    My review
    Color:Black
    Pros:
    This is a dual channel usb charger with automatic current select and a simulated CC/CV charge profile. It has a usb pass through connector, making it possible to charge two batteries and a phone without moving wires around. With the switch it is possible to select what get charged first: batteries or phone.
    To handle two batteries a fairly powerful usb power supply/charger is needed.

    The possibility to charge two 18650 with 1A on usb is rather impressive, in praxis the charger cannot do it, but will be slower. The lower charge current is useful for smaller batteries.

    I know a couple of times where I would have liked a charger with pass through function, but I would usual also like a power bank function at the same time.

    It is a good charger, but I wonder how useful the pass through function is.
    Cons:

    Pros:
    Perfect for charging on the go. With the micro usb it's perfect for power banks or any micro usb phone charger.
    It's a lot smaller than it looks on the description photos at gearbest. The display is nicely lit and I'm loving the percentage indicating the charging progress. When your drained batteries it basically tells you how much "juice" they can still hold making it easy to assess when they become useless.

    overall great product, highly recommended.
    Cons:

    Mr
    Color:Black
    Pros:
    This is a neat little charger that packs down neatly and the intelligent charger aspect to it takes a lot of the mystery out of the charging and the health of your batteries. The device itself is well build and feels like a quality item and is a long way from the kind of cheap chargers that sometimes come free with some torches.
    Cons:
    It might have been nice if it came with a pouch or plug but that is just nitpicking.
