How long the external battery is charging for the phone. How to choose and where to buy Portable Chargers (Power Bank) for phone and other electronic gadgets. Power Bank Charging Time

Let's figure it out together.

There are 3 main ways to charge Power Bank:

1 - from a computer, laptop - via a USB connector. There should be no difficulties in such a way of charging.

You simply connect a charger through a cable that comes with or any other with your suitable entrances / outputs.

Upon LED indication you will immediately see if the device is charged.

Standardly, the external battery has 4 battery charge indicators - 25%, 50%, 75%, 100%. Accordingly, when the last 4th indicator stops blinking, it denotes that the device has been charged completely.

But, keep in mind that the most simple budget can only be 1-2 indicators.

2 - second option, how to charge a portable charger - connect through network adapter In the outlet.

Standard adapters are not supplied with Power Bank, but there is no need.

Explain why - because External batteries are invented to charge smartphones, it will be logical to have an ordinary telephone charger, which is recommended to be used to charge your Power Bank from the network.

It is very important that you do not need to keep track of charging. Modern portable charging device Equipped with intelligent autotlope systems after complete charge and are thus protected from excess charging level.

So you can calmly put external battery To charging for the night. In addition, it is convenient, because The standard charging time of the external battery to - will be 4-6 hours.

3 - the last way can be charged an external battery - from direct sunlight, But this is just for - that is solar battery!

P.S. Car lubers can charge an external battery via a USB adapter from the cigarette lighter.

Today it is difficult to find a person who has no smartphone. Modern models are distinguished by versatility and multifunctionality. This advantage It becomes the reason for the lack of battery capacity. It is enough for only a few hours, which is quite problematic in the absence of charging. Power bank was created to eliminate this problem.

So called the energy storage agent. It can be used to restore the energy balance of discharge gadgets. Mobile source is characterized by a large capacity. The device has two standard USB connector, thanks to which any device can be connected to it. Instructions for applying the bank is simple. To charge the battery, you need to connect the gadget with a portable battery.

Power Bank is a class of universal charger. They are identical to batteries that insert the last generation into smartphones. For additional bonuses, a small weight is calculated, a function automatic shutdown When recharging small equipment. The voltage is usually 3.7 volts, and the container is from 2000 to 3000 mAh. Discharge and charge Power Bank is allowed 500-1000 times.

Indicators to pay attention to

Battery capacity is expressed in mAh. It is from him that the weight of Power Bank and its dimensions depend on it. The latter are characterized by specific energy-intensity and low self-discharge current. Choice specific model Carry out, focusing on the type of gadget used. Special attention should be paid to the charge of charging. It is in the range from 1 to 2 amps.

Learn Charging Time Your Battery

In the line of modern models, the Pole Xiaomi Mi Bank has devices, in the structure of which there are solar panels of charging. Thanks to them, the battery becomes more economical and convenient. Appearance And manufacturing material play a minor role.

The case of the model is metallic and plastic. When choosing the last variety, special caution should be observed. This is due to the risk of overgrown, one of whose consequences becomes the occurrence of damage. Premium devices include aluminum products. They are characterized by durability and unique design. Among the minuses, there are no differences in shape, tangible weight and high cost.

How much charging is enough

To find out the number of possible charging, you can use a special formula. When calculating, the capacity of Power Bank and the minimum self-discharge is taken into account. If the operating conditions are disrupted, the battery functionality is reduced over time. It is necessary to take into account the fact that the Power Bank cannot issue 100% of the energy available.

Xiaomi Power Bank.

How to charge Power Bank

Energy supply in the portable device is filled from a stationary computer, network or laptop. The process occurs faster if the Power Bank is charged from sources of electricity, the strength of which is equal to 2a. Saving time plays a big role. When choosing suitable way It is necessary to take into account certain nuances and features.

You can easily charge the Xiaomi Mi Power Bank through a socket by using a cable that is included in the standard set, a regular telephone charger (if block is separated), a USB cord from a computer or laptop. How much will the Power Bank have to charge depends on how the energy balance will be replenished. Experts recommend charging the device at night. So you can achieve maximum battery filling.

