A battery charger with wireless technology, meaning you can recharge your smartphone simply by placing it on the surface of the device without having to connect it via a cable. It uses Qi standard and works via magnetic induction, with an energy emission of 5W. The charging base is an ultra-slim, lightweight plastic disc measuring 10 cm in diameter, fitted with a micro USB port and a small LED light that comes on when the battery charger is connected to a power source (wall socket or laptop). This model also features four additional USB ports to charge several devices simultaneously. The entire surface of the plastic disc can be customised with graphics and logos using silk screen-printing, CMYK printing and LED printing, a technique that creates layers of colour with a relief effect combined with the back-lit LED light. The different colour densities create special light contrasts that lend the chosen graphics more depth. This device can also be used to charge smartphones that are incompatible with wireless technology by adding a universal module to the product and connecting it to the micro USB port (in the “accessories” category of the configurator).
