We all are familiar with the sudden frustration when the battery icon on the screen suddenly turns into red color from green, be it a tablet, smartphone, laptop or any other devices. It means the battery is going to run flat. As much as we would love our gadgets going on endlessly, that is parts not possible. These devices run on battery, which needs juicing up on a regular basis, and the work is done through battery chargers.
But what if you don’t have access to any power point at that moment, but you need to get going? Perhaps you’re in a park, camping far away from the locality, or walking on a beach? In these cases, the best solar chargers with quick charging capability will come handy.
Why Solar Charger?
As the name suggests, solar chargers produce electrical energy from the sun and provide necessary powers to your device by recharging it. Even though we do not run by the above situations every day, solar chargers can still be a perfect thing for our energy needs.
‘Go Green’ is becoming the most chanted mantra of this century and progressively more people are embracing it. Let me give you a fun fact, the energy gets from the sun every moment is 35000 times more than we use as electricity. An estimate says the sun can go for 4.5 billion years more, and it is a free source of energy, which is more the reason to go solar.
Once you break even with the price of solar charger or panels, they become a freebie, and a medium to harness that huge power from the sun. On top of that, they provide you flexibility if you’re an on the go type person. Solar chargers provide you off-grid power solution, and they come in different sizes, shapes and power capacity for your convenience.
How Solar Charger Works
Imagine the scenario, you are driving through a road, far away from your home. Suddenly your phone battery signals that it’s going to die. You look for a suitable place. Fortunately, you find a meadow, full of bright sunshine falling upon those green grasses. You park your car, take your solar charger and put it on the grass. You connect the USB cable to your smartphone, wait for the charging signal. You can sit back and relax, enjoy the nature, probably read a book in the meantime.
Fascinating and liberating, right? None of the charging part was possible even a decade ago. History of solar panels, or harnessing solar energy goes back to the 1950s, but it wasn’t available for the masses for a long time, especially due to the high cost and relative inefficiency of those panels. After the twentieth century, the cost started falling dramatically. One example is what cost you around 70$ back in the 80’s, won’t cost you more than a few cents nowadays.
But today, with the advancement of solar technology, you enjoy the flexibility of charging up almost any device off-grid, from a car battery to gadgets. Ever wonder how Solar charger works? Let me guide you through a brief and easy explanation.
- The basic is simple, the solar modules on the solar charger transform sunlight into energy. The process is known as the photovoltaic process. They work great when the sun is bright and shiny, but latest models even work fine with low lights and dull environments.
- The sun particles are known as photons. They have enough energy to knock electrons off silicon material used in the solar cells. Due to that, an imbalance of positive and negatively charged atoms is created within the cells, creating an electrical field. In short, the photons free up electrons and create a negative side, the protons on the other side create a positive side.
- When these two sides get connected through an external load, in this case, a solar charger circuit, the electron flow through the circuit and create electricity.
- One solar cell produces a small amount of electricity, i.e. one or two watts. To provide ample electricity, multiple cells are combined, and work together, which is called a module.
- Solar chargers don’t generally charge your devices directly, as they do not work directly with chemical batteries like Li-ion batteries used in smartphones. They come with their own battery, specifically designed for solar chargers. The battery stores electricity generated from the solar chargers.
- The battery is actually a better option for solar users. It offers off-grid electricity storage. The battery filters any electronic spike, act as a cushion between your device and solar charger. This makes the charging convenient and actually safer because your device gets all the power it needs in a single charge and at a right voltage.
How to Charge Solar Charger
If you don’t know how to use a solar charger, don’t let that refrain you from using that, because the procedure is really easy. Open the solar charger and put it anywhere flat facing towards the sun. Connect the USB cable to your device or the battery with the female USB port of the charger. Now cover your device because it is not designed to stay under the sun. Now sit back and relax.
After the charging is complete, fold the charger. You can use clips, like carabiner ones to hang the charger from a backpack, chair or your car and let it charge.
Benefits of Using the Best Solar Chargers
Sounds like a cliché, right? By now, you’ve probably seen and heard hundreds of commercials, billboards, news and documentaries regarding environmental pollution. All of us know the world isn’t like it was 50 years ago, and all of us are looking towards a global environmental crisis we don’t do anything to stop it.
It has already started to show off. The air is getting polluted little by little, in some cities, it’s so severe that inhabitants wear masks when they are outside. The average temperature is increasing, water level rising and cases of lung diseases are happening more than ever.
