General HintsEcodesignUniversal Connector at the output of charger or power

supply (USB-A in L1000)Detachable cable as far as possible anywhere

recharge Increase reuse ability of charger and power supply by

charger lifetime increase and cable replacement ability use flexibility with the most device as possible power range, voltage choice

Optimization Options: multi-outputs, Home DC network, back-up, Renewable Energy, …
