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.
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.
So leaftye you’re all set then, getting a i4 replacement?
i’ll try to substitute it with nearly the same part if i got one since this is my main charger for my panny 
I4 V1 can’t handle longer cells
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.
Any authorized dealer?
