How to charge your phone without a charger and an outlet?

Despite the rapid development of mobile technologies, expanding the functionality of modern smartphones does not always bring only benefits.

New features often require more power, resulting in shorter battery life. Everyone is familiar with the situation when you need to make an important call or urgently access the Internet, but a low battery does not allow you to do this. It’s good if you can use the nearest outlet and replenish the battery using the power supply. However, far from home, for example, while traveling, this is not possible. There are several great ways to charge your phone without a charger.

Recharging using the “frog”

Only owners of smartphones with a removable battery can use this method. You need to remove the battery from the phone and then place it in a universal frog charger. In this case, you need to make sure that the polarities (plus and minus) on the battery and the terminals of the device are opposite. After the “frog” is connected to the outlet, the charging process will begin.

Emergency and dangerous methods

We have looked at safe schemes, now we move on to dangerous and even extreme ones. Use them only as a last resort.

Through the "frog"

The “frog” will help you recharge your phone quickly and without a charger. No, representatives of tailless amphibians definitely have nothing to do with it. This is the name of universal chargers that allow you to charge any battery. True, they are only suitable for handsets with removable batteries. The procedure looks like this:

We remove the battery from the phone.
We clamp it in the “frog”, making sure that the contacts make contact.
We connect the charger to the network.

The method is dangerous due to the possibility of the battery exploding, but we are considering an emergency. Our task is to ensure that the extreme contacts of the battery are in contact with the contacts of the charger. No one, not even the manufacturer, can guarantee the integrity of the battery after this procedure. The disadvantage of the scheme is that many phones today are produced with non-removable batteries.

Direct connection to battery

The procedure is no less dangerous than the previous one. The task is to connect two batteries between each other. This often leads to their mutual heating, so it is better not to experiment with this circuit. And some people remove the batteries from their phones and charge them directly from the power supplies of various devices (game consoles, portable radios, etc.). The supply voltage may differ from the desired one; no charge control circuits work here - this can lead to overheating of the battery followed by an explosion.

Impact charging method

Quite an original technique. You could even call it radical. The task is to remove the battery from the phone and push it against the wall, flatly. The technique allows you to “catch” a couple of percent of the charge, which is enough for a call. But it can damage the battery. Damaged batteries may explode during subsequent charging.

Charging with AA batteries

You can also replenish the battery on your smartphone using a charger that runs on AA batteries. As with previous types of devices, a USB adapter is required here. The disadvantage of this method is the need to constantly buy new batteries, but in case of urgent need, they can be borrowed from the TV remote control, flashlight or alarm clock.

Charging your phone via USB port

If in the house, or in the place where you are, there is a USB cable and a computer, laptop, tablet, mini PC or TV with the appropriate connector, then you can charge your phone without any problems. What to do: insert the cable into the main device (op-amp) and watch it charge. An important condition is that the phone must have a working socket, and the op-amp must be fully charged or connected to the network. The charging speed under such conditions is no less than when connecting a conventional charger.

As a rule, the standard package of smartphones includes a USB cable (mini or micro depending on the type of gadget). The wire can also be found in the packaging of a camera, tablet, e-reader and other devices. There shouldn't be any difficulties. The cable can be designed to connect several phones at once.

Application of Dynamo

Another useful device for replenishing your smartphone battery when away from a power outlet is a dynamo. Unlike solar panels, this device does not require cloudless skies to operate effectively. The dynamo converts mechanical energy into electricity - only after the user twists a special handle for several minutes. Thus, it is quite possible to charge the battery by a couple of percent in case of urgent need.

Solar panels for charging

Solar panels are an effective way to charge your phone without charging. The method is relevant if you are in an open area, in nature, far from civilization. It is necessary that the weather be cloudless or partly cloudy. The charging principle is simple. The small unit is equipped with photocells, the cells of which absorb solar energy and transmit it to the phone through a cord.

Such a device can be intended for one or more gadgets.

Solar panels store energy for a long time, but they will charge the device more slowly than standard charging.

This is because the photovoltaic cells themselves are very small and cannot produce more energy.

Lemon, nails, copper cord

Now you can move on to more extreme charging methods, the use of which is associated with risks to both the battery and human health.

To implement this idea you will need a lot of lemons. The more of them there are, the more you can charge the battery. You need to stick a nail into each fruit, connecting them together with copper wire. Its free ends must be connected to the previously removed battery of the device. This will allow you to replenish your stock by a few percent, which is sometimes very important.

Sometimes you can charge your phone this way:

PowerBank for phone

Almost every user has an external battery, or PowerBank. This is a real salvation for those who practically never let go of their phone. The device has a corresponding charging connector and a USB cable that connects the gadget to a power source.

