a well-known universal device designed to restore the charge of lithium batteries mobile phones and other small gadgets. With a different type of battery, this device cannot be used.

Role in everyday life

Sometimes there are moments when the charging unit from a smartphone or mobile is not at hand, it is irretrievably broken or lost, and it is not possible to purchase it in the near future. In this case, "Frog" comes to replace him. universal Charger. Alternative titles. "clothespin", "toad". This device is equipped with adjustable contacts, to which the battery itself, previously removed from the device, is connected directly. Of course, such a process involves some inconvenience associated with constantly removing the battery and possible failure settings, but sometimes this is the only successful way out of this situation.

Where and what can it be used for?

As mentioned above, this device is suitable for recharging most small-sized equipment, mainly phones and cameras. Usually, the frog device comes with instructions, but the problem may lie in the content of the brochure in a foreign language, since these devices are mostly made in China.

Some useful information

In addition to a cell phone, the Frog charger can charge a camera, a PDA or a navigator, but only if lithium batteries with a small capacity are used. The device is connected to the network with standard voltage. When the battery is fully charged, the device will automatically turn off the power. Typically, this takes about two to three hours.

There are several types of "frog" devices that can be connected to various sources of electricity:

To a regular 220 volt household outlet.
to the car network. 12 volts.
Connecting to PC via USB port. 5 volts.

The most practical and common is the "frog" charger, powered by home network. The choice of type of device depends on the personal preference of each.

Explanation of device designations

Each such device has several indicator lights, next to which letters are indicated to help regulate the entire recharging process:

Full, full. indicates that the battery is fully charged.
Charge, ch. This means that the charging process is in progress.
power, pw. the device is connected to a power source.
con. polarity is correct.
Te. polarity is checked.

Charging "frog". How to use.

In this video I will show you how charge the battery with using charging "frog". Advertising and collaborations:.

How to adjust the polarity manually? First you need to clamp the battery in the charger so that the contacts of the device are connected to the "-" and "" terminals. If the battery has three or more contacts, then you need to use the two extreme ones.

If the polarity is correct when connecting, pressing left button“Te” the green light with the words “Con” should light up, otherwise press the right “Con” button, then “Te” again. On some devices, the “Con” LED may light up when connected without first pressing.

The most convenient models are those that automatically determine the polarity, respectively, they do not have the right button for changing the polarity.

If everything is done correctly, the green “Con” light is on, which means that you can plug the device into a power outlet. At this point, "Power" and "Charge" should turn on. When the battery charging process is completed, the right "Full" LED will light up. Now the device can be removed from the socket and the battery can be used for its intended purpose.

Non-standard situations

If "Con" does not light up at all, then the battery is completely dead and needs a "buildup". In this case, it can be connected arbitrarily in any polarity, and then plugged into the network for five minutes. If “Charge” flashes, it means that charging is carried out correctly, if not, then you need to right-click to change the polarity and see how the “Charge” indicator behaves in this case.

How to use the frog charger?

The classic device is designed for 220-volt voltage, on the back of its cover there are two sliding pins located parallel to each other. they can be separated to the required distance, corresponding to the distance between the battery contacts.

When switched on, polarity can be corrected manually via buttons or automatically. It all depends on what model your Frog charger is.

If the battery is completely worn out, the following situations may occur:

If desired, and with some skill, a do-it-yourself frog charger can be built using a simple scheme.

Batteries with more than two contacts can be charged using the described device, however, for this it will be necessary to disassemble the battery and connect charging to it, bypassing the controller.

Following from all of the above, we can understand that "Frog". a universal charger that is very useful in case of failure of other power sources, small batteries, as well as the inability to charge gadgets in the usual way, which happens quite often. On the this moment manufacturers offer all new devices equipped with a USB port and an LCD display, which greatly simplifies their use.

The presence of a USB port that allows you to charge most devices.
Ease of use.
Versatility.

With frequent use, relative fragility.
Long process of charging capacious batteries.

