Power supply for fast phone charging. How to choose a portable charger? How to charge your phone: the main rules

So, you choose a charger for your phone. The two most important factors that will help make right choice, this is the type of memory and the strength of its output current. Let's consider each factor in more detail.

Charger type

Which charger do you want to buy: original, suitable analog or universal charger? Of course, many choose the original. In this case, you do not have to worry about the compatibility of the device with the phone, charging features, fire risks (cheap chargers sold in bunches in the markets can lead to fatal overheating of the battery). But it happens that the original memory is too expensive or difficult to find in stores. A high-quality analogue of the original network charger for the iPhone will help out.

The quality of an analogue cannot be judged by the country of origin. The inscription "Made in China" can also be seen on the original, because well-known brands make their phones, as well as components and accessories, in China. A good analogue should contain a list of compatible phone models and technical specifications that repeat the characteristics of the original.

Most modern tablets and smartphones have adopted single standard power connector - microUSB. Therefore, it is advantageous to choose universal chargers with microUSB that can be connected to all your gadgets. One of them is the Partner wall charger. Please note that the output current of such a station wagon should not be lower than 2.1 A.

Output current

Why not lower than 2.1A? What is this parameter and what does it affect? In short and generally speaking, while charging the gadget. On the device, the output current can be marked as "output" or "output", the numbers indicated next to it mean how much current the memory is capable of transmitting. Charging a smartphone usually requires a current of at least 0.7 A. For a capacious tablet battery, about 2 A.

If you connect a phone charger to a tablet, it will take a very, very long time to charge. Smartphone chargers are rated at 1A. If you connect a 2.1A charger to your smartphone? The phone from such a charge can burn out? No, smartphones are provided with a power controller that does not take more than the smartphone needs. But the gadget will charge faster.

In addition to mains chargers, you can also charge smartphones via the laptop's USB port. However, it is likely that the gadget will stand on charge for a long time. The USB format was created at a time when phones were not supposed to be connected to a computer, so USB ports are not designed to power a third-party device. Through them, charging with a current of only 500 mA (0.5A) will go.

To speed up your phone's charging time, put it in "flight mode"/"airplane mode"/offline mode. In such conditions, all unnecessary applications and modules are disabled. The smartphone will charge at least 15% faster.

To calculate the parameters of a charger for a specific battery, you must first take into account the type and parameters of the battery that you are going to charge with this device. The most important characteristics of a rechargeable battery are: capacity, full charge voltage, maximum allowable charge current, as well as the range of allowable operating temperatures.

Depending on what kind of battery it is, what type of materials it uses, the parameters of the charger must be selected individually. Here we will look at lead-acid and lithium-ion batteries, or rather, the features of their charging.

The truth is that if the battery is always charged correctly, with optimal voltage and current values, then it will retain its capacity over many charge-discharge cycles. Of course, provided that it is also discharged in compliance with the restrictions, without overloads, without overheating. So, how to calculate the parameters of the battery charger?

Li-ion battery

The main charged particle responsible for current generation is the positively charged lithium ion. It is capable of incorporating into the crystal lattice of the material at the anode, for example in carbon in the form of graphite, and also to form metal salts or oxides (for example with manganese, cobalt or iron and phosphorus).

By virtue of this chemical composition, the maximum final charge voltage between the electrodes of a lithium-ion battery should not exceed 4.2 volts, or better, 4.1 volts, this will extend its service life and slow down irreversible changes.

It is necessary to charge a lithium-ion battery with a voltage of 5 volts so as not to wait indefinitely. In this case, the optimal charge current should be from 50 to 100% of the capacity value, that is, a battery with a capacity of 2400 mAh will optimally charge with a current of 2.4A to 1.2A.

To prevent overcharging, high-quality chargers charge such batteries in 2 stages: at the first stage, 5 volts are applied to the electrodes and the charge goes on for some time with the maximum allowed current until the threshold voltage is reached in the region of 4.1 volts, and then the second stage begins - with a lower current, when the voltage is brought to the final 4.1-4.2 volts.

