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

@gauss163

^ No, that’s the wrong conversion - enlarging the hole (which is far more commonly needed since you can’t plug a fat center pin into a skinny hole). Instead you need to shrink the hole. So the adapter’s center pin should be a fat 2.5mm, and it’s opposite hole should be a skinny 2.1mm. Often there is confusion about which connector is male and which is female, so you need to be careful. This listing makes it clear that it is the correct choice.

There’s a good chance you won’t need an adapter. Even if you don’t these common DC connector converters are useful to have around since eventually you may need one (both directions are useful, i.e shrinking and enlarging the hole).

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!!!

LITEON is a top-tier SMPS manufacturer, the OEM for many laptop SMPS (e.g. Dell), etc. The Hitachi is made by Delta, which is also top-tier. The Delta is probably older than the LITEON, but I can’t be sure since I see no markings that reveal its age.

If you bought either from DigiKey or Mouser they’d probably cost $40 or more shipped.

The Lite on is brand new.

Why? As I said, there’s a good chance you won’t need it, and you can always use the SuperNight till then. You can probably find the 2.5 to 2.1 connector adapter in USA (if not on eBay then try DigiKey or Mouser).

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)

Got my LITE-ON SMPS Today. 12V/5.5A/66W. Works like a charm……not even close to warm. :+1: Supernight demoted to back up.

Thank you Settimio for recommending it. Qui Riposa in Pace.

Nice!! Can you put a link to where you got it Wolfdog please.
Was the barrel plug the right size or did you get an adapter?
Thanks for your research & testing on this.

[wolfdog1226]

Sorry,can not provide the info,u never answered my email!!! :smiling_imp:

I do not have the adapters yet. However, it fits fine,you can barely tell it is slightly bigger. Adapter really is not needed but since I ordered a few I will probably us them. Mr. Opus is happy.

Settimio told me about it. $10.45 ,3 days from Calif. to Suburban Philly. :+1:

My guess is that you would need to have an account to order from them, I do not know for sure.

If you decide to get barrel connector adapters I would recommend the ones below.

They are at a right angle which saves me room because my Fenix ARE-C2 is right in front of the Opus.

Plus its arrival date is anywhere b/w 10 and 26 days earlier than the first Two I got which are straight. I could get mine next week. These are coming from China like the first two I ordered.

Keep in mind, Wolfdog1226/Capolini and others that the Inside temp. was:

EDIT: It is 84F outside and 77F in my condo. The SUPERNIGHT MAX TEMP. was 94F.

The indoor temp for yesterdays initial test was 67F and today is 66F. The Lite-on has the pleasure of being in 10 and 11 degree cooler testing environment.

With that said, I doubt if the Lite-on would reach 94F under the same circumstances as the Supernight in 77F degree flashlight laboratory temperatures!

My 4 X 18650 Orbtronics are at 3.70V now,charging after the discharge test. The external temp. of the Lite-on is 68F. The peak temp is ~ 4.10v .I will re check it then.

ALL in all this is not a fair test until Flashlight laboratory is the same temp. for the Lite-on! It does give an indication that Lite-on is working well and not under stress! :sunglasses:

[wolfdog1226]

Since the room temperatures have been different. This is the Only comparison I can give.

Test: SMPS Max external Temperature when charging 4 X 18650 3400mah

Starting Voltage: 2.80v immediately after Discharge/Test
Ending Voltage: 4.20V

Participants: Supernight 12V/5A/60W…….Lite-on 12V/5.5A/66W

Supernight
Indoor temperature- 77F/25C
Max external temp.–94F/34C
Difference:17F/9C

Lite-on
Indoor temperature:66F/19C
Max external temp.–69F/20C
Difference:3F/1C

When The temperature reaches 77F/25C in my condo I will do another test w/ the Lite-on. MY guess is that its external temperature will not exceed 84F/29C. :sunglasses:

Photos of the S’night 2.1mm Barrel Connector and the Lite-on 2.5mm Barrel connectors.

The holes themselves seem identical in SIZE. The smaller S’night 2.1mm seems to use a spring loaded pin/clip, almost like a flexible cotter pin to reduce the size.

Supernight 2.1mm

Lite-on 2.5mm-Angle shot I turned this around in Post image,it will Not display that way on here???

Lite-on on TOP-Sorry for the blurry picture.

Side by side. Lite-on is on top. It has a shorter :exposed” barrel.

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. ….
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:

[wolfdog1226]

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!

http://www.ebay.com/itm/142340377628

-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!

[wolfdog1226]

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

[wolfdog1226]

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

[wolfdog1226]

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.

Here is a breakdown for the credit of my purchase:

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

Thanks everyone! :+1:
