How to use a frog to charge a battery. Frog for charging batteries of mobile devices

There are situations when the charger that comes with the device stops working or the battery is so discharged that it needs to be “overclocked” for normal operation.

In this case, a universal “frog” charger will help. It is suitable not only for a phone, but also for video cameras, GPS navigators and cameras, the main condition is that the battery is lithium.

Also, its capacity should not exceed 2000 mAh, current – 200 mA, voltage – 3.5-4.8 W.

There are three types of frogs:

standard, powered by 220 V;
automotive, powered by 12 V;
computer, powered from a 5 V USB port.

They also come in automatic and semi-automatic versions. The main difference is that the former have three indicator lights, while the latter have four.

How to use a frog to charge your battery

There is nothing complicated about connecting a dead battery to a frog. First you need to find out what the indicators located at the bottom of the charger mean. So, let's look at each of them:

TE – testing for correct connection;
CON – turns on after the TE indicator if connected correctly;
PW – lights up when connected to the network;
CH – flashes during charging;
FUL – means that the battery is 100% charged;
CO – must be pressed if it is necessary to change the polarity if testing reveals a connection problem.

Now that we know the purpose of the buttons and the designations of the indicators, let's proceed directly to charging the battery. We take the battery out of the device and connect its contacts to the frog contacts.

It doesn’t matter which way you connect, because the polarity is determined automatically. If the “plus” and “minus” coincide, the CON (connection) indicator will light up. We insert the “toad” into the socket, and after an hour and a half the LED under the FUL inscription should light up.

The degree of charge is determined by a microchip. Although some claim that the device turns off when fully charged, it is still better to keep an eye on the process: the device is Chinese - a fire may occur if connected to the network for a long time.

For safety reasons, it is better to keep a plugged-in frog away from flammable materials.

Problems and solutions

As you can see, everything is quite simple, but some difficulties and unforeseen situations may arise.

After testing, none of the indicators came on. In this case, press the CO button. Did not help? Then you, apparently, made a mistake with the contacts, because there may be four of them on the battery, but you only need two - “+” and “−”. If even after the rearrangement no changes are observed, then either the charger has failed or the battery is no longer working.
It also happens that the phone has not been used for a long time, and you suddenly remembered it. The battery charge has already been completely depleted, for this reason the indicators will not light up. And then you should insert the frog into the outlet for a short period of time, no more than 10 minutes. After this, you can charge the battery through your phone.
When connected to the network, the FUL indicator may light up immediately. This means that the battery is no longer working.
Another indicator of inoperability is fast recharging (5-10 minutes);
The simultaneous lighting of the PW and FUL diodes indicates that the device is not in contact with the battery. You need to check the connection.

That's probably all that could be said about how to use a frog to charge a battery.

We can only add that the device is easily available in the markets and is inexpensive (about 200 rubles), so if for some reason you cannot charge your device in the standard way, purchase a universal Chinese charger.

Dear readers, today we will look at the question of how to charge a phone battery with a “frog”. But first of all, you should learn a little more about the device itself, which can often help the user with its versatility. In the next block, we will look at devices that can be charged in this way.

So, a universal charger for phones (and not only: you can charge a huge list of devices that you can choose yourself by analyzing the information received), which is called a “frog”, allows you to easily increase the amount of energy in the battery. It is very convenient to take it with you on hikes: if there are several people in the company, and one of them has forgotten the charger, then the “toad,” as it is also popularly called, can greatly help out your friend. The versatility of this miracle lies in the fact that only the battery removed from the device is used for recharging. In this regard, the list of supported models is somewhat reduced.