Therefore, the capacity of the charger for a lithium-ion battery (for 1 cell) is calculated as follows: maximum voltage multiply by the maximum current, let's say 5V * 2.4A \u003d 1.2W - for our example.

Lead acid battery

Lead-acid battery works thanks to chemical reactions lead and lead dioxide in an aqueous solution of sulfuric acid. Any classic car battery is designed this way. During charging, lead sulfate decomposes into ions (negatively charged SO4 and positively charged H), lead dioxide is formed at the cathode, and pure lead is formed at the anode. During discharge, metallic lead is oxidized to lead sulfate, lead dioxide is reduced at the cathode, and lead is oxidized at the anode.

If the battery is recharged (kept on charge for an excessively long time), then lead sulfate will end, only water will remain, and its electrolysis will begin: oxygen will be released at the anode, and hydrogen will be released at the cathode (negative electrode) - in the liquid electrolyte it will be seen how they will go bubbles.

Due to this particular chemical composition, the voltage of the maximum charge of one cell of a lead-acid battery is 2.17 volts. In a 12 volt battery there are 6 such series-connected sections, and in a 6-volt battery there are 3 series-connected sections. Therefore, the maximum charge voltage of a 12 volt battery is 13.02 volts. For 6 volt - 6.51 volts.

Thus, the charger during the charging process must supply a constant voltage to the electrodes based on at least 2.45 volts per cell (so that charging does not go on indefinitely) - for 12 volts this is 14.7 volts, and for 6 volts it turns out 7, 35 volts. The initial charge current is optimally taken as 30% of the capacity.

As a result, the maximum operating power of the charger should be calculated as the maximum voltage multiplied by the maximum current, let's say 14.7V * 30A = 441W - for a lead-acid battery with a nominal voltage of 12 volts, with a capacity of 100Ah.

With this article, our site continues the whole cycle useful materials, the purpose of which will be to facilitate the choice of any product from the thousands of options offered on the market. Agree choice. specific model some device always takes a lot of time, which can be spent usefully. In today's article we will talk about the choice portable charger .

A modern person carries with him a huge number of mobile devices - a smartphone, tablet, laptop, camera ... All this constantly needs to be charged, and there is not always access to a power outlet - especially if you went camping. It is for such cases that special portable chargers were invented - in fact, huge batteries with a variety of charging outlets. different devices. IN last years their popularity has multiplied.

In the next section, we will cover the main technical specifications portable chargers, and then we will present to your attention the 10 best models that you can find and purchase in our catalog.

Key features to look out for

Capacity, mAh

The main characteristic of any battery is its capacity. The larger it is, the more energy the charger can transfer to a smartphone, tablet or other device.

For one or two full charges of a smartphone, a capacity of about 4000-5000 mAh is enough. To charge the tablet, you need a larger battery - for example, with a capacity of 10000-15000 mAh. The laptop will require even more - to charge it, it is better to buy a charger with a capacity of up to 20,000 mAh.

Maximum output current, A

The maximum output current of the battery affects the charging speed various devices. At the same time, it is worth remembering that the device receiving energy must maintain the set current value, otherwise its battery will simply overheat and may even explode. Fortunately, modern electronics are usually smart enough to automatically lower the current when needed.

A current of 1 A will be enough to charge a smartphone (flagships support faster charging), 1.5-2 A to charge a tablet, 2 A or more to charge a laptop. It all depends on the specific model - before buying a battery, be sure to find out what current strength your devices support.

Ability to charge two devices at the same time

These words speak for themselves. A device that supports simultaneous charging of two devices will be useful for those who often use a smartphone and tablet or a smartphone and a laptop - you do not have to alternate charging these devices.

Ability to charge laptops

Only powerful and expensive chargers have such an opportunity. Before buying, make sure you have a special adapter for your laptop!

card reader

The built-in card reader is useful if you often charge the battery itself from a PC and use memory cards - an extra card reader will not take up another USB port.

