What Cyril and Methodius composed. Creation of the Slavic alphabet

September 1 is approaching, and with it the school year. Many parents are already puzzled by the choice of gadgets for schoolchildren. We found out how children's and adult devices differ and what the market of modern digital technologies can offer children in general.

Modern devices are multifunctional and therefore suitable for all family members. But the functionality required by an adult and a child differs, this difference becomes the key point when choosing device for schoolchildren.

Exclusively children's gadgets - this is a small line specialized phones. They are lightweight (weigh about 70-80 grams including the battery), have a minimum of functions and only 5 buttons. Four number buttons record important contacts for the child, for example, the numbers of mom, dad, grandparents, and a child, even a two-year-old, can easily call loved ones. In case of an emergency, there is a “sos” button, pressing which makes a call to all four numbers. Of course, such phones are suitable for the little ones, because... As a child grows up, he needs more and more functions and, as a result, it becomes impossible to distinguish between children's and adult gadgets.

Parents choosing a device for a first-grader should decide on the price category and the desired set of functions. As a recommendation, a smartphone and a tablet will be useful for a beginning schoolchild - a large screen tablet will allow you to avoid damaging your eyesight when working with electronic textbooks and encyclopedias, and a smartphone is necessary in order to always be in touch with your parents. If parents don’t want to “burden” their 7-year-old child with two gadgets at once, a smartphone will be enough, then you should choose a model with a large screen and a good camera - the camera will be useful on excursions, where the child can take photos and videos and immediately share them with friends .

When choosing a gadget for older students, you should pay attention to CPU performance- Children are already actively using the Internet to watch videos, work with applications and listen to music.

We should not forget that children are not the most careful owners of equipment, so it makes sense to take care of shockproof cases and protective films and glass, especially if the selected gadget is quite expensive. Such simple precautions will save the parent's wallet and the student's nerves.

Buying a gadget in Moscow is not a problem; electronics stores are located in every district. However, not everyone has specialized children's gadgets and high-tech toys. A place where gadgets for every taste, age and budget are collected. Central Children's Store on Lubyanka and this is the first Center for Family Digital Technologies “Know-How Kids”.

External battery for phone: selection criteria and methods of 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. Thanks to such applications, any smartphone “sits down” almost throughout the day. Therefore, you need to learn how to choose a more powerful power bank for your phone. Or choose an additional power source.

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

Thus, the phone began to discharge frequently and quickly. Let's start with the fact that it is necessary to determine the root cause, and only then find the most optimal ways to solve the problem. So, what are the reasons for early discharge?

If the smartphone or tablet is new, the instructions talk about a certain operating time, but in fact the device runs several times less, then the reason can be resolved in the settings. Typically, on your phone, you can adjust the brightness and power consumption, or turn off a few apps that are draining the battery.

Another thing is if the smartphone is configured, it worked fine for a long time, but in the end it was discharged much faster. The internal charger or external battery of the phone is most likely to blame here. The only solution is to replace the element. To do this, you can use either a patented battery or a universal analogue.

Types of external batteries

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

Lithium-ion. This is perhaps the most common external battery for charging your phone. It has a more optimal balance of durability, safety and energy consumption than other analogues. In addition, such elements are endowed with a special “memory effect” and discharge slowly. But they get old quickly, even in the case of constant work.
Nickel-cadmium. Recognized as the most harmful and were placed on the shelf. They were only used in the first phones due to their low cost. In addition, the higher their energetic intensity, the higher their physical size.
Lithium polymer. These are cheaper and better external batteries for cell phones. Therefore, these elements took on all the positive aspects of the original selection and also became more environmentally friendly.

Features of operation and maintenance

The mobile phone is quite complex and delicate. And each of its elements has its own characteristics and requires certain operating conditions, including the battery. Therefore, there are several rules that, if followed, can significantly extend the life of your phone battery:

When using, you must strictly follow the operating rules specified by the manufacturer, that is, do not overheat, do not get wet or overcool.
Try to avoid physical damage to the item.
External cell phone batteries do not withstand frequent impacts and drops.
Do not open the battery yourself just for fun.
Replace and charge the battery only when the device is turned off.
It is not recommended to constantly charge the gadget for a long time (more than one day).
The more often the battery is used, the better.

