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

^
:+1: … Excellent. :slight_smile:

I am glad I have two SMPS. The second one arrived today. I was planning on having that one as my back up because the SUPERNIGHT works Super!It is definitely my back up now!

This back up is getting its first test now. It just passed the transition from Discharge to Charge. I thought it was going to reset numerous times and it is still demonstrating that behavior even at the 3.40v mark!

After transition I hear a slight power loss and then it is restored. It has been doing that every 30 seconds[I timed it!] for 15 minutes! The SUPERNIGHT never did that.

Imagine someone revving up an engine very slowly and then releasing very slowly and then doing the same thing. That is the only description I can think of.Basically the fan noise weakens because the power is weakening. It is also WARMER now than the SUPERNIGHT was @ 4.1v which was the peak of heat intensity. We are only at 3.48v!

Hopefully the SUPERNIGHT will last! I would not trust this back up for long!

Good info…… What is the brand name of it… so as to avoid?

I agree………my first thought is that its NOT 12v/5a,or defective.

The thing only cost $7.38! It is still money,I will email dealer and go from there. I hope it is NOT more aggravation than what it is worth.

It is FALVOCANO,No mention of the name on the unit but that is what the advertisement says.

I contacted then,hopefully things go smooth!

This is the one,stay away from it!! The envelope is still warm and it put it in there 10 minutes ago!

How about a 12v/6a? or 12v/8a down the road?

If I got one of those it would most assuredly have enough power even if it did not meet specs.

Technically, I do not even need a back up because the ONLY time the original SMPS W/ the Opus failed was when it was ~ 2.8v/2.9v when it transitioned.

It charged 4 X 18650 w/ no problem when they go in as usual,3.6/3.7v. I have no more batteries to test and do not need any for awhile!

Can a 12v/8a/10a SMPS hurt my charger? My guess is no, it will just have more power and room for cooling?

How do I know that these are better quality? How do I know how long they have been used and the duration of use per day? Don’t they sell those kind new?

Thanks,Dr. Capolini,“King of questions and analyzer to perfection”!

When I buy a car[used] i can see the condition it is in and how many miles are on it!

You leave my SUPERNIGHT alone!! It is top of the line primo quality!You recommended it , right??? That is right, you did not know I was going to get it!No justifying Gausse,bottom line you recommended it!!! :stuck_out_tongue: So PIPE DOWN once and for all!!

,HAPPY EASTER,Capolini,Qui Riposa in pace

ok,maybe I will use that as a main one and my SUPERNIGHT as a backup!!

How come these used ones never tell what size the barrel connectors are?

ok,so where is the NEW ones?!! This is another used one!

Last comment on Supernight!

I never said you claimed that it was high quality. I am saying that you recommended it and have badgered it several times since! You want me to open it up because it may be shabby. Shortly after you recommended it you posted others for Teacher that are supposedly better!

Supernight is doing fine ,does not get hot and has gotten the job done so far!

….It is way past my bed time,I get up at 5 every day to take the BOSS out!

I am IMPRESSED!!! I got a refund already for the SMPS that did not work right!!! I guess they do not want the piece of crap back!

I saw some reviews on it and a guy said it could not deliver more than 1 amp!

ok,I found a “supposed” new one on Amazon for $6.99,has to be a fake!

What do you think?

https://www.amazon.com/UpBright®-Adapter-HITACHI-ADP-60WB-Monitor/dp/B0140C7VAA

I emailed the Ebay Hitachi seller to find out what size the barrel connector is. I want it to be 2.1mm NOT 2.5mm even if the latter fits, I am sure it would be losse.

It is listed for .99 cents!!! I guess that is an error!

The barrel connector is the 2.5mm NOT the 2.1mm.

Do they sell an adapter/converter piece to attach to the 2.5mm and converts to 2.1mm? I would think the 2.5mm would be loose and I do not want that.

EDIT:Yes they do Wolfdog!! Lets NOT complicate this!! Less than $3 on amazon. Keep it simple Wolfdog,just get one w/ a 2.1mm!!

How about this brand NEW Hitachi…only $41.79!!! More than I paid for my opus! Its connector is the 2.5mm…….I would assume the Ebay one is the same. :person_facepalming:

Ok,thanks,

Yes they do sell adapters Wolfdog!! Lets NOT complicate this!! Less than $3 on amazon. Keep it simple Wolfdog,just get one w/ a 2.1mm!!

@ Gausse163

I need you to verify this Dr. Gausse!! I may change my mind again if you believe this is a winning combo!!!

If I get THIS:

I want to make sure it will work in this recommendation of yours!:

I already have 2 power cords. SUPERINGHT and the faulty SMPS one where they do not want it back,I guess shipping a faulty piece of junk would be more of a loss for them. No complaints,free power cord and reimbursed in 3 hours!

OK,Thanks,glad I asked. It is confusing because when I saw 5.5mm/2.5mm to 5.5mm to 2.1mm I thought it was right. the female/male part was what Screwed[!] me up!

Is Lite-on as good as Hitachi? I am glad the lite on is new.

Thanks Gausse,Your intelligence is comparable to My Friend Dr. Eissler whose mom was from Germany!!,still a step behind from my 1/8 German and Italian people!!!

Ok Gausse!!!

I pulled the trigger on Both of them! I have my SUPERNIGHT to guide me through the night until they arrive!!

I found one place,can not remember the name is was ~ $19 for 2 including shipping! :money_mouth_face:

Or you may try this: I have experimented with these years ago on my Opus. (for a more stable but overkill 12VDC)
