    Bluetooth enabled 4amp 4bay Charger
    this is an interesting price point for a modern charger unit.
    it has CC and CV charging, unlike OPUS. 2amp charge on 1st and 4th bay and 1amp on 2nd and 3rd bay (better than NiteCore)
    It shows all 4 batteries charging status in once screen unlike Liitokala Lii - 500.
    It doesnt have discharge/tester functionality but you need to ask if you need that feature.
    But it has a cool mobile app for iOS and android that allows you to see charging graph, status, change current and turn light on/off - which i think at this price point its cool and a better upgrade to NiteCore d4
    Suggestion
    no discharge test function, durability will be yet to known (its a new product).

    ESYB E4 Bluetooth Battery Charger
    Is rare within this price range to find charger that can charge whit 2A in two channels and 1A in four channels.
    Doesn't support discharge and battery test but it has Bluetooth monitoring via app.
    Great build quality, fair price and effective charger.

    ESYB E4 Bluetooth App LCD Battery Charger
    + Good build quality,
    + Automatic recognizes battery types
    + Easy to use Bluetooth function
    + Easy to use Android app.
    + 2 slot for fast charge 2A, 2 for 1A max

    If it had a discharge and test mode - it would be a ideal charger :)

    next gen charger
    this is what future chargers will have, total control with app, you can change voltage of charge to a max of 2amp which means a 2 battery charge will be quicker than every other battery charger except the efest luc blu6. this charger is great its better than the xtar v4 that I own and is quicker.
    Suggestion
    none yet will have to wait to see if it performs over a long period of time.
