12V DC to 220V AC supply
I have a emergency light with battery back up. its lights have gone out so i want to use its 12V dc power to transfer to ac power to backup a media converter, wifi router and mobile charger. Please, i want a detailed process of building this system. how much time could i get backup? i need a instrument and parts list for this project. i have uploaded the pictures of my light and specifications along with it.