The direct "power" of the Xiaomi Mi battery will allow you to fill the charge much faster than when using a USB cord. Charging done by the solar battery should be carried out in full compliance with the rules that were listed in the instructions.

Devices equipped in a similar way are more than classic models. Some portable batteries can be charged using the smartphone itself. After the light bulbs on the external battery stop flashing, the device is not recommended to disconnect from the network for an hour. It is necessary to restore drip charging. If necessary, you can download a special application. Charge Power bank Xiaomi. 10,000 mAh will have to be within 3.5 hours. With a capacity of 20,000 mAh, a session duration increases by 1.5-2 hours.

Possible mistakes

If Power Bank Xiaomi Mi does not charge, you should pay attention to the "symptoms". For reasons that are able to cause malfunctions include:

poor quality device;
lack of timely charging;
the use of unsuitable devices;
mechanical damage.

If there are problems with switching phases and light bulbs, you need to contact the master. Independently to repair is allowed only if there are appropriate knowledge and experience.

So it happened that the standard autonomous work Smartphone or other some gadget today is in most cases - one day, and in general it is not bad and even logical - in the evening they put it on charge, and took off in the morning. But due to the numerous factors, our devices do not "reach" until late evening, and it is somewhat sad. Some of the most frequent reasons Quick discharge can be the intensity of calls or a weak network covering, connecting to the Internet, new applications also strongly affect the battery charge, only the game Pokemon GO is able to discharge the smartphone 3 times a day.

The solution to this problem can be a purchase Power Bank.. These devices have already been presented in our market, and they are engaged in their release. a large number of producers of varying degrees of fame.

External charging device is very useful gadgetWho more than once will help you to stay in touch, whether you are in the country, nature or a trip.

What is Power Bank

External Battery, Portable Charger, Power Bank, Universal Mobile Battery, Names Many, but the essence is one - this is a portable power source that is designed to charge mobile gadgets, and what it can be any device supporting charging via USB.

The package of Power Bank includes charging itself, as well as USB cable. Depending on the model and the manufacturer, the kit may include adapters for charging mobile gadgets with various connectors.

As a rule, Power Bank has a type of a bar, although models are offered to will be an interesting and atypical design.

The most important parameter Pouver Banca is its container. Here you should be repeated from what number of devices will be charged and from how long these devices need to be maintained in working condition.

What can be charged

smartphone;
the tablet;
electronic book;
portable speaker;
MP3 player;
camera;
fitness bracelet;
GPG navigator;
in general, a lot of things that may be charged via a USB cable;

How to charge Power Bank

Most of the external batteries are charged via USB input, but there are options that can be charged via Micro USB or using the Lightning port (connector).

To charge Power Bank Connect to it included in the package USB cable from the side micro USB. At the opposite end of the cable is standard USB inputWith which you can charge the Power Bank from the computer, a laptop or use a 220 volt adapter to charge directly from the outlet (from the network portable battery charging faster).

How much the device needs to be charged - you can tell you the information display of the gadget. In the absence of this alert system, charge more "people's" way - in the evening they put for charging, and in the morning an external battery is ready for use.

How to Charge from Power Bank

To charge your devices, connect the same USB cable to the battery, only on the contrary - connect the cable from the standard port side to the battery, and connect the micro USB, for example, to a smartphone or tablet.

Which to choose

The basic principle of the selection of the desired capacity is to optimize the weight and dimensions of the external battery. If you rarely remain in places without a socket, it will be enough to buy a turn of a small capacity, such a "baby" can be put in the wallet or purse. Well, and if you like to get into the mountains for 1-2 weeks, you will have to stock up a bigger battery.

Capacity

Portable charging capacity to determine easily, its manufacturers indicate almost everywhere - on the package, on the case, often fit into the name, but it is not so simple with it.

Power Bank for 4000 mpm watches will not be charged, for example smartphone iphone. 6 with batteries 1810 mA h twice from 0 to 100%, at best it will be one full charging cycle and still half. This is due to the fact that the real capacity of the battery for the issuance of the charge is less from the manufacturer's claimed due to the charge loss in the connectors, wires and the conversion of the charge in the phone.

How to find out the desired container

These calculations are approximate, and this formula will help you only assume what volume to count on.

