How to choose a charger for a car battery. How battery chargers work and how they work
Probably everyone has at least once encountered a problem when the charger that came with a smartphone or tablet died for a long time. And so you have to go to the store to find a replacement for it. But, having bought a new charger, it suddenly becomes noticeable that with it your multi-core pet takes much longer to charge than with the original one. Or it doesn’t charge at all, but just works from the network. In fact, this problem is quite easy to avoid. How? We'll tell you below.
If you believe the stories of former employees of official retail, then such products can even be purchased at Euroset or other well-known chains. And if you buy a charger at Gorbushka or Savelovsky, and even more so on Aliexpress, then you should be especially vigilant. Unfortunately, Aliexpress cannot be checked here. But you can test the charger that you plan to purchase in your hometown. And it’s necessary, because it’s no secret that the lion’s share of chargers that are sold in stores are ordered from Aliexpress and sold to you at a premium.
The most common problem with them is when the charger does not produce enough current to charge your smartphone; the device consumes more than it can receive from the network.
How to choose a high-quality charger for your smartphone?
- Buy original products. For example, if you have a Xiaomi or Samsung smartphone, then it is better to go to the company’s showroom and purchase a charger there. Thus, you will receive an original charger, which, by the way, will correctly and safely support various Quick Charge-type features.
- Test the product before purchasing. Ask to insert the charger into the socket and check it with special software. For example, using the Ampere app .
- In some cases, you can even determine by weight which of the two charger power supplies is better. If it weighs too little, it will most likely produce minimal current and charge your gadgets extremely slowly.
- Pay attention to logos and inscriptions. They must be applied evenly and accurately, all inscriptions must be easy to read, and the fonts must not be smeared. These are clear signs of counterfeit goods.
- A high-quality charger today cannot be cheap. We were unable to find a high-quality copy with a price of up to 500 rubles. From 500 and above, and even if you bargain, there are chances.
By the way, do not forget that the charging speed will also depend on the wire. It should at least be free of defects to get normal results.
Comparison of Noname and original chargers
We purchased and tested some not the most expensive (up to 500 rubles) and often found at retail outlets mobile chargers. Nothing exploded or burned, which is not bad. But the results of the battery charging process were disappointing.
The chargers in the title photo of the article turned out to be one of the slowest. When connected to the network, the smartphone simply did not discharge, but charging it in this way is almost impossible if at least the screen is turned on. With such a charger, the device should be left alone to reduce energy consumption. Ideally, charge it off or in airplane mode.
The second type of charger is similar to the one in the picture above. By the way, they often say “Samsung” on them, but in reality this is not the case. If you put such a charge next to the original one, you can easily notice the difference in the fonts, as we wrote above.
Testing was carried out on a tablet.
So, several Noname chargers and fake Samsung ones gave the following results:
The last result was all right.
And now the result of regular proprietary charging from HTC, without Quick Charge support.
As well as the numbers produced by the Xiaomi branded charger with Quick Charge support.
You should not be 100% attached to these results, since there are many factors that can cause measurement errors. Including the device model, installed OS, number of running processes, etc. However, now, when choosing a charger in a store, you can focus on these numbers at least approximately.

When choosing a charger, you should first pay attention to the electrical characteristics of the power supply.
How to choose a phone charger: what to look for
The main criteria when choosing a charger are:
Type (standard adapter or external “power bank”);
Electrical characteristics (voltage, charging current, power);
Support for fast charging technologies (Quick Charge, Fast Charge, etc.);
The number of cable connectors and the voltage of each of them.
The manufacturer of the charger is also important.
Types of chargers
Structurally and according to the principle of operation, chargers are divided into two types - adapters themselves, they are also power supplies; and external chargers, better known as “power banks”.
Adapters or power supplies
Adapters are structurally conventional electrical converters that rectify and reduce voltage. Such devices are intended for charging a phone or smartphone from a household network. According to the results of the conversion, alternating current with a voltage of 220 V and a power of 5-6 A is “transformed” into direct current, whose parameters are 5-18 V and 0.5-2.1 A, depending on the characteristics and purpose of the adapter.
Adapters are made in the form of small blocks that are installed in a household outlet. A power cable is connected to them, through which the converted electric current is “transmitted” to the smartphone.
