Powerbanks, USB-Cable
EnergyCircle shows several power banks arranged in a circle, charging and discharging each other. The power bank charges the one behind it and is charged by the one in front of it. The chipset in the devices recognizes a connected device and automatically starts the energy transfer, with LEDs showing the current charge level and charging status.
Batteries and mobile energy have been around since the 19th century. As mobile devices have become smaller and smaller, the capacity of the batteries built into them has also decreased, leading to an increase in the use of mobile backup batteries, known as power banks. The most common reason for this is the user’s physical distance from an available power outlet during prolonged use of the device, when one battery charge is not sufficient, for example during a day trip.
EnergyCircle is a closed circuit that sustains itself through the prior supply of energy, but eventually shuts down due to the waste heat generated during transmission and the associated energy loss. If one component fails, a domino effect occurs.
