Xtar VC4 v Nitecore D4 - Charger Review and Test

VC4 Amazon USA - amzn.to/39FKkKU UK - amzn.to/39SVtZb D4 USA - amzn.to/2wOsXsG UK - amzn.to/33aiO63

[@leighhaynes]

I ordered the newer D4 EU model (2016) from Amazon UK (supplied by Amazon) but they sent the older D4 (2014 non-EU). Is it worth trying them again or should I use another seller?

[@MrBazReviews]

Hi Leigh was it from Amazon directly or fulfilled by Amazon? I'm not exactly sure what the changes are with the EU version if any over the previous one.

[@leighhaynes]

It was Amazon direct. I paid slightly more as I thought direct would be a safer bet. I am also not sure if there are any real differences or if it is just cosmetic to distance themselves from the clones. Was your EU edition from Amazon direct? Great review by the way. On balance, I prefer the Nitecore for the extra battery support, clearer display and mains power connection. Just a shame it doesn't have the charge rate and LED indicators of the Xtar. How would you score these two? Would be interesting to know how you rank them vs the other chargers you have reviewed.

[@leighhaynes]

I emailed Nitecore about D4 vs D4 EU. They said there are no differences, it is just different packaging for a different production run.

[@MrBazReviews]

Fair enough thanks for letting me know

[@iqbalviali]

thank you for put the resume of the test in the end of video

[@peterharle]

I have both chargers, the D4 slider guides internally are very flimsy and had cracked after changing cells several times a week. Disappointing, had to repair with hot glue to fix. Worked fine otherwise, for around the same price the D4 has an internal supply while the VC4 requires an external source.

[@Vysair]

@@mikestudmuffin4549 also for safety as well. Having it internally is really just another point of failure and a variable

[@Vector_Ze]

There are at least six typo's on the back of the Nitecore package. Sorry, the natural proofreader in me, can't help it, LOL. Thank you for the reviews! I'm in the market for a new charger.

[@MrBazReviews]

Well spotted yes a common problem on some China goods, though they are improving just have to hire English speaking people that's all ;-) Some makers just don't want to spend the money! Despite that it's a good charger in most ways I like the design and performance.

[@hceggeberth]

"....six typo's"? Don't you mean six typos? No apostrophe is required before the suffixed 's' that indicates the plural. As a natural proofreader you should know this. I hope you're enjoying your new charger ; )

[@mrawesome6239]

I have both, vc4 is a major win.

[@MrBazReviews]

Yes in some ways it is the better charger (faster speeds, genuine 4 channel not split), D4 is still quite a solid choice for some users lower charge for smaller Li-ion cells I'd like to see a new VC4 with a few extra choices on charging speed

[@MrBazReviews]

Thanks Jason I just tried to show what might be important for viewers so you can make up your own mind which charger might suit best. Appreciate the comment more charger reviews coming!

[@Lex10999]

I have the Nitecore D4, just like in this video. I also have the older Nitecore Intellicharger I4. In the newer Nitecore D4, If I charge an 18650 to full charge, remove it and replace it back in again, it continues to charge more. so it will not charge to 4.2 volts. On my older Nitecore I4, I charge to full and take it out and replace it again it will not charge anymore. If I then put it into the Nitecore D4, it says 4.2 volts and will not charge anymore either. My conclusion is the older I4 does charge batteries to the full 4.2 volts where the D4 doesn't charge batteries to their full 4.2 capacity. Did you test the batteries in the D4 to see if they actually reached the full 4.2 volts or was it less on your unit?

[@kosztaz87]

If that's true, then the new charger is a lot better. Battery lifetime drastically improve if you don't charge them to 4.2 volt. I wish there was a charger, where you could actually set the voltage threshold. so it wouldn't charge the cells above 4.1 volt.

[@marvelydecena4941]

I've also experienced that to. When the AA batteries is fully charged in nitecore D4, I remove and replace it again but still charging. Is that an issue ?

[@mshelton99]

zoltan87 There are chargers that the user can set the terminating voltage, but you have to move to hobby grade chargers designed for the RC Hobby. Charger cost also goes up along with the need to actually set the charger for each type of battery and the charge rate. Look at iCharger and Powerlab chargers as well as ISDT chargers. Look up ProgressiveRC to find all of these. Like I said be aware that you won't find these type chargers for the low prices of the Nitecore and Xtar plug and play chargers. Also, the hobby grade chargers can discharge the batteries and monitor the mah taken out so you can find the actual capacity of any cell. I use and love the Nitecore D4 for 18650's, but I wouldn't trade my hobby chargers for anything. Plus I charge large high capacity Lipo cell regularly so they re a requirement.