Structurally, adapters are divided into household adapters, intended for installation in a regular outlet, and automobile adapters, powered from a cigarette lighter or a corresponding socket. Despite the similar principle of operation, they are not interchangeable.
The main criteria when choosing an adapter are the parameters input voltage, output voltage, current and support for fast charging technologies.
It is worth mentioning separately another type of power supply – wireless chargers. Such devices recharge the smartphone that comes into contact with them. Of course, the smartphone itself must support wireless charging.
External batteries or power banks
External batteries, which can also be called portable chargers, power banks, etc., have the same operational purpose as power supplies - they are used to charge a smartphone. However, the operating principles of these devices are radically different.
The power bank is a high-capacity battery by design. It is complemented by various functional elements - charge controller, LED indicators, power connectors, buttons, etc. The operating principle of a power bank is as follows:
First, the external battery is charged from a power source (for example, from an adapter or computer via a USB cable);
Then it “holds” the accumulated energy for some time;
When you connect a smartphone, the power bank releases accumulated energy to the connected device.
Essentially, the power bank is designed for emergency charging of a smartphone in conditions where it is impossible to get to an outlet or there is no time for it - when traveling, for example.
When choosing a power bank, you should take into account the following criteria: capacity, charge current, case material, support for fast charging technologies.
Main selection criteria
When choosing a charger, you should pay attention to the following parameters:
Input current and socket standard (especially important when ordering from foreign online stores);
Charge current;
Charge voltage;
All these parameters determine the compatibility of the charger and smartphone.
Input current and socket standard
Russian household electrical networks use a current with a voltage of 220 V, a power of 5-6 A (however, when connecting high-power equipment such as kitchen appliances, this parameter increases significantly up to 18-19 A) and a frequency of 50-60 Hz. These are the parameters that must be supported by the charger.
At the same time, in the USA, household networks are used, in which the voltage is 110 V. An adapter intended for use in America may simply burn out in a Russian “outlet”.
As a result, when ordering a charger in any online stores, you should first of all pay attention to the supported input voltage. Some adapters can work on any network.
It is also worth considering that sockets vary from country to country. In Russia, type C connectors are used. In “our” sockets you can install Europlug, Schuko, CEE 7/7, CEE 7/16 or CEE 7/17 plugs.
But types A and B (NEMA standards), used in the USA and Canada, are not suitable for use with Russian outlets without the appropriate adapters.
Charge current
The charging speed of the smartphone directly depends on the strength of the charging current. The higher it is, the faster the device will restore the energy reserves in the battery. At the same time, it is worth remembering that older smartphones are simply not designed for high charging currents.
But a low charging current can lead to the fact that the smartphone will not charge at all - it will simply discharge, even when connected to the network. The standards for this parameter are:
500 mA (0.5 A). Suitable for use with mobile phones or very old smartphones. Such a charging current is not capable of covering the “fixed costs” of a modern high-power mobile device, but is necessary and sufficient for devices manufactured, for example, before 2010-2011;
750 mA (0.75 A). Very rare. The scope of application is similar to chargers designed for 0.5 A;
1000 mA (1 A). The most common current standard in chargers today. Quite versatile, suitable for use with most mobile devices - from mobile phones or portable players to smartphones in the budget or mid-price segments;
2000-21000 mA (2-2.1 A). Used for resource-intensive devices - for example, tablets or flagship smartphones with a high-resolution screen and a powerful processor. May be dangerous for older devices. Provides high charging speed and stable power even during active use of the connected device.
It is advisable to use power supplies that have the same current strength as those supplied with the smartphone. This, however, does not apply to adapters that support fast charging technology.
It is worth remembering that manufacturers of budget power supplies often deliberately overestimate the output current. For example, a device that is labeled as 1 A may actually output 0.5 A. Therefore, the quality of the power supply is also quite important.
Charge voltage
Almost all modern smartphones, unless otherwise specified, are designed to be powered by a charging current of 5 V. This standard is used, for example, in computer USB ports. As a result, for a smartphone to be compatible with a PC, it must receive a 5-volt current.
Therefore, you should definitely not purchase chargers or power supplies that have a supply voltage greater or less than 5 Volts. Such accessories may well “burn” the delicate electronics inside the smartphone or damage the built-in battery.
