Phone without charging at home. How to charge a mobile phone from batteries. iQi Mobile wireless charging
Any motorist may find himself in such conditions when the car’s battery suddenly stops working, and there is no way to charge it from a conventional charger. For example, if the car has not been used for a long time and has been parked for several months, the battery will gradually discharge and stop working. In addition, if you leave the headlights on, you simply won’t be able to start the car. In such cases, you should know how to charge the battery without using methods known to many drivers.
Determining the reason: diagnostics
If the car does not start, you should first find out exactly whether the reason lies in the battery. First you need to pay attention to the dashboard. If the indicators on it light up dimly or don’t light up at all, it means the battery is definitely dead. It’s good to have a voltmeter built into the dashboard: in this case, a sharp drop in voltage readings will indicate a problem with the battery.
It is also necessary to inspect the car battery itself. All modern batteries are equipped with a charging indicator, by the color of which you can tell whether the battery is low or not. When the indicator lights up red, that means it is so.
If the battery is dead, this will also affect the sound of the engine. The sound will be weak, more monotonous and very viscous, with a characteristic clicking sound under the hood. If any of these signs are suddenly detected, you will have to think about how to charge the car if there is no charge, showing a certain amount of ingenuity and sociability.
The “lighting” method from another car
One of the good old ways to get your car moving is to try to recharge a dead battery from the battery of another car passing by. Any seasoned motorist will tell you that if a problem arises with how to charge a battery without a charger, this is the most proven and correct way out of the situation. If a problem with the battery occurs while traveling, when it is not possible to get to the nearest technical service center on foot, other motorists will willingly and understandingly come to the rescue.
When working with batteries, keep in mind that there are many different electronic devices inside the hood of modern cars. It is important to get to the batteries without damaging them. Although, in theory, manufacturers take into account the possibility of charging one car from another, and there should be enough space for lighting. It is easy to find two terminals on the battery: positive and negative, and the positive terminal always looks larger.
In order to carry out the process of charging a dead battery from a donor car, you will need two thick wires with strong and wide clamps with a cross-sectional area of at least 10 mm 2 each. The wires must be at least 1.5 meters in length and must have a dense rubber braid, otherwise they will not withstand low temperature conditions. It is not recommended to use thinner wires, because if a strong current is applied, they may simply burn out. The current strength set before applying it must be at least 200 A.
It is best to use professional wires with wide clamps and standard colors accepted in electronics: the red wire is the “positive” pole, and the black wire is the “negative” pole. Wide clamps provide the best degree of contact, and the large cross-section of professional wires transmits current most correctly.
Once a driver is found who agrees to help, you can jointly proceed to the following actions:
- First fix the “positive” clamp on the positive terminal of the battery of the car receiving help ;
- Also fix the “positive” clamp on the positive terminal of the battery of the “donor” car. ;
- connect the negative wires strictly in the same sequence “receiver - donor”, constantly monitoring the polarity ;
- do not allow wires to touch each other ;
- start the engine of the donor car for 10-15 minutes ;
- Do not disconnect the wires throughout the entire process. ;
- start the engine of the receiving car only after 10-15 minutes have elapsed, turning off the “donor” engine first ;
- remove the clamps from the terminals without turning off the engine of the receiving car, according to the principle - “minus” from the donor, “minus” from the recipient, “plus” from the donor and “plus” from the recipient ;
- let the engine of the receiving machine run for a few more minutes until the process is fully completed .
Car pushing method
An equally old and traditional method of “boosting” the battery, allowing you to start the engine in a short time. However, at the present stage it is important to take into account that it is only suitable for cars equipped with a manual transmission.
The essence of the method: after discharge, a certain amount of energy remains in any battery, which should be enough to start the starter. You can ask people who pass by for help. When the engine starts, you should not turn it off immediately, but drive it on the road for a while in order to maximally “boost” the battery. There are also more extreme methods.
How to charge your battery in an emergency
Of course, such methods can help out when the motorist is within the city limits or on a busy highway, where the chances of meeting potential helpers are quite high. But how can you charge the battery if the driver finds himself in some remote place and the battery stops working?
In this case, there are several improvised methods for “reviving” the battery, for example:
- emergency engine start using a regular battery ;
- just shake the battery a few times .
Any regular battery can be removed from a flashlight or from a phone. Then open the hood of the car and find the wire that leads from the battery to the generator, which supplies the necessary signal when the ignition key is turned. The wire should be disconnected and a battery should be inserted in its place. Give the car a good push. If possible, it is better to push it down the hill, then jump into it while moving and quickly turn the key. Remove the battery after the engine starts without turning it off. Of course, this method requires a certain speed of reaction, but when there is no other way out, absolutely anything can happen.
