It is difficult to know, but at least the 12V DC is still working. Do you have a multimeter?

If it’s within warranty it might be worth contacting Nitecore.

It might be as simple as a fuse or it might be some part that is blown.

A internal fuse will usual not look like a normal fuse, but can often be recognized because there is a F (Maybe F1) on the circuit board near it.

Fuse is behind the yellow square, to the left of the blue square..

If you look real close at top left you can see "fus" for fuse?

Apparently these things were put together by people who have no clue how to solder...so check yours out well!

Check the solder points on the board for the figure 8 input, mine came lose over time when pluged in and out, it lifted the points from the board and bent the pins just enough away from the solder over time that it had no power one day when i plugged in, i just solderd them again and superglued the block down as the snapin hold down pins were lose causing it to lift when i pluged it in, my nephew has it now and hasn’t had any problems since i did the fix.

Looks like what is called a pigtail fuse best I can tell, cant see much in the pic.
https://www.google.com/#q=fuse+pigtail
It should have a voltage and current rating on the fuse some where. Find a match and solder it in.
I don’t know if its a fast blow fuse or not, but I would probably replace it with one even if it was not, if you could unsolder it and post up a few of pics of what you find, might help further locate the correct fuse.
I guess other fuses could be used in a pinch, you would just have to solder your own pigtails on to the fuse.

i4 V2 is brittle crap charger that overcharges AAA cells, there, I said it once again :D!

Both of my units never saw extensive or considerable use at all, they have been kept in good shape, however on one of them that Im using as spare-backup charger out in the country side the power cord has started to disintegrate near the tip of it where the in-charger tip is.

Piece

Of

Crap!

I had no idea that they soldered boards like this until I saw this on tv: http://youtu.be/3WRBMRyO4×0?t=39s . I thought they did it by hand.

This process has been used for many years, it is called "Wave soldering".

Try to pull the “hats” from the fuse, I guess it is a standard fuse with just two contact joints pressed on…

If you can't fix it, sell it to me.  I want one to make into a battery charging cradle for a hobby charger.

The low mode should be lower.

My I-4 v2 quit this week also. No power when 110v ac applied. I loaded it up with 4 Panny 18650’s every night for 6 months. One night it just stopped. Going back under warranty which is 18 months.

They wanted me to ship it back to them.  No offer for them to cover shipping.  Here's the shipping address they gave me.

Rm1407-08,Glorious Tower,850 East Dongfeng Road,Guangzhou,China 510600
Attn.: Lei Jun lai,
Phone: 86 20 83862000
 

 

 

If you change your mind, I'd love to take that dead charger off your hands.  All I really care about is the sliders.

Nightcore is in China? Sheez. This is revolting. Maybe I will tear it open. If I change my mind either way Leaftye, you can have it.

Did you purchase your i4 from a authorized dealer in the US? You should be able to return your i4 to them.

It makes it a huge hassle.  I don't fault them for being a chinese company or having their chargers made there, but at least have a return address in this country.  There are services that could handle it for them.  That's what Fasttech does.

Try contacting Nitecore yourself, but I fear you'll get the same disappointing answer I got.  If so, definitely tear it open.  You have nothing to lose.  Hopefully you can fix it, but if not, I'll be thankful for your charging cradle host.

Yeah, That’s the link I contacted them through three days ago. No reply yet. Purchased through Amazon in August 2013.

My first two responses from Nitecore took one day, and the third took three days.

 

When you purchased it through Amazon, was Amazon.com the seller or was Amazon only providing fulfillment?  Right now there are both types, and the primary vendor right now is Edison with Amazon providing fulfillment, but if you look at the right side you see that Amazon.com is also a vendor for a slightly higher price.

The low mode should be lower.

Yep, of course, I went for the lower price. Edison. sometimes saving a little $ is not the _best_way to go.

Edison Bright is a authorized Nitecore dealer in the US with full US warranty according to Amazon’s page

You'd be doing them a favor if you try handling the warranty claim outside of Amazon.  One of the guys from IS said an exchange for a vendor through Amazon costs them shipping back to Amazon, then back to the vendor, and they still have to pay for sending another unit to you.  If you handle it directly, I suspect they'll send another one out to you without requiring you to return it.  Or they might have Amazon ship you another one, again without requiring a return.  That's what Powergen did for me.  I contacted them directly, they asked for my order number, and they had Amazon send me a replacement.

Yes.  Illumination Supply came through for me.  Fortunately I bought it from them.  Ever since I've been buying more and more from domestic vendors that ship from within the US.

Well, mine still works on a 12vdc wall wart as well. That’s what I’ll do for now until they contact me. If they end up sending a new one, Leaftye this one is all yours.