What devices can be charged

Slowly but surely we are getting to phones that can be charged this way. As noted above, to use this design you will need to remove the battery from your smartphone. Based on this, we can conclude that you cannot charge an iPhone, some Samsung models, and so on with a frog. That is, devices with a non-removable battery are subject to restrictions. For greater convenience in assessing whether a “frog” is suitable for you as a charger, let’s look at its parameters:

You can charge Li-Ion batteries with a capacity of up to 2000 mAh
The rated voltage of the connected battery should be between 3.5 and 4.8 V
The network voltage should be between 110 and 220 V
The output voltage is 4.25V and the current is 200mAh
The average standard charging time for one battery is one and a half hours

So, now you can independently see the parameters of your battery and compare its characteristics with those indicated above. For example, if your phone’s battery has a capacity of 2300 mAh, then it definitely cannot be frog charged. But be sure to check the performance of your universal charger, because the information presented above is valid for the standard version. If you are ready to take action, then move on to the next block.

Conclusion

Dear friends, now you know how to charge your phone battery with a frog. If your device is not suitable, then do not be upset. If everything worked out, then we are very happy for you and hope that you were able to charge the battery of your mobile or any other device. Tell us in the comments how the “frog” helped you out and in what situations. Enjoy using this little “swamp” miracle!

This method is usually used for emergencies, but you need to be prepared for anything.

The frog charger is designed for charging. Visually, it is a compact unit, on one side of which there is a plug for the socket, on the other - a slot for the battery in the form of a contact clip. The terminals connecting the frog to the battery are movable, so almost any removable battery can be charged in this way.

The charger in most cases has an indication that will show whether the battery is connected to the frog correctly. If the contacts are connected correctly, the battery will begin charging. If not, the corresponding indicator will light up. As a rule, the main reason for the lack of charging is reversed polarity.

What devices can be charged with a frog?

Of course, such a charger cannot be used if the battery is integrated into the smartphone body. Many budget models do not charge batteries larger than 2000 mAh. Typically, information about capacity, specifications, and limitations can be found on the case or in the documentation.

A frog charger will also be needed by those who have purchased rare phone models or Chinese analogues of branded gadgets. They may be equipped with non-standard charging connectors or other complications, which will make it difficult to find an AC adapter in the event of a breakdown or loss of the original accessory from the kit. In this case, frog charging will help.

You can also charge:

camera or video camera battery;
battery from a remote controlled car;
Walkie-talkie battery;
and almost any lithium battery.

This method also has two significant drawbacks. Firstly, the battery will have to be removed from the phone while it is powered, which means you won’t be able to use it until the required battery charge level is reached. Secondly, the charging process is usually much slower than from.

How to use frog charging?

First of all, you should turn off the gadget and remove the battery. The terminals of a discharged battery must be clamped with the corresponding antennae on the charger body. Now it can be connected to the network. If the indicator lights up green, the battery is connected correctly.

The time it takes to replenish the battery varies depending on the battery charge level and capacity. On average, the “frog” charges the battery of a smartphone in 2-3 hours.

How to use a frog to overclock a battery?

In addition to the functions described above, frog charging sometimes helps to jump-start non-working batteries. If the device has been discharged for a long time, then there is a possibility that it will not be possible to revive it with regular charging.

If the battery is working, but shows a voltage of 0 V, you need to connect it to our accessory for 20-30 minutes. After this, you can move the battery into the device and recharge it with regular charging.

The simplest solution to the situation when the battery of your favorite gadget is low and the charger is out of order is to buy a “frog” (toad) at the nearest electronics store, which will successfully replace a standard charger (charger).

What is a "frog"

“Frog” belongs to the category of universal chargers. A universal battery charger capable of charging a range of models with removable power supplies: from mobile phones and cameras to navigators and tablet computers. Before use, please read a number of restrictions:

The battery being charged must be lithium type(the device will not cope with other varieties and may even fail);
volume should not exceed 2000 mAh;
nominal voltage from 3.5 V to 4.8 V;
voltage online from 110 V to 220 V;
day off voltage 4.25 V, current - 200 mAh;
charging time no more than 1.5 hours.

It is difficult to say specifically how much a “frog” costs to charge the battery of phones, tablets and other equipment. Depending on the model, prices can vary from 100 to 600 rubles.

What is the advantage of the device

Universal multi charger (English name for “frogs”) enjoys customer loyalty for a reason. Let us briefly list the main “advantages” of the device:

used for charging voltage sources for various small-sized equipment;
saves significantly user funds, eliminating the need to purchase a separate charger for each device;
small sizes provide portability (ease of movement) of the device;
technically easy to use.

