Solar energy: is it worth buying a solar power bank? | News

This is how a solar power bank works

A solar power bank is an electronic device that converts solar energy into electricity, storing it in a battery and delivering it to other devices as needed. As the Solaranlagen-Portal explains, the stored solar energy can be used for all kinds of devices, either directly or to charge their batteries. In general, such power banks are used where there is otherwise no power, or by users whose hobbies include long trips, camping, hiking or other outdoor activities. Among the devices that can be charged with such a solar power bank are, among others e-book readers, smartphones, notebooks, tablets, MP3 players, iPods, digital SLR cameras and mobile speakers.

As there are many different manufacturers in this market segment, who in turn have developed various concepts and designs, there is a whole range of different models and types on offer. These include small, portable models that are ideal for charging smaller devices such as cell phones, iPods, etc., as well as fold-out models that can be placed on the vehicle’s dashboard and connected to the cigarette lighter, for example to charge the battery for charging vehicle battery.

These are the benefits

Solar power banks have a number of advantages that make them a desirable alternative for some users. For example, these devices use photovoltaics, i.e. free solar energy, which makes solar power banks a much more climate-friendly option compared to conventional devices. According to the portal solar systems, the production of solar cells and batteries today, due to the practice of mass production, uses much less energy, which can certainly be recovered through long-term use. Besides, the solar powerbanks can be used everywhere, for example while hiking, just clip them to a backpack and then charge them while hiking. Another advantage is compatibility: any device with Micro-USB support can be charged via solar batteries.

Another advantage of solar powered powerbanks is that they are very compact and not too burdensome in terms of weight or size. This makes them a great choice for long journeys or trips to the countryside. It is also worth mentioning the backup charging system, which will be of particular interest to people who want to be well prepared for potential disasters. For example, in the event of a power failure, devices provide a small source of backup power because electronic devices can be recharged even when no other power source is available.

How much is an environmentally friendly alternative?

Now, of course, the question still arises in what area are climate-friendly power banks priced. According to the Solaranlagen Portal, the price of these devices depends on various factors such as battery capacity, solar panel technology and brand. The price range for solar batteries with a capacity of 10,000 mAh to 20,000 mAh is between 20 and 30 euros. In the case of larger capacities, over 200,000 mAh, prices largely depend on the quality of the device.

When you enter the realm of really big capacities like 50,000 or 100,000 mAh, you start having trouble trying to find combinations that have integrated solar cells, although there are also devices where the power bank and solar panel are separated. Whether you can charge a certain electronic device with a suitable power bank depends on the type of USB port. Most power banks have a universal USB output, but some have a micro USB or Type-C charging port. Therefore, when buying, it is worth paying special attention to the type of port.
