Review: Tutto perfetto
Review: Producto sencillo y a buen precio que permite usar accesorios eléctricos (nevera en mi caso) con el coche apagado sin temor a vaciar la bateria con el problema que esto puede acarrear. Desconecta el aparato automaticamente tan pronto como la tensión de la bateria baja y esto te permite olvidarte de controlar el tiempo que llevas conectado.
