A great way to save on energy is to thinks of ways and products as how we can conserve energy. The DIY phone charging dock by Alberto Ricci Bitti is a great invention that everybody can do at home. It has the ability to cut off energy usage when not charging without the need to unplug your charger from the socket. All that you need is a power cord, lever switch, power socket not the wall mount type, faston crimp with full insulating sleeve, small box with hinged lid, insulating material, straw and felt-tip pen, packing sponge, phone charger, faston crimping tool, glue gun, insulating tape, scissors, blade cutter, and a screwdriver.