To calculate the desired tank pottery of the bank, take for example an external battery from HiPER by a volume of 15,000 maps and the capacity of our smartphone, to example iPhone. 6 Plus - 2915 MAK. Next, following the example of the formula, we will find out how many times can be charged iPhone battery With a capacity of 15,000 Mah:

15000 / (2915 × 1.5) \u003d 3.4 - that is, the universal external battery HIPER MP15000 will give our phone 3 full chargeand one slightly less than half.

Housing

When it comes to the battery case, it is not so unequivocal here.

The housing can be plastic and metallic. Metal of course has high durability, scratch-resistant, and besides, it is a premium material, but in the case of accessory, this strength can harm the main device.

The thing is that the majority power enclosures BANK made of metal possess sharp edges, and at the expense short wire The external charger and the gadget will have to be transferred together. When contacting devices, the bank can scratch your smartphone, so or wear your gadgets as carefully considering this feature or trust soft plastic.

USB cable

Almost all external batteries are equipped with a USB cable, but if you are owner apple products Check that the appropriate adapter enters the package.

How many amps

An important indicator on which the charge rate depends is the current power. On the this moment The most common two values \u200b\u200bare 1 and 2 ampers. 2 amps are always better because the gadget will be charged faster.

There are no rare models at once with two or three USB ports. As a rule, one of them is 2 amp, but here you need to take into account the fact that a portable loading device can be given only when one device is connected. If the charging is performed simultaneously, for example, on two channels, the current strength on both will be 1 ampere.

It will not be worthwhile to pay attention to the current current of the incoming port of the pan. The ideal option will be when the current is equal to two amperes + 2-amp network chargingBut this is relevant only for external batteries with a large capacity, since otherwise they can charge for a very long time.

Notification system

The minimum functionality that any external battery must have a charge indicator. It will be 4 LEDs or a full-fledged screen - this choice is already individual for everyone.

In principle, and on diodes it is easy to understand, in what condition is the battery. You will be surprised, but some models do not even have such a simple alert system.

Price

This section refers to one of the advantages of a portable charging device, as it has a relatively available cost, which is often comparable to replacing the built-in battery in service center Or buying additional charges to work or car.

So, finally, you have mobile Charger (Power Bank).

Congratulations! Buy Power Bank in Ukraine - Very correct decision!

(If you just think about such a purchase - in which you will order)

Of course, you would like charging to serve as long as possible and pleased your gadgets perpetual "online". To do this, you need to know some features of Li-Ion batteries and comply with several simple rules Use:

1. After buying an external battery, immediately charge it completely.

The perfect charging process (both workers and the batteries of your phone / tablet) includes both the so-called "drip" charging - charging the gadget is some time after the indicators show that the device is charged 100%, while the charge continues very Weak current.

For smartphones and tablets created special applicationsrecognizing the "drip" charging:

http://bit.ly/battery-doc - for Android

http://bit.ly/Battery-Doc2 - for Apple (the application is no longer available in the AppStore)

Previously, to find out when the "drip" charging is over, you needed a special measuring equipment (ammeter, voltmeter - tester). As all this technique works, it knows a rather narrow circle of radio amateurs, and not everyone will want to delve into all these details (even for the sake of increased battery life).

That is why they became such a joyful and saving novelty for everyone.

With this small device, you can see not only the voltage and current strength, but also the amount of AH (Amp / hour - the unit of measurement of the container for all batteries), which passed through USB tester. Therefore, you will always know in what condition is the battery of your phone, tablet or, since we are talking about Power Bank, capacity Power Bank..

()

Usually charging Power Bank. Current flow 1-1,5A. The closer to the end of charging, the less the amount of ampere. "Drip" charging is 0.1-0,05a. In order for your battery to have maximum capacity As long as possible, wait for the end of the "drip" charging. Once yours USB tester Shows 0.00a - charging is fully completed and the device can be disconnected from the network.

2. In order for your Power Bank to score its maximum capacity - you need to make 2-3 full charge / discharge cycles.

Also, if in the future Power Bank began to discharge faster than usual, it is worth repeating this cycle of 2-3 repetitions and thereby rewrite the battery statistics.

