Smartphones have entered life so tightly that it is already difficult to imagine how you can do without this assistant. A smart device is a second memory and connection with the outside world, as well as a source of endless information. Unfortunately, the battery charge of a smartphone has been and remains a sore spot for modern devices.
Most modern devices are designed to work on a single charge for 8-10 hours. If we are talking about standby mode, these indicators are more serious. In general, from 24 to 36 hours. This time is very short. Let's remember the good old black and white devices that were able to work for several weeks on a single battery charge. These indicators were then at their best, but telephones did not know how to do anything other than making voice calls.
The whole problem of modern smartphones is that the manufacturer for some reason focuses on the constant proximity of the electrical network. This is good for an office clerk, but if a person leads a more active lifestyle or works in a traveling job, they cannot use a modern smartphone all the time. You constantly have to be afraid of the discharge.
To solve this problem, the so-called power bank was invented. This is an external battery that can charge even a powerful smartphone two or three times. It would seem that a solution has been found. However, this battery pack is also discharged sooner or later. For example, if you take it with you on a fishing trip or on a hike.
But here, too, a solution was found. Manufacturers began to produce devices that, without exaggeration, allow you to charge your smartphone from the sun. This is a solar battery that is connected to an energy storage device (a regular battery from a power bank). This allows the battery to be recharged from sunlight. The device has become a real salvation for all tourists and traveling workers. After all, even on cloudy days, if you hang this energy source on a backpack, it will charge the battery by at least 30%. This is enough for normal smartphone use.
These power cans with a solar battery are manufactured in a protected case and are not afraid of falls and water. This means that you can try to charge it from the light even in the rain.
You can buy such a device on aliexpress. They are relatively inexpensive. This gadget, depending on the modification and the chosen store, will cost from 800 rubles.
Using the charger is very simple - just place it under the light source. The light activates the built-in solar battery, which begins to recharge the built-in rechargeable battery. The rechargeable battery charged by the light is already stably recharging our phone. Charging takes place even on cloudy days or under an electric lamp. Some chargers are equipped with a charge and discharge indicator. Focusing on these indications, they should be used.
In fact, this gadget allows you to charge your smartphone or mobile phone directly from the sun. To some extent, this brings us to the use of a perpetual motion machine and environmentally friendly technologies.