Flashlight

The presence of a flashlight in a mobile battery allows you to use it without fear of draining the battery of your smartphone. In addition, flashlights in portable chargers are usually brighter than LED flashes in phones.

Solar battery

The presence of a solar battery on the body of the device allows you to charge it from sunlight- useful if you are going to spend a lot of time outdoors in good weather or just like to save money. The speed of such charging directly depends on the cloudiness and even in ideal conditions not at all high.

Number of USB connectors

Most often, portable batteries are equipped with one or two USB ports, so they can charge one or two devices. Very rarely there are models with three ports or more - in most cases they are not needed.

Availability of a universal output connector and adapters

To charge the whole variety of different mobile devices, portable batteries are equipped with a universal connector, and many adapters are placed in the box. Before buying, you should make sure that the kit contains the adapters you need - for example, for a car or Apple laptops.

Type of connection to the power supply

You can always charge the battery itself from a stationary PC via USB, but often a wall charger is also included. Various adapters for mini USB or micro USB ports may also be present.

Waterproof case

The presence of a moisture-proof housing is useful if you plan to use the battery on a hike or in nature in general - once in the rain, it will not become a useless piece of plastic.

How to choose it and what you need to know?

When choosing a charger, first of all, you need to know the type of battery installed in the car, because some of them require personal attention and approach.

For example, this applies to lead batteries - they require the use of special chargers.

For most batteries - almost any universal device is suitable.

Although modern devices allow you to simultaneously charge almost any battery using several values ​​​​of output power and charging current.

Features of the choice of charging for the battery

Having decided on the type of battery that needs to be charged, the choice best model continue with other features.

It is advisable to give preference to compact portable models, which are more convenient and easier to handle.

And, when choosing between equipment powered by a cigarette lighter and a single-phase network, you should pay attention to the second option - chargers that require standard 220V.

And, as a rule, they provide at first half of the battery capacity, gradually reducing the power until the final charge.

To protect the batteries from overcharging, each device is equipped with a special protection that automatically turns it off when the battery is 100% charged.

Among other parameters that need to be considered when choosing a charger, it should be noted:

• the capacity of the batteries to be charged. For passenger cars, it is, on average, from 40 to 62 Ah, for motorcycles - up to 20 Ah, for minibuses - up to 120–160 Ah;
• charging current. 6 A suitable for batteries up to 60-70 Ah. 12 and 18 A - the best option for minibuses and SUVs;
• price category. The cost of most models is at the level of 2000-3 thousand rubles. More functional equipment will cost 5 thousand or more.

The brand of the charger also matters. German-made chargers are considered the most reliable and efficient devices. While Korean models are different affordable price with fairly good performance.

Popular charger models

Almost any modern charger copes with battery recovery. cars and small commercial vehicles within 6-10 hours.

The same devices allow you to restore the performance of a completely discharged battery. At the same time, the recovery time of the battery capacity with a zero charge is calculated taking into account 10–15% of the reserve.

For example, a device with a current of 6 A will charge a 60 Ah battery not in 10, but in 11-12 hours.

If the battery is charged by a third (it is from this moment it is recommended to start charging) - respectively, in 7-8 hours.

If you want to reduce this time, you should buy a more powerful device. At the same time, choosing a device with automatic floating adjustment of parameters will increase the service life of the batteries. Setting the charging current to a lower value will increase the charging time, but also improve recovery. If the charger does not have an automatic adjustment function, the user will have to monitor the battery on their own.

Low smartphone battery life actual problem modern man for whom it is important to always stay in touch. Due to this lack of gadgets, users are forced to regularly incur additional costs - for the purchase of external batteries, for paid charging services in stores, even for the purchase of "second" phones that can "insure" the main device in case it "sits down".

However, the fact that the gadget is quickly discharged, as a rule, the user himself is much more to blame than the manufacturer. By following some rules for charging your smartphone, you can significantly increase the duration of its battery life.

Why is my phone charging fast?