3. Always charge Li-Ion batteries up to 100%!

Try never to stop charging ahead of time - only after the battery charges 100%. Yes, many will say that "modern Li-Ion batteries do not have a" memory effect ". Yes, manufacturers also claim it. But, based on ours Practices and experience, this is not quite like this: in the Li-Ion batteries this effect is much smaller, but still being present (it concerns the phones, and any other gadgets).

4. Do not discharge PowerBank completely (up to 0%)

Modern Li-Ion batteries that are completed mobile batteries Do not require this. Moreover, their constant discharge up to 0% reduces the service life. Charge Power Bank when there are 10-20% charge in it.

In external chargers With the percentage indication of the level of category / charge, it is very simple, in devices with LED indication - you have to do it "on the eye".

(devices with% indication you can find )

5. This item is contrary to the previous one, but nevertheless it is also very important: from time to time, completely discharge the battery (once in 1-3 months).

This allows you to reset the charge borders (upper and lower - calibrate Power Bank).

6. If you do not plan to use an external battery for a long time - discharge it about half.

Store fully charged (as well as a fully discharged) battery is very harmful to him and significantly reduces its service life.

7. Use only original network chargersor those that have the required characteristics (if PowerBank. Recommended to charge the current in 2a, then use such a charger that gives 2a).

About network adapters worth saying separately:with them a real trouble. Find this that gives the claimed current - the task from the section is very complex. Even buying an expensive adapter in the corporate store, very often you get at the outlet not 1a, but 0,5a. And this is still half trouble (just your phone / tablet at the same time will be charged 2-4 times longer). Much worse, if in fact it gives a much greater current strength and does not smooth out significant voltage jumps - it can already strongly reduce the battery life of your gadget, and sometimes to its failure.

The problem is that if you do not have a USB tester, you can't find out, you have a normal charging or not. The phone is charged - everything seems to be fine. It is precisely for this that disposable manufacturers and sellers (the same can be said about cables - even if the charging gives 1a, poor quality cable can lose up to 80% current, and you will not recognize anything without a tester).

That is why we almost always recommend our customers to order immediately and the USB tester. This purchase will pay for the cost of it more than once! Here You will find various : more expensive and cheaper, more and less informative. But whatever you choose - it will be one of the most useful and smart shopping!

By the way about network chargers:

for a long time, we did not sell them at all because of this: they could not find a reliable supplier who had good and (which is very important) constant quality. However, buyers were constantly asked, and we did not stop looking. After many control purchases managed to find. Now you will find we have many high-quality original Charger . Among them -

8. Do not allow PowerBank overheating - both during charging and external factors (heating battery, straight sun rays, etc.)

If you do not neglect these tips, your PowerBank (as well as any other device) will serve you for a long time.

Hello, dear friends. Today, people use and take a bunch of portable equipment on the road - these are phones, laptops, tablets, cameras, players, navigators, etc. But the charge of these devices are held not so long as I would like. So that you do not happen to such an annoying event, as the discharged electronics, I advise you to purchase portable chargers.

Previously, I used my phone only for direct purpose - for calls. If I had a long road without the possibility of recharging, I just turned the phone as unnecessary and did not even think about the need for external batteries.

But since I broke up with my camera, I rent a phone, and it turns on quite a long time and during this time you can skip an interesting frame. Of course, I do not want to stay without charge at the most inopportune moment, you can use charging covers, but this is not enough, and something except the phone, they do not recharge them.

Especially acute the lack of battery, we felt. There we were a whole week without the benefits of civilization. And if you have a technique with you, for example, an action-camera, then you already need to acquire Power Bank, which, in fact, we did and rejoice can not - an indispensable thing for travelers.

So today I decided to consider the topic portable charging, We will find out how to choose them and how much it costs.

What is the external battery

External battery or Power Bank is a portable power supply with USB ports, which is charging itself, and then gives the charge of your technique.

How to choose it correctly

Let's deal with what better to buy.

The characteristics for which you want to pay attention to when selecting the battery:

Device type

there is power Bank.which is charging in three ways:

From a computer via a USB connector.
From the outlet through the network adapter (so much faster).
From the cigarette lighter in the car through the adapter.

And there is so-called sOLAR POWER BANK. (on the solar battery), which among other things, should still be charged from direct sunlight.