"Frog". best alternative energy source

Despite a few shortcomings, "Frog". a charger, the price of which is very diverse (from 60 to 650 rubles), is a rather useful thing in the household, if only because it is able to literally revive the batteries of phones and cameras that do not show signs of life. But it should be borne in mind that you need to use this device as needed. Too frequent charging using the "Frog" can lead to rapid depletion of the battery and, accordingly, its failure. Paradoxical, but true.

Despite the fact that these chargers are mainly made in China, you should not neglect such products. On the modern market, you can find universal and unique auxiliary devices that can greatly facilitate our lives and give a second chance to details that would otherwise fly into the trash. Therefore, it makes sense to have at least some idea of how to use the Frog device for the usual recharging of a telephone battery.

The technical devices of the new generation amaze with their diversity. For example, have you thought that charging cords various devices there are so many that it is not enough to count the fingers? And each device needs only its own charge. But there are also universal chargers that can charge any piece of equipment, be it a phone or a camera. This article will consider the universal charging "frog".

"Frog", but not an amphibian

A frog is not only a useful animal, but also a colloquial name for a charger. It is very simple and convenient to use. Operates at the expense of an electric power source with a voltage of 220 volts.

Benefits of clip-on chargers

Charging "frog" has the following advantages:

Versatility. The type of charger in question is suitable for all batteries of mobile phones, cameras, camcorders, pocket computers, MP3 player and other equipment of small dimensions, functioning through the use of a lithium battery.

Ease of operation. To use charging, no additional knowledge, skills and experience are needed. However, before using the "frog" to charge the battery, you need to navigate the markings and clearly understand which indicator is talking about what. Read more about labeling below.
Ease of use. The "frog" for charging batteries is suitable for use wherever you need it. The main condition is the presence of an outlet.
Compactness. The overall characteristics of the charger are minimal, which allows you to carry it with you in a backpack, bag or even a pocket.

What is a "frog"?

Charging "frog" outwardly looks like a small box, which in its shape resembles a frog, with an attached plug for an outlet. On the case there are two contacts in the form of antennae, designed to connect and charge lithium batteries. A feature of the device, which provides it with versatility, is that the contacts are movable. That is why you can charge batteries of various configurations.

Types of "frogs"

Depending on the type of connection, “frog” charging happens:

connected to a USB cord, and then to a PC - five-volt;
automobile - twelve-volt;
working from a standard socket - 220-volt.

The classic option is a "frog" for charging batteries, designed for a voltage of 220 volts. On the reverse side of the cover of the device there are two sliding pins, which are parallel to each other. They must be separated by a distance that corresponds to the distance between the contact areas of the lithium battery.

Universal charging "frog" has a polarity of "+" and "-". Depending on the model of the charging-clothespin, it is adjusted either in automatic mode, or manually by pressing special buttons.

Deciphering the marking

On the case, the charging “frog” is marked. Ignorance of the designations excludes the possibility of the correct operation of the charge as a whole.

"TE" - connection health indicator.

"CON" - the LED is active if the battery is connected correctly when pressing "TE".

"PW" - indicates the presence of a network connection. Can become active when the battery is fully charged.

"CH" - is in a flashing state throughout the entire time when the battery is being charged.

"FUL" indicates that the battery is fully charged.

"CO" - indicates that "+" and "-" are mixed up.

Charging "frog": how to use?

Using the frog charger is nothing complicated and supernatural, however, in order to ensure its proper and efficient functioning, it is necessary to follow the operating instructions.

How to use the "frog" to charge the battery? Step-by-step instruction is given below:

1. Turn off mobile device and remove the battery from it.

2. Open the "frog" charging by pressing the clothespin.

3. Insert into the "frog" battery so that the two terminals match. In the case when the charging device is equipped with four terminals, two side terminals are used.

