Only 6 months after launch of the first public solar mobile device
charger in the city of Belgrade in 2011, a group of Serbian students called "Strawberry Energy" invented a new portable solar charger for mobile phones in public places.

And all visitors for the ATP tourney Serbia Open this year can have chance to meet the solar charger.

More than that, they can also learn about renewable energy while recharging their mobile devices.

Lifestyles has the story.

Using clean and ecological energy, the solar charger transforms energy of the sun and uses it for charging all kind of mobile devices in public places.

Improved version is smaller, portable and can be easily transported and set-up.

After being firstly presented in Brussels as the winning student project at the Sustainable Week in 2011, the public solar charger was installed in the Serbian city Obrenovac, and soon after in Belgrade, where it had over 85 thousand users so far.

The Strawberry Friend, a smaller improved version is now introduced at the ATP tournament Serbia Open on 29th of April, where it will be available until 6th of May.

According to Milos Milisavljevic, the founder and director of Strawberry Energy, it aimed for large public events and festivals, where visitors can easily recharge their mobile phones and other electronic devices.

Installed application is imagined as an interactive tool that educates about renewable sources of energy and entertains users with several games of quiz while waiting for their devices to charge and get ready for use.

"Here you can choose one of three inside apps. The first one is interesting fact. We can select the field of facts we want to learn about, for example we can choose energy and then we can choose for example renewable energy sources and then we can read more about it, learn new information about the renewable energy resources."

Strawberry Energy is the company of eleven students and graduates, working on developing technologies based on renewable sources of energy, and educating about ecology and environment protection.

More than that, the company also plans to install public solar chargers in four other cities across Serbia this year.

"It has been only six months from our first introduction of big Strawberry Tree, which was installed in Belgrade in the city center, and right now we are presenting new Strawberry solar charger. It is called Strawberry Friend and it's behind me. We learned some things from the big Strawberry Tree and implemented in the new Strawberry Friend. It is smaller, lighter and more portable solar charger than the previous version. The main idea for Strawberry Friend is to be used at events, like fairs, music festivals, where lots of people don't bring their mobile phone chargers so Strawberry Friend can help them to recharge their portable devices like mobile phones, portable players, tablets, and they can use energy from the sun to recharge their mobile phones and to have a part of sun in their pockets." 

The young Serbian company is now making efforts to develop new ways to implementing renewable energy sources in people's daily life, most importantly, they believe solar energy and other clean energies are crucial for the future.
