I did however find the origin of your original fan wolfdog, shown below (unless I screwed up.. Facepalm )
I got curious as to the ADDA label on it. The green label says “Made in China”, but it appears ADDA has a USA Headquarters in Orange, California

ADDA Fans .. If you click on this link you will see your “original” 5V fan (#AD0205MX-K50(TX) ..) listed. Just under it is the 12V model. The dimensions of these are 25 × 25 × 6 mm… it seems as if I remember the “original” being 25 × 25 × 9 mm?? Who knows??? Shocked

AD2506 Series .. Just another charts that shows dimensions & specs.

And as far as this fan below goes (this is one of the ‘replacements’ I got from GearBest) ….
……I found the company web site ( qfydz ) , but have not been able to find the fan listed. Imagine that…. Facepalm

GearBest replacement fan I ordered

.
My goal in this was to try and find one that did not have to be modified to fit. A drop in replacement so to speak with the same or better specs than original.

It appears the ADDA has the same cfm as the Delta but it is only 6 mm thick.

And I could find no data at all on the “qfydz”……

EDIT: I just emailed “qfydz” and asked for the specs of the mystery fan. Time will tell if they answer. Wink

My delta fans specs. from speaker_joe’s Ebay add.

Specification
Nominal voltage : 12 V
Current : 0.12 A
Operating voltage range : 4 – 12 V
Fan speed : 13,000 RPM
Performance : 2.4 CFM
Noise : 28 dBa
Size : 25 × 25 × 10 mm without heatsink

I wonder If the ADDA 25mm x 25mm x 09mm has the same specs as the one you posted 25mm x 25mm x 06mm? My guess would be yes.

Nominal Voltage: 5V
Current:0.65A
Fan speed:12,000 RPM
Performance:2.4 CFM[Ability to move air]
Noise: 29 dBa [decibels]
Size: 25mm x 25mm x 06mm 25mm x 25mm x 06mm???

The Delta’s numbers and the ADDA’s numbers seem comparable.

All I can tell you was the amount of air dispersed by the Delta fan was very noticeably superior and higher than the ADDA fan.

I would venture to guess close to or twice as much. Another guess, maybe the fan blade is superior on the Delta?

Dale got my fans today. I can’t wait to put that fan back in there! In the future if I need anymore, we have speaker_joe right here in the States. Thumbs Up

Email looks good to me, I’d still like the charger to be in the $40 range though not $50 just my opinion should be able to upgrade the PS and fan and keep the price the same. Buying thousands of pieces at a time. Should only cost maybe a few cents more per unit. As we the consumer buy 1,2 pieces as needed PSU/fans

Edit
If the price should go up 10-15$ I’d want more features. Like a 2 amp discharge like the sky rc 3000 they make. A 2 amp discharge would ve great. More realistic what we see in flashlights. That’s why I dontbhave a lii 500 yet. Its better then nothing but 500mah discharge isn’t very good to me. I have laptop pulls that are 1900+mah. But when ran at 3.5+ amps the low voltage starts to flash and upon recharge only discharged 350-400ish mah. Using it at lower modes/nightlight duty works fine. But a higher discharge rate would let us see some voltage sage in relation to this hobby more then 1 amp and without having to invest in a traditional hobby charger

Thanks for your comments and your input regarding improvements. Wink
I too think your email looks fine Robert. It seems you covered everything well.

I somewhat do agree with Speed4goal. To leave the 3100 as is and to fix the power supply supply & cooling problem should add little to no increase in price as far as I am concerned. And it needs to be BETTER than just the bare minimum to get by.

Now if they want to up the discharge to 1.5A or even better to 2.0A that would work for me & I’d pay a bit more gladly. BUT, if they do this they need to have the power supply and cooling figured out from the start.

IMO it needs to be better than just “barely enough to get by” (so as to save a few cents) … It needs to be overkill or close to it, so as to handle any situation without a problem: both power supply & cooling.

None of us are buying these things to have to figure out what is wrong with them and then patch them up. It is a huge waste of “our” time & money.

