Today you will learn how to charge your phone without electricity. We will look at really working, and most importantly, adequate ways to charge your phone without electricity. Also, you will learn how to charge your phone without electricity and not damage your phone. At the end of the article, we will present methods that should never be used to charge the battery of your smartphone.

Charge your phone without using a charger

Most owners of mobile gadgets have no idea that, in some stores and outlets for other services, chargers are also on sale. In addition, there are terminals where you can charge your mobile phone. It’s a pity, but in our country, they are still available in two capitals and other large cities. But, if you find them, feel free to charge your phones!

Unfortunately, such charging costs money. On average, 50 rubles per hour. If you are walking along the central square and there is a store of your operator nearby, you can contact him with such a request. You should not be refused, since such a service is part of the service provided to subscribers of your network.

But, for the most part, there will be no such service. In this case, let's try to charge the phone without a charger. You can simply use the Air function. In this situation, you can fully charge your smartphone after an hour. If this option does not suit you, then you can recharge your smartphone a little if you turn off the Internet and the GPS network. Only your card should work. However, programs need to be disabled.

Mini wind generator - does it work or is it just a toy?

Today, wind energy is used very widely, especially in areas with constant winds.

Are there pocket wind generators that cannot replace thermal power plants, but are suitable for hiking? After all, we don’t need to power residential and industrial areas, we want to charge a smartphone. We will not delve into the laws of aerodynamics, but simply turn to ready-made developments. Here is one of them:

You can buy such a miracle for “only” 500 rubles by following the link. Will this Carlson be able to “pump up” a smartphone? Let's look at the characteristics:

Motor size: approximately 24.5mm x 34.2mm.
Fan diameter: approximately 90 mm.
Output voltage: DC 0.1-6V.
Output current: 0.01-0.3A.
Rated speed: 200-6000 rpm.
Output: USB 5V (+/-0.2 V).

Together with the photo of this fan, such “characteristics” are, to put it mildly, frivolous. The range of each of them is several orders of magnitude. Output current – 0.01-0.3 A. How can you understand this? What does "approximately" mean? Their generator and impeller are stamped “how will it turn out”? And if you take into account the phrase “A wind generator is capable of producing a voltage of 5V, which is quite enough to charge the batteries of modern smartphones and tablets,” then it becomes sad... It turns out that a pocket wind generator is a myth? We are looking further.

Next development:

Let's take a look at the characteristics:

output voltage – 12/24 V (auto);
output power – 400 W;
minimum wind speed – 13 m/s;
weight – 10 kg;
blade length – 600 mm.

Quite good, and even more than needed for our purposes. But the weight and dimensions... Such a power plant is perfect for constant use at a non-electrified facility, but you can’t carry it in a backpack. Brought, installed, and for the whole season. In addition, this device requires a decent amount of wind. Nevertheless, the generator copes with the task set by us with a bang. It costs about 16,000 rubles, lives on Aliexpress at the link.

And here is another wind generator from Janulus (Ireland), released for sale in 2015. Unfortunately, we did not find it in online stores, but, nevertheless, it exists and is sold:

Characteristics of the Trinity 50 tourist wind generator:

power – 50 W;
output voltage – 5 V (USB);
minimum wind speed – 2 m/s;
built-in battery capacity – 7,500 mAh;
dimensions in stowed position – 300 x 55 mm;
dimensions in working position – 600 x 900 mm;
weight – 600 g (with battery).

It's a completely different matter! What a tourist needs. Firstly, it is compact and not heavy. Secondly, it can operate in winds of only 2 m/s. This kind of wind is not a problem even at ground level. And thirdly, the wind generator has its own battery of decent capacity. There is wind - I charged the gadget from the generator. No - from the battery. The device costs about 15,000 rubles.

So, miniature wind generators that can charge a smartphone and even a laptop exist. This is not a myth.

How to charge your phone battery without charging

There are quite a lot of different, unusual methods for charging a smartphone. These methods are best used in extreme situations, since the use of such methods is often a consequence of battery failure. But what can you do if you are in the forest, where, of course, they don’t sell chargers, but you urgently need to charge your phone? Even if you have a charger, you won’t be able to connect it anywhere. In such a situation, you need to apply one of these options.

Unusual methods for charging a smartphone battery

Let's try to dent the battery. You can tap it on a tree trunk. Also, some people bite the battery a little. But, this method is used when you don’t really need the battery, since it may become damaged and will no longer be able to absorb charge;
If you are going outdoors, I advise you to buy a solar battery charger. In this case, I think this is a great solution!
Try heating the battery. You need to put it on any object, but only a warm one. You need to make sure that the battery does not melt. When you heat the battery, a chemical process will occur inside it, which will add about 10%. Of course, this is not a panacea, but it can help you in a difficult situation or trouble;
You can also hit the battery on a heavy surface. This will also help start some of the chemical processes inside it, and the battery will be charged by 10%. This energy capacity may be enough for the desired call. Of course, you won’t be able to browse the Internet, but you will have enough energy to call the right person;
In addition, you can try charging with lemon. Take the charger (if you have one) and insert its plug into 2 lemon halves. The phone should charge a few percent, which should be enough for one important call.

Portable dynamo

Surely many people remember such a device as an electricity generator for bicycles. Such a “twist” was placed on the front wheel and fed the bicycle’s headlights.

Today, devices of this kind are found for manual rotation of a special handle on the device body. There is also a USB connector to which you can connect a rechargeable device – a smartphone or tablet.

