A wallbox is a high-performance power socket for your electric car. Smaller devices can be charged in a relatively short time using a standard charging station. Depending on the model, it can take several days to fully charge an electric car at full charging power via a domestic socket. No socket can endure that for very long. It will overheat, the fuse will blow and your car won’t get charged. In the worst case scenario, the cables could catch fire.
It is a much better idea to use a wallbox for charging. It is not only a safer option, but also charges your electric car up to 10 times faster than at a conventional domestic socket. An e-Golf, for example, will take 17 hours to charge on a socket and just 5.5 hours on a wallbox with a charging power of 11 kW. The difference is even bigger in a Renault ZOE. Once depleted, the ZOE needs 25 hours to charge on a conventional socket. On a wallbox, it takes less than three hours to recharge the ZOE.
