External battery for phone: selection criteria and how to use

Modern mobile devices and all kinds of gadgets are equipped with many fashionable and useful functions and applications. Yes, and the most complex mobile games amaze with graphics and capabilities. It is thanks to such applications that any smartphone "sits down" during almost a day. Therefore, you need to learn how to choose a more powerful external battery for your phone. Or choose an additional power source.

The main reasons why you just need to choose a new charge

So, the phone became often and quickly discharged. To begin with, it is necessary to determine the main reason, and only then to find the most optimal ways to solve the problem. So what are the causes of early discharge?

If the smartphone or tablet is new, the instructions say a certain duration of work, but in fact, the device works several times less, then the reason can be covered in the settings. As a rule, on the phone itself you can adjust the brightness and power consumption or disable several applications that pull the charge.

Another thing is, if the smartphone is configured, for a long time it worked quite normal, but eventually it was discharged much faster. Here, most likely, the internal charger or the external battery of the phone is to blame. The only solution is to replace the element. To do this, you can use both a proprietary battery and a universal analog.

Types of external batteries

Despite the prevalence of cell phones and smartphones, in the world so far there are only three main types of batteries:

• Lithium-ion . This is probably the most common external battery for charging the phone. It has a more optimal ratio of durability, safety and energy intensity than other analogues. Also, such elements are endowed with a special "memory effect" and are slowly discharged. But they quickly grow old, and even in the case of constant exploitation.
• Nickel-cadmium . Recognized as the most harmful and were put on the shelf. They were used only in the very first phones due to low cost. In addition, the higher their energy intensity, the higher the physical size.
• Lithium polymer . These are more cheap and improved external batteries for cell phones. Therefore, these elements have adopted all the positive aspects of the original sample, and have also become more environmentally friendly.

Features of operation and operation

A mobile phone is quite a complex and delicate mechanism. And each of its elements has its own characteristics and requires certain operating conditions, including the battery itself. Therefore, there are several rules, which, if carried out, can significantly extend the duration of the telephone battery:

• When used, it is necessary to strictly observe the operating rules specified by the manufacturer, i.e. do not overheat, do not wet and do not overcool.
• Try to avoid physical damage to the element.
• External batteries for mobile phones can not stand frequent strokes and falls.
• Do not open the batteries for the sake of interest.
• Replace and recharge the battery only when the device is turned off.
• It is not recommended to constantly charge the gadget for a long time (more than a day).
• The more and more often the battery is used, the better.

Myths about mobile batteries

For all of its existence, mobile phones have been overgrown with various fictions and legends that frighten naive users. Several of them concern the most important part of them.

1. Any external battery for charging phones can not be disconnected from the power supply, if it is not fully recharged. Lithium-ion and polymer charge, on the contrary, it is better not to discharge completely, because they quickly deteriorate.
2. Sometimes it is required to perform a full cycle of charging and discharging the batteries. This is relevant only for lithium devices.
3. Each new battery needs to be charged for the first time for a long time - more than 16 hours. As a rule, for any battery, the heat and long mains power are destructive.

Parameters that should be taken into consideration when selecting chargers

Choosing an additional external battery for the phone, you should consider a number of factors (in addition to the manufacturer and the quality of materials). As a rule, experts identify several basic parameters by which these elements differ. Therefore, knowing these features, you can choose the appropriate option.

• The capacity of the battery presented . It directly depends on the operating time without additional recharging. As a rule, 4000-6000 mA / h is enough.
• Current strength . If the battery is used to power not only the smartphone, then you need to choose a device with a power of 1-3 A. For a normal phone, enough apparatus that produces 1 A.
• Charging method . It is better to choose a gadget that can be powered from several sources at once: ordinary electricity and via a USB connector.
• Battery indicator . This element is simply necessary in the daily operation of smartphones and phones. There are several options for displaying the charge: by changing the color or numbers. Numerical indicator much more accurately informs about the battery condition, but also costs much more expensively.
• Number of ports used . Prudent and prudent users choose the specimens with the largest number of them. But, as a rule, the need to recharge several devices at the same time occurs rarely. Therefore, 2-3 ports are enough.

Several features that should be considered when choosing batteries

In addition to the main parameters, which need to pay special attention, there are several additional qualities. They can greatly facilitate and extend the operation of the presented gadgets.

It is best to choose an external battery for the phone, on which the power button will not stand out against the backdrop of the case. After all, if you press it by accident, you can get a pretty nasty surprise. In addition, there will be a special flashlight in the device to make it easier to find in the dark.

In order to protect a valuable thing from getting all kinds of dust or water, and also to protect against small blows, it is necessary to choose devices with a special body. Such devices will cost a bit more, but their service life will be longer.

Lovers of modern innovative technologies will appreciate the presence of such features as Wi-Fi and NAS Server. With their help, you can not only freely use and distribute the Internet, but also save various data on a special memory card.

It will be useful for any battery and solar battery. After all, in the summer we are not always close to any power source.

How to choose an external charger. A few tips

To buy a quality battery that will last long enough, you should approach this issue with all seriousness. Before making a final choice, you need to familiarize yourself with the most common options, compare characteristics and reviews. And only then you can buy a good external battery for your phone.

1. First of all, this device should be convenient enough, light and compact to fit freely in any bag.
2. The charger of the same company as the main unit will do much better than similar analogs. In addition, in this way you can protect yourself from poor-quality goods.
3. It is better to specify in advance whether a return is possible, and under what conditions. The charger may just not be trivial.

Comparison of the most common external batteries

There are many external telephone batteries. There are probably as many as the mobile devices themselves. In this case, everyone selects their external battery for the phone. Feedback - this is what attention is drawn to first. Therefore, here are some subjective opinions about the most popular models:

• The vampire-mini. There is a standard USB connector. It is convenient to adjust the current and voltage. Among the shortcomings is low efficiency.
• Increasing stabilizer. This battery charges almost all known mobile devices, and also charges from any power source. The only drawback is that an external battery pack is required.
• Specialized energy storage "Proglott". Universal battery. It has many special connectors for all kinds of devices, and it is also easy to replace internal batteries in it. Negative - in the absence of adapters.

Universal External Battery

As the world omniscient statistics shows, almost every city resident has two or more mobile devices, as well as a laptop and several other gadgets. Therefore, many are eager to purchase a universal external battery for the phone, but so that it is suitable for the other devices.

This choice allows you to kill several "rabbits" at once: the ability to charge all the available gadgets from one device at the same time, saving money and places. In this case, the operating rules for such devices are the same as for narrow-band batteries. In addition, modern stores can offer a huge number of different in price, performance and quality of batteries. Therefore, this is the most optimal choice for any user.

Homemade external battery for phone

An additional power source for the smartphone is not necessary to buy. If you want and certain abilities, you can easily make a homemade external battery for your phone.

The most common self-made is charging from batteries and from the sun. Each of them has its own characteristics. In the first case, you need a resistor, a suitable plug, 4 batteries and a special box for them. The principle of operation is simple - the resistor connects the nutrients to the plug and transfers the charge to the mobile device. The downside is that the batteries need to be constantly changed.

In the case of solar charging, you can simply buy special flashlights from the sun, and take from there the necessary elements. Then the circuit is connected by means of a diode, and the design is filled in some box.
