This will enable you to save time.

A solar charger is characterized by the presence of advantages and disadvantages, which must be taken into account when choosing it.

What is solar charging?

When going on a hike along tourist routes, it is necessary to solve the issue of charging mobile devices - a phone, smartphone, laptop or tablet. In the absence of available power sources, a solar charger for mobile gadgets will help solve the problem.

The ability to use an absolutely free and inexhaustible source of energy is attractive in itself, and when there is an urgent need for this, interest in such devices increases many times over. Let's take a closer look at the solar charger.

Solar charging is an attractive and convenient way to keep mobile devices running while away from conventional power sources. For this purpose, specialized devices have been developed that convert solar energy into electric current that feeds the batteries of a telephone or other similar device.

Solar chargers allow you not to carry a stock of heavy batteries with you on a hike, providing energy to mobile devices even on cloudy days, albeit with less efficiency. Externally, this is a portable device, the size of a medium-sized tablet or slightly larger (depending on the specific model or manufacturer).The solar battery for mobile phones is lightweight, which will not create unnecessary burden and will not take up much space in the backpack.

Tourists, people working in the field, appreciated the possibilities of portable solar chargers. Modern means of communication have a wide range of gadgets - GPS, echo sounders, video and photo cameras, radio stations - they all need an upgrade in the power source, and the ability to use solar battery charging is a significant help to the traveler.

Design features of the device

The main element of the device is a solar cell that captures light and converts it into an electrical signal. A solar-powered charger is able to supply voltage directly to the battery of a phone or power bank, or store energy in its own batteries, which allows you to increase the speed of charging your gadget.

There are solar batteries for recharging mobile devices, or separate solar panels for charging that do not have built-in batteries. All options have a certain power and are designed for use in certain conditions.

The main elements of the device:

• crystalline elements that capture solar energy;
• charge controller;
• converter that converts solar energy into electricity.

The presence of buffer additional batteries changes the purpose of the device, making it a full-fledged external battery for a solar-powered phone, which has the ability to self-recharge. To use such a device, the presence of the sun is not necessary, you can charge your phone at night.

The main thing is that the batteries have time to get enough energy.Portable charging with a solar battery is equipped with a conventional USB connector, most models are equipped with adapters for different types of connectors.

The principle of operation of the device

The principle of operation of the device is to receive solar energy by crystalline elements, transfer it to a converter, from where it is fed either to a buffer storage (built-in battery) or directly to a consumer device - a phone, laptop or other gadget.

Modern crystalline elements are able to receive light energy not only from the sun, but even from fluorescent lamps. They can work on cloudy days, but the efficiency is noticeably reduced. This versatility greatly expands the capabilities of solar chargers, allowing them to be used at night or in difficult weather conditions.

How not to waste solar energy?

Duo Solar + Powerbank

The energy generated by a solar panel is not constant. Therefore, you should try to use it as much as possible.

For this, the “battery-power bank” bundle is best suited. The fact is that often the battery gives more energy than the smartphone, charger, etc. consumes. Part of the energy is not used. And when the battery of the device is charging, it will automatically turn off. And then all the energy goes nowhere. The same energy, which is then so lacking in cloudy weather.

It is worth making it a rule to always keep a connected Powerbank in the solar battery, which will absorb excess energy that is not used by other devices.

And then, in the evening, give it to devices that have managed to recharge.This is convenient, in particular, for photo and video shooting: during the day, the camera batteries are “in business” and there is no way to charge them. But in the evening and at night they can be "refueled to the eyeballs" so that in the morning they are again in full combat readiness.

Overview of the best modifications

The Russian market has a wide range of chargers that receive energy from the sun. However, only some of them are in demand. For example, we present you the most popular modifications:

Separate solar panel for devices

In some cases, it is possible to charge mobile devices using solar panels, but to achieve efficiency, it must be a separate high-quality battery, usually foldable for easy transportation and storage in field conditions. Such photocells have increased power and are able to charge not only Power Bank, but also mobile phones, tablets, batteries directly.

Review: Charger Solar Charger Power Bank 8000 mAh - Wand - lifesaver under any weather conditions

Good day! Today I want to talk about the charger solar charger power bank 8000 mAh. And yet we could not resist and also bought a power bank. If we gave our Coosen Power Bank 20000 mAh to our parents, then we decided to buy ourselves a slightly different one and, in my opinion, already more reliable and improved, although a little weaker than that one. So, solar charger power bank 8000 mAh

Naturally, like the previous one, it is suitable for charging absolutely any device.

There were no instructions for it, everything is indicated on the package. Written not in Russian

But everything is easily and clearly drawn

Manufacturer China, but we bought in a store in Moscow. The kit included a USB cable, but it, unfortunately, turned out to be faulty. By and large, it doesn’t matter at all, because you can use quite any charger from your phone or tablet - all connectors are standard. The biggest plus, in my opinion, is its case - it is rubber - waterproof and dustproof, shockproof

And this is very important! As well as the presence of a solar battery.In the photo, you can see that one rectangular light is on - this means that charging from sunlight is in progress.