Likewise, this rule does not apply to adapters that support one or another fast charging technology.
Since 2014-2015, many manufacturers began to introduce fast charging technologies. With such a connection, the power supply produces high current and voltage values in order to restore the battery capacity of the smartphone even faster. The specific value of these electrical parameters is determined by the manufacturer and the fast charging technology standard, but in general is up to 5 A and up to 20 V, respectively.
Fast charging technology is implemented at a low software and hardware level and involves the exchange of not only electricity but also information between the smartphone and the power supply. For example, the power controller in a smartphone sends a “command” to the power supply to increase the current and voltage, and it, accordingly, executes it. Or not, if it does not support fast charging technology.
It is clear that if you connect a smartphone that does not implement it to a power supply that supports fast charging technology, the latter will receive less current.
However, fast charging standards vary. The following are distinguished:
Quick Charge. A standard developed by Qualcomm and supported only by a limited number of SoC processors from this manufacturer;
Pump Express. Standard developed by MediaTek. Similar to Quick Charge, supported only by a limited number of SoC processors from this manufacturer (installed in most Chinese flagship smartphones);
TurboPower. The standard was developed by Lenovo specifically for some Motorola smartphones;
Adaptive Fast Charging. Samsung proprietary charging standard. It has been used since 2015 in smartphones of the flagship and “upper-mid” price segments - in the S, Note, A and some others lines;
VOOC Fast Charging – developed by BBK specifically for OPPO smartphones;
Dash Charge – developed by OnePlus for branded smartphones;
Super Charge – Huawei standard;
Super mCharge is Meizu standard.
Standards are not cross-compatible in most cases. Therefore, if your smartphone supports Samsung Fast Charging technology, you should purchase a power supply for it that supports the same technology. But the Quick Charge adapter will only “produce” standard 5V/2A.
How to choose an external charger
When choosing a power bank, you should pay attention to three parameters:
-
Charge current;
Case material.
But the first two are the most important.
Capacity
The higher the capacity of the power bank, the more times it can recharge a dead smartphone. However, the actual value of this number is determined by the battery capacity of the smartphone.
For example, if the smartphone is equipped with a 3000 mAh battery:
A 5000 mAh power bank will recharge it once;
A 10,000 mAh power bank will recharge it 2-2.5 times;
A 20,000 mAh power bank will recharge it 5-6 times.
However, the exact number depends on a number of other parameters, including the charge current, the resistance of the connected cable, the weather outside, the time elapsed since charging and many others. Therefore, you should not hope that, for example, a 5000 mAh power bank will be able to recharge a smartphone with a 2500 mAh battery twice.
Charge current
The charge current value should be selected based on the same parameters as for conventional network adapters (power supplies). Considering that the stability of the current in power banks is not too high, it is worth choosing deliberately inflated parameters:
For mobile phones, old smartphones, players, smart watches, wireless headphones and other gadgets that do not consume high power during operation - 1 A;
For modern smartphones, tablets, low-power laptops - 2-2.5 A.
There are several models of power banks that support fast charging technologies. As a result, it is worth considering the compatibility of the charger and the smartphone with which it is planned to be used.
However, power banks that support fast charging technologies are not recommended for purchase. The batteries built into them usually “do not survive” the “squeezing” of 20 V/5 A from them. Therefore, the battery capacity drops, and after a few months you will have to change the power bank.
Housing material
The strength, durability and some operational characteristics of the power bank depend on the material of the case. Such devices can be made of plastic, metal, and also supplemented with rubberized inserts.
Plastic is a simple, inexpensive, but quite reliable material. Power banks with such a case are cheaper than metal ones, but at the same time they do not survive being dropped on the floor. However, plastic has an important advantage - external chargers made of this material are better able to withstand temperature changes during the cold season.
Metal is better able to withstand any falls and other mechanical impacts. However, power banks in such cases are a little more expensive. In addition, due to the fact that metal “accumulates” low temperatures, such devices self-discharge faster during the cold season.
Additional inserts - for example, rubber ones - either protect the power bank from shock impacts, or simply make it more beautiful.

