You quickly get used to good things, and therefore it is not surprising that the modern generation can no longer imagine itself without tablets, mobile phones and other modern gadgets, especially without a solar-powered Power Bank - an external battery that will help recharge them at any time, so as not to remain without contact.
Description
For everyone who practically never parts with mobile gadgets, this is an extremely useful thing. This solar-powered design reliably stores accumulated energy until the moment it is needed.
It is clear that solar Power Banks Solar, produced by many manufacturers, differ in characteristics and prices, which directly depend on the quality of the energy-saving elements.
It is important that the self-charging device can be replenished with energy not only from sunlight, but also from a regular household network. LED indicators indicate the remaining charge.

Choice
When going shopping, it is important to remember the main criteria that must be taken into account when choosing:
- maximum accumulated energy (written on the body of the power bank);
Important: Very often the manufacturer overestimates this indicator for no apparent reason: either for advertising purposes, or based on other indicators. Therefore, it is necessary to make allowances for this and understand that in reality this value will be 80 percent of the indicated value.
- manufacturer. Chargers made in China will please you with their price, but you can expect all sorts of surprises from them.
- price. Models are available in budget versions and more expensive ones, so this is important to consider when choosing a goal. To recharge a mobile phone, for example, at a party, it is enough to purchase a small-capacity model, which is inexpensive. To maintain the functionality of the tablet or use it on a long trip, it is advisable to choose a more serious model.
Minuses
- A solar power bank is essentially the same battery, but uses solar radiation. The disadvantage lies in the fact that if it was not possible to charge the battery during daylight hours, when darkness falls, nothing will shine, literally or figuratively;
- Next is the capacity. It is so small that there is no way to charge powerful devices. On the one hand, it’s good when the external charger has a flashlight, but you need to take into account that it will take some of the energy;
- Non-replaceable battery - the lithium-ion battery is no different from those that are equipped with mobile phones, but if it fails, it is impossible to replace it;
- Solar Power Bank models with a solar battery are inexpensive and have 18650 cells that can be installed and replaced without problems;
- The advantage of the former is the rapid release of accumulated energy and its long-term storage, i.e. they cannot discharge spontaneously;
- Despite the existing shortcomings, for those who like to travel and go on hikes, such chargers are a godsend. Even in a highly discharged state, they will allow you to send an SOS signal.

If you order from China, it’s not that expensive. It is now probably more difficult to find a Chinese power bank without a solar battery than with one, but of course there is no charging from it.
Vasya
Nastya, why not? For example, I charged 3% in one daylight! :)) I kept it in the sun specifically to check how the charge was going.
Krak
Vasya, 3% per day is not even bad! How did you measure the degree of charge? If 3% per daylight hours, then in a month you can charge 100%, but the article says that 260 DAYS is needed.
Vasya
Krak, I measured it with a Fluke multimeter, but I made a mistake when I wrote))) not 3%, but 0.3% per day. So everything agrees with the article. Photocells on the body are needed for beauty, but not for charging. For me, it would be better if they drew some kind of Pokemon - it would be more useful.
Gleb
Vasya, what's the matter? Cover the panel with a Pokemon sticker!)

“Weight of the case, microcircuit and additional parts inside” - did you weigh it yourself? From 50 to 70 grams, well, certainly not 200)
Victor Osipov
Guys! They take us for suckers - 50,000 mAh = 50Ah, this car can be started by capacitor starting!
Victor Osipov
I forgot to add the test result of a Chinese Power Bank with a capacity of 10,000 mAh - it came to me with three out of four glowing charge/discharge indicators! I immediately turned on two smartphones with 70% charge - they charged in an hour and an hour and a half! I was discharged by one strip! I lay on the windowsill for three days - zero emotions! Well, scribe, I’m thinking, how can I charge you? And then he finished - the data cable that came with it was connected to the computer! I charged the card in total, I tried it with a phone charger, it seemed faster! I don’t know how long it will last, but for that kind of money a good thing came from China! I’ll add on my own that buying a larger capacity is not wise, I think. Maybe there is a reason for tablets, but for smartphones it’s just right (enough for a couple of charges).
Alexei
you are not “most likely” being deceived, but definitely and one hundred percent. in such banks the largest will be 7000 mAh. it's in the most bulky ones. in those that are simpler 5500, and in thin ones even 3500. By the way, on mine the power of the socket is honestly indicated - 0.2 W, which is 5V = 40mA, and the microcircuit blinks four merrily! indicators)))
Nikolai
I have a 50,000 mAh bank. Discharged to the limit, charged with 1 ampere charge in 24 hours, i.e. actual capacity no more than 24,000 mAh, device weight 287 grams
Alexander
I bought a Power Bank 20000 mAh solar, completely discharged it and charged it from a 5V 1A current source. It was charged for about a day while monitoring the parameters with a digital tester. The resulting capacity is 5646 mAh, i.e. almost four times less than promised. There is almost no use for a solar battery, unless you keep it on the windowsill to eliminate the self-discharge of the batteries. I've seen power banks on the Internet that already have 100,000 mAh, i.e. 100Ah. Of course, this is just advertising aimed at people who are far from technology. A 5Ah capacity is enough to charge a phone three times or use it as an additional 5V 5Ah power source.

