Solar Chargers, Do they work? One of the most significant modern “evils” is to depend on the battery of our smartphone to communicate, work or study. While we await the arrival of some future “almost infinite battery,” we have to sharpen the ingenuity to keep the battery running all day, especially if we are not at home.
The good idea is to use efficient and practical resources such as renewable energies, such as portable solar chargers. Solar Chargers logically, get charged by the abundant sunlight and allow us to keep the mobile phone charged using Solar Energy.
How do solar chargers work:
Simple operation, but with limited practicality.
The process of a panel or photovoltaic solar panel (the one used in a portable electric charger) is as simple as it is effective: The miniature boards are generally composed of silicon, an ideal material for transmitting electrons, and can be monocrystalline (high quality) or polycrystalline (which provides quality and inferior results).
However, one of the significant limitations of the panels. Apart from the material used in their manufacture, is the small amount of energy that can be collected by individual panels. Since a panel of about 10 cm in size would only receive 100 mAh every hour. You need to join a certain number of panels connected in parallel, or have large panels, to be practical and fast when charging a standard smartphone battery. Which is usually around 1800-3000 mAh capacity. My mobile has 5000mAh (
The use of solar panels in mobiles:
There have been mobile phones that have coupled solar panels in its housing, such as the Samsung Guru E1107, that had a free house with built-in solar panels A slightly less sophisticated terminal that had integrated solar panels directly on its lid.
To get an idea of what solar power contributed to these terminals. the Samsung Guru E1107 panels simply added 5-10 minutes of voice talk for one hour we kept the terminal aimed at the sun. The construction of these panels was not very advanced. Keep in mind that adding an efficient panel directly to a mobile phone dramatically increases the cost of the device.
Foldable Solar Charger
The most effective solution to benefit from this renewable energy in mobile devices, returning to the main issue we proposed, is to have an external charger that uses panels.
Of course, we have many types of solar chargers on the market, according to our needs, from large panels with the ability to connect multiple USB, as is the case of the JOOS Orange, to small chargers, even folding, or as compact as the IFITech SLUSB6-208 Solar Flexi Portable Charger.
The vast majority of solar chargers include a battery where they store the energy collected by the panels. Something tremendously useful but inefficient ecologically speaking. Since we will have to replace the battery approximately every two years, with the consequent contamination that this produces (which counteracts the ecological philosophy of the panels themselves).
If the existing options do not convince us. We could even build our home solar charger. Tthanks to examples like the one shown by this video, very educational by the way:
Is it worth using a solar charger?
After the components of the photovoltaic panels used in solar chargers and the variety of chargers existing in the market. We can stop to deduce for ourselves if it is worth or not acquisition.
The truth is that, for typical regular users, it has more inconveniences than benefits. Bear in mind that charging a battery of about 2000 mAh with the help of a single mini-panel that charges 100 mAh per hour would take us a whopping 20 hours. Something physically impossible to perform (due to lack of sunshine) if not was for the help of the included batteries.
Foldable solar charger
We must take into account, as a decisive fact, that external agents have a significant influence on the continuous operation of a solar charger. If there is no sun, there is no charge. If the sun is obstructed by clouds or the rays that strike the panels are not perpendicular, we will not have a very fluid load either.
Do we live in a city and do not have time to look out the window? Possibly a solar charger is not the best for us. Taking into account that in most cases it will be easier to find a plug than a place to enjoy the fullness of the sun during the hours you need to charge the device (which will be enough, more than 5 hours normally). Best Power Bank in the budget.
Do we like to travel or enjoy outdoor activities? Then it may be that it makes more sense to acquire this type of chargers. Also, it is much more ecological than using any other charger. We will be taking care of the environment.