By rotating the handle, the user sets in motion the induction current coil or frame, depending on the design. This creates a miniature power plant. By the way, modern nuclear power plants operate on exactly the same principle - electromagnetic induction. True, it is no longer a person who acts as a rotational force, but nuclear fuel.

The disadvantage of this method, how to charge a phone without electricity , is obvious. Charging occurs only while the handle is rotated. You'll have to work hard to raise your smartphone's battery charge to an acceptable level.

How to make a charger with your own hands?

There are various unique methods that can help you charge your phone without charging it. This method is suitable when the user finds himself in nature, where there are no charging devices. Of course, if the user has a charger, it is of little use if it cannot be connected to an outlet or the car's cigarette lighter.

You need to find a decent sized pipe. A larger pipe will produce more current. After this, we bury a pipe or some kind of metal piece into the surface of the Earth so that a small piece of metal peeks out from the Earth;
We connect a wire made of copper to a piece of metal. Then, connect it to the battery. Next, we are looking for an electrolyte. It can be a solution of salt or regular salt. Even if you don’t have salt, use chicken broth or lemons;
It even contains salt and can serve as an electrolyte. In addition, you can use river water if it is nearby. If the water has been purified, it will not work. This water contains few minerals. From here, the water will show small electrical signs. So, when there is a river nearby, we pour water over the created structure.

How to charge a smartphone when the charging slot is broken?

Many phone users have found themselves in a similar situation, because if you charge your smartphone frequently, the terminals will wear out faster and become damaged. Therefore, the slot often goes out of working order. Of course, the easiest way to do this is to give the phone to a technician so that he can fix it. Repairs will not cost much. But the master may not be at the workplace and so on.

Let's try to charge the battery directly. You need to take it out of the smartphone and get the charger. Remember, it is better to take an old unnecessary charger, as you will damage it;
So, we cut off the connector that connects to the smartphone. Next, you need to separate the pair of wires that are together under the insulation. Using a blade or knife, remove the insulating layer from these wires so as to obtain thin bundles of copper;
So, we take a blue marker and make a mark with it on the wire that we will have (-), use a red marker to mark (+). On phone batteries, manufacturers usually label where they have (+) and (-). So, unplug the charger from the outlet. After that, we fit these wires to the marks made with a marker on the battery. After this, the wires can be attached to the battery. For example, electrical tape or tape. After that, connect the charger to the outlet;
After some time, your smartphone will be charged. Attention, these methods may damage the battery. Hence, they should be used in case of emergency. When you use these methods repeatedly, the battery will most likely stop working.

Plug it into an outlet

Your computer's USB port may be handy for charging your phone while you work, but a wall outlet will charge it faster. This is because USB ports typically only charge at 0.5 amps, so it will take twice as long to charge your phone than using the 1 amp power adapter that comes with your smartphone.

We charge a smartphone without a slot using a frog

This is a fairly common charger, reminiscent of a device that is plugged into an outlet. The frog has sliders and special clamps that help secure the battery;
We spread the antennae in the opposite direction, equal to the segment between the terminals (+) and (-). We connect them and clamp them using a clamp. Then we connect the created structure to an outlet;
Some experts claim that this option can wear out the battery quite quickly. From here, it is better to repair the cable and connector for charging using the usual method.

Charge your phone battery using an adapter

Some users carry several batteries in their pockets, because in the event of a power outage, all they have to do is insert a new battery and they will not disappear from the network. At the same time, while one battery is working, the second one is charging. But, in this case, you need to take a second phone to remove the battery from it. And when one battery runs out, the second one may not have time to charge. Let's solve this problem.

This action can be performed using a standard adapter. In this situation, the adapter has several cables, and most users will figure them out fairly quickly without damaging them;
Therefore, if the connector is shaped like a pyramid, the user still needs to cut off the tip and split one wire into 2. But, if you do not want to harm charging, use a charger from an outdated smartphone;
You can also use a tablet charger or a laptop charger. The main thing is that the plug is round in cross-section and with a current strength of 5A and 20v. Let's continue our design to charge phones. Let's take a certain number of wires made of aluminum or copper. Also, we need electrical tape;
This device needs to be connected according to the option that we discussed above, but a little differently. You need to insert one of the copper wires inside the slot, and the second should be outside, they will have a charge with different poles. From here, a person will transmit (+) and (-) using these copper wires.

Common questions and answers

Vyacheslav

For several years he worked in mobile phone stores of two large operators. I understand tariffs well and see all the pitfalls. I love gadgets, especially Android ones.

Ask a Question

Question to the expert

The connected phone does not charge and the charging indicator does not appear

Most likely, the problem is in the “charger” or cable. You need to try charging the gadget with others. It is also possible that the gadget's USB connector may break. Only repairs will help here

There is a charging indicator, but the smartphone is not charging

The power controller is probably broken. The problem can only be solved by repair

Battery drains in a matter of hours

The most common cause of the problem is an old battery. In this case it needs to be replaced

The battery charges at different speeds, quickly loses charge, behaves strangely

Perhaps the problem is in the firmware. It's worth trying to reset it to factory settings. You can also install custom firmware. But this should be done only if the user is confident in his abilities. Otherwise, you can ruin your phone

How to make a phone charger with your own hands at home?

Do you know that it is possible to charge a smartphone without a charging device using AA batteries?

So, we need AA batteries and a special device that outputs the contacts. Typically, such devices are available in stores that sell radio equipment;
So, we insert four batteries into the battery slots, and the terminals need to be connected to the battery contacts. Then, we secure them with electrical tape (you can use tape);
The voltage will be 6V. This is quite enough to charge the battery a little more than 50%. Do not expect the battery to be fully charged.