4. Press the "TE" button. As a rule, it is located on the left side of the charger.

5. Check the correct connection by looking at the corresponding indicator ("CON"). It should be noted that the indicator LED may not light up not only as a result of incorrect connection of the terminals, but also due to the fact that the battery is completely discharged. If the latter option takes place, then the "frog" for charging the phone and the battery of the device are connected for about 5-7 minutes to an electrical power source - an outlet.

6. Connect to the network. Accompanied by an active "CH" indicator.

7. Disconnect the terminals after the "FUL" indicator, which is on the left, lights up.

How to check if it works

There is a verification algorithm that will help make sure that the “frog” charging is working properly. Let's see how to use it.

The key to the correct functioning of the device is the correct polarity. To check it, you must click on the button located on the left. If the lights near the "CON" and "FUL" indicators light up, the connection to the terminals is correct. Inactive indicators indicate a connection error. In this case, click on the button on the right.

Be extremely careful, because the indicator lights may not light up not only for the above reason. For example, the tablet battery will move and the pins of the clothespin will not come into contact with the pads.

If the test was successful and everything that is needed blinked, then the "frog" for charging the battery is safely connected to the outlet. “PW” and “CH” should light up. Upon completion of the charging process, the LED next to the "FUL" indicator is activated.

The total time required to fully charge the battery of a phone, camera, player, set-top box or other device from the world of technology depends on the battery capacity. On average - from 2 to 5 hours. At the same time, if it takes, say, 3 hours to fully charge the battery of your device, and the “frog” was connected to the network, for example, 5 hours, there is no reason to worry: the clothespin charger automatically stops charging the battery when the last maximum possible charge level is reached .

Do it yourself!

Making a “frog” exercise with your own hands from scratch is quite difficult and problematic, and for many it is not at all possible. But to remake from a non-universal old-style charger is quite realistic.

First, let's decide what fixtures, materials and tools should be at hand.

Source materials:

an old charger designed to charge just one model of a removable battery;
a piece of plastic;
spring from a regular clothespin;
two paper clips;
wire.

Tools:

pliers;
hacksaw;
stationery knife;
drill;
drill;
glue "Moment".

Work technology:

Voila! Miracle device done!

Such a "frog" is suitable for charging the phone of absolutely any brand, model and modification.

What is a frog for charging batteries, types, characteristics

The frog is popularly called a universal charger for charging lithium batteries. Regular charging may fail or be lost. Then the frog will come to the rescue. Most universal chargers are used to recharge phone batteries, but they can also be used to charge the batteries of cameras, players and other gadgets powered by lithium batteries. In this note, we will consider the types, device, use and some models of "frogs".

In the classic version, the frog consists of a plastic case, a plug for connecting to a 220-volt household electrical outlet, a clamp and contact terminals for connecting the battery, as well as indicators and a controller board. Due to the fact that the terminals can be installed at a certain distance, the frog can be adapted to charge batteries with different contact pads.

Somewhat earlier, when phone manufacturers released their models with individual charging connectors, if the charger (charger) was lost or broken, the owner actually lost the opportunity to use the gadget. It was necessary to repair the memory or purchase a new one. In such situation universal frog was an indispensable device that allowed you to charge almost all commercially available cell phone batteries.

Here, for example, a charger for the old cellular telephone Siemens.

Or for an ancient "clamshell" Sony Ericsson Z550i.

As a result, memory devices from phones from different manufacturers were incompatible.

In this case, the frog rescued. You just had to take the battery out of the phone, set the desired distance on the frog terminals, insert the battery and connect the device to the network.

In this case, you can easily charge batteries of different sizes and with different contact pads. Here is a Nokia BL-5C.

Or such a Samsung EB-L1F2HVU.

Connect your phone for charging or data transfer via USB port directly was not possible. It was necessary to use special adapters. Examples of such cables are shown below.

In the future, manufacturers unified their models and chargers for the USB interface. Regular chargers now have a plug for connecting to the network and a USB output.

And frogs also began to evolve. Almost everyone has got a USB interface. Contact terminals have been retained, as the population still has a lot of old cell phones in use.