Myths about mobile batteries

During all this time availability of mobile phones almost overgrown with various fictions and legends that scare naive users. Some of them concern the most important part of them.

Parameters to consider when choosing chargers

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

Current battery capacity. This directly depends on the operating time without additional recharging. Typically, 4000-6000 mAh is sufficient.
Current strength. If the battery is used to power more than just a smartphone, you need to choose a device with a power of 1-3 A. For a regular phone, equipment that produces 1 A will be sufficient.
Charging method. It is better to choose a gadget that can be powered from several sources at the same time: regular 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. A digital indicator provides much more accurate information about the state of the battery, but also costs much more.
Number of ports used. Reasonable and prudent users choose samples with the greatest number of them. But, as a rule, the need to recharge several devices at the same time rarely occurs. Thus, 2-3 ports are enough.

A Few Features to Consider When Selecting Batteries

In addition to the basic parameters that need special attention, there are several additional qualities. They can significantly facilitate and expand the work of the presented gadgets.

It is best to choose an external battery for your phone, on which the power button does not stand out from the background of the case. After all, if you click this by accident, you could end up with a pretty nasty surprise. In addition, the device will have a special flashlight to make it easier to find it in the dark.

To protect your valuable item from receiving all types of dust or water, as well as to protect it from small impacts, it is necessary to choose devices with a special body. Such devices will cost a little more, but their service life will be longer.

Fans of modern innovative technologies will appreciate the presence of functions such as Wi-Fi and a 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.

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

How to choose an external charger. Some tips

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

First of all, this device must be convenient, light and compact enough to easily fit into any bag.
A charger from the same company as the main unit will be much better than similar analogues. In addition, this way you can protect yourself from low quality products.
It is better to indicate in advance whether a purchase is possible and under what conditions. The charger simply cannot be trivial.

Comparison of the most common external batteries

There are many external phone batteries available. Most likely, there are mobile devices. In this case, everyone chooses an external battery for their phone. Feedback is what attention is paid to first of all. Therefore, here are some subjective opinions about the most popular models:

Vampire mini. There is a standard USB connector. Convenient to adjust current and voltage. Disadvantages include low efficiency.
Increase in stabilizer. This battery charges almost all known mobile devices and also charges them from any power source. The only downside is that an external battery is required.
Specialized energy storage "Proglott". Universal battery. It has many special connectors for all kinds of devices, and the internal batteries are easy to replace. Minus. in the absence of adapters.

Let's not fuss - there are many schoolchildren among our readers. Not a predominant number, but schoolchildren and students are a good (in the sense of large, not kind) part of our audience. And now that blessed time has come, which all salespeople simply call “Back to School” (B2S). In a simple translation from the language of marketers into universal human language, this means “the time when people waste money.” Everyone needs notebooks, backpacks, forms, bows, pens, so many things that it’s time to grab your head. Marketers need to encourage you to make purchases in a way that is more profitable for them, and your task is to spend wisely without a terrible blow to your budget and taking out loans. At the same time, there are three main expense items: office supplies, clothing and shoes, and equipment. If you are able to choose the drawings for notebooks yourself, just like the style of the jacket, then buying equipment is not an easy matter. Today I propose to figure out what characteristics a gadget for schoolchildren and students should have and look at the most suitable options.

As usual, I asked our readers for their opinions in the VKontakte group and on my Twitter page. I’ve read all sorts of different comments, you can read more yourself check out the link ke or , but the conclusion is approximately this: students need a laptop or tablet with a keyboard, and schoolchildren need a folder belt. Other popular options are “brains” and “notebook”. Somehow everyone unanimously agreed that schoolchildren do not know how to be careful with technology, and if you give them something more complicated with a slide rule, they will constantly hang out on the Internet, play games and completely forget about their lessons. Typically, such things were written by yesterday’s schoolchildren.

Experts, what can you say, which gadgets do schoolchildren need and which do students? Why?

I have more faith in the younger generation, so I still think that schoolchildren also need devices. My opinion may seem too conservative to you, however, a student’s gadget kit, according to Yulia Ryabukhina, will consist of a simple push-button dialer + tablet; a student will need a tablet with a keyboard and an OTG cord or an ultrabook + smartphone. We won’t touch all these cables, headphone splitters, memory cards, mice and other small details today, this is optional, but let’s deal with tablets/laptops.