That is my .02, which in the big scheme of things is worth nothing. But there it is anyway. Smile

PS… even though mine has not done this “yet” on the heat shut down. MAYBE it is just because I have not been testing any high IR batteries. I don’t know??? Just a thought. Smile

Hi, Robert.

we have an improved version power supply. The label is marked with extra printing to tell the difference between old one and new one:

NEW ONE!

We have no:17[17 means 2017] used.While the old power adapter don’t have this year code info.

year code info.

Concerning fan, this can be a problem.

We can source really good fan, but the price is $5.0 more comparing to the current fan we are using. If you are willing to pay extra $5.0 for this, we can purchase this fan to be used if you are going to order.

We are testing the new power adapter and to make sure we are not having this problem.

Also we are working on a new design, that will get rid of this high current pulse completely. The new design is being revieved technically and once we have sorted out all the problem, we will make a new design.

regards

henry

Hi Henry,

There is NO difference whatsoever with your new power supply except the Number 17 written in the bottom right corner! ALL the specs are exactly the same!

I already used my own money to buy the fan and the power supply. I was making these suggestions for future customers and possible purchases.

This is a picture of my FAILED POWER SUPPLY! Looks just like your supposed improved one, minus the #17 in bottom right corner. “rdana” will not be happy either.

Sincerely, Robert

Well, is a power supply honestly meeting those specs going to be adequate?
Could be they got cheated on the first batch of power supplies and they weren’t up to spec.
Someone like Gauss could comment on the spec (probably already has somewhere above)

Aren’t you glad we’re not buying anything life-critical from China?

Hey, did you know China has been building a new, economical fission power plant design?
So safe they don’t waste money putting a containment building around it ….

Love the quote! I should have known better! How stupid does he think we are w/ that phony power supply picture and him saying that,

“The label is marked with extra printing to tell the difference between old one and new one”

lol!!! yaa,, the number 17 is written on it w/ the exact same specs!

@wolfdog ….. Well, you gave it your best shot with the email. It appears ole’ H. Xu thinks we all fell off the turnip truck yesterday. (That would be an old Southern saying meaning…. he seems to think we are all a bunch of dumb a$$e$)
Oh well, you tried. Thumbs Up
Maybe LiitoKala will beef up the Lii 500 just a bit with a 1A discharge & maybe add a fan. Call it a Lii 550-Plus.
Then we can just boycott OPUS & never buy another one. Which, come to think about it; after all this BS: there is no danger of me ever buying another one anyway. Wink

Now, moving on. You wrote the below & posted it at the exact same time I posted THIS .
Yet you have made no comment/opinion/input of my post referencing your email to Henry Xu. What are you waiting on? . Big Smile

I thought it best NOT to make a comment! Since you asked. This is what it would have been,,,,you had to go by my post to make several of your posts.

Would have thought most likely you would have seen and read it! Silly

Darn, I should have known better than to even ask…. Facepalm
Try to pay you a compliment about your original emai to H Xu & you can’t handle it. Silly

Actually, after telling you your email looked just fine & that you seemed to have covered everything well….. Most of what “I” said was agreeing with (as I noted) or expounding upon what Speed4goal had said.

With the exception of course being the part about having to spend money to fix it. (all quoted below of course… Thumbs Up )

Reading comprehension….. Priceless!!! Big Smile

You know what fellas—this charger isn’t worth all this —-it’s just a charger is all—it has limits/flaws like everything else we purchase—we all know how this stuff is manufactured —- CHEAP—- somethings can be fixed—some can’t

So … so … instead of improving the power supply, they’re trying to eliminate the current draw pulse that overwhelms the power supply.

Maybe.

And in the meanwhile, they’ve told the power supply builder to quit using chewing gum in place of good capacitors, or something?
(since it’s the identical model, identical spec, but the label changed “plus 17 on the corner”)

I can see a meme possible here for reviewers:

“We found this to be a mediocre product, the manufacturer should put 17 on the corner to improve it …. “

This should have been revealed in the FIRST email!

