Opus BT-C3100 LI-ion NiCd NiMh LCD Smart Intelligent Battery Charger with EU Adapter - Black

I think it comes with an EU like in most photos, with a US adapter.

Taken from post #49

Link in the title goes to “Opus BT-C3100 LI-ion NiCd NiMh LCD Smart Intelligent Battery Charger with US Adapter - Black”
Gearbest has EU version either but it is more expensive now ($56.99 vs. $59.14), and it’s unclear whether special price is coming for both versions of just US.

:~ Sorry for misunderstanding. You mean it is EU or US?

jealous57, thanks. Now it’s clear :slight_smile:

Same Group Buy for both configurations

If HKJ gives this the nod (after his second review) over the i4 I will one

done and done

Thanks

I’ll take one if HKJ can confirm the fixes. Emailed Dora.

That would be somewhat disappointing, as those adapters usually make the plugs huge and are sometimes loose fitting.

I’m in for 1

If the problem is solved, I am also in for 1. Will wait on HKJ to test.

The improved version will show 2.0 after power up for 2 second and then make full segment display turned on. This is the way to tell the difference between HKJ’s first reviewed version which has no version number displayed after power up. In future, if we make any improvement, we will have this version number updated reflecting the change.

Thanks for the clarification, Henry.

Edit: Henry Xu is the chief engineer of Opus Instrument, the maker of this charger

Same here :)

I am also in for 1 piece (EU version)

Thanks for taking the time to reply to us personally, that speaks volumes about you and the business you represent, most appreciated.

But I have to ask, so with the current fist and second version, unless sellers switch them on and then inform us, we wont know until be buy one and switch it on ourselves if its the revision model? IN essence a lucky dip?

On that, did you read HKJs review of the item yourself or just the highlights and then responded to those?

Please read post # 64, just in case you have not.

Thats what led to the questions. It doesnt answer them.
Well one is answered. It IS pot luck whether or not you get the corrected version, you will ONLY know once you have it in your hands, not before. It must be switched on to see the firmware revision number. Although Dora could switch each one and tell us. But I have not seen that posted as the case so Ill assume its not the updated version until I hear differently.

And the other question is not answered as only Henry Xu can answer it. Basically in Point #4 of post #64 Henry Xu disagrees with HKJs assessment. I was wondering if Henry had actually read the review, or just a list of highlighted points that someone may have sent to him.

Im not saying he is wrong, but it would be nice to know if he disagrees based on the review, or a dot point.

Well, the dealer would actually have to plug it in and watch the display show 2.0 before shipping it. (although to some dealers it’s not as easy as it sounds, lol)