Quite light, about 100-150 grams. The ribbed surface on the sides, which does not allow slipping out of the hands.

Dimensions: 14.2 cm x 7.5 cm x 1.4 cm. So it will not be convenient to carry in your pocket

But you can hang it on your belt (on a belt) or fasten it to your bag, whichever is more convenient for you. There is a special hole for this.

A little information is also written on the body of the power bank itself. Unfortunately, green on green is not at all visual and hard to read.

Two flashlights. One small - literally one light bulb

And on the reverse side there is a full-fledged flashlight, and from diodes, so the flashlight will definitely never burn out and will not let you down

Flashlights are turned on using the button on the top of the power bank

If you press the button and hold it a little, the flashlight from the diodes will turn on. I test during the day, but at night it is very bright!

It turns off in the same way - press and hold a little. Two presses on the button - turn on a small flashlight.

It turns off the same way it turns on. It shines quite well, it is convenient to illuminate the keyhole if it is dark on the site. Two USB connectors, so you can charge two devices at the same time. And one micro USB to charge the power bank itself

The battery capacity is 8000mAh. It is charged from the solar battery and from a network. We connect:

Now we see that when charging from the network, our lights are on. It didn’t quite turn out to be visible, but in fact it is a power bank battery indicator. One light is always on, as the solar battery is charging, and when plugged into the network, the lights start flashing, and you can determine the degree of charge.As the charging progresses, the bulbs remain lit, thus, when the power bank is fully charged, then all the bulbs will light up - there are only five of them. Now let's put the phone on charge from our miracle charger. We connect:

Yes, it's really charging.

Moreover, when charging the device on the power bank, the bulbs continue to burn. Now there is a reverse process here - we see how much charge remains in it, and how much is transferred to our rechargeable device. But now, as the power bank gives up its energy, its indicator lights go out. So now you can always be in touch, anywhere and in any weather. The purchase was very satisfied. I think it's an excellent choice - you won't regret it! Let's summarize. Pluses: 1. Waterproof and dustproof, shockproof; 2. Solar panels: 5 x 200 mA3. 2 USB ports for charging4. The presence of 2 flashlights5. Can be purchased online Cons: 1. There are no instructions in the kit (although now everything is on the Internet, but I would like to see it); 2

Poor-quality USB cable included. That's all, thanks for your attention and happy shopping!

What exactly does the solar panel provide?

There is hardly a driver who at least once in his life has not encountered the problem of discharging the battery at the most inopportune moment for this. There can be many reasons for this: the audio system worked for a very long time, the car owner forgot to turn off the lights, the vehicle was idle for a long period, etc. It may also happen that you are just lucky if the owner of the car is nearby who will allow you to “light it up”. And some especially savvy citizens even prefer to carry an auxiliary drive with them, just in case, so to speak.

It is in such situations that a solar panel, which is a battery of solar cells, will fit perfectly. This gadget will help you charge the battery in order to be able to start the car. By the way, in the design of many solar systems for residential buildings there are standard car batteries.

If anyone thinks that solar cells can be used as a full-fledged battery charger, they are greatly mistaken. To recharge a completely exhausted drive from newfangled batteries, you will need 9-11 hours - a period, let's say, is not small.

Two simple conclusions follow from this:

• solar panels are designed to maintain the required charge level during the trip;

• in a critical situation, solar panels can replace the so-called "lighting" from another car. They will charge the battery to a level that allows you to start the car and continue driving.

Without a doubt, solar panels integrated into a vehicle are an excellent solution for those car owners who travel long distances and are often far from civilization. In addition, such devices simply need to be tested by those users who actively use multimedia systems in cars. And any other systems with increased power consumption also need additional power sources.

Portable wind generator

Portable Camping Wind Turbine

If you attach a propeller to a dynamo, you get a wind generator. It no longer needs to be twisted manually and it can give much more power, depending on the diameter of the blades.

On a sailing catamaran, which sails for a long time on a constant course, there may still be a place for such a windmill. And on a kayak that maneuvers along the river, you can’t put it.

The advantage of the wind generator is a sufficiently large power, it can work even in rain and at night.

Minus - even a portable device is quite heavy and bulky, requires special conditions for installation, and the wind is not always there.

A few helpful tips

Before purchasing, it is important to understand that it will not be possible to charge a car battery using a solar power source in a short time, even if you have a battery with a power rating of 40 watts. The time during which the battery is fully charged, in this case, the usual

It is the same as when using standard chargers. The minimum charging time is 9 to 11 hours. Most often, solar batteries are purchased precisely for the purpose of recharging the battery of a car on an emergency basis, which is important when traveling long distances.

As already mentioned, a solar system of large size and high power is often installed on the roof of a car. But there are also more compact options that fit, for example, on the dashboard. They are designed to slightly relieve the battery, powering the receiver, TV or other devices in the cabin.

