We reported about the solar bonsai-inspired charger concept by Vivien Muller back in 2008 and the product has now evolved and is being produced by a small family-run company. Dubbed Electree, the solar charger features leaves of photovoltaic panels that allow users to recharge mobile devices using renewable energy.
The structure consists of 42 solar cells and the energy produced by the panels is stored in an onboard battery. Once charged, the battery can feed mobile devices via a USB port. The charger is released in a limited edition of just 20 specimens.