The user should not be surprised by the fact that a simple “dialer” is able to work without an outlet for 1-2 weeks, while the smartphone sits down a day after the last recharge. The functionality of push-button phones is usually so primitive that putting the battery just nothing. At the same time, smartphones have a whole arsenal of additional options, thanks to which they can successfully replace navigators, cameras, game consoles and other highly specialized devices. All these options are rapidly "eating up" amps.

Here are the main enemies of smartphone batteries:

• WiFi. If the Wi-Fi module is enabled, the battery consumption is much faster. If the distribution of wireless Internet is also activated on the smartphone, you can see how the countdown of the percentage of battery charge goes right before your eyes. Important point is that the included Wi-Fi drains the battery to a greater extent during periods of searching for a network than during a permanent connection. That is why, leaving the reception area, you should not only switch to LTE, but also turn off Wi-Fi.
• Geolocation. Thanks to the enabled geolocation, the user of a mobile device is able to track his location on the map and find out how far it is to the destination. Many people do not feel such a need, and therefore geolocation works in vain on their smartphones, devouring precious milliamps.
• Long conversations. In the specifications, the approximate battery life of gadgets is always indicated in 2 versions: In standby And in talk mode. The talk time is much shorter. The user should, if possible, replace live communication with correspondence in social networks and instant messengers if he wants his device to last longer without recharging.

Contrary to popular belief, apps running in the background on your smartphone have almost no effect on battery consumption. Starting a program from scratch is a much more energy-intensive procedure, so if you use any application constantly, it's pointless to close it every time.

The reason for the rapid battery consumption is not always located on programmatic level. Perhaps the whole point is a technical malfunction, poor quality of the battery, or wear and tear. Each battery has its own service life, which is measured in the number of charge cycles. Upon reaching the threshold, the smartphone starts to sit down faster with each new charge.

The iPhone has an estimated battery life of 500 cycles, which is one and a half to two years of use. From the 501st cycle, the battery of the "apple" gadget begins to lose efficiency. After reaching the 1000th cycle, the battery capacity is usually only 50% of the original. You can find out the number of charge cycles on the iPhone using the program battery life.

Slow charging: what is the reason?

The reason that the smartphone is charging slowly, is hardly a malfunction of the gadget and its components. Most likely, the problem lies in the elements of the charger or in the power source.

If the smartphone is charged not from the outlet, but from the port of a laptop or PC, one should not expect that the battery will be filled “to the brim” in the usual time. USB port format 2.0 provides power in just 2.5W, whereas for recharging a battery with a capacity of 3000 mAp approximately 5 W. Better with the task of recharging gadgets, ports of the format 3.0 giving 4.5W.

However, if the laptop is equipped, then you can forget about connecting the smartphone to the outlet forever. new type USB can charge devices with up to 100 W, which means that it will not be difficult to quickly fill the battery of a mobile phone and even a tablet through this outlet.

Poor USB cable quality and insufficient adapter specifications can also be the cause of slow charging. When choosing an adapter, pay attention to current power- an indicator expressed in amperes (A). Previously, this moment had to be taken into account - if the current power was low, the device was charging slowly or “did not get enough” capacity. At the same time, it was impossible to “go too far”; too much current could harm the battery. In 2019, this problem does not exist.

There is no need to worry about the fact that too powerful current will “burn” the smartphone - all gadgets have special charging controllers that do not allow more current to pass than the device can withstand. In addition, high-quality SZU has similar controllers.

How to charge your phone: the main rules

Users of mobile technology still remember the rule from the 2000s: discharge the phone to 0%, then charge it fully. This rule only applies to nickel batteries, which now you will not find "by day with fire." Most smartphones come with lithium-ion batteries that cannot be discharged to zero - this causes irreparable harm to them!