It is important to carefully inspect the product for the reliability of the case before buying. Don't fall for cheap Chinese panels made of flimsy and lightweight plastic that melts easily if exposed to direct sunlight.

Charging the battery from a solar battery is notable for the fact that it does not differ in high current strength. This distinguishes it from standard chargers. The current indicator of the solar panel is a maximum of 2 Amperes, so there is no risk of overcharging the battery. Charging will be slow but reliable and safe, while you can rest easy without worrying about overcharging.

Main characteristics of batteries

In batteries for the solar system, it is necessary to perform reverse chemical processes. Multiple charging and deep discharging is not possible in every battery. The main characteristics of suitable batteries are:

• capacity;
• device type;
• self-discharge;
• energy density;
• temperature regime;
• atmospheric mode.

When buying a battery for a solar system, special attention should be paid to the chemical composition and capacity, be sure to pay attention to the output voltage. You should choose a convenient place for installation and maintenance of the battery

You should choose a convenient place for installation and maintenance of the battery

Premium options for gel batteries are able to painlessly leave the state of full charge discharge, and the cyclic service reaches five years. Due to the dense filling of the electrolyte on the surface of the electrodes, corrosion is excluded. High-quality batteries have low self-discharge and are able to operate under extreme temperature conditions.

Portable devices and delusions

Before proceeding further, it is necessary to give the widespread opinions to which everyone listens. Some of them are incorrect.

1. Crystalline models are a priori better than amorphous devices. This is not true.Often the last, flexible devices work more efficiently. They say they are the future. What matters here is not the type of solar battery, but the quality and parameters of the device.
2. Amorphous models burn out very quickly, and can lose about 10% of productivity in a year. However, the check revealed a drop in efficiency by 4%, but it happened after 14 years of active operation.
3. Flexible solar panels are better, as they are more efficient in cloudy weather. This is also not entirely true. It all depends on the parameters of the device and the reliability of its manufacturer.

Since it is best to focus on the opinions of those who have long and successfully used such solar devices, it is best to list those batteries that have earned high ratings from buyers-owners.

What is important to know when buying a solar panel

Each user will cope with the choice of a network adapter, since there is nothing complicated in this. Difficulties arise only when buying a solar battery. Because there are several nuances that you should know about in advance.

First, it is important to decide what exactly will be charged from this panel. Because today there are dozens of models that are suitable for both a smartphone and a car battery.

After clarifying this issue, you should move on to the next item - how quickly you plan to charge. The last question is in what conditions the device will be used.

These are the main criteria that are given attention in the first place. Of course, we must not forget about the cost of the product and the manufacturer, but this is secondary.

From phones to laptops

If a person plans to use a solar panel to charge smartphones with a capacity of up to 5000 mAh or action cameras, then almost any budget solution will do. These models have one USB port, where up to 1.2 amps are issued. This value is sufficient for undemanding equipment

Additional functions are not provided here, which is also important to understand

If you need to charge more complex devices: tablets, external power sources or smartphones with a capacious battery, it is better to purchase expensive options from popular manufacturers, for example, Blitzwolf 15 Watt. This option has several connectors and operates simultaneously with two devices. In this case, the current indicator can reach 2.1 A and higher.

Such a panel may not be enough if a person plans to charge phones that support Quick Charge technology or portable batteries with a capacity of 20,000 mAh or more. In this case, devices whose power exceeds 18 watts are suitable. One of the popular representatives is Allpowers 21 Watt.

But the solar panel isn't just limited to charging phones and tablets. Models are sold that can work with car batteries, portable refrigerators, laptops, etc. Of course, the cost of such performances reaches a high mark, but in return a person receives a durable device. It will help out in any situation or during long trips. Before choosing a panel, you should take into account the current consumption of the device, and then compare the indicators with the output value of the solar battery.

Charging speed

There is nothing difficult in choosing here.It is better to buy models that give the same result as when using standard charging. Also, do not forget about the maximum current and voltage. For example, when charging a regular smartphone, parameters of 5 volts / 2 amperes are required. Today, these values ​​are used in almost all network adapters. The solar panel should have the same indicators, more or less is impossible, as this will have a bad effect on the battery. In this case, the Allpowers 14 Watt solar panel will be the optimal model.

Operating conditions

The parameter is important to consider if a person plans to use the device on a long trip or a trip to a country house where there are problems with electricity. For these purposes, standard versions are suitable, with a power of 10 to 12 W

This is the best solution that will cope with charging modern smartphones and tablets.

If a person plans to go on a trip for 14 days or a month, it is better to purchase models with a power of 18 watts or more. In addition, you should additionally buy a power bank with a capacity of 15000 mAh. These two components will be quite enough for a comfortable stay.

China or popular manufacturer

Who and where the device is made should also be considered. Since well-known manufacturers distribute a long-term warranty that will help you return or repair the device. Chinese models differ only in low cost. If possible, it is worth knowing in advance which solar cells are used. Elements that are produced in American factories are considered a good option.
