The proliferation of high-performance smartphones equipped with weak batteries is forcing users to seriously think about alternatives. Unfortunately, convenient solutions for everyday use, other than conventional batteries, does not yet exist. The only decent option is stand-alone power units for charging your phone without connecting to the network. But such options have a lot of disadvantages. At the same time, for those who like to spend time in nature and away from civilization, a capacious Power Bank. In such situations, a solar battery for charging your phone comes to the rescue, which is completely independent from the mains. Such devices allow you to replenish the charge mobile devices, receiving energy directly from the sun. Accordingly, this is also free way ensuring the functioning of electronics.

Battery design and principle of operation

In design, such products resemble small batteries, the peculiarity of which is a wide range of various adapters. The standard device includes photocells that accumulate energy, which is converted into a power charge. Next, the energy is supplied to the mobile device via miniUSB or microUSB. Depending on the model, such devices may be equipped with special indicators, the glow of which indicates a sufficient level of light to complete the charge.

Before you start powering your phone, you should charge the solar battery. This may take several hours, depending on the brightness of the light. After this, the solar battery for charging the phone can be used for its intended purpose. Having selected a suitable adapter, you can connect the battery to the target device.

Main characteristics

The main characteristic is power, which averages 4-12 W. This indicator is enough to work with small mobile devices, but it is better to charge a tablet or laptop with more powerful batteries. In this case, the solar battery device may include several elements of the NiCd-NiMh type. Accordingly, the more batteries, the faster charging will be carried out, but the weight of the device will also increase significantly.

By the way, the dimensions of such devices rarely exceed the size of a video cassette, and the weight is usually 400-500 g. But there are exceptions, and if you are planning a long trip, it is advisable to initially calculate the mass additional source nutrition. If you plan to use the device as a standard adapter, then the solar battery for charging the phone must also be able to connect to an outlet or cigarette lighter.

Charging efficiency

Still, the majority of buyers count on the possibility of operating solar panels in a mode of complete autonomy relative to the power grid. That is, the question arises of how effective, in principle, charging from an alternative source can be. As practice shows, the battery charge is completely recharged in 6-10 hours. Such a wide range of times is due to the fact that the sun can have different glow parameters. It is clear that under the most favorable conditions, this charging method will lose out to power supply from an outlet, which takes an average of 3-4 hours. When charged, a solar battery for a phone can provide power to the phone for 1-2 hours. For a low-performance push-button device, this time is quite enough for complete energy replenishment. However, modern smartphone models with large screens and capacious batteries often require much longer charging time.

Battery cost

The simplest elements with low power are valued at an amount not exceeding 1 thousand rubles. As a rule, these are Chinese devices of dubious origin, among which, however, you can find very effective options. The price tag increases as the functionality of the solar battery increases. The price of devices that have a wide range of adapters and connectors can be 2-3 thousand rubles. Of course, in this case the power will be at least 10 W. The most expensive models of solar batteries cost 4-5 thousand rubles. and more. Such devices can no longer be called compact, since the equipment may include a display, a wide range of ports and plugs, as well as special fasteners. With the help of such a complex you can recharge not only your phone, but also a full-fledged laptop.

Positive reviews about solar panels

Most of the laudatory opinions regarding the use of solar panels come from users who specifically purchase such devices for outdoor use. It is precisely in conditions of separation from civilization that one can highly appreciate the benefits of an alternative energy source - independence from an outlet is the main advantage that almost all solar panels have. Reviews also note the versatility of such devices. For example, in addition to being powered by the sun, the batteries can be connected to a regular electrical outlet and subsequently used to charge a mobile device one-time.

Negative reviews

Most solar panel manufacturers are represented Chinese market with all the characteristic disadvantages of such products. Experienced electronics users note that, in essence, the basis of batteries is unfinished photocells. That is, such panels are nothing more than blanks for more complex devices. At the same time, the low technological level goes against the price tags. The fact is that even the average cost of solar panels is 1-2 thousand rubles. in most cases it is unreasonably high. For comparison, only in rare cases do they cost more than 1 thousand rubles.

How to choose the best option?

In order not to miscalculate when purchasing a solar battery, you should initially determine the level of required power, connectivity options, and the size of the device. The optimal power level for a medium-performance model is 3-4 W. In terms of connectivity, a solar phone battery should, at a minimum, support the USB and microUSB interfaces that most modern mobile phones interface with. In terms of dimensions, the choice is made individually, based on the nature of the operation of the device.