In recent years, manufacturers of mobile equipment began to receive information that in order to "maintain" the life of the battery, it should be kept at a level of 20 to 80%. Of course, you can go beyond these limits, but ideally you should follow the recommendations. In some modern gadgets, the function of automatically cutting off the power supply when the capacity reaches 80% is already implemented at the hardware level, or there is a corresponding option in the power settings settings. Representatives of the company Asus spoke about this mode. If there is no special function, then nothing prevents you from installing the appropriate software from PlayMarket or AppStore, which will perform a similar task.

• Do not leave a fully charged smartphone connected to a power outlet Especially all night long. This leads to overheating of the battery and, as a result, to a reduction in its life. To avoid disastrous consequences, the user should pay attention to impulse memory - how they differ from ordinary ones, we will tell later.
• Keep track of temperature. During recharging, the smartphone already heats up - if it is also left in the sun, then it can easily fail. Of course, the device should not be covered or hidden somewhere. All this is additional heating and, as a result, a possible breakdown. Don't forget that low temperatures no less detrimental to the battery. The reference ambient temperature for charging is 20 degrees Celsius.
• Refuel your smartphone regularly- at least a little bit. Short-term charging is not a detrimental measure for modern lithium-ion batteries This has been proven by an organization called Battery Research and Manufacturing University (Cadex). In order to be able to feed the gadget in any conditions, it is worth purchasing the so-called power bank- external battery . Our site has already talked about how to choose an external battery for a smartphone.
• Once every three months (but not more often) completely discharge the smartphone and charge up to 100%. This measure will allow you to calibrate the electronics that are responsible for correctly displaying the percentage of charge. A user who neglects such a measure should not be surprised that his gadget "suddenly" turns off at 5-10%.
• To not allowdeep discharge . This concept means a long stay of the smartphone in a discharged state. The gadget is discharged and does not turn on- one of the most common complaints from users claiming warranty service.

An important point - if the phone is planned to be "mothballed", that is, they will not be used in the near future, the battery should be charged up to 50%. In this state, the device must be turned off. It is impossible to completely discharge or charge the smartphone before sending it to temporary rest.

The recommendation to use only original accessories for recharging is highly questionable. Of course, fuel the gadget better themes The memory that was included in the kit. However, if it fails, the user will face a serious dilemma due to the understandable desire to save money - after all, the original accessory is two to three times more expensive than the universal one.

In fact there is no big difference between universal and original memory. If a universal charger for a smartphone is made by a well-known company, and not by a Chinese "know-name", it definitely will not ruin the gadget.

How to properly charge a new battery?

Following the advice to discharge and charge a new smartphone three times is a sure way to “ditch” the battery in the first days of use. So it was necessary to do this again with nickel batteries - as for lithium batteries, each complete discharge significantly reduces their service life.

Modern gadgets do not have special requirements for the first charge. Users do not need to believe in the “noodles” that consultants and “pseudo-experts” of thematic sites “hang on their ears”.

It is best for the smartphone owner to take the instructions, find what it says about the charging time, and leave the gadget connected to the outlet for the time indicated in the manual. After this time, you should turn off the device with 100% power supply and then follow the rules listed above.

How to choose a charger for a smartphone?

Many of the options to look out for when choosing a phone charger have already been mentioned in this article. In fact, for modern gadgets, SZU is selected according to the principle - the higher the current strength, power and voltage, the better. The fact is that a few years ago, powerful charging could very well burn the battery. In 2019, power supplies have controllers and modes that determine what exactly is connected to them and, based on this, they supply current with safe parameters.

Other options to consider when buying are:

• Type. All memory devices are conditionally classified into 2 types: transformer And impulse. Pulse ones differ in that they are equipped with timers that can automatically stop charging. The fast charging mode of a pulsed charger lasts about 4 hours - this time is usually enough for the battery to gain the bulk of its capacity. Then the energy begins to be supplied in small portions - "impulses" - so that the smartphone does not lose charge.

• Construction and design. One-piece chargers that do not allow the user to disconnect the wire from the power supply are a thing of the past. Purchasing this charger disadvantageous, because the owner of the gadget has to buy a USB cable “in addition” to it - if he intends to download data from a PC to the smartphone.
