Modern smartphones and tablets are plagued by one very serious problem: every now and then these devices are running out of battery power. This is understandable: the realities are such that a mobile gadget has become an indispensable personal assistant, and it must be turned on 24 hours a day. The problem of low charge, as luck would have it, no, no, and it catches us by surprise far from home.

But there is a way out. There are portable chargers, which in English terminology are called Power Bank. In fact, this gadget is just capacious external battery, which knows how to give its charge to charge the batteries of your devices. For this, it has connectors for connecting cables used for charging. The number of connectors and their variety depends on a particular instance.

A typical power bank is a small brick with one or more batteries inside. Such a device is charged from an electrical outlet, from your computer via USB - in general, in the same way as a regular phone.

For this review, the Xiaomi MI model with a capacity of 10400 mAh was taken as a guinea pig: in the author's opinion, it found a good balance between capabilities and cost.

Appearance

As usual, we begin our acquaintance with packaging. A small white box with a smooth surface on which you can see the security seal with a unique 20-digit code. Due to the increased attention to its products, Xiaomi has protected itself from counterfeiting: if you wish, using the code, you can verify the authenticity of the purchase on the website chaxun.mi.com, the code is located under a protective layer on the brand.

Inside the box is the charger itself, a phone cable and instructions. Alas, in our case, in Chinese.

The body is made of brushed aluminum, the ends are covered with white plastic. To the touch, the material of the case seems to be of high quality, there are no complaints about the assembly, but there are no design refinements either. A sort of austere, non-separable pocket piece of energy, nothing superfluous.

Mi Powerbank weighs about 250 grams. Dimensions - 77 x 90.5 x 21.6 mm. On the case there is a power button, 4 LEDs showing the remaining power supply, and 2 USB connectors. One - standard USB - is designed to charge other devices, and the second - micro-USB - to charge the external battery itself.

Capacity

Xiaomi in its "energy banks" uses good battery cells produced by Samsung or LG. Theoretically, the efficiency of such batteries is 93%, that is, in our case, about 9,500 ampere-hours are available.

In reality, this figure turns out to be even lower and will depend on the energy efficiency of the device being charged.

Experience

The current output of the test sample is 2.1 amperes, which is enough for almost any modern portable equipment. During the operation, statistics were collected, and it was revealed that one charge of the external battery is enough to fully charge the LG Nexus smartphone 4 times 5 or 3.5 times - iPhone 6 or 1.5 times - iPad mini.

There were also some drawbacks. These include the presence of only one USB connector, and if you took several portable devices with you, you will not be able to put them on charge at the same time. Also confusing is the long time to fully charge the external battery: about 12 hours.

Summary

The shortcomings only set off the overall pleasant impression of the device. It is quite suitable for long business trips, field trips or a busy working day. Depending on the store, such an accessory can now be purchased for 1.5-2 thousand rubles.

You can definitely say that such a device will fit everyone, but not necessarily exactly the same. You can also pay attention to inexpensive counterparts under the brands Samsung, Lenovo, iconBIT, Canyon, Golf. There is a choice, and some gadgets may seem to someone even more attractive in terms of their capabilities or design than the hero of this review.

But there are also various gadgets from our daily life - smartphones, tablets and e-books. And all of these devices need power, especially when they are used intensively. Today we will figure out how to ensure the smooth operation of the electronics taken on the hike.

Before building a power plan, carefully study the capabilities and characteristics of your devices:

How many consumer devices will be taken on a hike? The more there are, the more acute will be the issue of providing them with electricity. What kind of batteries do they use - batteries or rechargeable batteries? If batteries are used, then clarify their parameters - can they be recharged via USB ports or they will require a separate charger. It is also equally important to understand how long the battery can work on a single charge, which is determined by its capacity. What is the capacity of the batteries? This information is provided by the device manufacturer. In the case of gadgets and portable devices that use small batteries, the charge capacity is most often indicated in milliampere-hours (indicated by mAh or mAh). The higher the value, the longer the device can work on a single charge, but everything here depends on its "gluttony" and frequency of use. Which brings us to the next question. How intensively will the device be used on a hike and how long will it last? Will you choose a strict battery saving mode, or will you take full advantage of the device's capabilities? How quickly the charge will be consumed in this case is better to be convinced in practice. For example, spend a short weekend hike, where you can "test" your electronics in "combat conditions", and then build a clear power plan.

