Today, everyone carries around with them one or two energy suckers. Whether smartphone, tablet, notebook, the battery is constantly in need of replenishment. When there’s no outlet nearby, people like to grab the power bank, but what if it’s empty too?
Many now like to use solar powerbank for such problems. The little helpers have a decisive advantage: they do not need a socket for charging. On or in the devices small solar panels are installed. With these it gradually replenishes its memory. Most of the time the Power Banks are lying around somewhere waiting for their deployment anyway. Feeding them with solar energy saves not only nerves but also money.
What advantages do solar powerbanks have?
Particularly environmentally conscious users are always looking for alternatives to make their technology a bit more environmentally friendly. The switch to solar energy is very convenient. But not only conservationists are interested in this charging method. Although charging with solar energy takes longer than supplying the battery directly from the mains, there are no additional electricity costs.
The most sensible are most models for smartphones and weaker tablets. Strong tablets or even notebooks draw too much power in relation to the charging rate. A smartphone, on the other hand, often only needs to be charged once a day. In the remaining hours, the solar powerbank has enough time to recharge.
The disadvantages of solar powerbanks
Of course, the dependence on solar energy also has its dark side. The best results are achieved by a solar powerbank with cloudless sky and bright sunshine. The user should also pay attention to a good alignment of the device with the light. However, as soon as the sky is overcast, the charge rate collapses drastically. Of course, this technique is useless at night. Even in winter, the performance of a solar powerbank drops, because the intensity of sunlight decreases sharply.
A solar powerbank gives the user a certain independence and in everyday life it is a practical But the required conditions are sometimes difficult to produce. However, this is not a problem with most devices. In general, a solar powerbank is equipped with a USB port, through which the device can be charged in case the sun does not want to show up. If the matching connector is not available, it can often be retrofitted with adapters.
Equipment and prices
A solar powerbank generally has the same standards as any other power bank. Numerous devices with different capacities are now on the market. Like their relatives without solar panels, they weigh on average between 200 and 500 grams. The manufacturers try to use as much of the surface as possible to generate energy. The larger the solar panels are, the faster the device recharges with the help of the sun.
As solar panels are getting cheaper and cheaper, more and more power bank models with this equipment are coming onto the market. The prices vary greatly. Cheap devices are available from 15 euros, but even those who want to spend much more, is easy to find.
