    Зарядное и Powerbank для лития
    Зарядное и Powerbank для лития.

    Вещь, конечно, удобная. В отличие от Miller-а, например, может использовать любые типоразмеры лития, насколько позволят провода.
    Да и компактнее будет. С плюсами всё.
    Минусы:
    1. Зарядное недозаряжает литий - всего до 4.13 Вольт.
    2. Powerbank при токе 1А просаживает напряжение до 4.84 Вольта.
    В принципе, это не страшно, но, к примеру, мой телефон Redmi 4X при таких условиях заряжается током в 0.43А, что очень долго (при напряжении выше 5 Вольт он может брать до 2 Ампер).
    Но из-за маленького тока КПД выше и аккумулятор "выдаивается" лучше, чем у Lii-100, к примеру.
    Вот такое неоднозначное устройство.

    Первый агрегат пришёл через 26 дней и оказался нерабочим от слова вообще.
    Менеджер предложил повторную отправку и через 2 недели я стал счастливым обладателем рабочего экземпляра.
    За такую поддержку клиентов магазину отдельное огромное спасибо.
    Suggestion
    Недозарядка и проседание выходного напряжения.

    Awesome portable battery charging tool
    Awesome portable battery charging tool, my old chargers are big and bulky, this one is small and portable.
    My old charger has a quick-charge function, so, I am not used it as a normal charger, just as emergency tool in our mountaineering, in case that we need to transfer the electric power between mobile phone and Li-ion battery devices.
    Suggestion
    NO, it is a nice tool.

    Convenient magnetic connector
    Check the seller’s picture, i was worried about the the magnet can hold the battery, but, after i tried to use it at the first time, i had worried too much, the magnetic connector is powerful than i much thought, of course, don’t swing it during charging batteries, the cable is not that strong.
    In a word, worth to buy
    Suggestion
    No storage case

    Great little charger for every body
    Got several Li-ion battery chargers before, this one is the most likeable.
    Very tiny size and very lightweight, almost take no space in my pack. It fits all size cylinder batteries, i don’t worry the matching problem, even i gonna buy another size battery some day.
    Suggestion
    None

    Suggestion