What’s the reason? We have been dependent on fossil energy so much that we kept on using it without searching for a more sustainable solution. A study says, from 2000-2012, consumption of oil increased is 176.5 tonnes. The USA gets 81% of its energy from fossil fuels, oil, coal, and gas. American industries and consumers spend 700 billion dollars to 1 trillion dollars every year for these fossil fuels. The rate we are going, there’ll remain only two options, 1- running out of fossil fuels, 2- A global disaster as an added bonus.
In 2008, almost half of the electricity needed was produced from coal. Coal is a cheap source of energy; therefore, the power plants use it. But what are the results? The Environmental Pollution Agency says that coal burning is responsible for mercury pollution, particulate pollution, and Sulphur-dioxide pollution, 59% of the latter comes from burning coals. The amount of pollution in the air is increasing day by day to fulfill our energy needs.
That can be avoided if we become careful from now. What we have to do? Using an energy source that can provide hundreds of planets energy needs like ours, a source that isn’t going to run out anytime soon, the solar energy. It is pollution free, cost-effective and we just need to borrow a little from this enormous power source.
Using a solar panel and solar charger can be the step we can start today. Not only they provide a good profit, in the long run, they provide flexibility and at the end of the day, you’ll be contributing towards a greener, more sustainable environment.
Reliability and Flexibility
The amount of natural resource is scarce. An estimate says the rate we are using in, oil and gas will run out within the next 50 years. Our population will reach around 10 billion by that time. A world full of people with the inadequacy of natural resources, we’re looking towards a perfect recipe for disaster.
What solar energy offers are complete availability from anywhere. No more standing on the oil pumps, no more worrying about fuel prices going sky-high. You can access the energy from wherever you want, as long as sun ray is available. You don’t have to worry about running it out because only a fraction of the suns energy is sufficient to fulfill energy needs of all humanity.
Another advantage is flexibility, freedom of movement. When you have a solar charger with you, you do not have to worry about external power sources. You’ll find the sun from almost anywhere. So you might lose your way on a forest, but as long as sun ray is available, at least you do not have to worry about being disconnected.
Easy to Use
One of the reasons we don’t feel that much excitement when we hear “Go Green” is laziness. Yes, you heard it right! Who would like to spend time on recycling and reducing carbon footprint while everyone else is doing just the opposite?
Well, the matter with the solar charger is, it is convenient for even the idlest person. You do not have to do anything except open it and wait for your device to charge. They are usually inexpensive too, for an extra energy source and freedom of movement, you have to pay around 100$.
Another benefit solar chargers offer is portability. Imagine you’re in a boat, and there’s no power grid near you. With portable solar chargers, you can trim off the worry. Most of them are lightweight, coming with a weight around 1 kg. So they will add just an insignificant weight to your backpack, with the benefit of liberty.
Application of Solar Chargers
Solar chargers can be used with several devices. You have to make sure the voltage and amp output the charger delivers are on par with the device. The application of solar charger includes but not limited to the following-
- MP3 Player
Uses of Solar Chargers
Solar chargers can be used for various purposes. As they are portable, cheap and fairly effective, you can use them for the following purposes.
- Everyday Use and Emergency Backup
Honestly, this is the main reason most people on the go use solar chargers. The thing with electronic devices is, they offer a limited running time with the power they can store, and it’s hard to keep track of that all the time. When you have a portable solar charger and battery, be it kept on your car, or backpack, solar powered phone charge will keep your phone running.
- Camping, Hiking, Travelling
Sometimes people go far away from localities because their audacious nature demands so. But that doesn’t mean they leave their electronic devices. In these situations, power outlets are limited and often unavailable. As devices like GPS is important when you’re on a camping or hiking trip, a solar battery charger gives you the necessary backup from anywhere sun is available.
Most of the motor boats have power outlets, sure. But simple boats like sailboats don’t have one. Having a solar charger can be the difference between running into trouble and getting help.
Best Solar Lights Buying Guide
The first thing to consider while buying solar chargers is the panels they use. Generally, manufacturers use three types of solar panels, Monocrystalline, Polycrystalline, and CIGS. While the former two silicon-based panels have been popular for years, the latter one is gaining popularity in recent times due to the flexibility it offers.
- Monocrystalline and Polycrystalline
The main material used in both is silicon. After all these years, silicon-based solar panels are still more effective than any other types. The difference between monocrystalline and polycrystalline is one is manufactured from a single crystal while another comprised of multiple crystals. Monocrystalline panels look black while polycrystalline panels give a blueish shade.
The difference is in purity, and mono panels are purer than their poly counterparts. Due to that, monocrystalline panels come with more efficiency (20% -22%) than polycrystalline panels (16%-18%).