If there is liquid inside, you can remove it from the hood of the car and gently shake it several times so that the liquid components are evenly distributed throughout its entire body. Of course, it is important to observe the greatest possible safety precautions.
Making a homemade charger
If the driver has enough time and appropriate conditions, you can try to make a simple device yourself.
Making a homemade charger will be successful if you have the following components:
- ordinary light bulb (from 60 to 200 watts);
- semiconductor diode ;
- wiring with terminals with plug for socket .
The higher the power rating of the light bulb, the faster the car battery will charge. However, you should not use a light bulb with a power rating greater than 200 watts: not only the semiconductor, but also the battery may burn out. You can touch any element of the circuit being built with unprotected hands only if it is disconnected from the power source. It is important to remember that the circuit will be under very high voltage.
A semiconductor diode is necessary to convert alternating current into direct current during the charging process. When drawing up a circuit, you need to take into account that the diode will take half of the alternating current, so the power of the burning light bulb will be half as much.
The average duration of such charging is about ten hours.
If at the moment there is no time to charge the battery for several hours, but you urgently need to “revive” it, you can use a very simple scheme for making a “fast-revitalizing” charger.
Making a charger using a laptop charger
For this you will need:
- laptop charger ;
- multimeter;
- bulb;
- wires connecting circuit elements s.
The idea is to apply voltage from the charger to the battery. To do this, the positive pole from the internal contact of the laptop charger must be connected to a multimeter. A multimeter operating in ammeter mode is needed to monitor the current at which charging is taking place. Next, the “plus” is connected from the multimeter to the light bulb (on average, 20 W), and from the light bulb, the wires are connected directly to the positive terminal of the battery.
The negative pole from the laptop charger is directly connected to the negative terminal of the battery.
If you put together such a simple circuit, you can quickly do it within 30 minutes.
By the way, if the battery is discharged in the cold, its performance can be quickly restored if you simply bring it into a warm room. At the same time, you should not rush and, moreover, you should not conduct any experiments using hot water or boiling water. The battery must be warmed up carefully and gradually.
Any experienced driver will always be able to answer the question of how to charge a car battery without a charger. Many motorists are happy to talk about this and share their experience with beginners. In order to apply this or that method, it is important to always take into account factors such as the environment, the ability to turn to someone for help, as well as your own ingenuity and ingenuity.
Many of us have had to deal with a situation where our mobile phone is dead and we don’t have a charger at hand. Most often this happens either away from home when the charger is left at home, or if the charger suddenly fails. The question immediately arises in your head about how to charge your phone without charging.
The luckiest ones in this situation are the owners of some Nokia models. They have an invaluable advantage over others. Their phones have a battery backup that can be easily activated by dialing *3370#. After this, the mobile phone will reboot using the backup battery. Alas, this method is not available to everyone.
Charging at home
You can charge your phone without a charger at home relatively easily. The following methods are suitable for this:
- charging via USB. Everything is simple here. If you don’t have a charger at hand, but have a cable with a USB output, you can charge your phone using a computer or laptop;
- There is a more complicated way. If you have an unnecessary charger at home for some other phone, then you can do the following: cut the wire closer to the plug, remove the braid with a knife, and strip the insulation on the wires. Now all that remains is to remove the battery from the phone, determine the polarity and connect the blue wire to the “plus” and the red wire to the “minus”. Secure the wiring with electrical tape. If you don’t have one at hand, use tape or a medical plaster. The resulting design can be plugged into an outlet;
- If you can’t find a power adapter at home, try looking for a rectifier and any cord with a plug and two bare wires. The procedure is as follows: we pass one of the wires through a current rectifier and connect it to the “minus” on the battery, and connect the second wire to the “plus”. Secure with insulating tape and plug in for 10-20 minutes;
- You can also just walk around your neighbors, there is a high probability that they will have the charger you need, which they are ready to lend you for an hour in exchange for, say, a chocolate bar. At the same time, establish friendly contacts, and this is always pleasant and useful.
