Frog without buttons how to charge. Universal charger "frog" with USB port

How to use the frog to charge the battery

FUL- the battery is fully charged

SO- polarity reversal if + and - are reversed

Now I'll tell you how to do everything right, what would Charger(toad) started charging your battery.

We throw the battery with a plus and a minus to the two contacts of the toad (no matter how). There may be more than two contacts on a battery, but only two are needed (+ and -). Then press the left button THOSE, if + and - match, it will light up CON(first LED).

Also, if the battery is charged, it may light up. FUL and will always burn PW.

If the battery is low, pressing THOSE will only burn CON. In this case, plug it into the socket and it will start flashing CH. Waiting for it to light up FUL(not less than 1 hour), then everything - the battery is charged.

In the case when you connected the battery to the charger, press THOSE and nothing lit up, you need to press the right button SO, then it should work. If nothing lights up anyway, then the battery is not connected to the frog with a plus and a minus, or the charger is faulty or the battery is faulty. It may also be an option that the battery is as discharged as possible (to zero), then plug it into a socket, it should flash CH if not, press SO. If still nothing happened, then read above.

No need to exclude options for various glitches, all the same, a Chinese work 😆

"Frog" for charging batteries: how to use it

If the mobile phone is discharged, and there is no native charger at hand, you should not despair. In such a situation, a “frog” for charging batteries will be a real find. Its main advantage is versatility, ease of use, prevalence and low cost. It is suitable for batteries with different connectors. Consider the principle of operation and the rules for using the frog.

General information about the device

A frog is a simple device designed to charge the batteries of mobile phones of various models and manufacturers. Read more about how to charge your phone battery without a phone →

In addition, the “toad” can charge a lithium battery from cameras and other small-sized equipment.

Outwardly, it looks simple and is a plastic box with a plug on one side and a special clip for contact with the battery on the other side. The “toad” design allows it to be used for batteries with connectors of different sizes due to the movable contact terminals.

The universal fixture does not require any special technical knowledge or skills. To use the frog, there is no need to think about how to properly insert the battery into it. She herself will determine its polarity.

Varieties of universal chargers

To date, on sale you can find several varieties of devices of this type, designed for lithium batteries. mobile phones and other small-sized equipment, different in terms of power source:

from car cigarette lighter;
from USB port;
from an electrical outlet.

Also, universal charging can be automatic and semi-automatic. The main difference is in the number of indicator lights. Automatics have three, and semi-automatics have four. The automatic "toad" itself will determine the correct polarity, and for the semi-automatic, additional control of the correct connection using the buttons will be required.

How to use the "frog"?

How to use universal device? The algorithm for its application is simple and the same for everyone. You can charge a lithium battery of a phone, camera, camera, navigator with a frog, provided that it has the following characteristics:

capacity not more than 2000 mAh;
current 200 mA;
output voltage 3.5-4.6 V .

It will not work to charge the battery with a frog if it does not meet these characteristics.

First, the battery must be disconnected from the technical device. Then it is installed in the "frog" so that the terminals (+ and -) coincide with the contacts of the device. Most chargers of this type have up to 4 terminals, but, as a rule, two extreme ones are used.

The next step is to check the polarity if the model is semi-automatic. To do this, click on the Te button (it is located on the left). If the green indicator lights up, the battery is connected correctly. If the connection is wrong, use the polarity change button CO (located on the right), and then again TE. In the automatic model, the polarity itself does not need to be determined.

During operation, the PW and CH mains indicator will be active, and at the end of the process, FUL, indicating that the battery can be used further. After 2.5-5 hours after placing the battery in the device (the time depends on the battery model), it can be removed. It is fully charged and ready for use.

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".

"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 under consideration is suitable for all batteries of mobile phones, cameras, camcorders, PDAs, MP3 players and other small-sized equipment that operates using 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 charger-clothespin, it is adjusted either automatically 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 in case correct connection battery by 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 the mobile device and remove the battery from it.

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

3. Insert the battery into the "frog" 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.

General information about the device

A frog is a simple device designed to charge the batteries of mobile phones of various models and manufacturers.

In addition, the "toad" can be from cameras and other small-sized equipment.

Varieties of universal chargers

To date, on sale you can find several varieties of devices of this type, designed for lithium batteries of mobile phones and other small-sized equipment, different in power source:

from car cigarette lighter ;
from USB port;
from an electrical outlet .

How to use the "frog"?

How to use the universal device? Its algorithm The application is simple and the same for everyone. Can frog charge phone lithium battery , camera, camera, navigator, provided that it has the following characteristics:

capacity not more than 2000 mAh ;
current 200 mA;
output voltage 3.5-4.6 V .

It will not work to charge the battery with a frog if it does not meet these characteristics.

Important! The frog is only suitable for charging lithium batteries. Batteries of a different type, after an attempt to restore them with a “toad”, will become unsuitable for further operation.

What to do in an unusual situation

When using a universal charger, atypical situations may occur, for example, the battery is charged too quickly or the indicators are not backlit.

How to charge the battery of cellular terminals if no indicator of the working device lights up? In such a situation, it is recommended to press the CO button.

If nothing changes after that, most likely:

there is an error with the contacts, you need to change the polarity ;
Battery not working ;
"toad" is broken .

The device will help in a situation where the phone's battery is completely dead and has not been used for a long time. In this case, it must be placed in the frog for 10 minutes, and then charged with the native device of the terminal.

If, during operation, the device signals a full charge 10-15 minutes after connection, then it is out of order. And the FUL indicator, active when connected to the network, indicates the unsuitability of the battery.

If the FUL and PW indicator lights up at the same time, then there is no contact between the charger and the battery.

"Toad" can be easily bought in online stores, it is inexpensive. This makes it even more attractive to users. It is extremely simple, so if necessary, you can do it yourself from improvised materials. To make it, you will need a clothespin, unnecessary charging from any phone, a few pins, a wooden block, pliers, a glue gun and a soldering iron.

A clothespin is attached to the bar using superglue or a glue gun. Two pins are placed next to each other at a distance of 0.5 cm. The ears of the pins must be removed, and the tip should be driven into the piece of wood by half a centimeter. The end of the pin where the eye was located is slightly bent forward. The plug cut off from charging is attached to the pins, having previously determined the plus and minus. It is advisable to mark the polarity on the board so that later there are no difficulties with this. The fastening of pins and wires should also be strengthened with glue so that they do not loosen during operation. When using such a frog, the battery is connected to pins (homemade contacts) and fixed with a clothespin.

There are a lot of descriptions of this process and video tutorials on the network, making it will not be difficult. It will really help out in situations where it is impossible to use "native" charging for small equipment for some reason.

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 convert AC voltage to DC.

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 of 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 “return to life” completely discharged lithium batteries. 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.

Dear readers, today we will discuss the question of how to charge a battery from a phone with a “frog”. But first of all, you should learn a little more about the device itself, which can often help the user out with its versatility. In the next block, we will consider 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 yourself can pick up by analyzing the information received), which is called a “frog”, allows you to increase the amount of energy in the battery in a simple way. 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 their exercises, then the “toad”, as it is also called by the people, 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.

To learn how to use universal charging - just read our new article

What devices can be charged

Slowly but surely, we got to phones that can be charged in 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 it is impossible to charge the iPhone with a “frog”, some Samsung models, and so on. That is, devices with a non-removable battery fall under the restriction. For greater convenience in assessing whether the “frog” is suitable for you as a charge, let's look at its parameters:

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

So, now you can independently look at 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 charged with a “frog”. But be sure to check the performance of your universal charger, because the above information is for the standard version. If you are ready to take action, then move on to the next block.
