    UltraFire GD5421 Li-ion Battery Charger - BLACK
    Брав для тривожного рюкзака + в походи (про всяк випадок) щоб заряджати акумуляторні батарейки від динамо-зарядки. Є мініUSB та індикатор, це й все. Також можна підключати до мобільної сонячної зарядки або Powerbank. Заряджати можна батарейки-пальчики і менші.
    Немає звичайного USB.

    Mała, lekka, kompaktowa. Zmieści się w kieszeni edc. Ladowanie z micro usb. Prąd ładowania 0,5 A. Szybka nie jest, ale to lepiej dla baterii. Polecam.

    Ultrafire charger
    Small, portable yet very effective charger at an exceptionally low price. Standard smartphone charger works well with this.
    Requires cable and adaptor