How the device works

Externally, the device actually looks a bit like the amphibian of the same name: the body, made of plastic, has a characteristic rounded-elongated shape. At the top of the device there is a battery holder equipped with a contact group responsible for recharging the battery. Depending on the model, the device may be equipped with electronic screen, which will display technical parameters. LED indicators with corresponding inscriptions can play the same role.

Types of device

Depending on the type of connection, the following types of universal chargers are distinguished:

Classical network version, operating from a standard 220 V outlet.
memory for auto from 12 to 24 V. Equipped with an adapter for a cigarette lighter.
Device with the ability charge via USB port, connected to a computer. Input voltage 5 Volts.

All of the above modifications are successfully used to replenish power for a wide range of electronic devices with Li-Ion batteries. Unable to charge“frog” are only those gadgets in which batteries are an integral part of the design (Apple iPhone and some of the Android, Windows Phone, Symbian models).

How to decipher the markings

The presence of LCD screens, which display all the information about the battery charging process, greatly facilitates the operation of the device. However, these devices are significantly more expensive than their budget “brothers”, which use a simple display system to alert the user:

Indicator nutritionPW– constant green light. Signals that the device is connected to the network.
Indicator charging the battery CH– flashing green light. Notifies you about the start of the power replenishment process.
Light bulb with markedFULL warns that the battery is fully charged.

How to use the Frog to charge the battery

Using the “frog” to charge batteries is not difficult; you just need to follow a few simple steps:

Disable device you plan to charge and carefully remove the battery from it.
Open the memory by pressing the “clothespin” lever.
Place battery under clamp, combining its contacts with the “frog” terminals. If the battery has more than two contacts, use the pair located closer to the edge.
Connect device to an appropriate power source.
After charging is complete install the battery to the right place. Check the power level on the screen.

Checking functionality

On the side surface of the classic “frog” type there is a button marked inscription TE, i.e. "testing". It is used to check the polarity of the connected battery. Pressing this button once turns on the CON diode to turn green, confirming that everything was done correctly.

If the light bulb CONdoesn't light up− press the button on the right, which changes the polarity.

If no buttons are found on the side panels of the device, most likely the model tests polarity automatically.

Also, the indicators may not light up if the battery has moved to the side and its contacts no longer interact with the charger terminals.

DIY "frog"

It’s quite possible to make a primitive universal “frog” type charger for a phone on your own; for this you will need:

We perform the following manipulations in turn:

Bite off with pliers the heads of the pins and drive the points into the plank base.
Loose ends of pins fold up.
Expose the wires charger. Clean the contacts from braid residues.
Solder the wires A charger with the “frames” of pins sticking out of the plywood.
Fill the resulting structure with glue
Flush with contact pad fix with glue clothespin.
Unclench the clothespin and insert the phone battery into it, attaching the ends of the pins to the battery contacts.

We charge for a couple of hours, after which we check the battery for fullness.

Also, you can solder such a device yourself, focusing on the frog circuit for charging the battery below, but this requires specialized knowledge.

Malfunctions and solutions

Here are several typical malfunctions typical of universal chargers, and we will offer solutions to the problem:

Indicator CON is off, although everything was done correctly. Most likely, the battery is completely discharged. In this case, you can try to boost it using a laboratory power supply.
Doesn't light up bulbPW– the fuse may have blown and should be replaced.
Absent output voltage– there is a high probability that the capacitors in the device microcircuit are “broken.”
The device turns on normally, but after a few seconds " goes out"- a device is activated that protects the frog from overload. The load circuit needs to be tested.

If used carefully, this useful device will last a long time. Put it in your backpack or handbag and be sure that it will certainly be useful at the right time.

Content:

Recently, manufacturers of various electronic gadgets have almost all come to a common connector for charging and transferring data to a computer or other device. But just recently, each brand, and sometimes model of phone or digital camera had its own special plugs. Such devices still work successfully for almost half of the population.