In a few minutes, the mobile phone will receive a certain percentage of charge. The main condition for the operation of an external battery is that it pre-charges itself. This energy source has a delivery speed no worse than that of a standard charging device.

Direct connection to power supply

The following procedure can only be carried out with rubber gloves. First, you need to strip the end of the old charger with a knife to expose the two wires (red for positive, blue for negative). Next, you need to move them slightly apart and connect them to the opposite contacts of the smartphone battery. Having secured the device with electrical tape, it must be connected to a power source.

There are quite a few ways to return a couple of percent of charge to the battery. Of course, it is recommended to use the last three of the above methods only at your own peril and risk, since you can cause irreparable damage to the phone and battery. We recommend that you take care of this problem in advance.

Induction charger

The developers of some iPhone models and mobile phones on the Android operating system provide a wireless or inductive charger. The charger looks like a round or square platform. You need to place the phone on it and, thanks to the alternating magnetic field, the cell phone will receive the energy necessary for operation.

This charger is sold in any mobile accessory store, but you need to get used to it. The downside is the short range, which means that the gadget needs to be laid out in a special way to ensure charging. This type of charger is very popular among mobile phone owners whose corresponding connector is broken.

We charge the phone in extreme conditions

A dead gadget isn't that big of a deal if you're outside within the city limits, and there are plenty of options for charging your device. It’s another matter when the battery percentage is melting before your eyes, and you are in the forest, for example. Of course, if this “thicket” is a small landing not far from the city, then it’s okay, but in the case when the phone was used as a navigator and suddenly stopped working, a real problem will arise.

Here are a few methods that will help in cases where you are far from home and civilization in general:

we use a knife and fire - heat the knife blade over an open fire and apply it to the battery. Then we return it to the mobile phone and get the opportunity to make a 5-minute call, which in extreme conditions is worth its weight in gold;
for physics lovers - 2-3 metal plates are wrapped with copper wire and buried in the ground, this structure is watered with salt water and connected to the gadget using wires from the charger.

Of course, it is far from a fact that every hiking backpack always has such a set. But if you have to go outdoors, it’s better to take all these things in case your mobile phone runs out.

You cannot bring the knife to a red-hot state, because if exposed to too high a temperature, the battery will simply swell and may even explode.

In practice, this method may not last long: it is just a way to squeeze all its charge out of the battery by heating

These and other “wild” methods of charging mobile devices are best seen in action.

Still, the most convenient way to keep your gadget charged in the forest is to take with you an external battery with photocells that can absorb the energy of sunlight and transfer it to any device.

Even in the forest, where there is not much sun, such a battery can be fully charged

Press and release the power button

If the previous methods did not work, try putting the phone on charge, pressing the power button and wait a few seconds (5 - 10 seconds). If nothing happens, release the key and try again after a couple of seconds. Do the procedure for 2 - 5 minutes. Sometimes it helps to disable the controller, which often locks the device when completely discharged.

In rare cases, the cause of problems with your phone may be a SIM card or memory card whose contacts are dirty or oxidized. Remove them and try to start your smartphone. If the phone works, carefully wipe the card contacts. In case of failure (the phone does not work again), change the SIM card and SD memory.

If this option does not revive the phone, proceed to the next steps.

How to save battery power if there is little left

If the phone has not yet turned off, but there is little charge left in the battery, try to save it. Perhaps the phone can survive until the next recharge:

Turn on power saving mode on your phone. The phone itself will turn off functions and components that are currently unnecessary and reduce the screen brightness.
Disable Bluetooth, Wi-Fi, mobile Internet (“Data transfer” option). All these networks drain the battery a lot. You can immediately put the phone in airplane mode - everything mentioned above, as well as, in principle, the SIM card network (cellular communications) will be disabled. But in this case they won’t get through to you.
Reduce the brightness of the display yourself - set it to the lowest possible.
Quit all programs (close them in Task Manager).
Lock your phone (so it runs in the background) with the power button and take it out of this state as little as possible.
If the situation allows, turn off the device completely. Turn it on only when you need to make a call.
Do not leave your phone in the sun to prevent it from heating up. A heated battery discharges faster.

If you don't have a charging adapter but only a USB cable, connect your phone to your computer using this cable. If your USB output is broken, buy a “frog” for a while, but try to fix the connector itself as quickly as possible. If you are on the road and do not have access to electricity, use a Power Bank or an adapter to charge from your car's cigarette lighter.

From car charger

In some situations, you will need to know how to charge the battery without a phone directly in the car. If a person is often in his vehicle, then the question of ways to replenish the level of tension is relevant for him. To do this, you need to connect it to the cigarette lighter using an adapter.

