Pros:
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
Cons:
no discharge test function, durability will be yet to known (its a new product).

Pros:
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. https://www.youtube.com/watch?v=1jZnNjBEd8Y (video presentation)
Cons:
Doesn't support discharge and test of the bat.

Pros:
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.
Cons:
none yet will have to wait to see if it performs over a long period of time.

Pros:
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.
Cons:
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.