On my way
But what to do when you are away from home? Is it possible to charge a phone on the go? It’s possible, and there are quite a few options for recharging. If you're lucky, you may come across a special machine where, for a fee, you can leave your mobile phone to recharge; in the absence of such a service, you'll have to figure it out yourself. Someone makes a power source from ordinary batteries and wire. Some craftsmen are able to invent a charger even from an apple and a pair of aluminum plugs. However, instead of running around in search of fruits, it is better to acquire one of the useful devices in advance:
- the so-called “frog”, with which you can charge the battery of any phone. All you need is access to an outlet;
- a device for charging a mobile phone, powered by a AA battery or solar battery. It will save you from losing connection with the outside world, even where there are no electrical outlets.
Both devices are quite easy to find on sale, and they are not too expensive.
In the field
It happens that the ability to make a call literally becomes a matter of life and death. In this case, you will be helped by methods that allow you to revive a low battery for a few minutes, which is enough for one call:
Firstly, you can heat up the battery by simply placing it in a warm place or even over a fire. You can then make a call lasting up to three to five minutes.
Secondly, you can gently tap the battery. Sometimes it helps to make a call for about thirty seconds.
Third, you can seal the service contacts on your mobile phone battery with something. These are contacts that are not marked with a plus or minus. You will have about a minute to call after these manipulations.
Fourth, there is a very radical option. Pierce the battery with a nail and place it in water for about five minutes. As a result, you will be able to make a minute-long call.
After using these methods, you will have to replace the battery with a new one, but in an emergency situation, for example, if you are lost in the forest, you will be able to make a rescue call.
Be ready
One way or another, anyone can find themselves in a situation where the battery on their mobile phone is dead and there is no charger. It is much easier to deal with this problem at home. And on the road, a solution is often found quickly. But, if you plan to go further away from civilization, you should prepare in advance:
charge your mobile to the maximum;
disable unnecessary functions in it, such as Bluetooth or GPRS, do not turn on the radio and do not play games - all this very quickly eats up the battery life;
take a spare battery with you;
If the battery for your phone is too expensive to buy in reserve, buy the most basic cell phone as a backup option.
All this will help you always stay in touch and not be out of reach.
The process of charging a laptop without using a charger is a rather difficult, but quite doable task. In this article, we will tell you in as much detail as possible about ways to implement means of recharging a laptop if you do not have a native and, importantly, working power adapter.
Due to the fact that the actions of charging a laptop without a power adapter require direct intervention in the operation of the laptop computer, it is important to make a note regarding the automatic solution to problems with turning on the device without using a battery and charger. Thus, after carefully studying the instructions, you can not only replenish the battery energy, but also make the laptop work without a built-in power source at all.
Among other things, you should understand some additional aspects that include possible computer problems and are directly related to the reason for the need for this type of charging. Going deeper into the essence of what has been said, before following the recommendations from the instructions, be sure to make sure that the laptop is in working order.
Be extremely careful when performing any actions not originally intended by the manufacturer! In general, even after strictly following the recommendations, we cannot guarantee that the device will charge to normal levels. Moreover, complications may well occur, for example, in the form of a short circuit and burnout of the laptop’s internal power components.
Method 1: Charge the battery without a laptop
This method of charging a laptop consists of disconnecting the battery itself from the laptop computer and, by using some tools, replenishing the energy supply. In this case, you may still need a power adapter from the laptop, which, however, is quite possible to replace with any other that meets the requirements of the technical specifications.
Please note that as part of our detailed instructions for this method, we also covered the possibility of replacing the battery with a new component. Based on the topic of this article, these notes may well be useful, since by replacing the old discharged battery with a charged new one, it is possible to restore the laptop to full functionality.
Method 2: Use a direct connection
By analogy with the first method, this method is extremely radical and is intended for users who, at a minimum, have had experience working with certain electrical appliances. Despite this, of course, even a beginner can cope with the required tasks, however, if the slightest doubt arises, it is better to go straight to the next section of the article.
A laptop can become unusable due to incorrect actions and violations of safety rules.
Moving on to the essence of the direct connection method, it is important to make a reservation about the small number of existing methods. As a result, no matter which charging option you choose, you are faced with certain requirements that are generally equivalent to purchasing a new charger.
Having decided on your priorities, you will need to prepare in advance a couple of small wires with soft copper cores and any sufficiently powerful external power supply, the voltage from which should at least be equivalent to a standard adapter. Please note that if there is a lack of voltage, the battery will still be charged, but not completely.
The lack of voltage of the power supply used will most likely manifest itself in significant declines in the performance of the laptop.
To avoid problems, you should work with the laptop turned off and the power adapter unplugged. It is also advisable to remove the battery until a channel for transmitting electricity to the laptop is established.