And then the moment comes when the charger has become unusable, or where the person is there is no necessary connector, but the phone needs to be charged. Just for such a case, there is a universal charger, popularly called a “frog”.

Now let’s try to understand what kind of battery charger this is, how it can charge various batteries, what advantages, or perhaps, on the contrary, disadvantages it has over conventional switching power supplies and in what cases it can be used.

What is charging?

In appearance, the “frog” charger is a small box, on one side of which there is a plug for an outlet, and on the other side there are two contacts under transparent plastic on a spring.

This universal charger is intended for mobile phone batteries, and indeed for any lithium batteries whose capacity does not exceed 2000 mAh, current strength - 200 mA, and the voltage at which the battery is charged should be in the range from 3.5 to 4.8 V.

The most interesting thing is that when purchasing a frog, several adapters are included with it. Therefore, among them there may be the necessary plug. If this does not happen, then to charge the battery you will have to remove it from the device.

Moreover, the undoubted advantage of such a device is the presence of its own battery, which will allow you to recharge the battery where there is no electricity. Maybe not completely, but still...

So how does it happen that the contacts of a “frog” telephone charger are suitable for any batteries, and now we’ll try to figure out how to use such a device.

How to use the device?

The battery is connected using two contact plates on springs, which are adjustable in width. That is why you can choose the required size between the contacts. Regardless of how many terminals there are on the battery, the last two usually work when charging. Just in case, you can look at the battery itself - opposite the necessary contacts there are always “+” and “-” icons.

After installing the battery in the frog charger, you need to press the “TE” (test) button. If the green indicator (“CON”) lights up, this indicates the correct polarity of the connection. If this does not happen, you need to change the polarity by simply pressing the “CO” key. There are models without a polarity change button. In such devices it changes automatically as needed.

After this, you can plug the universal charger into a power outlet. At the same time, the “PW” lamp (network presence) should light up on the panel, and the “CH” LED should blink. After about an hour and a half (some batteries can take up to 5 hours to charge), the “FUL” indicator lights up, indicating that the battery is fully charged.

Although the instructions state that you don’t have to unplug the charger from the outlet after charging the battery, it’s still worth doing. After all, all the “frogs” are made in China, which means the quality of such devices leaves much to be desired.

Some features

Sometimes there are situations in which you cannot do without such a universal charger. For example, after the battery was completely discharged, the phone remained unused for some time. In this case, if the battery charge drops below the level specified in the gadget’s program, the device simply will not perceive the battery as a power supply. In this case, it will not be possible to charge it with a standard device. That’s when a similar “frog” for your phone comes in handy. Moreover, if the battery is completely discharged, the “CON” light will not light up during testing.

The way out of such a situation is this. Ignoring the polarity, since it’s impossible to check it anyway, the “frog” with the battery is plugged into the network for 5 minutes. And after 5 minutes of such charging, the polarity is checked again with the “test” button.

Varieties of "frogs"

In general, such battery charging devices are not recommended to be used very often, because... in their essence they are shock, i.e. The battery is charged from them in an emergency, accelerated manner, which means that with constant use it will quickly become unusable.

There are 3 types of “frogs” (they are also called “toads” and “clothespins”), namely:

For use in the car. This device has a cord with a plug that fits into the cigarette lighter socket. A convenient option for emergency phone discharge on the road.
Phone battery charger, powered by 220 V. The standard and most common type of “clothespin”.
Frog for charging at 5 V. A charger that has a USB plug instead of a 220 V plug. Such “toads” have the smallest size of all in this line. They can be worn on keys instead of a key fob.

Some nuances

It happens that such a charger for a phone battery does not behave as expected. And there are reasons for this. It has already been written about the complete discharge of the battery, but what should you do if the full charge light immediately comes on on a discharged battery? In this case, you can throw away the battery, because this indicates that it has fallen into disrepair. A quick, full charge within 10–15 minutes can also indicate problems with the battery.

If the “FUL” and “PW” indicators light up at the same time, this indicates poor contact between the device and the battery.

That's probably all that can be said about this universal charger.
