Difference between Opus BT-C3400 & BT-C3100 v2.1?

Upon further review I would definitely get the adapters. It works but connectivity can be a problem at times. I just moved the unit slightly and it shut off. A proper 2.1mm connection will make it much more secure.

I got a 10’ cable 5.5mm X 2.5m female to 5.5mm X 2.1mm Male coming on Friday!!! :sunglasses: YES,IT IS 10’!! But I can use it for a few weeks at least until the single pieces come from China!

Wolf-dawg…… I crown you—— Power Supply & Adapter Connector —- Finder & Tester Extraordinaire. :crown: ….
With the help of your willing & worthy assistant guass163 giving technical advice of course. :+1:

I just ordered one of THESE and two of THESE

I went for the free shipping, but I already have a tracking number for both…. so hopefully that is a good sign. :+1:

Thanks to you and everyone who helped in solving this mystery problem. :+1:

AFAIK You should be good to go as long as they send “Us” the right ones!! :+1:

The right angle ones are more beneficial for my use[mentioned in earlier post] and according to their time line and my calculations they will be here 10 to 26 days sooner than the Straight ones from China.

Straight ones I ordered first!

-Then I ordered a 10’ cable w/ the proper connectors from USA [Indiana]! That should be here Friday.

-Then the 90 degree angle ones! I think I will have plenty of adapters! :wink:

That is why I listened to my Cousin Settimio and got one. Only $3.50 more than my Supernight! :+1:

I was meant to have the Lite-on. :sunglasses:

The Hitachi was not meant to be. I said I wanted a brand NEW SMPS.Not a USED one like the Hitachi was.

However,along with a BLF members suggestion[can’t recall his name]and before my Cousin Settimio[Electrical engineer] convinced me, I emailed the Ebay Hitachi dealer to see if it was a 2.1mm connector:

Hitachi OEM Genuine 60W 12V 5A ADP-60WB AC Power Adapter Supply for LCD Monitor

New message from: usefulgadget Top Rated Seller(232,595RedShooting Star)

Sadly it is no longer available. We will be doing a sweep later to close these listings when we doublecheck the system for inventory count.

For this item, it was a 5.5mm outer by 2.1mm inner.

Best regards

No reason to get defensive.

All I said was I was meant to have the Lite-on. I did not want a used SMPS and the Hitachi eliminated itself by not being in stock anymore. :wink:

Here is a breakdown for the credit of my purchase:

Cousin Settimio-50%
Wolfdog-25.1%
G163-24.9%

Thanks everyone! :+1:

I just bought This to be able to use my Opus in the car.

^

Let us know how it works. I hope it serves you well. :wink:

Thanks for the replies!

I am aware of the voltage fluctuations. Nice to know the Opus is not too specific on input voltage. I will only connect it to the socket after engine start or after shutdown.
I had a car plugtip being fried once when running a 12volt coolbox while driving in the car on holiday. But I think it pulled more than 3amp. Could as well be due to a bad connection with high resistance and thus high temperature.

I’ll give it a shot and hopefully the fuse pops before the opus if things work out bad. In that case I guess I can place a new fuse and lower the Opus charging mAh and be fine.

So — can someone sum up?

Is the power supply currently (heh) provided with the Opus charger inadequate?

Assuming need to buy another power supply, how to identify models that are
— best (level 6) energy efficient and
— “green” (low power draw so not wasteful to leave plugged in)

The Eagle (USPS) is about to land…… :smiley:

Well, I just checked USPS Tracking and my package containing power supply from “speaker_joe” (ebay) is out for delivery to my humble abode. :+1:

I place the order about noon on 19 April & it should be in my mailbox about noon today, 21 April.

That is two (2) days from California to NW Alabama!!!
Talk about fast shipping…. speaker_joe must have had it out the door headed to me a couple of minutes after I placed the order.
Wow……… :slight_smile:

I actually think this may be only the second thing I have ever bought off ebay……… :open_mouth::wink:
But if I can find more guys like him it won’t be the last. :+1:

speaker_joe on ebay gets a 10 star out of a possible 5 star rating from me.
I would highly recommend him to anyone!!!

If you were to read this……. Thank You speaker_joe!!! :+1:

EDIT: This is just such cool, fast shipping I had to post the Tracking as evidence. :smiley:

I think the power supplies have been inconsistent. Mine was inadequate, so was Teachers,maybe others. What was established in this thread about 2 weeks ago is that Opus chose a DIFFERENT manufacturer for the SMPS in version 2.2 . If you go back several pages you will see that.

I can not answer the efficiency/green question. I am sure Gauss163 would have an answer/info. about that!

My set up is maybe a little different. I have a strip w/ 6 outlets and a switch to turn them on/off. I do not leave ALL of them plugged in because if I did, when I hit the switch they would all come on. I plug them in as I use them.

I hope this helped a little.

One suggestion. If you get an Opus just see what happens before you buy another SMPS. Again, in this thread[~2 weeks ago] I gave a detailed acount of when mine failed and what happened. It ALWAYS happen during the CHARGE/TEST just after transition from discharge to charge.

@ teacher

Let me know how it works w/out the adapter. Mine still works fine as long as I do not move it. I am waiting a few more days for the initial adapter!

My Opus BT-C3100 V2.2 works fine during the full Charge / Test cycle with the original 220V power supply. Tested it with 4 NCR18650 3400mAh and 4 30Qs at 1000mAh charge.

Maybe It’s already written, but does this problem only occur with the V2.1’s?

Yeah hank, Wolfdawg pretty much summed that up and about the need for a new power supply. Mine definitely need one.

As far as the other two questions about green & energy efficient, I have now idea…. gausse would probably be your man for that like Wdog said.
I also do not leave mine plugged in most of the time, it is either on a strip or unplugged when not in use.

Hope this helps……… :slight_smile:

@ wolfdog ………… I can’t do that, you never answered my PM!!! :smiley:
I wanted to see if you happened to know the two guys I spoke of…. :smiley:

I’ll check it out when I get home and get it out of the mailbox…… I’ll try to let you know later tonight. :+1:

Yeah I got a tracking number on the adapters but it will be a few days on them at the least.

But the power supply from speaker_joe got here lightening fast!!!
Thanks again for finding that, as well as the link to it. :slight_smile:

What is the brand name on your power supply??

No it is with the v2.2 mostly I think. That is what mine & wolfdog’s are.

Well I’m glad I brought this issue up a couple weeks ago with my unit. Looks like everything is solved now. I may get a new power supply eventually. But it doesn’t happen enough to really ve a problem at this point. Just occasionally.

Sorry for being late to this discussion… I may have missed this, but what is the brand/model number of the problematic power supply?

I have an Opus BT-C2400 (so not the 3100 discussed in this thread) that is v2.2, and came with power supply model KYT120100BV-09. Was just wondering if C3100/3400 v2.2 use the same one or different…

See post #150 and #152

  1. is My 2.2 SMPS POST #152 IS 2.1 SMPS which did not seem to have a problem. Opus CHANGED manufacturers of the SMPS which seems to be what caused the problem.

We would have to find someone who has the 3400 to determine that.

I have a 3400 —It was determined mine had the better PS—- the crazy think is I have a 3100 with the rounded corner crappy PS — when I was at the camp this week I did a charge/ test on some cells —worked perfectly

On another note—I went digging through my treasures (my wife says my junk)—I found two laptop PS —- 1 Liteon 12v 5.5a
and another IBM 14v 3.5a —-both barely heat up at all during testing
