I want one as well. Any news through the grape vine?
These guys will sell you a pre-order…
I just ordered the D2 from Battery Junction :-). Will probably pick up the D4, next pay period. Can’t wait to get it!

you shoul use the email link: http://www.banggood.com/NITECORE-Digicharger-D4-LCD-Display-Universal-Smart-Charger-p-928155.html?utm_design=13&utm_source=emarsys&utm_medium=mail_men87_email&utm_campaign=newsletter-emarsys&utm_content=xuxu&emst=9GHLaXUo6c_189051_973592_11
Yes you are right. thanks.
D4 seems interesting now since it accepts lifepo also. Might be a good reason to buy one, if it charges properly. Anyone a word about it yet? 
I use the crap out of my i4, so even if this is only slightly better I’ll probably buy it. Even if the sliders are smoother and can safely charge 10440’s that’s enough for me.
That is the usability view point. I am interested in the electronics, I wouldn’t like to buy a crap. Most of chargers around that have the same look were crappy in the first revision and became better a while later. I can live with crappy sliders if this chargers li-ion/-po/-fe and ni-mh a proper way they should be charged
Did the price at banggood go back up to 39.95?
It only chargers NiMH, not LiIon.
Nitecore handles both.
They've been raising prices of other items too.
i had opened a D4 thread too. my nitcore i4 served me really well, i don't use it anymore because i am interested in this upgrade!!
:D
If anyone is interested it’s 32.5 here http://www.aliexpress.com/item/1pc-2014-New-Nitecore-D4-Digicharger-LCD-Display-Battery-Charger-Universal-Nitecore-Charger-Retail-Package-with/1914701653.html
Looks like a reputable source, I’ve never dealt with these guys but they do have a good rating.
I’ve dealt with em before, and will again. Might get one of these soon, sick of the sticky sliders on my i4
The Nitecore i4 was (is) my first 18650 charger, I am waiting for D4 reviews to decide if I will upgrade.
It looks like an Acucell 6 clone?
That's only a little less than from Hobby King, and I'd trust Hobby King a lot more when they say their hobby charger is genuine since they cater to a group of hobbyists that can easily call them out for carrying fakes.
Also, there's open source firmware that allows this charger to read internal resistance and output data to a computer using Logview, and because of that I'd really want to make sure I get the real thing. Hopefully next week I'll be able to post about how to do the firmware update and how well it works...or doesn't.