For what?

Actually, it is this question that you, students, will have to answer a hundred times. It’s like approving a budget for some project - you need to be very detailed and convincing, otherwise they’ll start talking about dad’s belt and notebook again. So, there are a couple of arguments in your favor:

all textbooks/notes in one device
it has a backlight (in case the lighting is poor or for reading on the go)
relief for the back
find information easier and faster
quickly edit diplomas/coursework, etc.

Here in our editorial office the opinion is divided, just as on the Internet - does a schoolchild need anything other than a dialer? Nowadays, parents send their children to elementary school with a smartphone, which I only got when I reached adulthood, but in fact, he doesn’t need it. It's just a distraction. On the other hand, it’s good if you have a direct channel of communication with your child - you can always dial, find out how things are going, and check. For some reason, high school students are also schoolchildren. I remember my backpack in 7-8 grade. I had 8 lessons, one textbook of Russian literature weighed as much as the globe, and every day I had to carry several of them on my back. In general, my backpack weighed a lot, and no parent wants scoliosis or a bad back for their child. So if it is possible to pack all the textbooks into one tablet or smartphone, it is better to do so. If, of course, all the teachers understand that this is possible and do not demand from the student “a paper book, but without it, it’s a bad job.” It is also better to clarify this point with teachers.

What to pay attention to

If a child (it doesn’t even matter whether he is a student or a schoolboy) asks for a camera in a smartphone/tablet that is better than a very bad one, it is not at all necessary that it is for a selfie at the last desk during lessons. A camera is needed to photograph schedules, notes, and printouts. In general, we have collected requirements for gadgets for students from us who have already graduated, so if you missed something, leave it in the comments and we’ll add it.

dimensions— the device should not be heavy, because everyone needs to go to school/university with it, and it should not have the smallest display so that it can be read comfortably. Therefore, when choosing a tablet, I set a criterion of 9 inches;
materials and security— for older children this may not be the main criterion, but very young children are very active, so a smartphone can easily fall out of a pocket during tag or a snowball fight, for example. Therefore, impact resistance would be very useful;
display quality- very important to reduce eye strain. What it will be - E-ink Paper White or regular IPS is up to you to decide, but the higher the pixel density, the better, and E-Ink is generally gentler on your eyes;
autonomy— it is necessary to survive as long as possible with the display turned on. So that there will be enough for lessons and, perhaps, for afterwards;
it was possible to connect peripherals- flash drives, mice, phones, burn discs (and teachers still use this!), external monitor or projector, dump information, edit, show presentations and stuff like that. That is why the majority of the editors voted that the student needs a laptop - there are more ports of all kinds. Let the tablet sit at home and let parents watch TV series on it;
camera— photograph the schedule, notes;
price- Well, there’s no need to explain here. As one of the commentators wrote, “Everything is limited by the mother’s budget”;
technical specifications- only if the specialty requires it, engineer, web designer or something like that.

Actually, gadgets

Smartphones

We won’t dwell on anything in particular here, wait for next week’s material, where we will look at what you can really buy good with a budget of up to 3,500 UAH (160 dollars), which will tell you what to choose, and at the same time put out everyone who is burnt.

Tablets

Lenovo Yoga Tablet

This is just what the doctor ordered. Especially if it's 10 inches. I remember my impressions of this tablet - mommy, I’ll keep it! It works for an unrealistically long time, the display is large and of high quality, the backlight is generous, the camera is even tolerable, although it’s in a very stupid place. But it is light, and autonomous, and large, and metal, and this is exactly the first thing I thought about when I compiled the list of requirements. In addition, it is three-position. There is also a keyboard for it. In short, it's just a dream. True, the price is not the most budget-friendly for the dream - 6300 UAH or 285 dollars. But it's really worth it.

Onda

I discovered Android iPads from Onda. If you don’t have money for a real iPad, your child has a strong character and is generally not very good with technology, you can buy him this. Honestly, I didn’t hold it in my hands, but judging by the description and reviews, it’s a little more than justifies its 220 dollars (and now you can find it at a discount for 170, model ONDA V989). There are several types of tablets, but they all turned out to be sensible. In terms of performance, the gadget is even compared to, so you can pull it and drive it into hairpins yourself. But it's really a copy of Apple gadgets.