Conclusion

The world's major manufacturers are not yet striving to fully develop and market chargers based on solar photocells. Therefore, the niche is occupied by little-known and, as a rule, small companies. One way or another, the solar battery for charging the phone has no competitors on the market that can replace its function. The same ones are only good as a way to perform 3-4 power sessions, after which they themselves need to be connected to an outlet. In turn, solar batteries can operate for weeks and months in complete autonomy, providing power from photo panels.

More and more connoisseurs of active recreation prefer to spend their holidays and weekends closer to pristine nature. But it is difficult for a modern person to refuse the benefits of civilization - who among us does not take a mobile phone, laptop or camera on a trip?

But if in your luggage there is Charger on solar powered, the problem with powering the devices will be solved. All that remains is to figure out how to choose the right device. The article we present will provide effective assistance in clarifying all issues.

These chargers are capable of converting solar energy into DC electricity. They can work with various models navigators, players, laptops, phones, cameras and other portable devices.

But the charging time directly depends on the power of the device itself and the type of discharged device, therefore, in order to choose a truly practical and universal device, it is worth understanding its characteristics.

Design features of the device

The device itself consists of a crystalline panel, a charge/discharge level controller and a solar-to-electric energy converter.

Some models are also equipped with a buffer battery consisting of several lithium cells, which allows the device not only to convert, but also to accumulate energy in order to release a charge even in the dark.

Just a couple of years ago, solar chargers were quite expensive devices, but today they are a mass product with an affordable price

Advantages of solar chargers:

• Universal - adapted for various devices (USB connectors are provided on the case, and most models are additionally equipped with special adapters for different kinds electrical engineering).
• Takes up little space in travel luggage.
• There is a wide selection of shapes, colors, sizes and power to suit different needs and aesthetic tastes.

Well, the most significant drawback for all solar chargers is the long time it takes them to accumulate “power”. In addition, it should be understood that if almost any model can handle powering a mobile phone or camera, then an active “absorber” of energy such as a laptop will already require impressive power from a solar battery and a capacitive battery.

How the device works

Portable solar-powered chargers are autonomous systems that can process energy both from rays and from the mains, fluorescent lamps or a computer. Moreover, many models do not necessarily need to be exposed to intense sun - they accumulate charge even in cloudy days, although the efficiency, of course, drops (from 20 to 70%).

If you buy a device with the ability to connect to an electrical outlet, you can significantly save time on accumulating charge in cloudy weather

The device works like this: crystals on the panel absorb solar energy, the converter “processes” it into electric current, which is supplied to the power source. When a mobile phone or other device is connected to this source using a cord, the accumulated energy gradually flows into the discharged device.

Types of solar chargers

As for the appearance, manufacturers have already tried not only to diversify the color scheme and shape of the devices, but also to make the device as convenient as possible for use in various situations. Let's look at the most popular options.

Monoblock– a compact device consisting of a panel and a drive enclosed in a solid metal or plastic case. Such a device will “save” a discharged phone on the beach or a picnic and will not take up much space in a regular bag.

Monoblocks are convenient for everyday life - they do not take up much space and can be charged not only from the sun, but also while working on a laptop or computer

Flexible panel– a thin folding or unfolding panel with photocells. It takes up little space in your luggage, and it weighs much less than its solid, enclosed competitor. But, despite the decent “coverage” area, they accumulate solar charge almost twice as slowly as monoblocks.

In addition, most panels operate only from direct sunlight, without storing energy for future use - they do not have a built-in battery. However, you can always upgrade your charger external storage required power.

So flexible panels are a good option for solving the problem of recharging low-power devices during a “stationary” vacation - in the country, fishing, with a tent. But for a hiking trip, it’s better to look at another option.

While driving, the flexible panel can be compactly folded and placed in the trunk or attached to the roof of the car, and at a rest it can simply be spread out in the sun.

Built-in charging– the device consists of devices that are attached to the outside of bags or backpacks. They allow you to recharge devices while traveling or store charge in the built-in battery.

This accessory can also be used for its intended purpose - to carry any objects or electronics, which is very convenient for those who are keen on hiking or working outdoors.

Although “energy backpacks” look attractive and stylish, you can just as easily temporarily attach any other type of charger to your bag (many models are even equipped with special carabiners) and not worry about the safety of the device during rain or cleaning

Folding beds– these can be either several flexible panels, compactly folded in a “stack”, or a variation of two monoblocks enclosed in a rigid case in the shape of a drop-down book.

The main goal of such a device is to minimize the “capture” of usable space in the volume of your luggage and increase efficiency due to a larger number of photocells. A nice bonus is that most models are equipped with mounts for a backpack or car window.