Although there are more and more models equipped with only USB ports. Third-party manufacturers add additional “chips” to their devices in the form of various indicators and displays. Below you can see such a modern frog with two USB ports and a display showing the current voltage and charging current.

Recently, frogs with a USB 3.0 interface are becoming more and more common. Among them there are models that give out charging current up to 3.1 amperes.

Some manufacturers have developed real multifunctional harvesters based on frogs, which allow you to charge various batteries with customizable parameters. As a rule, they have a liquid crystal display and additional funds management.

Varieties

By design, frogs can be divided into three broad categories.

network models. They receive power through a plug inserted into a household electrical outlet. In Russia and Europe, 220 volt models are used. And also can be found in the 110 volt version, which is used in the USA.
Automotive devices. Here, instead of a power plug, a connector is installed for a car cigarette lighter socket. The charger receives power from the vehicle's on-board network.
These chargers are powered by the USB port. Similar models have almost disappeared from sale. They can be useful in cases where the phone does not have a USB interface, and you charge the battery directly in the frog. And the charging itself is connected via USB, for example, to a computer or laptop. In the event that the cell phone has a USB port, then such charging loses all meaning. In this case, the gadget is easier to connect directly to the computer.

At the output, network and car frogs have a USB interface or adjustable terminals for directly charging batteries.

To charge phone batteries directly, frogs can have terminals in the form of two elongated antennae (the classic version), as well as short terminals in a special recess in the case. The width of the terminals, depending on the contact pads of the battery, can be adjusted in both cases.

The main characteristics and their meanings are given below.

Input voltage from 100 to 240 volts, 50/60 Hz (if it is a mains charger).
Output voltage. 2 to 9 volts. This allows you to charge almost any lithium battery in modern mobile devices. Although if charging is carried out via the USB interface, then another type of rechargeable batteries may be in the device. The main thing is that the declared electrical characteristics are suitable for them.
output current. From 1 to 5.4 amps (in most cases up to 3 amps). This allows you to quickly charge the batteries of smartphones and tablets. They are not designed to charge more capacious batteries, for example, from laptops.
Dimensions. Here everything can be individual. But the vast majority of devices have a length of no more than 20 cm. The length is indicated, since this is the largest dimension of such devices.
Additional features. To stand out among others, manufacturers equip their models with battery indicators, as well as information displays. In most cases, such chips are not necessary, and they should be chosen depending on the desire and financial capabilities.

A frog is a simple, but very useful device in everyday life. It can charge lithium batteries push-button phones, smartphones, camcorders and digital cameras regardless of their shape. Frogs are inexpensive (especially Chinese models) and are very widespread in Russia.

Maintenance

What is a frog

The frog (or "toad" - as these devices are also called) is easy to recognize by two springy wires on the top cover, which are bred to the sides to the desired distance - thanks to this they can be docked with various batteries.

It is these contacts that should be connected to the battery, previously pulled out of the phone. That is, the device is only suitable for removable batteries (which means that this device is useless for owners of the iPhone and many other modern models from other manufacturers).

The frog is capable of maximum in a simple way transfer energy to lithium batteries. At the same time, in some cases, it can charge even faster than the charging that comes with the kit.

Types of universal chargers for phones

Now in stores you can find the following options for universal chargers:

automotive (attached to the cigarette lighter);
with a USB port (has a corresponding USB connector);
with household power plug (standard).

In addition, models have recently appeared on the market that simultaneously have both a USB port and a plug.

Also, all modern frogs can be divided into automatic and semi-automatic. The main difference between the first and second type is the number of LEDs: the “automatic” has three of them, the “semiautomatic” has four. The fact is that automatic models are able to independently determine the polarity, and therefore the polarity reversal button (usually it goes under the designation CO) is absent on them.

Frog charger circuit

The concept of a classic frog is quite simple. Two moving contacts connected to the battery come from the controller. The role of the controller is performed by microcircuits of a certain complexity. The task of the controller, in particular, is to compare the voltage on the battery with the internal reference. When these two indicators become identical, the controller will turn off the power supply.