6:52 AM (3 hours ago)

to me
Hi, Robert.

The power supply has its internal design changed completely. we have minimum over current protection from previous 6A to 7A, and its output power capability is also higher.

we are making more testing to confirm this.

What kind of power you are expecting us to use? can you make any suggestion? you mean with 12v 5A rate power supply?

regards

henry

Hi Henry,

Why didn’t you provide that information[specs] in the first email? If your promoting a new design it would be nice to provide pertinent information instead of being vague!

In regards to the power supply.

-The one provided for my charger[KYT120300BV] was inadequate and failed as described in my initial email.

- The one I bought myself is very high quality[LITE-ON 12V/5.5A/66W]

-Your NEW design is yet to be used and proven sufficient.

To further answer your question: Whether it is 3a/4a/5a ect. It NEEDS to the job. That is your companies responsibility.

I hope it works well for the people who buy the charger. For me and a few others it is irrelevant because we have already used our own money for replacements.

None of us are buying these things to have to figure out what is wrong with them and then patch them up.

So what are the specs of this new fan that will be an additional $5 and who is the manufacturer?

Cheers,,,,,,,,,,,,Robert [Wolfdog1226]

Hank,

I hope your not mad at me for borrowing the quote. Smile “None of us are buying these things to have to figure out what is wrong with them and then patch them up”.

It was a perfect quote to use in my rebuttal!

I have been writing poems and quotes for a long time. I enjoy philosophical, meaningful, simple and direct communication,,,especially when it is written.

I will share this with you. I wrote this yesterday morning before the suicide bomber in Manchester UK struck.

To me it is eerie, to others it may be a coincidence.

Well said wolfdog!!! Thumbs Up I agree also, that was the “perfect quote to use in your rebuttal!”

I also have a suspicion that hank is in no way “mad” that you used it. He is a team player as most all of us are. Thumbs Up Personally, I am estatic you found the quote, taken from post #678; so useful in your rebuttal. It definitely had a ring of honesty & truth to it!!! Thumbs Up

Oh yeah, I’m not mad that you used it either….. I am, as previously stated; most pleased you found it useful. Smile

Worth emphasis: the labels on these wall-wart SMPS aren’t large enough to include all of the pertinent specifications.

One shouldn’t be so quick to (mis)judge Henry’s replies if one has little experience with such matters. Keep in mind that – with Opus – we are lucky to have engineers who are willing to communicate directly with customers (which is often a painstaking task for an engineer). It is important to be polite when communicating with them lest they revert to the industry norm and funnel everything through clueless CSRs and useless boilerplate replies. Also keep in mind that language differences may complicate communications (e.g. replies may be more terse than desired due to difficulties writing in a foreign language).

I think it is time to pass the torch. Why don’t you take over now? Then again, there is really nothing left for him to tell us! Whoever buys the new Opus package can report its successes or failures.

I have done a lot of thinking the last hour. It is time for me to focus on finding a job instead of spending valuable time trying to get answers for something[Opus Charger] that at this point is irrelevant to me. There is no need for me to get frustrated anymore.

Hmmmmmn, well said gauss. Thumbs Up Kinda nailed me right between the eyes, Facepalm
I have been somewhat critical of Mr Xu. And basically, he has forgotten more than I know. Shocked