So, let's consider all the options for charging electronics on hikes. Further in the material:

Ways to charge your devices on hikes:

Portable Batteries

The main "must have". The portable power bank is the most ergonomic, lightweight and compact way to recharge most of your devices on the road. Their modern assortment is huge - you can find extremely compact and lightweight models focused on charging gadgets from USB, as well as for much more power hungry devices - laptops and SLR cameras. There are also universal solutions, for example, the compact Goal Zero Sherpa series batteries are capable of charging the entire range of portable electronics.

"Powerbank" will be useful not only on a hike - it will become a faithful companion on travel and business trips and will be useful to any active city dweller who has ever faced the problem of charging a gadget outside the home.

How to choose a portable battery?

The basic parameter is Battery capacity- the higher it is, the more charge cycles the powerbank can provide to your device or devices. Moreover, its capacity should be even higher than the anticipated needs of your electronics. For example, a powerbank with a capacity of 10,000 mAh will not be able to fully charge a smartphone with a 2,500 mAh battery 4 times, maximum 3 or 3.5 times. The reason lies in the inevitable losses associated with charge controllers . It is important to observe a certain moderation, because the higher the capacity of the "power bank", the more it is. dimensions and weight... So the economical use of an electronic device will not only stretch the time autonomous work but will also lighten the backpack. Do not forget about compatibility purchased "powerbank" with your devices. Make sure it can supply the voltage it needs at the output. Most gadgets will be able to charge from the USB port, which is equipped with almost all portable external batteries produced today, but for more power hungry consumers, laptops or DSLR cameras, you will need a separate outlet with a voltage higher than that of USB. An important selection criterion is credibility of the manufacturer portable battery. Responsible brands not only indicate the maximum exact values ​​for the capacity of their devices , but also equip them with high-quality electronics - charge controller, protection systems against short circuit, overload, overcharge and overdischarge. It should also be borne in mind that the most popular models of portable batteries on the market, for example, from Xiaomi, have many fakes, and you need to carefully choose the seller.

Finally, some vendors such as Powertraveller and Goal Zero create power banks that focused on operation in field conditions... They have durable and sometimes sealed casings, are ergonomic, and - most importantly - can be efficiently charged from non-standard power sources - solar panels and bicycle dynamo hubs. The device "Vampirchik", which is quite well-known in the circles of electronics lovers, is also suitable for outdoor use. This is a domestic "power bank", which is able not only to work correctly from solar panels and dynamo bushings, but also to "issue" the voltage required by the user to charge a wide range of devices. However, for its full operation, a careful study of all instructions, experience, as well as certain knowledge in the field of electrical engineering will be required.

Solar panels

In the wake of interest in environmentally friendly energy sources, samples of portable hydro and wind generators have already been created. However, so far only solar panels have found their place in hiking practice. What do you need to know before buying them?

The big question is, do you really need a portable solar panel? Solar panels are powerful enough to efficiently collect charge during daylight hours and add almost a pound or more to your backpack. To this must be added the weight of the buffer "power bank", and this is an additional 250-350 grams. Therefore, if the trip does not differ in duration and a high degree of autonomy, it is not planned to use a large number of electricity consumers, and their charge is consumed sparingly - the need for a solar panel simply disappears. In this case, it is easier to replace it with a pair of "power banks" and a supply of replaceable batteries - batteries and accumulators.

Keep in mind that the efficiency of the battery is directly dependent on solar activity in the region where the trekking route lies. It, in turn, depends on the geographical location of the area and the time of year. For example, in the Altai mountains or in the Crimea, a solar panel will collect many times more energy than in the Urals or in Karelia. And in winter, the efficiency of its work will be much lower than in the summer months. In addition, to make the most of the solar array, it will need uniform illumination and, if possible, correct orientation relative to the sun. It is far from always possible to comply with all the listed conditions during the hikes.

However, in certain situations, portable solar panels have proven to be highly effective:

Passage of autonomous and semi-autonomous routes lasting more than a week. In such a situation, with the active use of several devices and gadgets at once, the weight of the supply of batteries and "power banks" can significantly exceed the weight of one powerful solar panel, which works with one external battery. These include work in basic mountaineering camps, long cycling and water expeditions, long hiking trails in remote corners of the planet. Providing electricity for camping without using gasoline generators and a car engine. Emergency power supply required to ensure communication and navigation in an emergency situation (for example, when a storage battery breaks down and the devices used are discharged). "Urban" tourism and travel, especially in third world countries, when it is not always possible to charge your gadgets from the network. The need to work remotely, in a place without a stable power supply. For example, keep in touch with the office and answer email while being on a secluded wild beach.