[@Richard_H]

I have had a Nitecore D4 running(24-7) non stop for the past 2 years, i have been using it nearly exclusively to charge some high end 18650's. Now my d4 died like 10 days ago and i will get a new one and will be getting a new Efest Luc Blu6 Oled. Now this is my personal opinion the Nitecore D4 is one of the best all round charger out there now a days, oh and remember its not because you can charge AA and AAA bats on this type of charger that it means its a good idea to do it.

[@MrBazReviews]

Interesting stress test! I suspect new models are due from both makers next year though I find the D4 to charge better than their newer i series chargers I hope Nitecore do a better job on a new D4 than their other models both the new i2 and i4 tend to undercharge a bit particularly NiMH cells.. I'll try to get some 2 bay Xtar chargers to test too. Due to the lower charge output the D4 is probably a better bet if you regularly use AAA or AA cells. Would be nice to have a 0.5 amp across the 4 as an option. The VC4 has the advantage there if it's a factor.

[@Northisbest]

Hey I have D4 for about 1 year...but I'm gonna get VC4 mainly for USB fun and I will still use both...I have have crazy many torch and USB fan with 18650 battery. 18650 batteries are really popular now 🤗

[@panda909TV]

For 18650 with 3,600mah ....what charger do you use sir ?

[@ask8900]

so VC4 or D4 ?

[@MrBazReviews]

Hi Ken my take is...I would go with the D4 if I were charging a lot of Ni-MH cells and sometimes lithium. The VC4 is probably the way to go if you charge more lithium cells or need the two bigger bays for wider batteries. Both are equally good at charging (no signs of over charging or premature termination on either).

[@MrBazReviews]

I would tend to agree for bigger 26650 cells the faster charge rate might be a factor and you can charge 2 at the same time. I use this type only sometimes so single charging is fine for me. Now if Nitecore offered a D4+ with a choice of charging rates a little higher maybe even a test function that would appeal to me. I use AAA's quite a bit so the lower charge rate is useful to me. Not that I've had a problem with the VC4 for any cell types.

[@asrr62]

for me xtar is higher quality. ive owned both nightcore and xtar.

[@seanthebaptist6757]

VC4 is an amazing charger

[@nalexg513]

So I am buying two Sony VTC4 batteries but I would like a 4 bay because I will get more batteries at some point, what ports should I put the batteries in when only charging two? The first two ports or the two in the middle or does it not matter. Also Sony VTC4 are li ion correct so the xtar would be better for those than d4?

[@hans6304]

Thank you for the reviews and the tests you have done. You sure have helped many people. Take care and best wishes.

[@MrBazReviews]

Thanks appreciate the comment

[@adoniscmj3212]

The problem with the VC4 is it doesn't charge all 4 cells at .500 ma instead it charges at .250 for each. It is super slow, so I used a usb meter to check the amps and voltage it draws and it was under 1 amp charging 4 batteries through USB, so I used a 5 volt 2 amp transformer and it was faster, but USB is slow. I used a usb adapter that is capable of two amps output as well. I wished I had purchased the Nitecore instead. It plugs into the wall, so it must be better than the VC4.

[@MrBazReviews]

I've not found that problem I use a smart USB charger and it's capable of providing over 2.0 amps output so with 4 cells you can get 0.5 amp per channel. The D4 is the slower charger real world though both are quite good for what they offer

[@adoniscmj3212]

Nitecore has a new charger that I may get, It gives you up to a three amp charge, for those times when you just can't wait, but in reality that is too much current. My go to charger is still my 6 bay Efest charger that can fast charge two of the cells at 2 amps each or it does all at 1amp or .500. I love it, but it gets hot, so you have to keep an eye on it. I don't understand why they didn't put a fan in it. I may add a small one eventually.

[@BuskerLia]

Do you have an updated video on chargers or do you still feel these are both good options?

[@MrBazReviews]

Nitecore have not updated the D4 (it's still good but can't take 21700 cells), Xtar changed the port to a type C on the newer model, but it's the same charger. I didn't think it was worth making a new video just for that. If Nitecore do a new D4 I would make a new video. They're both still good chargers, just depends on the battery type you are using and if you want a mains or USB charger

[@BuskerLia]

@@MrBazReviews Thanks for the reply! I'm charging 18650B batteries. I bought the Nitecore i2 before watching your videos. From the manual instructions, I think I'm ok using the automatic detection, but am not 100% sure. I'm not super happy that when you tested the batteries using the i2, they weren't at full capacity. I'm thinking about returning it and getting something else and wondered if either of these would be better.