No. 5. Charging from pieces of metal

This method will also help in the wild. We will create a galvanic cell. For it we will need some metal objects. Pieces of pipes, corners, etc. will do.

Stick them vertically into the ground. Wrap with copper wire. If you don’t have one, any other will do, but it will be a little less effective. Bring out the ends of the wire and connect to the battery.

Now you need some kind of alkali. These could be, for example, saline or soda solutions. The metal part of the structure is doused with liquid, which acts as an electrolyte. As a result, you get a current that you can use to charge your phone using a wire.

The voltage of such an element is low - 0.5-1 volts. However, remember that if necessary, you can make several of these elements and connect them in series. This way you can achieve the required voltage to charge your phones.

A nice bonus of this method: it can function for quite a long time. The main thing is to moisten the soil with an alkaline solution from time to time.

Use different batteries

Using this method, you can charge your phone battery without the phone itself.

To do this, you need to perform the following algorithm of actions:

Open the cover and remove the battery from the mobile phone . Models with a non-removable battery do not have this option, which means the described method will not work. Most smartphones on Android and Windows provide such a feature by design, but you should not try to remove the back cover from Apple devices; the manufacturer does not provide for this.
Find several AAA, AA or nine-volt batteries . Their internal energy is completely identical to that found in the phone battery, in contrast to the current from the outlet, which is characterized as alternating. Why shouldn't you try to directly use AA batteries instead of your own phone battery? Because its fine design and settings are very sensitive to the characteristics of the incoming energy, and deviations in them, characteristic of the connected elements, can irreparably damage the device.
Figure out which of the contacts on the found batteries and on the charged element itself are positive and which are negative . If you look closely, you can see icons clearly showing the charge sign. With a telephone battery, it is sometimes difficult to disassemble them; as a rule, the contact with the “plus” sign is located closer to the edge, and the contact with the “minus” sign is further from it. You should pay attention only to the outer protrusions; the central ones serve for other tasks.
Assemble the batteries so that their total voltage is equal to that required for charging . On average, for modern phones, DC charging should be carried out at a voltage of at least 3.7 V. There are 9 V batteries, and you can use them. The usual AA or AAA voltage is only 1.5 V, so you will need at least three pieces so that their total voltage is greater than the required value.
Get two pieces of wire, preferably insulated along the entire length, except for the ends - there should be bare metal there.
Connect the wire between the batteries and the battery being charged, secure the connection with tape or something else. Then put the structure down and wait while the battery charges. If several batteries are used, they can be connected in parallel to each other. To do this, a metal piece of wire is attached to all the negative terminals of all small batteries on one side, and a second wire is attached to the positive terminals on the other.
Of course, you shouldn't expect a large charge . The battery will not be fully charged, but the little that is there should be enough to make an urgent call or other important action.

Precautionary measures

The following recommendations should be followed:

Before removing the battery from your mobile phone, you must turn it off - otherwise some settings may be lost.
Never attempt to charge any of these methods with regular batteries that are not marked “rechargeable” and are not intended for reuse.
Make sure that the incoming charge does not exceed what the battery can hold , this is explosive.

There are a lot of possibilities on how to charge a phone battery when left without a charger, and if you have knowledge about them and about the possible dangers associated with certain methods, then the likelihood of finding yourself somewhere without the ability to get in touch is minimal.

Basics

When powering smartphones, it is recommended to use the “original” wire that came with the kit. If it is damaged or lost, it can be replaced. It is better to purchase a cable that is specifically designed for your gadget.

This does not mean that other means are not available. Any smartphone charger is suitable for replenishing the battery. The main thing is that the plug matches the connector. But third-party wires can damage your phone's battery or shorten its life. Therefore, they cannot be used constantly. This is not a full replacement of the charger, but a temporary solution. As soon as possible, find or buy a special cable that is suitable for the device model.

You can do without charging if you have a MicroUSB-USB adapter and a computer. Just connect your smartphone to your PC. Or purchase an electrical plug with a USB socket. With its help, you will replenish the battery from the outlet, as with a regular charger.

There are also adapters that can be connected to the car's cigarette lighter. This method is suitable for you if you spend a lot of time driving and have nowhere to charge the battery. The smartphone will be powered while the car is running. But fuel consumption will increase slightly. If you turn off the engine and leave the car battery on, the phone will drain it.

A universal option is external batteries. They always come with a suitable cable. Sometimes there are several cables for different types of devices. These products are used at home or taken on the road. Their capacity is greater than that of a telephone battery. That is, they “fit” more energy that you can carry with you.