As we have already noted, the lighting conditions that fall to the lot of tourists are often far from ideal. The solar panel is often "on the fly" attached to a backpack or kayak deck, and the light level is constantly changing due to the movement of the sun, weather conditions and the constant change of light and shade. In such a situation, the solar battery most often produces a current that is much weaker than what is stated in the technical documentation. As a result, many devices, mainly smartphones and tablets, simply refuse to charge from such a power source. Therefore, solar panels are most efficient when working in tandem with universal external batteries, which "collect" absolutely all the energy that is produced by solar modules.

Within the framework of such a power scheme, the buffer external battery is gradually charged throughout the daylight hours, and the stored energy is given in the evening and at night to those devices that need it.

On a hike, the solar panel should work as much as possible, collecting all the available energy. In the photo, the Goal Zero Nomad 7 solar panel is attached to the backpack and charges the Goal Zero Venture 30 battery © massdrop.com

Benefits of using an external battery:

The presence of a reserve of energy in case of worsening weather conditions. Increases the safety of gadgets and devices that can be damaged or lost when directly connected to a solar battery (overheated in the sun, got wet, fell, etc.). An external battery allows a tourist to be more mobile in a bivouac, and not to sit in the sun being "tied" by a cable to a solar battery. More efficient storage of solar energy.

In connection with the ingrained practice of using the "solar panel + external battery" bundle, there are three configuration options on the modern portable solar cell market:

The buffer accumulator is built into one housing together with the solar module. As a rule, it has a small capacity, since solar panels of low power are used in such systems. Examples are BioLite Solar Panel 5+, PowerTraveller Solarmonkey Adventurer. The solar battery is immediately completed with a portable external battery "from the manufacturer". Examples are PowerTraveller Solarmonkey Extreme, Goal Zero Venture 30 Pack. The solar battery is sold separately, and the choice of an external battery is up to the buyer. Although the manufacturer recommends certain devices from their catalog. The reason for this is simple - not all "power banks" are able to correctly collect energy from such a complex power source as a solar panel. Therefore, before buying a solar battery or an external battery for it, make sure that this tandem will work. This can be done according to reviews on the Internet or using the recommendations of the manufacturer itself.

How to choose a solar panel?

If you do not go into numerous technical details, then the main parameter when choosing a solar battery for hiking is its power... The higher it is, the more energy the panel collects per unit of time, all other things being equal.

What power solar battery should I prefer? The output power of solar panels, which can be safely called portable, varies in a very wide range - from 0.5 to 75 watts, but in real camping practice, 5-20 watts models are most often used. Panels with an output power of less than 5 watts, as a rule, are built into the cases of external "power banks" and are not able to work effectively in practice, since they charge the equipment extremely slowly even in ideal lighting conditions. Their low power is due to the small area of ​​the photovoltaic panel, which manufacturers tend to fit into a compact body.

Next, you should find the optimal balance between power, weight and size of the battery... Solar panels with a power of 5-7 watts captivate with their compactness and low weight and, working in tandem with a good "power bank", are able to gradually store the necessary energy in clear sunny weather. If the climate is not characterized by stable meteorological conditions, and the weather is often rainy and cloudy, then perhaps more powerful models (9-20 watts) should be preferred. They will be able to recharge the buffer battery relatively quickly in short "windows" of good weather, but they will be much heavier.

Solar panels with a power of more than 12 watts will be needed to charge consumer devices with an operating voltage of 9-12V, which are not capable of being powered by a simple USB output. We are talking about the batteries of laptops and SLR cameras. Some solar panels with a capacity of 20 watts or more are even capable of "reviving" lead-acid car batteries in the event of an emergency, or powering a portable camping refrigerator that runs on a cigarette lighter.

Spare batteries

In some situations, it is problematic to charge batteries without using special chargers. These can be batteries from a GPS navigator, camera or walkie-talkies. In such a situation, the weight of the "charger + powerbank + solar battery" set may turn out to be prohibitively high and, accordingly, simply stock up on replaceable charged batteries.

Exotic methods of recharging devices

Here we include boilers and burners equipped with converters of thermal energy into electrical energy, portable water and wind generators. Alas, so far these devices can hardly provide the necessary electricity for travelers and replace compact "power banks". But, as time goes on and similar technologies are becoming more effective. Perhaps in the future we will really be able to quickly charge our phone or navigator simply by making ourselves dinner on the burner.