The size of the clamshell can be selected based on your needs: to charge a mobile phone, a device the size of the phone itself is enough, but for laptops and tablets the panel even when folded will not be less sheet A5

But regardless of the design, all solar chargers work on the same principle, so let’s look at important technical nuances that will help when purchasing a device.

How to choose the right option?

First, you should decide on the number and types of devices that you plan to charge using solar charging. The power of the device and the type of output port depend on these parameters.

If the device has several USB ports, you can simultaneously connect and charge various devices, the main thing is that the battery power allows it

The characteristics of various devices can be clarified by looking at their operating instructions, and in some devices the operating voltage is also indicated on the charger that is included in the kit, so it will not be difficult to navigate. As a last resort, required adapter You can always buy more.

Basic parameters and nice additions

The characteristics of the charging current determine the time it takes for the device to recharge various devices. This indicator is measured in amperes and is indicated on the ports of the device.

Values:

• 1 ampere – intended for mobile phones, electronic cigarettes, watches, players.
• 2 amps – suitable for tablets, smartphones, digital cameras and video cameras.
• 2.5-3 amperes – will cope with charging netbooks and laptops.

It is also important to know the output voltage, because the devices being charged can exceed the power of solar charging. Yes, for most phones and simple tablets you will need an output of 5 volts, for digital cameras and gaming gadgets – 9, and for laptops and car refrigerators – 12-24.

But still, the main characteristic of the charger is the power of the solar panel. The battery charging time directly depends on this indicator. And here it all depends on the characteristics of the light-collecting panels.

For example, elements with a power of 5 W (standard budget option) will have a current of 900 mA hours, and 10 W will have a current of 1500 mA. That is, to charge a phone from a 5 W solar charger, it will take 2-3 hours, but a 10 W panel will do it in an hour and a half.

For powerful devices such as gaming tablets and laptops, it is better to buy folding models with several panels that quickly generate a charge

In addition, devices with panels whose power does not exceed 2 W are used only to accumulate charge of the built-in battery. And to directly charge devices from sunlight, you need panels with a power of 3 W or more.

Other important parameters:

1. Battery availability– if the device does not have a storage device, it can only work while in a lighted place. Devices with batteries can supply charge at any time of the day, and can also be charged from other sources - a laptop USB port or an outlet connected to 220V.
2. Type of photocells– it is believed that single crystals absorb sunlight more effectively (their efficiency is 13-18%). For polycrystals this figure is lower - about 10-12%. You can even distinguish them with the naked eye - polycrystalline panels have a dark blue tint, while their competitors are black.
3. Interface – universal chargers from the sun are equipped with informative USB, where you can select the desired option depending on the type of discharged device. Some devices are also equipped with an indicator of the intensity of sunlight, which will help determine the optimal location for a quick charge.
4. Protection– a priori, all devices have a security system that allows them to be used outdoors. But for lovers of extreme adventures, it is worth looking for a device with enhanced protection from rain, dust, dirt, shocks and other force majeure.

Additional features are most often represented by the “lantern” or “lamp” function. This may be relevant not only for lovers of outdoor recreation, but also for motorists - when changing a tire or making repairs on the road at night, a bright light will become an indispensable assistant.

Among other bonuses, manufacturers may offer a USB hub or Wi-Fi hotspot. But, of course, any additions significantly increase the final cost of the product. Whether they are really needed is up to you to decide.

Devices with a built-in battery must be fully charged before first use, not in the sun, but from the mains. Then connect any device to the charger so that it receives energy and discharges the drive.

After this, the panel can be exposed to the rays and compensate for the lost charge. For models operating directly from the sun, this rule does not work - they can be immediately installed in illuminated areas and connected to devices.

Most solar chargers are designed for operation in temperatures ranging from – 20 to + 45 degrees, but there are also special models that operate in extreme climates, only they are made to order

To maximize solar charging efficiency, we recommend the following:

1. Position the device so that the rays fall on the panel at a right angle. Even if the sun is not at its zenith, you can give the charger the correct position by lifting it at an angle of 40 degrees with the help of some kind of support. This way you can collect 20-30% more charge than if you place the panel horizontally in a lighted place.
2. Use the device together with a storage device, not only at rest stops, but also while traveling by car or on a hike. Such a tandem will be able to collect energy for 2-3 phone charges even in cloudy weather without direct sunlight.
3. Keep in mind that in most folding devices the panels are connected in series, so it is important that all elements are evenly illuminated. For example, even if the shadow covers only half of the first of four panels, the battery power will drop by half.
4. To batteries large capacity reached the stated parameters, it is recommended to “overclock” them - completely discharge them, then charge them to 100%. And so 3-4 times.
5. During a long break in operation (a month or more), store the charger at room temperature. If this is a device with a built-in battery, it must first be charged to 50-70%.