Attention! This material is the subjective opinion of the authors of the project and is not a guide to purchase.If you are going to buy batteries, but you do not yet have a charger, or you want to buy a charger to replace the old one, then the question inevitably arises - which charger to buy, what to choose from the huge variety?
Why do you need a quality charger?
The service life of high-quality NiMH batteries with proper care is on average 3-5 years. The capacity of modern batteries is comparable to the capacity of expensive alkaline (Alkaline) disposable batteries, but unlike them, batteries can be used from 500 to 3000 times. The benefits of buying batteries are obvious!
In order for batteries to last a long time and work efficiently, it is necessary to choose the right charger. A common mistake many buyers make is buying expensive high-quality batteries and buying a cheap charger or using an old one they bought a long time ago. As a result, even the most expensive batteries will quickly fail.
There are at least 3 reasons why you shouldn't skimp on a charger:
1. Cheap chargers can charge batteries extremely slowly - up to several days;
2. Cheap chargers do not allow you to control the charging process and may not have automatic shutdown after the battery has finished charging. You have to calculate the charging time by eye, which is neither convenient nor accurate - the batteries can either be undercharged or overcharged;
3. Cheap chargers do not have protection against overheating and overcharging of batteries, which affects the life expectancy of the latter.
All these factors negatively affect the quality of the batteries and also significantly reduce their service life.
Problems can be prevented or solved with a quality charger. Manufacturers offer a wide variety of chargers aimed at a wide range of consumers: from advanced users who want to fully control the process and charging parameters of batteries, to ordinary people who do not want to know anything about the process of charging batteries.
What should you consider when choosing a charger?
When choosing a charger, pay attention to the following important points:
1. Availability of independent channels for charging each battery separately
Many cheap chargers only charge batteries in pairs. This creates a number of inconveniences in use. Firstly, you need to ensure that the pairs of batteries used in devices are not confused. Secondly, many devices use an odd number of batteries, which cannot be charged in such a charger. You have to look for some kind of additional battery to supplement the pair for charging, which is very inconvenient.
In addition, over time, the batteries in a pair begin to differ in capacity, which affects the duration and quality of operation of the pair. The difference in capacity can reach such an extent that, due to one undercharged battery, the pair practically stops working and it becomes impossible to use the batteries.
When choosing a charger, give preference to charging with independent channels.
2. Automatic detection of full battery charge
Cheap chargers either do not have automatic charge shutdown at all, or are turned off by a timer.
In the first case, the charger will charge the batteries until you unplug it yourself. In the second case, regardless of the battery capacity and the state of its charge, the charger will turn off according to a programmed timer, for example after 12 hours. Both options mean a high probability of undercharging or overcharging the batteries, which negatively affects their performance and life expectancy. Modern chargers use a special algorithm for determining the full charge of batteries, which is called –dV (“minus delta ve”). The essence of the method is that as the battery charges, the voltage on it increases, and at the moment of full charge it drops slightly. The charger detects the moment of a slight drop in voltage and stops charging the battery, as a result of which the battery is fully charged and does not overcharge.
In the case of charging Li-ION batteries, the “constant voltage / constant current” method is used, the essence of which is to limit the voltage on the battery. As the battery voltage approaches its maximum value, the charging current decreases. After the charging process is completed, the charging current stops completely. Failure to comply with these rules can lead to a rapid decrease in battery capacity, and failure to control the shutdown of the charging current at the right time can lead to a fire or even an explosion.
When choosing a charger, give preference to charging with the correct operating algorithm and accurate monitoring of the end of battery charging.
3. Availability of protection against overheating, overcharging, incorrect polarity installation
Cheap chargers often do not have any protection for the batteries. Meanwhile, overheating, overcharging and improper installation of batteries in the charger are the main reasons for the rapid failure of batteries.
High-quality chargers have special sensors that temporarily stop charging batteries if they overheat, prevent batteries from overcharging, and also have protection against incorrect battery polarity. If the batteries are installed incorrectly in the charger, it simply will not turn on.
When choosing a charger, give preference to charging with protection against overheating, overcharging and incorrect polarity.
At least the first three points are already enough to select a regular high-quality charger, which will be enough to safely and fully charge the batteries.