Now let's consider the most optimal ways to recharge on examples of specific electronic devices that are often used in hikes.

How can I charge my phone, camera, navigator and other devices while hiking?

Cell Phones and MP3 Players

A simple charge push-button telephone most often enough for the entire route. Unless, of course, you call your mom every half hour. If, even in the conditions of a hike, you have to literally "sit on the phone", then an external battery of a small capacity will be enough to recharge it. The main thing is to have the appropriate cable with you. MP3 players also do not differ in gluttony, so you can safely use the same battery to charge them.

Smartphones and tablets

The versatility of these devices, combined with their relatively low weight and compact dimensions, allowed them to fit into the backpacks of many tourists. A modern smartphone provides not only Internet access and telephone connection, but also has a good camera for amateur shots and is often equipped with a GPS module, which is useful when navigating a route. But with intensive use, even the most durable models cannot last more than 2 days on a single charge.

As you know, modern mobile devices and gadgets need to be constantly "fed", that is, energized. Gadgets allow us to always stay in touch, but at the same time they have the unpleasant property of being discharged at the most inopportune moment. A person may need electricity for resuscitation mobile phone when traveling or to recharge your laptop in an urban setting when suddenly a power failure occurs.

It must be said that there are already plenty of ways to obtain electrical energy in applied physics, and even in everyday life. One of the most famous and affordable ways is to simply build a windmill with propeller blades that will rotate by the force of the wind. And supply it with a generator pulled from the car to convert mechanical energy into electrical energy.

However, some craftsmen go much further and "get" electricity from products that have certain electrolytic properties. For example, from the most ordinary potatoes. In order to get electricity from the tubers of ordinary potatoes, it is enough to have salt, toothpaste, a skein of wire and, in fact, a potato. The potato is cut in half with a knife. Wires are drawn through one half of the potato, and a small depression is made in the other. This cavity is filled with a mixture of toothpaste and salt. Next, the two halves of the potato are connected to each other. Pre-stripped wires are finished with paste. Such a simple device is something other than a small generator of electricity. Israeli scientists have already learned how to create batteries based on real mashed potatoes from five to six boiled potatoes. Moreover, the light produced from such potato batteries, as their creators assure, is several times cheaper than using a conventional kerosene lamp.

But electricity from potatoes is still a somewhat exotic way to obtain energy. In the modern world, there are many more interesting and less laborious options for obtaining electricity to recharge your mobile device. Many have already been created various devices for recharging gadgets, as they say, "on the fly". We will talk about some of them in more detail.

Of course, the first thing that comes to mind when it comes to using alternative energy to recharge various gadgets is the energy of the sun. Indeed, in developed countries, many panels are already successfully operating that convert the sun's energy into electrical energy. Why not use solar energy to quickly charge your smartphone or tablet? In this regard, the Carbon device, presented on the Kickstarter site, looks very interesting. Outwardly, it looks like a bracelet or a wristwatch that you can always carry with you. A solar panel is located inside the device. This allows the Carbon bracelet to charge slowly throughout a sunny day, such as spending time on the beach or on a hike. In the evening, you can use the energy accumulated by the device to recharge your mobile phone.

The capacity of the battery built into the bracelet is 650 mAh. Thus, the full capacity will be enough to power a smartphone or other mobile device for up to three hours of talk time and web surfing. This, you see, is very good if you are outside of access to the power grid for a long time. The device can easily connect to popular devices based on iOS or Android, recharging them on the fly. Carbon is available in a waterproof case with a leather strap. Interestingly, this useful device can also be recharged from a standard USB, so you can pre-charge it at home when going on a trip. Also Carbon is equipped with a flashlight and strobe to signal help in an emergency.

Those users who need something more powerful to recharge mobile devices while traveling, can turn their attention to the Sun Socket Solar Generator solar station. Portable station - the ability to get electricity in nature, far from cities. Such a device can be used while hiking, as well as in emergencies. When folded, the Solar Generator resembles a briefcase with documents. The station consists of a system of sliding panels, coupled with a built-in battery, in which energy is collected. When the panels are pulled out, they are 114 cm long, which ensures high efficiency in collecting solar energy. In addition, a special mechanism automatically rotates the monocrystalline panels so that they always absorb the greatest amount of rays.

