Sunslice is not only the smallest solar charger in the world but it has also the best size-to-power ratio. With the rated power output (announced by the solar panel producers) of its solar panels of 3.6 Watts, it exceeds the power output of much bigger solar chargers.

For this comparison, we wrote down the theoretical power output of the solar panels instead of the real power output of the charger. Our competitors only disclose the rated power of the panels, rather the true power output which is slightly inferior. To make it a fair comparison, we compare them with our solar panel's rated power output in the image above. However, we prefer to announce the real power output of 3 Watts in the general description of the product for transparency.

By pledging on our Kickstarter campaign, you make this venture possible and we really want to thank you right now. This is why we created the Sunslice of Fame hanging in our office. On it, we will write the name of all our backers all along the campaign.

The co-founders of Sunslice are Geoffroy Ghion and Henri Gernaey.

We are two engineers from the Louvain School of Engineering, obtaining master degrees in civil and electromechanics engineering respectively. The ambitious idea of creating a solar charger in the size of a credit card surged from a conversation with an explorer who sought an optimal solution to charge his devices during his expeditions and his daily life. We accepted this challenge with the will to use our technical and business development background to find innovative and green solutions to important energetic problems.

Sunslice is the smallest solar charger in the world, but also the first of a long list of green technical solutions we want to develop and bring to the market.

More than two complementary associates, we are also very close friends with this common objective.

Quentin Lavigne, Louis Vielle and Denis Schollen are respectively in charge of web-marketing and digital development, audiovisual production and graphic design. We met them at university and they joined our team to help us in this challenging but awesome venture.



We are lucky to be advised by Vincent Werbrouck, mechanical engineer and expert in business development. He was the Chief Innovation Officer at Magotteaux, the world-leading supplier of process optimization products & services for high-abrasion extracting industries.Sunslice has also been co-designed by François Royen and Laura Hong from IOL Strategic Design. Special attention has been given to the industrial feasibility of the product, which will have to be produced in large quantities, for Kickstarter and later on.

Sunslice participated on November 14th, in Bonn, to the official launch of the World Alliance for Efficient Solutions, established by the Solar Impulse Foundation and chaired by Bertrand Piccard. The official launch corresponded also to the COP23, the 2017 UN Climate Changes Conference which takes place from 6 to 17 November 2017 at the World Conference Center in Bonn.



The World Alliance brings together the main actors involved in developing, financing or promoting products, services, processes and technologies that protect the environment in a profitable way.

The 1000 most promising solutions will be selected and labelled as Efficient Solutions.

The most innovative and durable solutions in the world were thus attending the event yesterday. It was certainly very inspiring but it most of all could lead to promising collaborations in the future.

No need to be one of the biggest companies to do its bit. Ambition, perseverance and faith are the keys to a better world.

"Work Hard, Dream Big" !



We came back Saturday 11th of November from an extremely interesting business trip in Lisbon, where we have been attending Web Summit, the largest tech conference in the world. We had our own booth and the feedback we got from the visitors was very positive. Promising partnerships came out of the discussions with attending startups and companies. Sunslice’s future in terms of investment and new innovative products is very promising. It looks like this Kickstarter campaign will not only lead to the launch of Sunslice’s production and the production of a minimum of 1000 units, but also to new collaborations and ideas. Our mission to bring Energy Anywhere is on the right track and this gives us the motivation to give all our own energy to this project ! Thank you for helping to make this big dream a reality !
