EL PARCHE DE LA HAT SE NESESITA CARGAR CON LUZ SOLAR O ARTIFICIAL NO BRILLARA POR SI SOLA SIN CARGA, TOME ENCUENTA QUE A MAYOR TIEMPO DE CARGA MAYOR LA DURACION DEL BRILLO EL BRILLO SE VA AGOTANDO POCO A POCO Y ES NESESARIO CARGARLA DE NUEVO. THE HAT PATCH NEEDS TO BE CHARGED WITH SUNLIGHT OR ARTIFICIAL LIGHT IT WILL NOT GLOW BY ITSELF WITHOUT CHARGING, TAKE IN CONSIDERATION THAT THE LONGER THE TIME OF CHARGING, THE LONGER THE DURATION OF THE GLOW.. THE GLOW WILL CONSUME LITTLE BY LITTLE AND IT WILL BE NECESSARY TO CHARGE IT AGAIN