Monocrystalline panels are more expensive polycrystalline ones, but they are more power and carry out better in low light conditions. That’s why they are still the most popular choice among the buyers. In early times, one problem with foldable monocrystalline solar chargers was the rigid nature of the panel, which lacks flexibility. But now, as rigid panels come with different suitable shape, the drawback is getting insignificant.
They are the new neighbor in the block and offers a lot of flexibility for on the go people. CIGS use thin-film solar panels technology, different materials leaping one over another. In this case, Copper, Indium, Gallium, Selenide are used, thus the name CIGS.
They are extremely lightweight and provide a great suitability to travelers and ramblers. These flexible solar chargers can be folded easilyrustand you can use them with more ease. Just put it over the stone, hang on the tent or keep against a chair, anything will do.
As for efficiency, they aren’t far behind from monocrystalline panels, and best of them can match their monocrystalline counterparts.
The only drawback is they aren’t as sturdy as silicon-based panels, they tend to degrade at a faster rate. But the choice is down to your situation, if you are going for a trip, nothing else can serve you better than a CIGS.
Wattage is the parameter that’ll tell you if your device is compatible with the charger. Wattage determines whether you can charge your devices quickly or take a nap during the process. A solar charger with 5-watt capacity should be sufficient for smartphone or MP3, but if your phone battery needs more than that, a 10-12 watt should work great.
Know your choices before you make a decision. A device like a smartphone can take 2-8 hours to get fully charged, depending on the wattage. Higher wattage, in the range of 14-21 watts can charge sophisticated devices like iPhone or Samsung Galaxy.
Some chargers come with the facility of adding additional panels. For example, if you have two 2.5 watts’ panels, 5 watts in total, you can add additional panels to increase the capacity. People with multiple uses of chargers will find this helpful.
If you need to power larger devices, say a laptop, you’ll need a solar a battery, separated or integrated along with the charger.
Integrated or External Battery?
This depends on your needs. Some solar chargers come alone, some along with integrated battery and others with an external battery. If you are using additional batteries for home uses only, strong batteries of the size of your phone, known as power-banks will serve you well. Once fully charged, they can charge the phone for 4-5 times. If you are on a trip and not likely to get any power-grid near you, then a solar charger with an integrated or external battery will come handy.
A solar battery gives you lots of freedom. You can charge it at home, the battery will store the power and provide you backup whenever needed. Even if the sun is not shining, you will be assured of battery backup.
Some chargers come with internal batteries, whenever you need, you just open the charger and let it be full. However, most of the time you won’t get a charging to keep the phone running for hours, but they come handy when you need to call 911 or send urgent messages.
If you use powerful and energy-hungry devices like the iPhone, you can think about external batteries. Some external battery charge single devices and some charge multiple devices.
Durable and Portable
As most of the people use solar chargers for traveling purposes, durability and portability are the key issues. There are solar chargers so thin and lightweight that, you can fit them between the pages of a book. Some chargers come with multiple panels, can be folded and kept in their own case. They usually are lightweight and can be tucked nicely into the backpack. Some come with carabiner clips so that you can hang them from your backpack.
You have to make sure your charger is durable. Fancy looking, weak chargers might be appealing for the eyes, but for outdoors you need something that can withstand the challenges of different weathers. They must be water-resistant, shock-resistant and robust to not get scratched easily.
If you are on a trip, hiking or camping, it’s usual that you have more than one devices. You might have a smartphone, a tablet, GPS or a camera. Having more than one connector will only come beneficial.
Most of the solar chargers come with 2 or more USB connectors. One for high amperage, power greedy devices and another for regular devices. However, note that having a USB port for smartphone or tablet doesn’t account for every other need.
For example, a camera that takes charge from a wall outlet, won’t be compatible with the USB connectors. It will need an adaptor to get connected effectively. Remember, any device that needs a cigarette charging port of 12 volts won’t work with many of the chargers.
Ease of Use
Solar chargers are used to make charging available and easy, not the other way around. So the chargers should come with convenient shape and features to aid the user.
Nowadays, critics and reviewers are giving importance to uninterrupted charging facility into a solar charger. Previously, when a cloud passed over a charger, or someone walked past it, the charging would have stopped and required to start manually. With “auto-restart” feature coming with some chargers, chargers can restart themselves if that happens. No need to sit under the sun and guard it, cheers!
Another simple, but regular problem is stashing the smartphone. Solar chargers need bright sun to operate, but that isn’t the case for smartphones. Some solar chargers come with stash pockets to keep your smartphone protected while charging.
Some solar chargers come with a clip so that you can hang it from your backpack. With a battery, you can keep it charging when walking, or hiking.