If you need a simple but high-quality charger, we recommend paying attention to the following models that meet the criteria listed above:
for battery type CROWN (6LR61/6F22)
4. Availability of the “discharge” function
The “discharge” function is a very useful function that allows you to extend the life of batteries and maintain high performance. The fact is that batteries are considered discharged when the voltage on them is 0.9 Volts, while many electronic devices turn off when the voltage on the battery drops only 1.1 Volts or even higher. When charging a battery that is not completely discharged, the “memory effect” appears over time, which consists of a loss of battery capacity and a decrease in its operating time.
To prevent the “memory effect”, it is recommended to completely discharge the battery before charging it. You can drain the battery using a flashlight or a child's motorized toy, but doing so runs the risk of over-discharging the battery. If the battery voltage drops below 0.9V, smart chargers may perceive it as faulty and not charge it.
Therefore, to discharge batteries, it is recommended to use chargers with the “Discharge” function. When using batteries in toys or flashlights, do not allow the batteries to become deeply discharged. If you see that the battery is already low (the flashlight is dim, the motor in the toy is spinning weakly, or the sound is distorted), replace the batteries.
5. Availability of additional functions and features
Currently, the most popular are smart chargers that allow you to independently set battery charge and discharge currents, accelerate battery capacity, measure and restore battery capacity.
Buying such a charger makes sense if you constantly use batteries and you need to be confident in the capacity and performance of the batteries. Also, such a charger is an excellent gift for anyone who uses batteries.
Smart chargers:
Separately, it is worth noting the smart chargers of the device, which are equipped with various additional accessories: AA and AAA batteries, travel bags, adapters. The quality of complete batteries and accessories is usually quite high, and the cost of batteries included is usually lower than the cost of similar batteries separately. Therefore, purchasing chargers with accessory kits can be very profitable.
Smart chargers with accessory kits:
Among the smart chargers, advanced chargers can be distinguished. These chargers are distinguished by the presence of additional functions and capabilities: screen backlight, measurement of internal battery resistance, a wide range of charge and discharge current settings, manual setting of the number of charge/discharge cycles for training/recovery.
Advanced chargers:
6. Ability to work with batteries of different formats and sizes
If you use batteries of different types (Ni-MH, Li-ion) or different sizes, in order not to buy a separate charger for each type of battery, you can purchase a universal charger that is suitable for charging several types of batteries. Universal chargers are no worse than separate chargers for each type of battery. In terms of functionality, they can also be simple, which simply charge batteries, or advanced, which can charge, discharge, test and train batteries, and measure their capacity. Universal chargers combine the ability to work with Ni-MH batteries of sizes AA, AAA, C and Li-Ion batteries of sizes 18650, 14500, 16340, 26650, etc.
Universal chargers:
7. Ability to work with a large number of batteries
There are situations when it is necessary to charge many batteries at once - 6 -16 or more. It is quite obvious that using the most common chargers for 4 batteries in this case is inconvenient; the charging process takes a lot of time and requires additional attention. Using multiple chargers can also be an inconvenient solution to the problem.
To charge a large number of batteries, there are multi-channel chargers that allow you to charge up to 6, 8, 10, 12, 16 batteries simultaneously.
Multi-channel chargers:
(The paragraph below is only for Ni-MH batteries, modern Li-ION batteries can be charged by fast devices with currents of up to 4 amperes.)
Currently, you can find many chargers on the market that are called super-fast, ultra-fast, etc. This means that they are able to charge batteries quickly. What does this mean in practice? This means that chargers use high currents to charge batteries - 1000 mah per channel and above. Without temperature control of the batteries and cooling system, high charging currents cause the batteries to overheat, which has an extremely negative impact on their life expectancy. A high-quality super-fast charger must have a good cooling system, thermal sensors for monitoring battery temperature, and an overheating protection system. Otherwise, the lifespan of the batteries may be reduced by several times that stated by the manufacturer.
Special fast chargers with temperature and battery charge level control:
As a summary, we can say that to charge high-quality batteries, it is advisable to purchase a high-quality charger that will ensure a long battery life and high performance. Choose the optimal charger, which in its functionality will allow you to work with your batteries at the level you need. Before purchasing, it is also advisable to consider whether additional functions may be useful to you in the future, even if you do not intend to use them now.

