You can use the battery for all kinds of products, such as MP3 players, cameras, toys, clocks and remote controls. And not forgetting or our DIODER which is a series of decorative lighting that you can put, well, anywhere you like and however you like. You can put strips and spotlights with built-in diodes that change colour in your bookshelves or around the frames of your pictures and mirrors. The whole idea is to make it playful and fun for you to create atmosphere and personality in your home. And with the LADDA battery charger it allows you to charge up to four batteries at a time.
