    My order arrived in good condition. This is the second Klarus charger I own, the first being the C8 model. I am extremely happy with the charger and like the fact that I no longer need multiple chargers to be able to charge 1 AA and my vape batteries at the same time. It is an extremely good value for the cost of the unit compared to any other charger that I have been able to find that does the same thing. Highly recomended.
    Nothing negative on either unit i've purchased

    i4 для нищебродов
    Универсальный зарядник, поддерживает самые распространённые типы аккумуляторов. Практически полная копия (и по виду, и по характеристикам) Nitecore i4, но дешевле (брал на распродаже за $9.99)
    Если заряжать одновременно 4 аккумулятора - зарядный ток будет всего 375мА на одну банку, что маловато.

    Good universal charger
    Низкая цена
    Универсальность (зарядка всех типов батарей, без хидромудрых настроек и лишних нажатий) - отлично подойтет не сильно разбирающимся в аккумуляторах людям
    Встроенный блок питания
    Поддержка LiFePO4
    Хороший ток заряда (750мА для 1-2 каналов)
    Высокий ток для зарядки ААА аккумуляторов

  • Roman
    Покупал как зарядник для батареек 18650(для электронной сигареты)
    Со своей задачей справляется отлично.
    Заражает не так быстро, как хотелось бы, но и не та цена, чтобы заряжать каждую батарейку 1.5 амперами
    немного заедают салазки для батареек, когда их оттягиваешь