Hy ! Great review ! Y recently purchased a Nitecore D4 charger & would bother you with a question ! ? On a flashlight witch uses 3x AAA batteries in an adaptor (size - 61mm long) ! can y use a 18650 li-ion battery without protection (they are smaller 65mm ) The ones with protection are longer 68.9~mm & wont fit in the body ! Will the D4 safely charge de battery without protection , Or do y have to manually select the peak value ? Thx !

[@MrBazReviews]

D4 can like most charge unprotected 18650's so no worries on that it auto shuts off entirely when it reaches the charge voltage.

[@sisza011]

How much you will rate for the vc4? Compare to vc2 plus which one is better for ecig battery

[@MrBazReviews]

They can both charge 2 x cells at 1.0 amp max so not much difference. Display is down to taste if you only need to charge 2 batteries I'd go with the VC2 Plus smaller and more compact also has USB output so you can use it as a power bank

[@zanhuilee1164]

Hi, wish to ask, I am aware of charging with low current Ampere is better for extending battery lifetime As we only charge two battery with Xtar VC4, will 1A too high for a new battery so we should always prioritized using inner two 0.5A slot or it is okay to use the 1A slot? Will the trade-off be significant for charging time and battery lifespan?

[@MrBazReviews]

I use 1A for 18650 or larger, for smaller cells Li-ion CR123A/16340 or 14500 0.5A is better AA I charge at 1.0A and AAA at 0.5A It is true high current will wear cells out faster, but those speeds are pretty safe for those battery sizes. If you fast charge a 16340 at 1.0A is will wear it out quicker. Most 18650's will take a slight hit at 2.0A (not much), but higher charging will increase wear on them.

[@zanhuilee1164]

Thank you very much, well understood, this is a real good review and very informative. Ordered VC4 and couple of Xtar 18650 3500mAh after watching your video, do you think it is a good practice to charge them at 1A?

Pretty much they all do say for example 4.20V and be 4.17V or near there they tend to read higher than actual voltage. Main thing is, they terminate charging and the VC4 is accurate on that tends to charge a little more than Nitecore chargers

Another great review Mr. Baz. At 10:50 you show a charger that does has test functions built into it. In fact you refer to and show this charger in several of your videos but you never show the name or model of the charger. Since you keep using it as your standard I'm most interested in knowing what it is. Thanks in advance.

[@MrBazReviews]

There are other chargers I have reviewed that do (ie test the internal resistant and others that have a full discharge and capacity test). The VC4 counts the mAh put into the cell which might be of some use if the battery is flat, if it's not then you won't get an accurate "real capacity" The other charger is the Foxnovo and there is a video review here of that model: kzbin.info/www/bejne/sKW3qYxolrqcjqM That does a full discharge and test on batteries ie you have the real capacity, but there are downsides too Playlist for chargers and batteries some other ones have test functions (the newer Miboxer ones) kzbin.info/aero/PLPDCN48jxW_vualtWC8IuQCVTKFbBVmBR Hope that helps

[@szekerkakende1096]

I couldn't clearly understand, which one do you recommend for the vtc4-s?

[@MrBazReviews]

As I say they are close on charging performance, the Xtar is USB Powered which could be a con or a pro (if solar charging etc). Xtar faster, the D4 has the option to reduce charging current making it a better choice for smaller lithium cells. I'm not sure what batteries you are using if it's 18650's and 26650's the VC4 is a bit faster, if you are more mixed use the D4 might be a better bet

[@szekerkakende1096]

[@MrBazReviews]

No problem let me know how you find it. Thanks appreciate all the support will be doing some giveaways soon so stay tuned!

[@FM-fn7eo]

which one is better ?

[@MrBazReviews]

Depends on your needs I use NiMH cells quite a lot as well as lithium so I find the D4 better (I can set it to a lower charge for AAA's for example). If you use a lot of lithium cells the VC4 has some advantages (faster charging) Other consideration is USB power or mains the VC4 needs a decent 2.1amp USB port to work at the highest charging speeds, the transformer is built into the D4. Pros and cons for both models there isn't a lot to pick between them in charging performance (both terminate correctly and don't under or over charge). Hope that helps a bit

[@gregr1154]

D4 in this case. the VC4 looks good and has nice features, but being forced to find a strong USB charger to work with it is retarded. if they gave to a mains AC option like the Nitecore does, it would be a coin-toss decision. but they don't, so i'd quickly vote D4.

Mr Baz, your reviews are excellent. Do you know if there are any good smart chargers which can charge four 26650 protected batteries side-by-side?