- center - «+» ;
- edge – «-» .
The neutral line usually passes through the negative terminal.
Once you've finished connecting the wiring, you can move on to the power supply, depending on its value.
In addition to what has been described, you can do things a little differently.
When the adapter you choose is slightly more powerful than the original one, you should take special care to prevent overheating of the laptop components and the battery itself.
This is essentially the end of the method, since after following the recommendations all that remains is to install the battery and wait for it to fully load.
Method 3: Use USB ports
As you know, today a fairly large number of possibilities are provided by standard USB ports available on literally any laptop computer. These additional features rightfully include charging the battery without using the original charger.
It should be noted that although special cables can be purchased without any problems at any electronics store, they still have certain requirements for the device being charged. This directly concerns the presence of a modern USB 3.1 port on a laptop computer, capable of transmitting the necessary impulses.
You can find out about the presence of such an input by reading the technical specification from the computer, which describes all the available ports. Typically the socket you need is called USB 3.1 (Type-C).
So, how to charge a laptop without charging via USB:
Of course, thanks to this approach to replenishing energy in batteries, you can use all the capabilities of laptops without any visible restrictions.
Method 4: Use an external battery
This method, unlike others, allows you to charge your laptop not only at home, but also anywhere else. What's more, you still aren't required to charge a laptop as standard.
Please note that an external battery, called a Power Bank, is designed to charge not only laptops, but also other portable gadgets. Depending on the type of battery you purchase, you can charge several devices at once.
The devices shown in the screenshots within the article are not recommended - the choice is up to you.
Using this approach, especially if you have multiple drives, you can increase the standard laptop battery life limit to the same level as a standard power adapter.
Method 5: Use an auto-inverter
Many car owners and at the same time laptop users have encountered the problem of a lack of standard battery charge when actively using the computer on the go. In this case, the ideal solution to the problem is a special automobile converter that converts the base voltage of the vehicle.
It’s worth mentioning here that you can use such a device either with or without a standard power adapter. However, given that in your case there is most likely no charger at all, you will need an additional USB adapter.
In addition to the above, it is quite possible to purchase a car power adapter for your laptop and charge the computer using it through the cigarette lighter. However, such power supplies are usually supported by a limited number of laptop models.
This method, as you can see, is rather additional and is suitable as a solution in isolated cases.
Method 6: Use an electric generator
In modern realities, many users resort to using gadgets such as solar panels or any other portable generators to charge their personal devices. This attitude towards such types of recharging is quite justified, since the battery is often replenished quite quickly.
The main negative feature of such gadgets is their dependence on certain weather conditions, which makes using them at home somewhat difficult.
- The first thing you need to do is purchase the device you need from an electronics store.
- Don’t forget to check with your consultants about the gadget’s power, touching on the topic of recharging your laptop.
- When you have the device with you, use the appropriate adapter to connect the power generator to the laptop's charging socket.
- Usually the required set of adapters is supplied with the gadget.
- After connecting, make sure that the source works without any problems.
- Over a period of time after starting, the energy will gradually transfer to the laptop's base battery.
In our case, this is a solar battery, due to its maximum compactness.
Such generators are capable of storing voltage, being a kind of Power Bank. That is, for example, you can leave a solar battery in the open air and soon it will be able to power all your devices.
Storage capacity depends on the generator model.
This concludes the instructions.
Regardless of the battery charging method you choose, you will be able to replenish the battery's energy reserves. And although all methods are fairly equivalent, in the absence of the necessary parts and knowledge, it will still be much more profitable to acquire a new power adapter.
Is it possible to charge a phone without a charger at home? Many people are interested in this question. Since chargers are often lost and broken.
It’s good if you have a universal frog on hand. But not every home has it. What if the phone dies on the street?
What to do? We will look for options to solve the problem. You won’t be able to recharge your gadget while outdoors, even if you have a charger with you. After all, the battery requires electricity.
But, while in a room, office or car, you can use the following instructions:
Find out the charging time of your battery
1. You can charge your phone without charging it using a USB adapter. Connect it to a desktop computer, laptop, tablet. The charging process occurs only when PC mode is turned on. This way you can solve the problem with both a regular phone and an iPhone. It is only important that the connector in the panel matches the USB plug.