And the last piece of advice - even if the charging has become worse or has completely broken down, do not disassemble it yourself, so as not to damage the system elements and the case itself. A disassembled device is automatically removed from warranty, so it is better to contact an authorized service center or to the supplier.

How to make a charger with your own hands?

Although modern chargers have ceased to be premium devices and are quite affordable for the average consumer, if you want to save money, there is always the opportunity to make such a device yourself.

Example homemade device in a rigid case made of a metal can, equipped with a USB connector and an energy converter for charging low-power devices

To make a simple solar charger you need to purchase several basic elements:

• poly- or monocrystalline panel;
• battery holder;
• Schottky blocking diode;
• connector socket;
• charge controller (however, if charging produces 0.5-5V, you can use a cheaper 5V boost converter instead of the controller).

As for the panel itself, here you need to make a small calculation of the number of elements, based on the power of the device that you plan to charge.

For example, if the charging current for the battery is about 10% of its capacity, then charging at 20,000 mA requires a current of 2A, and it will take about 14 hours to power the device. If you double the current to 4A, the charging time will be reduced to 7 hours.

Replacing the controller with a converter will allow you to assemble a charger even using a low-power battery from a solar lawn lamp - you will still get the required 5V output (although it will take a long time to charge)

Depending on the current parameters for future charging (2 or 4A), crystalline elements are also selected. Typically, 1 part produces about 0.5V, that is, to get at least 5V you will need 10-12 elements.

Then they need to be soldered together in series. If you use a flashlight panel, then even a standard 70*70 cm can output from 2.5 to 4.5V, so it’s better to check with a voltmeter.

The final stage is to enclose the homemade charger in any suitable frame (even a candy jar will do) and equip it with a USB connector. Then you need to solder a blocking diode to the connector, as well as wires from the solar panel to the converter and holder according to the diagram below.

A Schottky diode is necessary so that when the device is turned on, the batteries are not discharged through the solar panel. You can purchase it, like other components, on radio markets or on the Internet

All that remains is to check the operation of the device in the sun with any discharged device. If everything is in order, you can use the appropriate adapters and charge various devices.

The rules for selecting solar panels for arranging a private home or cottage will be discussed in this article dedicated to this interesting issue.

How to choose a solar battery for your phone?

There are many phones on the market today with high performance and small capacity batteries. Therefore, in order not to be left alone with a discharged smartphone, many users are thinking about purchasing an additional power source that can be used on the road. Nowadays there are many different external batteries. But there are very few truly convenient solutions. After all, the portable power source itself also needs to be charged. As a rule, such batteries are charged for 8-10 hours until they reach full capacity. And this is from electrical network, and through USB charging will take much longer. In addition, many people like to go out into nature, go hiking, travel, etc. And in such conditions it is extremely difficult to find an outlet. In such situations, an external solar battery can be very helpful. This is an autonomous battery that will charge your phone anywhere, and will replenish its charge from the sun's energy. Among other things, this is also a free way to replenish the energy of mobile electronics. As you may have guessed, this review will focus on solar-powered batteries for phones and other mobile equipment.

In my own way appearance Solar batteries resemble regular portable batteries. This is a small box with an indicator and several ports. As a rule, the package includes many different adapters for charging mobile devices. But they have one feature. These batteries have built-in photocells. They accumulate solar energy and convert it into charge. Solar batteries have a mini USB or micro USB interface designed to transfer electrical energy to a mobile device.

Most consumers expect that the use of a solar battery will be completely autonomous and will not depend on an outlet at all. In this case, the question of the efficiency of charging a phone from a solar battery is relevant. The process of charging a full battery capacity takes from 6 to 10 hours and depends on the intensity of the sun. Even under the most favorable conditions (a clear sunny day), this charging option lasts longer than from the electrical network. The latter option takes from 2 to 4 hours.

A charged solar battery can recharge idle time. push-button telephone in 2 hours. If charging modern smartphone, then it will take significantly longer to fully charge. As a result, the charging time will depend on the capacity of the phone’s battery and the current provided by the external battery port.

Basic parameters of solar batteries

The key parameter is power. The average solar battery has a power value in the range of 4-12 watts. In principle, this value is sufficient to charge a phone and other small gadgets (smart watches, music player). But if you are planning to charge a tablet or laptop using the device, then it is better to look for a model with more power.

