot be charged into the mobile phone.

Not necessarily.

If it's a transformer-style charger (old-fashioned mobile phone charger), then no. AC input must be used, otherwise it will burn out or even be dangerous.

If it is a switching power supply, yes. But the DC used must be within the allowable range of the mobile phone charger, if the charger is AC220V input, then the input DC needs to be around 310V. If it is AC100 220V, then the input DC needs to be 142V-310V.

The above voltage values are only considered nominal values, and the actual situation of the voltage range that may be supported may vary slightly.

The above are just emergency alternatives in exceptional circumstances. Danger may occur in some cases.

It is highly recommended to use alternating current with nominal input parameters.

This one doesn't work.

220V is alternating current, the charger itself comes with a transformer rectifier, and the AC 220V must be turned into direct current to charge the mobile phone. Only AC transformer, which is more convenient and easy.

12V, 24V, is direct current, and is much higher than the mobile phone charging current, even if it is directly connected to the mobile phone for charging, the mobile phone is basically burned immediately.

With this kind of device, you can use the car cigarette lighter to charge the mobile phone, but you need to transform the voltage to the mobile phone can be charged. If you have this demand, you can buy one, which is not expensive. As illustrated

No, 12V DC is not possible, this 220V input charger wants to work in the car requires an inverter 12V24V inverter 220V AC.

No! The charger is a switching power supply, according to the input 220 volt AC design, connected to the DC power supply of V, the charger can not work normally. The mobile phone battery is generally volt, the output voltage of the charger is 5 volts, directly connected to the 24 or 12 volt power supply, the charging current will be very large, the mobile phone battery in this large charging current, there is a great danger!

Yes, buy an inverter, depending on what kind of electrical appliances you use, how many watts are available, 500w can already meet your requirements,

Yes, the mobile phone has a transformer rectifier, which is the big plug, not the 220V voltage direct mobile phone, and it must be burned out directly. And the phone is definitely DC charging. Of course, the safest thing is to see whether the output voltage value on the original transformer of the mobile phone is consistent.

I really can't see that I can ask someone to help you see it, if you don't even have someone to help, you can quickly plug and unplug the experiment, but fast plugging and unplugging is not too safe.

It should be possible to have a transformer.

Summary. Hello pro, the charger to charge the mobile phone, the charger that calculates the home voltage, and the charger to charge the mobile phone belongs to the parallel circuit, and the voltage is equal everywhere.

Hello pro, the charger to charge the mobile phone, the charger that calculates the home voltage, and the charger to charge the mobile phone belongs to the parallel circuit, and the voltage is equal everywhere.

A charger is a tool used to charge electronic devices. There are many chargers, such as lead-acid battery chargers, VRLA battery testing and monitoring, nickel-cadmium battery chargers, nickel-metal hydride battery chargers, lithium-ion battery chargers, portable electronic devices lithium-ion battery charging finger benders, lithium-ion battery protection circuit chargers, electric vehicle battery chargers, car chargers, etc. Proper charging is good for prolonging battery life, while proper charging will have a big impact on battery life.

Lithium batteries are basically packaged separately according to the number of products, and they are not common to each other, so each product also provides its own charging equipment, which is not universal to each other, and can be used as long as it follows its own instructions when using.

What is the voltage of the home circuit, the normal land stove is 220 volts, the voltage of household electricity varies from country to country, our country usually is 220 volts, 50 Hz, generally single-phase alternating current, the safety voltage of the permanent branch slippage is not more than 36 volts, the actual use can not be enough to contact with the live wire or the conductor connected to the live wire, otherwise there will be an electric shock accident, can not ensure the personal safety of the owner.

Look at the specifications on the nameplate of your charger, generally the input voltage has a range, and the current mobile phone charger is generally a wide range of input, supporting global voltage, 110V to 240V input can be.

The power output should be the same as that required by the mobile phone to be charged.

Does it make a difference to charge my phone with a power supply higher than 220V? Let's start with a simple pure resistance.

1.What is the passing current of a 5 resistor connected to a 5V 500mA power supply?

2.What is the passing current of a 5 resistor connected to a 5V 1000mA power supply?

3.What is the passing current of a 5 resistor connected to a 5V 5000mA power supply?

4.What is the current of a 5 resistor connected to an ideal 5V constant voltage source?

1.5V 5 = 1000mA, but the actual output can only reach 500mA, then the voltage will be pulled down after connecting this load.

2,3,4.The current will be stabilized at 1000mA output.

For example, my light is 220V 3W, which is a rated input of 220V. The output capacity of my home circuit is about 220V 30000MA, will the bulb burn?

The same is true for mobile phones, the output current of the power supply is only the output capacity, when this ability is greater than what your mobile phone needs, it will work at the current required by your mobile phone to charge. If it's less than your phone needs, it will be charged at the maximum capacity of the charger.

Of course, it is not excluded that some strange products in the world can only work in an undervoltage state, and the standard voltage is easy to burn. This is rare.

You can use a power supply higher than 220V to charge your phone, the power supply voltage cannot be higher than 240V, charging your phone below 240V will not have an effect, and higher than 240V will damage the charger and the phone.
