Initially available in one, and half watt configurations, solar charger mats from G24 Innovations power up a similar range of handheld electronic devices. Flexible, lightweight, dye-sensitised thin film solar cells have been incorporated into foldable mats and even panels on backpacks.

Users can start by buying small units, adding modules to give extra capacity when needed. Starting at around €16, the first mats are already on the market.
