Absolutely love the new charger and all seriousness. It’s very convenient. It works very well and I feel that my battery’s last a little bit longer with a better charge. My new Samsung batteries are fantastic.

Charger works great! I love how it charges multiple different rechargeable batteries. Great great informative screen. Charges batteries individually. Great for my lightsaber.
Charges batteries with no issues. I like being able to see the information as they charge and the auto stop is great.

I bought this to replace one that no longer worked. Had it for several years and use it all the time.
It's good

Great Batteries. Always a good buy!
Perfect
Very nice. Works as describe. Charging is fairly slow when using four batteries but not a problem, just leave it charging overnight. LCD with good indicators
My opinion, this is the only charger to buy.so easy to use and understand. You get features you would expect on something much more expensive. THE BEST
If you've invested in rechargeable batteries, it only makes sense to prolong their lives by taking best care of them. For *that*, you want a battery charger like *THIS*. Cheap, fast chargers are fine now & then, but to take care of your battery investment, you need a SMART charger. Nightcore D4 is a smart, dependable rig at an excellent price

Thanks IMR! Exactly what I was looking for...
This is the second one I've purchased in over 7 years, terrific charger, never let me down
No fast charging, but if you want to preserve the capacity over time it's best to no charge like a smartphone.
Great charger! Very reliable, with the automatic shut-off to protect against over charging.. And IMR ships quickly. So this purchase was a win-win. Thanks guys!!!
Fast shipping, great product
Awesome charger love it. IMR is awesome. Fast shipping and great prices!
Awesome charger! Doesn't tear up battery wraps and works very well.
Great price, fast shipping, easy check out. IMR, is the go to place for all your battery need. Never been let down.
Great little upgrade from the previous Nitecore battery charger I was using. I love the display and the information is surprisingly useful. Feels like good quality in the hand I expect it to last quite a long time.
Nice
Use this to recharge my Sanyo NCR18650GA 3450mAh flashlight batteries with PBT- works very well! Simple to use, gives useful info on battery charging status.
I have been asked for a review but know little--however, the charger was easy to use and appeared to do exactly what it promised to do in all respects. It is clearly a sophisticated charger that, to a novice, appears to work perfectly.
Using rechargeable batteries, like me, you probably have a small hoard of chargers. Don't use the freebies, please! I began learning about battery safety more than ten years back, learning first and foremost that your charger, or the safety/reliability of your charger is highest priority for your family & household, period! Nitecore is a top name you can depend on for safety. Experts agree & sent me to this brand more than a decade ago.Provided you simply use the charger for whats its designed for, rest assured you’ve made best choice for home battery safety. The D4 has plenty of smarts & versatility. I prefer it over other Nitecore models. Im about to pick up a replacement only because my first one is now years old with tens of thousands of hours w/safe reliable daily use. Yes it can warm up, but never dangerously, its a slight warming. If that concerns you, go with another Nitecore model (not maker). Nitecore i4 stays cool (I use one also) I just prefer D4. Upgrading to a new replacement of exact same item is a five star rating, also a Thank You to Nitecore for keeping our household in freshly charged batteries every day of the year, for years.
it's okay but it does get hot
Great charger, love the auto-shutoff feature.
This is my 2nd of these. Works great.
Great charger. Easy to use.
Works wonderful no issues
Great charger and competitively priced!!
Quality charger for my 21700s (30T Samsungs) and all of my 18650s! I switched from a Luc 4 v2 when I discovered the fit for my 30Ts were a bit too tight, and after reading the review from Battery Mooch knew that this one would be a great addition to my kit. I now have one at home and one at my office that I share with co-workers.