As for the filling of a solar battery, it can be , and or . They are in the assembly as in batteries for laptop. The more battery cells and the capacity of the device, the more charge accumulates, the more devices a particular model can charge. The downside here is that as the assembly elements increase, the weight of the device and its dimensions increase.

In size, most solar batteries correspond to a video cassette, if you still remember such storage media. The mass of solar batteries is about 0.5 kilograms. There are models with larger capacity and weight. It’s up to you to decide, since on a hike such a “brick” in your backpack will be burdensome. It is highly advisable to choose a solar battery that has the necessary interfaces and adapters for charging the device from car cigarette lighter or electrical outlet. It won't be superfluous.

Price of solar batteries

The simplest low-power models will cost the buyer about 1 thousand rubles. But the quality in this case leaves much to be desired. Cheap devices from China are usually sold in this price category. But if you try, you can find simple and effective solutions.

The price of a solar battery increases as the set of functions increases and the equipment included in the device increases. If you have a large set of cables and adapters, the price will be about 3 thousand rubles. The power of such devices will be at least 10 watts.

Solar batteries in the upper price category have a price tag of approximately 5 thousand rubles. These models are quite large in size and weight. They come complete with a large set of cables and adapters, and various additional accessories. Some devices are equipped with a display. Often these multi-function batteries allow you to charge tablets, netbooks and laptops.

Pros and cons of solar panels

pros

The main advantage of solar batteries is the ability to charge your phone in nature. While somewhere in the mountains, you can safely charge your phone without an outlet. Users who have purchased a battery for such purposes are usually completely satisfied with the alternative energy source. Among the advantages, many owners of such devices note the versatility of solar panels. In most cases, in addition to charging from the sun, they can be charged from the mains. And then they charge the phone. It turns out that solar batteries act as a standard power bank.

Minuses

The disadvantages include the huge number of Chinese devices that have flooded this segment. Experts believe that Chinese solar batteries are produced using low-quality photovoltaic cells. Often such solar panels are semi-finished products for the production of more complex equipment. Often such solar panels are sold at an inflated price that does not correspond to their quality. For a Chinese battery, the price of 2 thousand rubles is too high, experts in this field say.

Examples of external batteries for a solar-powered phone

Let's look at some examples of solar powered batteries from different manufacturers. We tried to take devices from different price categories so that you have an idea of ​​what is on the market.

This model is splash, shock and fall resistant. Perfect for travelers and lovers of extreme recreation. The solar battery has a charge indication.

• The design of the Torch 250 solar battery has good strength and durability.

Solar battery for charging your phone, tablet, laptop is quite easy to assemble. You will need affordable and cheap components.

There is no need to reinvent the wheel. Factory products consist of 5-6 volt mini-cells, a charge controller and a built-in battery that stores energy. The electrical connection between the individual elements is made through Schottky diodes. These low resistance diodes p-n junction necessary to prevent leakage reverse current between two battery cells.

So, you just need to have:

• several solar panels;
• the same number of Schottky diodes;
• mini USB cable or other cable suitable for connecting to the device being charged;
• charge controller;
• battery with as much capacity as possible.

In order for your mobile phone to reliably charge when the sun hides behind the clouds from time to time, you will need to assemble a panel with an output current of 1000 mA at 5–6 V or 300 mA at 12 V. The more powerful the solar generator, the less you will depend on the open bright sun.

A solar battery without a controller has one drawback - it can drain your phone instead of charging it. In bad weather, the voltage at the output of a homemade device may become lower than that of a mobile phone battery. It’s unpleasant, but current will flow from an already discharged battery to an incorrectly assembled generator.

A car phone charger converts the 7-30 input voltage to a stable 5 volts. Such a device can be used in a homemade project as a charging controller for a phone or tablet.

Yours, collected with my own hands, the alternative energy source produces less than 5 volts. Then use a boost voltage converter. Even if half a volt is generated, then with a step-up stabilizer you can get 5 V. Thanks to it, you can use weak black sockets from garden lanterns. It is possible to assemble a solar battery from transistors. True, transistors in generator mode produce a very weak current, so the phone will charge for at least a week.

You need to solder the assembled battery to the voltage converter directly, without using diodes.

To prevent the converter board from dangling, glue it to the back of the solar panel or push it into its original case.

It is convenient to use a bent one as a stand for a homemade solar battery. bank card or a business card made of thick cardboard.

Having various adapters, you can charge any mobile phone or tablet from a homemade charger.

Now you are independent from outlets, and can enjoy the conveniences of civilization outside the city, in nature, for a long time.

As for costs: one 100 mA solar cell will cost 3–5 dollars, prices for automotive voltage converters start at 2 dollars, and you can actually do without a built-in battery.