Such banks are, unfortunately, just marketing stroke. Manufacturers make everything that we want to buy them: they are made bright, beautiful, moisture-proof, even shockproof, with lanterns and with special loops for attachment on clothing or equipment with a carbine.

... Make everything except the powerful solar panel, which is unless that for beauty (well, of the excess weight of course), in fact, the power of such a panel is enough only to ensure the burning of the LED in the charge indicator.

Battery capacity

It is measured in amps-hours (ACH) and Miliamper-hours (Mach or Mah). The greater the capacity large quantity Since the portable device will charge your technique.

This does not mean that your bank is a capacity of 2,000 mAh charges a battery with a capacity of 1,000 mAh twice. Chargers lose energy during charging, it affects a bunch of factors up to ambient temperature.

Miracles do not have the greater the capacity, the greater the dimensions and weight of the device. Here everyone chooses the optimal ratio for it, based on its own needs. If you just have a smartphone, it does not reach the end of the day, in this case, there are enough 5,000 mAh, and if you go to long trips, then you need to take a maximum, maybe 20,000 mAh are not enough.

If you are close to both these situations, you can buy two turns of the bank. Less capacity for everyday use and greater - for travel.

Capacity also determines the price of these devices. It should be borne in mind that banks are not eternal, over time they degrade, the actual capacity decreases and after a few years they have to be replaced. Therefore, I believe that even for the very tank bank, it is not worth paying more than 3 thousand rubles.

output power

It is necessary that the power of the charger is greater than or equal to the battery power of your electronic devicesOtherwise, the bank will discharge the device instead of charging.

So before purchasing the Power Bank, we look at the power in the instructions for your devices and we carry them out with the power of the bank. Power, if forgot from the school program, is expressed in watts (W or W).

Output current (in amperes, a)

It is recommended to comply with the manufacturer's recommendations of the connected devices. You can see the strength of the current on the native charger, which went in the kit. For example, on my charger from the smartphone, a current of 1 A is indicated, and from the tablet - already 2 A.

This does not mean that you do not charge the tablet from the USB c current to 1 A, it will simply be slower than if it was 2 A. The more value, the faster it will charge the connected device.

You will also charge the smartphone from 2 A, exceeding the manufacturer's recommendations, but at the same time remember that its battery is spoiled.

The ideal option is a battery with two USB, on one of which the current is 1 A, and on the other - 2 A.

Number of USB ports

The number of connections and the number of simultaneously charging devices depends on the number of connections. Usually their one or two. It is better to take with two, one is not enough.

Corps material

There are metal and plastic cases. Metallic, of course, looks stylish, but we do not care for beauty. Therefore, I advise you to take plastic, it is easier, which is very important for a tourist backpack.

Device charge indicators

Now almost all models are equipped with LEDs, they approximately show the charge remaining in the battery. There are digital indicators in the form of a small display, but they add cost, but the precious charge is eaten.

Mark.

Of course, it is better to take the original products from the famous brand and be calm in your safety. After all, with poor-quality electronics, the jokes are bad, it can explode, and output charged devices, and, at a minimum, spoil your phone or tablet battery.

But more expensive - does not mean better. Most recently, we discovered the Chinese company Xiaomi, which, as it turned out, produces reliable electronics at a good price.

It was this company that we bought our bank. The main advantage of its advantage, in addition to the capacity, is that it is universal. No need, changing the device, worry about compatibility with the bank.

Our Xiaomi Power Bank 20,000 Mah, as in the photo below, is compatible with the main rules of smartphones and xiaomi tablets, iPhone, Samsung, HTC, Google, BlackBerry, charges digital cameras, PSP and even MacBook.

We really like it and completely suits everything, so I recommend to buy.

Where is safe and profitable to buy a turn bank

Where better to buy? In the electronics store in their city or order via the Internet?

Of course, if you go and buy a product in a large retail store store, you will be confident in its originality, but you overpay for it 2 times.

How to save? Right. Buy via the Internet!

Many people are still afraid of making purchases on the Internet, in the case of electronics, most often they are stopped by fear of what "happen that, who will replace it for warranty?" I don't even know what Sharashka should I buy in order to arise with the warranty and return of the goods.

Although I admit that on sites like