USB adapter
2. If there is no suitable cable, you can use another method. You will need any old but functioning phone charger.
The following manipulations should be carried out:
- At the end of the cord at the connector, cut off the wire;
- remove the insulation braid with a knife; examine the wires: blue and red should be visible;
- Put the wire aside for now and remove the battery from the phone. Find “+” and “-“ at the contact points. Take a cable with exposed wires. Connect red with minus, blue with plus;
- For optimal contact, the wires must be secured with electrical tape. You can use regular tape;
- the other end of the wire (with the plug) should be plugged into the outlet. This way you can charge your phone battery without charging it.
3. There are other methods to solve the problem. You can charge your phone without using a frog charger. This is a special device that has two terminals. With their help, mini batteries are recharged. To use this method you need a power outlet. The frog is not an expensive thing and is very convenient if the “original” charger is lost. You can carry it in your purse and take it with you everywhere. Using the frog is simple. If you have no experience, you can watch a detailed video on this topic.
Charger "frog"
4. The next method is charging with a device that operates from a solar battery. In this case, you don’t even need an outlet. Having a device that works “from the sun”, you can recharge gadgets on the street, in nature, etc. You just need to have a cord that fits the phone connector. It is connected to the device and placed in a sunny place.
If your phone does not have a charging socket
There are different cases - the nest becomes clogged, destroyed or increases in size. The latter happens when the phone's power cord is frequently plugged in. The socket becomes larger and does not make contact with the charger. In addition, the connector may become clogged, and the debris cannot be removed and connected to the charger. What to do if the gadget is fine, but you can’t charge it? You don't have to buy a new phone. There are ways to charge your phone without a charging socket.
You can go to a service center and have the device repaired. The nest will be properly cleaned. It’s better not to start this process yourself; you could completely ruin your phone.
Take out the battery and place it in the frog to charge. It is important to ensure that the contacts match. There are metal strips visible on the battery that should be adjacent to the terminals of the device. Once charging is complete, return the battery to its place. This solution is temporary and it is better to send the equipment for repair.
If you are on a hike or relaxing with friends at the dacha, if you went to visit relatives on the weekend or currently want to make a parachute jump, but your phone is completely discharged - no problem! We'll give you some tips on how you can charge your phone without charging it, so you can call your mom or take a selfie with the Grand Canyon in the background.
Charging using a computer or tablet
You can charge your phone without a charger using the USB cable that comes with any mobile device. It is enough to have a USB connector in your computer or tablet. If you do not have the necessary cable, you can ask your neighbors, for example, or friends. Most USB connectors for mobile devices are standardized.
Charge your phone using an old cell phone
The second method is useful for those who do not have a charger, USB cable or computer. You will turn into real physicists. For this method, you will need to charge an old mobile phone (in every home there are about ten unnecessary old chargers). Next, take a sharp knife and cut the insulating surface in a circular motion. You should see two wires: blue and red. Next, you need to remove the battery from your phone and carefully examine the golden colored contacts, you should see a “+” and “-” charge. It is necessary to connect the blue wire to the contact with the “-” sign, and the red wire to the contacts with the “+” charge. After this manipulation, rewind your charger with insulating tape and under no circumstances touch the exposed wires.
Charge your phone using AA batteries
On a hike where there is no electricity, neither a USB cable connected to a computer, nor physics skills and mechanical operations with an old charger will help. Before long trips, it is better to buy yourself a cheap small battery cartridge. This type of charger usually comes with several adapters. To fully charge your phone you will need 5-8 AA batteries.
Charge your phone with lemon or potato
It is quite possible to charge your phone using a lemon; one lemon produces a discharge of approximately 1 volt. In order to charge a mobile device to 100%, a charge of 5-6 volts is required. So if you create a chain of six lemons, then it is quite possible that the phone will work. Why is this happening? Lemon juice works as an electrolyte for two metal wires made of nickel or copper. The principle of operation of potatoes is approximately the same, but for a normal full charge you need about 400 potatoes.
Some desperate ways to charge your phone
There are several other ways to charge your cell phone, but they may negatively impact your battery performance in the future. If you are outdoors where there is no way to charge your phone without charging using the methods described above, then there are several questionable methods. First, if you're camping, build a fire that can heat the blade of your knife. It is enough to touch the phone battery with a knife for a few seconds and the charge level can reach 4%. There is another most desperate method. Take the battery out of the phone and lightly hit it with a stone. The pressure inside the battery can increase the charge, which will last for a couple of calls. Of course, the lifespan of the device may be shortened.
We really hope that our advice will help you find a way out of a difficult situation. Remember that it is better to prepare in advance and charge your phone properly. Don’t despair if something goes wrong and you’re not in touch, because it’s quite possible to revive a phone without charging.