A constantly discharged smartphone or tablet has been the problem of the entire current decade, and this problem does not seem to leave us for the next couple of years. And why all? New models of smartphones and tablets come out model after model, but the batteries continue to remain at the same level, and in the end what do we get? Right! Charging a mobile device lasts for at least a day, or even half a day. Since stronger batteries have not yet been invented, we will take a different path - we will choose a better charger for a smartphone or tablet.
Agree, isn’t it good when a mobile device charges quickly and then holds a charge for a long time?! But here’s a standard charger, it will also be called simply a charger, it doesn’t particularly want to quickly charge a smartphone and as a result of this, the device can lie on the charger from 1 hour to 5 hours to be fully charged.

The conditions of modern life are such that a person can no longer do without mobile devices - be it a phone, a laptop, a GPS navigator, or a music player. All these devices need recharging, but it is not always possible to get to a regular outlet. It is in such cases that a portable charger will come to the rescue, which meets all the user’s requirements (convenience, compactness, light weight). Buying a portable charger in Minsk will not be difficult, since in all specialized stores you can choose the option you are interested in, you just need to decide on the basic characteristics of the purchase.
Thus, experts advise first of all to pay attention to the power consumption of the device (measured in volts) for which the purchase is made. Based on this parameter, “charging” should be sought with equal or greater power. If the device has less power, then instead of charging portable devices, it will...

Battery types
The battery charging process depends on its type. Let's list the main ones:
Nickel batteries are used less frequently than lithium batteries.
Lithium batteries differ in the type of electrolyte. In lithium-ion, the electrolyte is liquid. Their advantages include a long service life, but their disadvantages include low energy efficiency and significant weight. Lithium polymer batteries have a gel-like electrolyte. Therefore, the batteries have a small thickness and weight, as well as a large capacity.
When charging batteries, use only the original charger.
How to properly charge the battery?
For new phones, it is recommended to “cycle” the battery. This procedure is especially important for nickel batteries, which have a “memory effect”. If the charging mode is incorrect, such batteries lose capacity. Lithium batteries do not have this drawback, but nevertheless, some rules should be followed.
No need for lithium batteries...

A correctly selected charger is the key to successful operation of your battery. The durability of a battery is primarily determined by its charging mode. The main causes of damage may be overcharging and exceeding the permissible charge value. Nickel-cadmium batteries are the least demanding on the charging mode. NiMH and Li-ion require special charging modes. Although modern nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries can withstand overcharge, the resulting overheating reduces battery life. Lithium batteries, even if the maximum permissible charge is slightly exceeded, can be destroyed. Thus, for high-quality charging, it is necessary to control three factors: charging time, charge amount and battery temperature. Today there are quite a lot of chargers that provide good battery protection and control over the charging mode. The simplest...

Therefore, when purchasing a mobile phone, you should pay attention to the support of specific charger models, taking into account all the nuances relating to the scope of its operation. For example, if, for work reasons, you do not have the ability to recharge your device from the network, you need to buy a charger that will allow you to use it, regardless of your location. Among the main models of devices of this type, there are several main types, including network, automotive, universal, wireless, as well as solar-powered chargers.

It is almost impossible to imagine the disappearance of the mobile phone from the life of a modern person. It is an assistant, a toy, and a means of communication, but only if it has a working power source. A failed battery turns any device into a set of circuits covered in a plastic shell. And this happens at the most inopportune moment. There are many reasons for failure, but the most common is a violation of the rules for operating the device. The main distinguishing feature of a modern lithium battery is the presence of a circuit that controls the charging process.

Library: Popular about miscellaneousChargers for phones and more In general, the owner of a cell phone does not have to choose - we receive a charger complete with the device. And the maximum that can be done is to buy exactly the same another one (for example, to replace a broken one).
So there seems to be nothing to talk about. But usually a cell phone or smartphone is not the only digital “toy” in our arsenal of portable devices. MP3 players, digital cameras, voice recorders, MD players - there is plenty of equipment. And each device requires a battery, and each battery requires a charger... Let's talk about chargers. About the very ones that cause us grief with their abundance, diversity and incompatibility. Three small things, like a PDA, a phone and a player, and three different chargers for them. The machines themselves fit in pockets, but the chargers get tangled up in a bag or suitcase. So after that, talk about some kind of portability...
