Ill be waiting for HKJs review, just like I did with each version so far. Im yet to buy one of their chargers, theyre close, but never quite there for me. I dont care about saving $10 so was not motivated by group buy deadline pressures.
The comment on Amazon is from a random user and should not be taken as gospel. I wouldn’t be surprised if the C3400 is the same as the C3100 V2.1.
I don’t like how they are having all these minor updates and different versions within a few months. I think it is better to update every year with substantial changes and a different model number.
The 3000 did get some software updates to fix the problem with current pulses. This made the current pulses small enough that the power supply could handle it, but they where still above 3A.
The 3400 probably has changed hardware to get rid of the current pulses.
At the current time I have not been promised any review copies of it.
I suspect that you are right though about it being the same as the C3100 v2.1. Someone realized that giving it a new name and label is a lot better way to clearly communicate that it is the new and improved version, and avoid people passing off old stock as new.
Or it could be as simple as they wanted to first use up all the cases that they had made up that said BT-C3100. I don’t think they expected to update the unit so soon after the release of v2.0
HKJ suggested that maybe there is an included hardware upgrade. From the Amazon site this C3400 has been in their hands since September. Is it possible OPUS could have made a hardware change that quickly after the release of v2.1?
Maybe it now possible to change the charging end voltage (3,6, 4,2, 4,35V) without opening the charger. It's crazy, that the feature is inside and not changeable without removing the screws.
Just emailed Robert ( rdana from ebay)
This is what he said……
The BT-C3400 is essentially the C3100 V2.1. This model number is exclusive to me.
Thanks,
I’m gonna buy one from him since it is the new 2.1 version.
