    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 :)
    Suggestion
    - none

    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.

    Gutes Ladegerät zu angemessenem Preis
    -einfache Bedienung und
    -Koppelung mit Handy über Bluetooth mit der App „E-SYB“
    -über die App kann der Ladestrom eingestellt werden und zudem die Ladekurve/ der Ladevorgang beobachtet werden, was mir sehr gut gefiel und auch der ausschlaggebende Grund war, weshalb ich mich für dieses Gerät entschieden habe
    Suggestion
    -nach etwas über 1,5Jahren Gebrauch, brach bei mir innen die Rückholfeder des dritten Ladeschachts ab.
    Nachdem ich das Gerät geöffnet habe und eine Möglichkeit fand, die Feder innen wieder zu befestigen, gingen wenigstens wieder alle vier Schächte.
    -leider funktioniert nun kurze Zeit später die Bluetooth-Funktion nicht mehr, was ich sehr ärgerlich finde
    -Ende vom Lied, der Ladestrom lässt sich nicht mehr variabel einstellen und jeder Schacht lädt nun nur noch mit 0,5A. (Früher könnte man 2 Schächte mit 2A und die anderen beiden mit jeweils 1A fahren. Oder alle 4 mit jeweils 1A.) Zudem finde ich, dass es, wenn ich an dem Gerät während des Ladens rieche, etwas verbrannt riecht.... mal schauen, wie lange es noch dauert, bis gar nichts mehr geht...
    [GB hat mir eine Rückvergütung i.H.v. 8$ angeboten]

    gutes Ladegerät für 18650 Batterien
    ich lade damit die Batterien für meine mod sehr leicht sehr schnell am Laden die App funktioniert wunderbar über Bluetooth der externe USB um sein Handy zu laden ist auch sehr gut allerdings muss man dafür das Netzteil abziehen einfach super kann ich nur empfehlen
    Suggestion
    bis jetzt keine

    Good Charger for LiXX - batteries
    This is an nice charger for Lipo - batteries with a very good display.

    Fast charging for all Lipo types with also 2A in the outer ports.

    You can change all settings in the app or in the charger.

    In the app you can also see the charging curve.
    Suggestion
    No fast charging for NiMh / NiCd - only 0.25mA - an envelop can support 2A charging. So it will take some time longer to charge this types. It charges the NiMh to 1,5V and stop charging.
    2 of my batteries don't reach the 1.5V an were overcharged. For this type of battery its the "delta peak" charging better.

    Is it possible to get an new firmware over the app to solve the problem?

    And there is also an security question for the app.

    Why you need this permissions in the app:

    - make pictures and videos? - to make fotos from my batteries?
    - transmit identity
    - write or delete on SD
    - use Wlan (for update?)

    Why it is not in the playstore?

    So the BT and app function is to insecure and useless for me.

    If you can fix the problems the charger can get 5 Stars.

    Until now it is an good charger, not an perfect one.