And soon there will be chargers - windmills, you run and charge)))

The M300-01200017A frequency converter differs from the CIMR-F7A42P21 frequency converter in the rated power of the IF, the operating frequency of the PWM controller, the logic of the system for automatically diagnosing errors in the frequency converter, and also to a greater extent in the presence of various internal additional functions that are available for easy setup and performance of specialized tasks and completely replace constitutes instrumentation and automation for automatic operation of external industrial equipment without the use of additional external elements such as controllers, operator panels, industrial computers. These factors play a decisive role in selecting a frequency converter for various applications.
Checking faults and subsequent competent repairs on new equipment of frequency converters, which are manufactured by danfos, delta, vesper and other global brands. Production of replacement IGBT semiconductors, which are very fundamental components in the entire device of converter technology. The difference between an IGBT transistor and an IGBT module is that the module may contain one or more IGBT transistors, sometimes connected in parallel using a Sziklai pair circuit to increase the switching power, as well as in some cases a load current control circuit. IGBT, an insulated gate bipolar transistor, is a power semiconductor device commonly used as an electronic switch for medium and high voltages. By combining the advantages of a bipolar transistor and a field-effect transistor, high switching power and low required control power are achieved, since control is carried out not by current, but by voltage, which leads to high efficiency of these components.

I bought a 25,000mAh solar via the Internet and sent it by mail. Delivered in 9 days. I charged it for 24 hours, although it says 6-8 hours, and it didn’t charge. I called there and the sender was not available. And when I was charging, the 2nd and 3rd lights blinked. But 1 and 4 didn’t blink. within 24 hours. What should I do? I’m disappointed with these online stores. I paid a lot of money for me. Tell me, who knows. All I have to do is call Rospotrebnadzor where they probably sent it from.
Vadim
Guys, I bought a portable battery for 36~euros or 2,556 rubles. I checked the reality of the volume and oooh miracle it gave me ~29,000. I’m happy with everything and recommend it to everyone.
Irina
What solar chargers do you recommend? Going on a hike. I've seen some that can be attached to a backpack. Like EnerPlex Kickr can bend and is indestructible.
Ivan Vasiliev
Interesting gadget. But I like it better - CGPower Wireless Power Bank.
Andrey
Well, it's probably not that bad. I looked on eBay and Amazon for batteries with solar charging and this is what I found. The most popular and purchased ones have a capacity of 10,000 mAh. Further, cheap ones from China for $8...10 are not quoted. And they are bought mainly for $24...34, produced (the most interesting) in the USA. I took a closer look at this one with the BLAVOR brand. So it and similar 10000mAh capacities are categorically not sent to the Russian Federation. Even if you try to buy from other trading platforms, they categorically won’t send it because it’s high-tech. Their descriptions clearly indicate that the main charging of the device is from the mains. And solar is for emergey - extreme cases.
Alex
It really hurts when such STUPID people pretend to be experts.....
Konstantin
“...260 days. And the sun, as you know, does not shine around the clock. Therefore, the battery will never be charged." what do you mean fucking NEVER, in 260 days the sun will go out and the end of the world will come? What kind of nonsense is written in the article?
Svetlana
Um.. The author says that everything is aimed at people who are illiterate in this matter, and then he talks for a long time about the power of solar panels in mAh and presents calculations... So - the CAPACITY of the battery is measured in mAh, and not the power... hence all the stupidity calculations... It is absolutely clear and obvious that a solar battery takes longer to charge a battery than an electrical network, but the author is a person who is not at all literate in this matter and needs to repeat his high school physics course - the formula for calculating the charging time, knowing the CAPACITY of the battery and the POWER of the battery there.

