    Mr
    Very pleased with this Smart Power Bank. It works well and does what it promises. I have not used it a lot to charge any of my devices but it did charge my phone quite quickly and well. Primary use is as a 18650 battery charger. This feature is great. It detects incorrect polarity and charges batteries individually and gives a nice detailed display of the charge and progress. A very good multi purpose Smart Bank and Charger. I highly recommend this product.
    Suggestion
    Batteries left inside the Charger Smart Bank do discharge a bit over time if not in use.

    Good quality
    Nehmen für tourismus auf die empfehlung von ein freund elektronschika. EINE große sache, vorteile: 4 unabhängige kanäle für lade, BATTERIE kann insert jeder, was sie haben, eine oder mehrere, leistungsstarke. Wenn lade zeigt wie gebühren jeder der slots auf das prinzip der "run" Sticks. Wenn sie die verbraucher verbrauch in milliamps jeder von yusb port separat. Wenn mit einer beliebigen anzahl von einem der 18650, einfach Ändern batterie als entladung einzeln oder alle 4). Dieser fall mehr praktische als slim mit der anzahl 20000 und die tatsächlichen 5-8 к)).

    TOMO M4 Power Bank
    Реально рабочий повербанк TOMO M4. Однозначно мне понравился. Удобная крышка-задвижка для демонтажа и установки батарей. Но как мне показалось...... не до конца (2.8V) разряжает батареи, где то до 3.05-3.10 но это тоже нормально, т.к. до 2.8v батареи уже садятся буквально за пару минут. В Целом повербан своих денег стоит, и к покупке рекомендую. Хотя на распродажах уже можно купить сяоми повербан на 10к махов по распродаже или скидкам по купонам за эти же деньги лишь доплатив пару баксов.
    Suggestion
    Наверно цена. т.к. уже доплатив пару баксов можно купить полноценный повербанк сяоми на 10к.

    Отличная штука!
    Данным девайсом уже не первый день пользуюсь и впечатления только положительные - заряжает ни долго и ни быстро - нормально. Индикатор зарядки функционирует. Как и само устройство может быть павербанкой, так и заряжаться от других устройств.
    Suggestion
    Плохого сказать нечего.

    Good Value
    Just add your own batteries and you have a power bank to carry or can be used to charge the batteries for use in other things Screen shows status of each battery when charging or when switched on with no load connected. When charging devices from this it lets you know the current that the device is drawing. Two outputs, one 1 A and the other is 2A

    4x18650 Charger/Powerbank
    kleines Gerät mit mehrfachem Nutzen: - lädt bis zu vier 18650er Akkus - Powerbank mit 1x 5V 1A und 1x 5V 2A USB - aufgrund der geringen Größe auch als Transportbox für Akkus nutzbar informatives, beleuchtetes (abschaltbar) Display, zeigt beim Laden graphisch den Ladestand/-vorgang sowie Verpolungsschutz der einzelnen Akkus und beim beim Entladen Volt und Ampere an der jeweiligen Buchse an gute Verarbeitung und ansprechendes Design
    Suggestion
    mitgeliefertes USB-Kabel mit ca. 24 cm relativ kurz, könnte sich aber auch als praktisch erweisen ;)

    PowerBank
    There are already two of them, one white is a black one. Easy to fit in small pockets. With a very good battery can use it very long time. I used to phone, wristwatch, and wireless earbuds to charge. Daily!!
    Suggestion
    I've been using it for a long time, reliable.