Prestigio MultiPad 4 Quantum 9.7

In the previous article, everyone was very unhappy with the absence of this brand. The axis is for you, as they say. Simple, not for entertainment, but for work. The price seems reasonable, the density is ok, there is a camera. A little heavy for its size, this is bad, the processor is weak, not for games, which means there is less temptation.

Apple iPad

Everyone loves iPad. The second, third, fifth or tenth - that's enough money for that. The first is the most affordable in price, but a little heavy, the second is amazing - my love, the third is needed to play tanks with Lyapota, so if the budget allows, it is better to choose a middle ground. The iPad has a cool display, good parameters, and better cameras than many Android fart smartphones.

Nokia Lumia 2520

The only Windows tablet on this list. In case the parents, ala Kremenyuk, are Microsoft nerds. Here, in principle, everything is very, very good - display, size, battery life, very good camera. In short, it’s good for everyone if the child is not yet accustomed to the fact that the morning begins with Gmail, Chrome, etc. He also knows how to handle glossy plastic, which slips and gets dirty. The gadget is visible and fast, and if you are not convinced of this yet, you can. The price, however, is a bit wow - $350. At this point you’ll start thinking hard: “Maybe the iOS device is better?”

ASUS MeMO Pad FHD 10

This model is so old that Igor Souchon himself made something like this in 2013. So much water has passed under the bridge since then, but I still say that it’s not worth paying attention to if you’re looking for something simple, average and on Android . 10 inches, weight 580 grams, 224 ppi, battery life is acceptable, although the camera is not the coolest, but the price is reasonable - $220. In general, you can take a closer look.

Laptops

I chose four examples for greater clarity: expensive and cheaper laptops, a netbook and a transformer. With laptops, it’s better to pay attention not only to the price, but also to the weight and characteristics, but with netbooks in this regard it’s a little easier, there, I think, anyone is suitable if the budget stretches it.

Dell Latitude 3340

On the company’s website it says so - Latitude 13 Education Series, that is, you don’t need to invent a bike yourself, but just look at the characteristics, dimensions, weight of 1.8 kg (a lot, but this is a girl’s comment), a comfortable keyboard, many ports and connectors. Here you can find from 600 dollars, although the official website says from 539 for the basic package.

Acer Aspire ES1-311-C08G

13-inch typewriter. Users note its thinness and lightness, and those who paid for the purchase will also approve of the price. In some stores it has dropped from $300 to $250, which is nice. You won’t be able to work in the “Work hard don`t stop” mode—not the most productive kid. Several browser tabs and documents are what he needs.

ASUS EeeBook X25TA0

What is called budget, compact, convenient and easy. If you've already written off netbooks, you've done it in vain. We really need one that can handle documents and some kind of PowerPoint, right? So why pay more? Here Anton Poznyakov tells in detail what life with a netbook is, and what else.

ASUS Transformer Book T100TA

A little more than a budget gadget for university. It will fit into any backpack/bag, won’t break your budget, meets all requirements, and is also transformable. That is, you need to type - a laptop, if not - a tablet, you can watch a TV series during recess. It also has impressive autonomy. In addition, depending on the budget, there are also varieties of transformer books - which Anya Lyapota still uses, which I wanted to keep for myself. The Chi line is generally instantly addictive and you can choose the appropriate diagonal.

On the same Hotline there is a whole section of laptops, which is called “For Study”. Prices, however, start at $300, so if your budget is even more limited, it’s better to immediately look at the tab with transformers or netbooks, especially since they are enough for studying. And answering the question “Is a tablet or laptop better for a student?”, we honestly say: “Laptop.”

Epilogue

So you can safely show this material to moms, dads, grandparents, or whoever is in charge of the budget in your house. I tried to choose equipment that didn’t break the budget and that best suited the chosen parameters. This is a kind of frame, and from it you can dance into any variety. Of course, all this works as a distraction, and the scourge of the modern generation is precisely absent-mindedness, so there is a chance that instead of a textbook, a student will open a toy, chat or movie. But this is everyone’s conscious choice. The parent has several ways out of the situation: talk to the child and explain why basic education is important, master the “parental control” function, sit and worry, or not buy the child what he needs for school.