Power Bank 20000 mAh Reviews of the gadget
Power Bank 20000 mah on solar batteries is a new word in the field of modern technology. The device is designed to recharge mobile devices and other gadgets.
The portable battery does not require power consumption from the network, as it can be charged by absorbing sunlight during the daytime.
Real customer reviews, as well as technical tests, will help you figure out how efficient an external energy storage device is.
General overview of Power Bank
The solar charger Power Bank is a rectangular-shaped portable battery that has several connectors for connecting external gadgets.
The battery comes with an adapter for mobile devices. An additional feature is the built-in LED flashlight.
The main advantage of the battery is its ability to be charged from the sun, the network, a computer and a car battery.
The power supply contains a film battery with high energy efficiency. Its efficiency is 90%. It charges the internal high-capacity battery. The solar panel occupies almost the entire front side of the case.
It is recessed into the box and securely connected to an ultra-thin lithium polymer battery. Such batteries do not overheat and therefore cannot cause melting, as often happens with lithium batteries.
A high-quality board and controllers eliminate device malfunctions.
The lithium polymer battery is not equipped with a memory effect, i.e. if the charging mode is violated (for example, when the battery is not completely discharged), it does not experience a reversible loss of capacity.
The built-in chip warns of impending discharge, protects against voltage surges and short circuits if the device is charged from the network. It is displayed on the front panel of the autonomous power supply system, which allows you to keep the charge level under control.
What devices is the battery intended for?
Thanks to its high capacity, a power bank with a 20,000 mah solar battery can be used not only to charge mobile devices. The external energy storage device can fully charge the following devices:
- e-books;
- tablets;
- game consoles;
- netbooks and laptops;
- video equipment.
Solar Power Bank is capable of simultaneously charging several mobile devices. A fully charged portable battery can provide 10 recharges to external gadgets at a time.
Analogues of solar energy storage
Power Bank today has many analogues, which differ in capacity, design, additional functions, practicality and cost.
A worthy analogue of a solar-powered Power Bank is the Solar Laptop Charger 11200 mAh model. It has many adapters with different voltages and is suitable for charging both mobile phones and laptops.
The main disadvantages of the battery are:
- high cost (about 7 thousand rubles);
- insufficiently high capacity (11200 mAh).
The next external drive iconBIT FTB23000S is made of impact-resistant plastic and has a large capacity (23000 mAh). But the most important disadvantage of the model is its heavy weight, amounting to 650 grams. Such a battery cannot be placed in a pocket.
Solarmonkey Adventurer is multifunctional, has a good design, but the cost of the battery is clearly overpriced (about 9 thousand rubles), which makes it inaccessible to a wide range of buyers.
KS-IS KS-202 is a cheap Chinese analogue, the advantages of which culminate in its cost (about 1 thousand rubles) and light weight (164 grams).
The body of the device is made of plastic, which makes it quite vulnerable to use. The battery capacity is only 5000 mAh, which may not be enough to fully charge modern gadgets.
In addition, the external drive does not have a second USB port.
Main advantages over analogues
A solar-powered power bank has a number of advantages over its analogues, among which the following should be highlighted:
- large battery capacity;
- stylish design;
- shockproof housing;
- low cost;
- light weight;
- compact dimensions;
- environmental Safety;
- ability to charge two devices simultaneously;
- multifunctionality.
In addition to the above advantages, the external energy storage device boasts operating temperatures that range from minus 20 to plus 40 degrees Celsius. The power source can operate in any weather and has a high level of protection against moisture penetration. While hiking, the device can be fastened to a backpack or belt with a carabiner so that it can be recharged while moving.
Besides everything, the weight is just over 200 grams. and dimensions of 12/7.5/2.2 cm make the device quite convenient to carry in your pocket.
Today, a solar-powered Powerbank costs 1,990 rubles, which is significantly lower than the cost offered by competitors. You can buy analogues at an identical price, but they are inferior in many respects in functionality, external characteristics or have a lower capacity.
This is interesting: Using solar panels for heating a private home
Buying a solar-powered Power Bank means becoming independent from portable devices, which are passive devices and, after recharging the phone several times, turn into a useless load.
Tests performed
During the tests, it was found that the solar-powered Power Bank 20000 is capable of fully charging a mobile device in just 2 hours. It took twice as long to fully charge larger devices such as a laptop.
