Thank you.AntonO.Very good charger.¹Steven P.Would buy again works perfectKen O.Just what I wanted. Anthony H.Good product and can charge different sizes Jana S.BEST CHARGER I HAVE PURCHASED SO FAR. LOVE THE 4 CHARGING BANKS.Joseph I.Works great with my 18650 cells, the 325 mAh charging speed with 4 batteries charging simultaneously is a little slow but overall I’m very happy!Paul O.This charger is awesome! Very easy to monitor charging progress. Flexible, charges every type of battery I use.Marilyn H.My grandson was excited to be able to recharge is New batterys for his remote thank you for making his birthday special and getting it to him so quickEliasGreat ValueWorks fast, detects battery type and charges automatically. Chose originally because I liked the appearance. Very fast shipping from 18650 Battery StoreKeith W.Works exactly as expectedDevice tells the user all of the relevant information and charges perfectly. I do not mind that it takes a bit longer than some other chargers to fully charge.JoeGreatGreat charger. I own a d2 and d4 and they are awesomeMarie CrawfordA bit disappointingOne of the receptacle doesn’t work. It’s a more complicated system than I expectedMarcus HayesLove it!Charger is excellent! I love being able to see the charge levels and type of battery and also life of battery.Jeffrey StormWorks wellThe nitecore D4 is well built and easy to use.Cory HamiltonGreat ServiceQuick shipping, well packaged. Will definitely order from here again.UnknownPerfect for meNot a rapid charger, but a thorough charger. And I have quite a few AA and AAA rechargables as well, even a couple of CR123 flashlights. In my mind, this was money well spent.BobGood Automatic ChargerJust put the compatible batteries in and the charger does the restDavid HumstonGood ChargerThis does not include 21700 on description but it fits 21700s. I use this for charging 30Ts and 40Ts all the time. It’s a tight fit but does NOT tear wraps. I’ve had the D4 for about a year and it still works well. The only negative is the spring for bay 1 is starting to get rough. It gets stuck when pushing it back with a battery so I hold it with my finger then put in the battery. I’ve been using bays 2+4 for 2x700s since this started a month ago. You cannot charge 4 2x700s at a time, but you can fit 2 in alternate bays.David BGreat chargerSuper fast shipping, great price. I would suggest perhaps a small piece of tape on the shipping bag. It was raining terribly the day it was delivered and the postman just left it on my uncovered porch. It wasn’t all wet, but water definitely leaked into the bag. Just a suggestion.ChrisWorks great, very intuitive interfaceNice 4-bay charger, very clear and easy to understand operation. Automatic battery ID is very helpful, made first time 18650 battery use less stressful.Terry OFirst time customer, completely satisfiedTruly satisfied with my purchase. Great price, fast shipping, and excellent communication throughout the ordering and delivery stage. I will be a repeat customer.CrisGood starter chargerCharger is good to start with, the feedback is nice. The only downside is the charging time. 0.375 A per cell (@4 cells, 0.75 A @2 cells) is really too low. But it is an excellent place to start, especially never having owned any 18650 cells to begin with.Joseph BarajasExcellent chargerThis thing works GREAT!!!!!PeteLove it!Great charger light year ahead of my first one. Now I can see what’s happening to each battery. It doesn’t get hot like my old either. id recommend itDashawn RichardsonDashawnGot 2 they work good I am good✌TedGreat ChargerThis makes charging my 18650 cells easy, very user friendly. Quick ShippingBryanWorks greatI couldn’t be happier. It does everything it says.