The Sun Socket Solar Generator uses a lithium iron phosphate battery that can hold a charge for a long time... Suffice it to say that the losses per month are no more than two percent of the full charge. Conventional lithium-ion batteries cannot boast of these characteristics. The Solar Generator can be recharged not only from the sun, but also from a regular power grid. In any case, it will take about five hours to fully charge the station, and twice as long when recharging from the sun in cloudy weather. The device is equipped with a universal socket, a 12-volt socket and four USB connectors.

With a portable generator while traveling, you can charge not only mobile phones and tablets, but also televisions or satellite communications. Sun Socket Solar Generator allows you to almost completely satisfy human needs for electricity far from civilization. The neat case weighing just over eleven kilograms is quite convenient to carry with you. Such a device is especially suitable for providing power to a tourist camping. The development of Aspect Solar has already attracted the interest of many travelers, although the cost of such a portable generator is quite high - about $ 1,500.

Wagan solarEPower Case 450

Another useful device that uses the energy of the sun is the Wagan Solar E Power Case 450 autonomous charger. This device also looks like a suitcase, but it can hardly be called a compact solution. The dimensions are more solid, and the weight is about twenty kilograms. However, the Wagan Solar E Power Case 450 compensates for its size with power. Inside the device, as expected, solar panels are located, ready to collect energy. These are two 20W batteries.

In general, this device is designed to simultaneously charge several mobile gadgets at once. Therefore, it is equipped with multiple USB ports, a 12-volt socket, two universal outlets. A voltmeter is provided for assessing the charge level. The case has a sturdy handle and strap for easy portability. You can safely throw it into your car and use it if necessary while traveling.

In addition to solar energy, there are other, perhaps much more interesting, ways to generate electricity for quick recharging of various devices. In particular, the problem with charging the phone in nature or on a trip can be solved by the FlameStower hiking gadget, which works on the thermoelectric effect. FlameStower is capable of generating energy from a conventional campfire that can be made in field conditions. Of course, it is difficult to accumulate a lot of energy in this way. Flame Stower generates only about 2 - 3 watts. But this is quite enough to provide two or three minutes of talk time for a mobile phone in a minute. It is noteworthy that the device can be recharged both from a fire flame and from a gas stove.

You only need a little water to use the device. It is poured into a tank, after which it is heated by fire. Due to the temperature difference, electricity is generated. In this case, the charging speed directly depends on the heating temperature. That is, the brighter the flame, the more power is obtained. FlameStower can be useful not only for charging mobile gadgets while traveling, but also for home use in conditions of network outages. The device has a fairly modest size and weight (no more than two hundred grams). Plus, it folds into a compact plate making the FlameStower easy to take with you on any trip. Mobile devices can be connected to this device for quick recharging via the USB port.

Eton Boost Turbine

A more original way of generating electricity is offered by the Boost Turbine device. It is a portable battery with manual charging. It can be used in the absence of bright sunlight or fire - only the energy of your muscles is used to generate electricity. Eton Corporation has launched the Boost Turbine 1000 and Boost Turbine 2000 portable devices, which differ in battery capacity (1000 and 2000 mAh). The devices are based on the action of a mini-turbine. The user rotates a special knob for one minute and gets the opportunity to charge his phone with enough energy to make a short call or send text messages... The Boost Turbine 2000 provides a full charge for most modern mobile devices, while the Boost Turbine 1000 guarantees a 40-50 percent charge.

The advantage of Boost Turbine is that the user does not depend on anything - neither on the weather, nor on the time of day, nor on the distance to the nearest settlement. You can easily recharge your phone anywhere and anytime. In addition, this unusual external battery with a built-in dynamo is also a good simulator. After all, the handle has decent resistance when rotating. Moreover, it is advisable to rotate it fast enough to ensure the optimal effect. In this case, you have to make even more tangible efforts. By turning the handle at a fast pace for a few minutes, you can feel how your forearm is being used. At the same time, the device converts your muscular efforts into electricity. The process of rotating the handle is quite energy-consuming, so an ordinary person is enough for five to ten minutes of rotation with one hand.

Of course, the Boost Turbine can hardly be considered a permanent generator of electrical energy. It is more of an emergency travel option. If a person during a hike got into a situation when all mobile devices were completely discharged, the external battery also went to zero, there is no power grid nearby, but it is very important to make a single call or send a message, then BoostTurbine will come to the rescue. Twisting the knob a little and then connecting the battery to the phone, you can make an urgent call. By the way, at the end of last year, Eton Corporation presented more powerful model manual charger BoostTurbine 4000, capable of recharging most modern mobile gadgets twice due to the increased capacity of the lithium-ion battery.