When connecting a device (with a power of at least 9 Watts) to a 2.1 Ampere port, the charging process was twice as fast as when connected to a 1A input.
The battery capacity allowed us to fully charge the iPhone – 8 times, Samsung Galaxy – 7 times.
User manual
Before putting the Power Bank with a solar panel into operation, it is necessary to discharge the external battery, after which it must be fully charged from the network, which is due to its large capacity.
The fact that it is time to turn off the drive will be indicated by 4 indicator lights, which should all light up. The charge level is shown by indicators as a percentage. So, if one light is on, it means that charging is at 25%.
When charging from the mains, the body of the Power Bank may heat up, but after full charging it cools down to room temperature on its own.
In the future, the gadget can be recharged for quite a long time using solar energy, and it is not necessary to turn on the device, this process occurs automatically.
The solar-powered Powerbank itself can be fully charged from the mains in 1 hour. During the daytime, the battery is charged from solar energy in just 7-8 hours. You can increase charging efficiency by placing the device in direct sunlight.
Customers' opinions
Reviews about solar-powered Power Bank can often be found on various forums. The problem of nutrition is relevant today, since almost every person has two or even three mobile gadgets.
There are thousands of models on the market, among which it is easy to get confused.
But those users who made the right choice and ordered a Power Bank from the official manufacturer appreciated its capabilities.
Dasha (Kaluga):
“I’ve been interested in orienteering for a long time, so I have a lot of all kinds of electronics. There was also a power bank on the fingers, as we say, i.e. on batteries. But in the penultimate competition, when I had to survive 24 hours in the forest, he seriously let me down, as he refused to charge the navigator.
I seriously approached the issue of buying a new one, and knowledgeable people advised me to order a Power Bank with solar panels 20,000 mah. I tested the device in several parameters: capacity and current. The sports watch was fully charged in 1.5 hours through a connector with a current supply of 1A, the navigator through the second port - in 3 hours.
On my last kayaking trip, the power bank fully met all my expectations.”
Alexander (Volgograd):
“I am an avid fisherman. Whenever possible, I try to fish in remote places, so to speak, further away from civilization and competitors. Therefore, I simply cannot live without a portable battery.
My friend advised me to buy a solar Power Bank; he listed a lot of advantages in its favor. I have been using a power bank with a solar battery for quite some time.
It has already gone through 300 charge and discharge cycles and has never failed.”
Evgenia (Moscow):
“It takes me about two hours to get to work. I spend this time, as well as the rest of the way back, reading an e-reader.
And if before the book’s charge was only enough for me to get to work and then I charged it from the network, then with the purchase of a solar external battery I completely forgot about this problem.
The device is so compact that it easily fits not only in a bag, but also in a pocket. Another plus is the low cost, although I didn’t try to save money. Now I have a great idea for a gift for my friend.”
Svetlana (Izhevsk):
“My husband and I agreed that we needed an external battery for frequent trips out of town. My husband chose a model on the official website, asking me to place an order. But I decided to save money and order exactly the same one, but almost three times cheaper on Aliexpress.
The parcel took a month, for which I already listened to my husband’s dissatisfaction, he said that the manufacturer delivers within two weeks. Having read the instructions, now I’m actually surprised that it was there; it took a day to charge the battery from the network.
All the indicators were on, but the case became very hot and smelled unpleasantly of plastic. The most interesting thing was ahead, when I connected the phone to recharge, it charged, but the battery was completely discharged.
The indignation knew no bounds, especially for the husband, when he learned that this was not an original model, but a Chinese handicraft.”
Negative reviews and comments on forums that this is a scam are received by devices that are supplied to the market mainly by Asian suppliers. If manufacturers who are responsible for the quality of their products indicate the actual battery capacity, i.e.
the buyer knows how much volume he will give to the device being charged, then Chinese markings rarely correspond to reality. In fact, a device whose body says 20,000mAh can supply no more than 2,000mAh. That’s why it’s so important to buy a solar Power Bank from a manufacturer that uses high-quality materials, and not elements that have exhausted their service life.
Chinese manufacturers often make devices from such components in order to reduce costs.