Mr. Xu, should by some miracle you read this; my apologies for any criticism I aimed in your direction. You have been responsive to Mr. Robert’s emails and that at least says you are listening. Thank you!!! SmileThumbs Up .. And thank you for providing the information you have thus far. Smile
~~~~~~~~~~~~~~~~~~~
@ gauss….
I do understand what you are saying about the labels gauss, but IMO… Considering all that has gone on about the power supply, it would have been nice had the information been received in the first response to Robert (wolfdog). Though I do realized, due to the things you mentioned such as language barrier, etc., etc.; That is something that certainly cannot be expected. For example, if I had to correspond with him (or anyone else) and answer questions in Chinese…… we would all be in a world of hurt. Big Smile

Awww, come on Robert, don’t throw in the towel completely; just choose your battles. Smile
You have found out a ton of information and in finding the “good information” you have dispelled about 2 tons of what turned out to be “wrong info”.
Yeah, I understand about the time involved. I have put a lot of hours reading, researching, and mostly trying to keep up with this. BUT…. I have only a small fraction of the hours in it that you do. You have spearheaded this. (And make no mistake, I am serious when I say that!!!!! Beer )

So yeah, do what you have to do about finding work. (heck, check w/ Liion Wholesale… that might be a perfect fit for now Question ) ; but don’t give up on this. You, and to a much lesser degree “we” almost have this whipped. And now it is basically just the principle of the thing to see it through. Smile

And besides finding out all this info, you have somewhat brought us together as “Family”. Thumbs Up

I mean look, (and you first mentioned this many posts & pages back) ; you and gauss are actually talking & communicating without actually biting each others heads off most of the time. That in itself is a tremendous accomplishment!!!!! Thumbs Up

We have rallied around a cause here on BLF…. “The Friendly Forum” and by durn we have almost become friendly.

  • You have “almost learned” when and where to use !!!!! marks. Almost being the ‘key’ word there, but you are doing so much better….. Wink
  • Even though you have become “frustrated” at times with the situation & others and possibly said a couple of things in haste….. you have always so far bounced back with renewed vigor & pressed on.
  • You still have a bit to go to know when I am “pulling your chain”… (this IS NOT one of those times either) … but you’ll get there. Smile

All this is said in a somewhat comical manner, BUT I am serious about it all Robert. Smile
Do what you have to do, relax & don’t get frustrated over this. (as our friend ‘chops’ said… it is only a charger) ; but see it through as your time allows. Smile

No problem at all hank. As it was, it gave Robert a the perfect chance to give me a compliment on something I wrote. Wink

This whole thread has been something else to watch unfold.

But at least it seems like they play to release a 2.3 version. As long as it discharges down to 2.8 to keep it fairly accurate and it all works I’d get another. And one day in the future plan to even if its the one now. For the most part mine worked 85% of the time as intended. And for $30 investment has given me my moneys worth in a charger. Even though mine charges a little low its the only charger I have that charges to the exact voltage on all 4 slots. Someone mentioned a fix but I’m not comfortable soldering on the board. As $30 for another charger isn’t in the budget right now. Its close enough for me.

In the end it seems like something good will come out of it. It seems like they listened and will make a new revision eventually and phase this one out. Like the 2.0, and 2.1 versions.

^^^^^^^^^

I guess time will tell what they do Speed4goal. I agree with you pretty much. Keep the discharge to 2.8V, address the power supply issue fully, do whatever they can with the heat issue, and it would be nice if cell all came off the charger at right at 4.2V.
We will see…………… Smile

I decided to cut the raised vent slats out of the bottom of my 3100—The way the vent slats are made I was only able to cut out every other one(this way left more to support the remaining ones—I feel this is a big improvement in air circulation— The air coming out the fan is 2-3 times more evident(hope that word makes sense) I’m discharge/charge testing right now—if some one wants a pic let me know
Today I also tore apart a broke laptop for the blower/fan— thought it would be perfect for the underside of the case—worked spectacular on a 4.2 cell— it jumped once with 12v Dead now—it was 5V but on many post it was stated 5V will run on 12V just diminishes the life—I didn’t think it would be so quick—LOL

Hmmm, sounds like a good idea chops….. Thumbs Up

Yes sir, I’d like to see pics please. Good ones too…. Big Smile .. I’ll probably just do mine like you did yours. Smile

Sounds like you have a good idea with the other fan too……. sorry it was so short lived…… Wink

I honestly do not know.
I searched and all I can find is what it said below the video when seen on YouTube (copied-pasted-translated below)….. “the voice of Celtic woman”.

It sure is a sweet & relaxing voice though. Thumbs Up .. Wink

Here’s my 3100 Back with every other slat removed—I used a cut off wheel with a dremel —- air circulation with positive end of the charger raised is 2-3 times better

Did you take the back off to cut it??