Another significant detail of universal charging is a bridge AC / DC converter with a built-in key for connecting the battery to a power source (mains). It is located at the very beginning, before the controller and contacts. The purpose of this node is to transform AC voltage into permanent.

Theoretically, the frog can be used with the same intensity as regular exercise. But in practice, it often acts as a backup charger. If the original memory is lost, then universal charging will allow you to stay in touch.

Sometimes, after losing the charger that came with the kit, it turns out that it is very difficult to find the right analogue. This is true primarily for old models of mobile phones that are no longer produced, but remain in use. A frog in this case can save the situation. And if for some reason the battery connector is broken, the toad can also help out.

Universal charging will certainly come in handy for those who have two or more phones different models. Going on a trip, you can not take a bunch of power supplies with you, but get by with this one device.

Important! It is the frog that is used “to bring back to life” completely discharged lithium batteries in mobile devices. The universal charger controller is not able to block the supply of voltage to a deeply discharged battery, and in this particular case this is an advantage, not a disadvantage.

How the frog charger works

One of the clear advantages this device- small dimensions. This allows you to easily carry it in a backpack, bag or pocket and plug it into any suitable outlet. The classic frog is powered by 110-220 volts. In this case, the output voltage is much less (for example, 4.2 Volts). As for the strength of the output current, it is equal to several hundred milliamps.

The charge occurs in the device automatically and is controlled by a microcircuit. When the maximum possible charge level is reached, the device turns itself off. That is, nothing terrible will happen if, instead of the required three hours, the battery is in universal charging for a couple of hours longer. In general, the time to fully charge the battery (digital camera, smartphone, player, and so on) depends on the capacity. As a rule, we are talking about a period of 1.5 to 5 hours.

How to use the frog to charge the battery

Of course, such a device as a frog is accompanied by instructions from the manufacturer. But it is often written in a foreign language (in particular, in Chinese), and therefore the user has to figure it out on his own.

The battery must be inserted into the frog so that the contacts of the universal charger are located on the plus and minus terminals of the battery. If there are three or four terminals on the battery, the two most extreme of them should be used.

If the polarity has been chosen correctly, then when the TE (test) button is pressed, the green LED CON will light up. After that, you can safely insert the entire structure into the outlet. As a result, the PW (network) indicator should light up, and then the CH (Charge) indicator should light up. And when charging is complete, the corresponding FUL LED (full charge) will light up.

If the CON diode does not want to light up, then most likely you have a very dead battery in front of you. A battery with a nominal voltage of 3.6 Volts may well be discharged below 3.2 Volts, and in such a situation, the mobile phone will not show any signs of life even when the “native” charger is connected.

The solution is simple: the battery must be arbitrarily, in any polarity, connected to the frog and plugged into the network for five minutes - the CH diode should blink. The task of universal charging is to give a strong boost to the battery charge. And then it can already be charged in the usual way.

Attention! Sometimes, with a damaged battery, the frog may show a full FUL charge, even if this is not true. It is unlikely that you will be able to fix this on your own - you need to call a professional master or simply throw out the battery.

Precautions

Always insert the lithium battery between the contacts first. And only then the device can be inserted into the socket. If you act the other way around, you can get a noticeable electric shock.
There must be no flammable materials near the universal charger plugged into the socket.
The frog is designed for lithium batteries only and therefore should not be used to charge other types of batteries.
After the battery is charged, it is advisable to remove the universal device from the network.

Remaining questions about frog or have something to add? Then write us about it in the comments, this will make the material more useful, complete and accurate.

The technical devices of the new generation amaze with their diversity. For example, have you ever thought that there are so many cords for charging various devices that there are not enough fingers to count? And each device needs only its own charge. But there are also universal chargers that can charge any piece of equipment, be it a phone or a camera. This article will consider the universal charging "frog".