A comment
I bought it through Russian Post from St. Petersburg.
pros
LED panel
pros
Yes, the flashlight works. The solar part also seems to be working (the charge light is blinking), I did not measure the speed
Minuses
The charge is extremely slow, it took more than 2 hours to charge from 43% to 68% (3450mAh phone). There is a suspicion that it contains no more than 5000mAh and not the declared 20,000

TOP 1: Coosen Power Bank 20000 mAh Solar
Review
The first place in the TOP-8 was taken by a model with a solar battery with a capacity of 10,000 mAh, which is relevant for people who actively use mobile devices. Their charger will activate, releasing the accumulated solar energy or electricity to a regular household network.
For those who do not want to waste precious minutes lying on the couch, but try to learn more while going on long journeys, a high-tech, lightweight and compact device will help out more than once.
Modern electronics have quite a large reserve of their own energy, however, it is discharged at the most inopportune moments. This is where an external battery comes in handy, which will quickly return them to working condition.
No wonder they have gained such wide popularity. With them, you don’t need to frantically search for an outlet to replenish energy on an almost extinguished screen.
pros
The model under consideration compares favorably with its analogues in the following advantages:
- small in size, allowing the gadget to be carried in a handbag or pocket;
- attractive modern design, which is understandable: to recharge an expensive phone it is absurd to use a bulky device. But with an elegant new product, harmony is not disturbed;
- multivariate, i.e. the ability to charge from the sun and 220 V network;
- LED flashlight;
- significant battery capacity. You can charge your gadget several times using this device.
With an autonomous charger, you can stay longer at a party or go overnight into nature without fear of remaining isolated. Absolutely all models of gadgets (even two at the same time) can be powered by a solar-powered Powerbank.
Characteristics
They are no less interesting:
- energy capacity – 20000 mAh;
- battery type – lithium, designed for 600 full charging cycles;
- connectors – micro USB and regular USB (two);
- dimensions – 125x22x75 mm;
- weight – 250 g;
- output voltage – 5V;
- flashlight and adapters – yes;
- temperature range – minus 20-plus 40.
Preparing for work
Before turning on for the first time, the battery must be completely discharged, and then charged to 100%. When the 4 LEDs on the panel light up, this will mean that the battery is ready for use.
The model is compact and very convenient. On the opposite side of the solar battery there is a powerful LED flashlight, the other is located at the end, next to the USB connectors and the battery full energy indicator.
To activate the large flashlight, you need to hold the button at the end; to light up the small one, press it twice. When you press it three times, the flashlight starts working in strobe mode, and when you press it a fourth time, the big one turns off.
In addition to solar radiation, a gadget with a solar panel can use artificial light and daylight for charging.

