First you need to decide on the installation location. For public places, we recommend contacting us for advice. If you need a station for individual use at home, then you need to know how much power you can allocate. If there are no restrictions, we recommend choosing 22kW, if the power is not enough, then 11 kW. If you need more information, contact us, we will help you find the device that you need. The Contacts section is located at the bootom of each page of the website.
