    UltraFire WF - 139 Cargador de Batería
    Tras recibir mi orden nº 18072800933705460122, uno de los tres cargadores ha llegado defectuoso. Aparentemente es un fallo de conexiones internas. Presenta cortes de alimentación intermitentes y además se escuchan como unos chasquidos internos. Comprobados los otros dos cargadores, funcionan perfectamente.
    Decir que el producto no ha sufrido ningún golpe brusco, ni ninguna caída. He enviado un ticket y pasadas 48 horas aun no tengo respuesta.
    También decir, que no suelo tener problemas con los productos servidos por Gearbest. Pero en esta ocasión el servicio postventa se demora.

    Ótimo carregador.
    Este carregador de baterias é excelente.
    Ele é compacto,prático e carrega as baterias rapidamente.
    Uma outra característica deste carregador é que ele vem com um plug para se conectar com o cabo.
    Outra vantagem deste carregador é que ele é de pequenas dimensões,podendo ser facilmente transportado dentro de um bolso.
