A Solar power bank employs solar energy to produce electricity. This electricity can be used for different electrical devices and to charge batteries. Most of them are generally portable and can supply up to 48 volts and 4000-ampere hours. This is an article about solar power banks, how they work, the benefits and the various types.
In Brief, Solar energy is the electrical power that is derived from sunlight. The conversion of this power can either be directly using photovoltaics or indirectly through a concentrated solar panel system. These solar panel systems make use of lenses or mirrors to focus sunlight on a small beam.
When we talk of solar power charger, the name says it all; it is a battery storage unit of power that derives its energy directly from sunlight. They can be very useful during trips or when there are power shortages. They are becoming popular as each day goes by as more smart devices are being invented and they need more power to work and last for a day. Generally, the power banks act as a backup.

How Does Solar Power Bank Work?
Most people who own a solar charger power bank, do not know how they work and it is very rare to find a seller explaining to a customer how these gadgets work. Solar power banks have special lenses that concentrate the sunlight on a small beam in order to charge the batteries inside. The battery has a circuit which controls the power flow obtained from the sunlight. These batteries store the electrical energy converted from the sun, which is later used to charge various electrical devices like mobile phones.
Benefits of Using a Solar Powered Battery Charger
Solar power banks are the most energy efficient and economical devices that someone can have. They no doubt make life so much easier. There are numerous benefits that they bring to our lives. They include;
1. They can charge without any electrical input. This means that they have no associated costs that they bring along.
2. They can be used anywhere, You just need to have access to sunlight.