POWER BANK 20000 mAh and 5000 mAh on solar batteries
External batteries PowerBank 20000 mAh and 5000 mAh on solar batteries with photocells are one of the latest developments that allows you to charge various technical devices using solar heat energy.
This is interesting: Causes and consequences of battery overcharging
What is an External PowerBank?
The external storage battery PowerBank is a compact design of low weight and size, having a built-in panel made of polycrystalline silicon with the ability to charge devices with a potential of 7-15000 mAh. The storage part is a lithium-ion battery made of polymers, reminiscent of designs used in mobile communications devices.
The use of lithium-ion batteries is characterized by their ability to quickly store energy. However, along with this, their technical characteristics, such as working capacity, may be outside the values declared by the manufacturer.
This is compensated by ensuring rational distribution of the energy accumulated by the external battery through the use of a microcontroller in the design. With its help, the external charger automatically turns off when there is no payload.
Technical characteristics of powerbank - applications and reality
The main technical indicators of the external battery PowerBank 20000 mAh on solar batteries are:
- capacity parameter potentially possible for accumulation;
- the time required to fully charge the battery.
Regarding the first battery parameter, it should be noted that the capacity of the external battery declared by the manufacturer may differ slightly from what is obtained in practice. This indicator depends on the manufacturer of the product, the materials it uses and the features inherent in lithium-ion batteries.
According to experts and according to the experience of practical application of these designs, the limits of deviation of the actual capacity from the declared one do not exceed 20-30%. That is, by purchasing this device you can count on a reserve capacity of 12000-16000 mAh.
These capacitance values allow:
- fully charge 4-5 mobile communication devices;
- charge a discharged tablet or camera;
- keep your laptop running for several hours;
- ensure the operation of a powerful flashlight built into the design for 6-7 hours of darkness.
Opinions also differ regarding the time it takes for an external storage battery to receive a full charge. This is explained by the difference in the level of solar activity in different places where the device is used, and the presence of residual charge in it.
With the time stated by the manufacturer of 24 hours required for the battery to receive a full charge due to the conversion of thermal energy from the Sun, the actual figures are 2-4 days. Despite this, the charge accumulated by it in most cases is sufficient to ensure the functioning of technical devices necessary for the consumer.
Equipment POWER BANK 20000 mAh with solar batteries
The standard configuration of a solar-powered Power Bank implies the presence of:
- battery;
- a set of cords with a wide selection of USB adapter types for charging compatible devices;
- carabiner for mounting the device on clothing or a backpack;
- original packaging.
The design is an external element for storing energy with a built-in 20,000 mAh battery, and a resource of 400-600 charge-discharge cycles, which is about 10 years of use.
It consists of a black body, made of a combination of stainless steel and plastic with dimensions of 120mmx75mmx22mm, into which a lithium battery is mounted with a solar energy conversion coefficient of 0.95.
The case has two USB outputs with characteristics of 5V 1A, 5V 2A, which allows you to simultaneously charge several discharged devices and a micro USB output that allows you to recharge the battery from the electrical network.
The design is distinguished by the fact that it has a shock-resistant and moisture-resistant body, which allows the device to be used for charging in any climatic conditions outside the city.
However, the battery capacity is lower than that of the previous type of battery and is 5000 mAh.
Moisture resistance is ensured by hermetically sealed rubber insulation, which ensures that the charger can be charged even in rainy weather conditions.
Comparative analysis of POWER BANK 20000 mAh and POWER BANK 5000 mAh
The advantages of POWER BANK 20000 mAh over POWER BANK 5000 mAh are:
- Providing a greater number of charge-discharge cycles during the service life;
- Greater capacity of an external battery with almost comparable dimensions and weight of structures.
Advantages of POWER BANK 5000 mAh over POWER BANK 20000 mAh:
- Shock-resistant and moisture-resistant characteristics, despite the lower capacity of the battery, allow emergency charging in case of force majeure, in the event of a thunderstorm, rain, or accidents.
- The parameters of the POWER BANK 5000 mAh allow the design to be widely used without the risk of damage and with a guarantee of operation in hiking conditions, outside the city, on the road.
Advantages of solar-powered Power Bank over analogues
- An external solar powered Power Bank has the following advantages over its analogues:
- Possibility of receiving charge from two sources: solar energy and the electrical network.
- Functioning in any weather and climatic conditions, due to the shock-resistant and moisture-resistant characteristics of the case.
- The device provides the highest degree of protection IP 68, which means protecting it from short circuits, receiving excess charge, preventing and smoothing voltage surges when charging from the network, thanks to the use of an OVP circuit.
- Ability to charge a wide range of devices with USB outputs.
- The heat resistance of the housing allows the device to operate in a temperature range of -20…+40ºС.
- Convenience of assessing the level of remaining charge using the indicator located on the front side of the case.
- The presence of a powerful flashlight with 20 LED lamps and three operating modes (high brightness mode, medium brightness mode, SOS).

A good quality power bank was delivered to me within a week. The device quickly charges the camera, which eliminates its discharge at an unnecessary moment. An additional advantage of the design is protection from moisture.
Yulia, Murmansk
I ordered a charger, which was delivered to me in 5 days. In general, I was pleased with the quality, but charging from solar energy is slower than from the electrical network. It is worth noting the exceptional quality of the flashlight.
Artem, Krasnoyarsk
I was pleased with the purchase, for such quality the price is very low. I took it without hesitation, because I really needed a device that would allow me to stay in touch while outside the city, in nature, or on the road.
Sergey, Yeysk
A very necessary thing when traveling. With its light weight, it is possible to mount it on the surface of a backpack, which I used and this later helped out my friends by helping to charge their phones. I recommend to all.
Vadim, Krasnoyarsk
I bought it as a gift for my father, who is interested in tourism. Now he will always be able to stay in touch with us.