[@MrBazReviews]

Hi I have not used any myself that charge 4 26650's at the same time I'll have a look around to see if there are ones available

[@DeksZagreb]

I've been looking at the Liitokala chargers because they can show both the internal resistance and the capacity of the battery cell on the display. Yet even their largest model Lii-500 can hold only two 26650 batteries at a time. Ideally, a good charger would have these qualities (capacity and resistance on display, among other things) and enough place to charge four 26650 battery cells at the same time. This would allow us to leave them charging over night at 10% charging rate (500mA for the 5000mA cells) so that we could use them next morning during diving. You've made some awesome reviews, did you consider the idea of making a video test of the best 26650 5000mAh to 5500mAh battery cells available in UK/EU at the moment? This is the battery test I often use to shop for 26650 batteries: lygte-info.dk/review/batteries2012/Common26650IndividualTest%20UK.html

[@MrBazReviews]

Well I'm working through the batteries slowly I sometimes buy some in to test got a few sent, over time it will build up. I test the capacity and internal resistance and add anything else I have to say if applicable. It would be very time consuming to do detailed tests so I'll leave that to the site you mentioned. Only other option is to get 2 x smaller chargers say the VC2 plus which can handle 2 26650 cells at a time (and can charge 0.5/1.0 amp). Why not charge at 1.0 amp? It won't degrade the battery performance in any way, you can charge 18650's at 1.5amps without hurting the recycle performance

[@DeksZagreb]

Well, I'm old school and we were taught that the lower the rate (8% to 12%) - the longer the duration of the batteries (less capacity percentage drop). It does not have to be that way with newer LiPO cells with advanced BMS but I guess old habits never die. I did notice that SOME LiPO and LiFePO4 cells capacity drops drastically if charged at a higher rate. But that could be up to the quality of the manufacturer. More than five years ago some A123 cells were extraordinary compared to the rest, but today there are many manufacturers who have caught up with the LiPO and LiFePO4 demand. This was noticeable on largers cells (which we were buying), but smaller cells would have a very abrupt capacity and power drop. Thank you for your fast replies, it's a good idea to get two chargers. I'll definitely buy a Lii-500 cause it has a neat resistance and capacity check on display and a reserve unit with only two 26650 cells.

[@MrBazReviews]

Depends what cells you are charging if it's high capacity Li-ion the Xtar is faster, if you use a mix and smaller cells then the D4 might suit better. Neither are hard to use, the Xtar adjusts current based on the slots you use so middle ones 0.5A, outer 1.0A..or more than 2 it's 0.5A. The Nitecore is 750mA unless you adjust it down for 2 slots so you will want to us the Low mode for CR123A/16340 or AAA cells

Then it's down to charging speed if that's important to you and how many cells you are charging

Can the vc4 do a discharge test?

[@MrBazReviews]

No it can't do that nor can the D4

Yes you can works fine though you want a 2.1 amp output or higher for max speed you can run it on less

Hi Mr Baz ; I will charge both low ( 1000 mah exp.18650 battery) batteries. Which one is healthier for you? D4? OR VC4? and which one better revives the battery showing 0 voltage? D4 or VC4. I will choose and buy one according to the information from you. Please answer. Thank you . .....a very successful review....

[@MrBazReviews]

D4 can't do 1.0amp it's 750mA so maybe the VC4 is the best option for you. Also consider Zanflare C4 quite decent for the price.

[@ibrahimylmaz4197]

@@MrBazReviews There is no zanflare c4 in the country where I am. Does vc4 provide suitable current for low batteries (700-1000 mah)? I know it gives at least 500 volts. Isn't D4 better, which gives 0.375 volts for low batteries in this case?

Make sure it's fully discharged/run down is it Ni-MH? Usually they are empty at about 1.0V, charge it and count the display it shouldn't be far off, unless they are low grade cells

[@NattyCaddy]

i have smok gx350 vape mod and it takes 4 18650 batteries and i use the lghb6 batteries which are 1500mAh with nominal voltage of 3.6 and discharge of 30A. What type of battery charger do you recommend for charging 4 of these types of batteries at the same time???????

[@MrBazReviews]

Both will do the VC4 is faster, also there are quicker chargers if you need it but at 1500mAh you can't charge as fast as higher capacity cells. MC4 is also worth a look cheaper and same charge rate as the VC4 (single LED though) half amp for 4 slots or 1 amp for 2 slots.

[@jryandl]

Thnank you for this great review! Keep it up! :)

[@MrBazReviews]

Thanks will do should get a few new chargers in for testing soon

[@apaarjain]

i want to charge four 18650/26650 3.7 volt batteries. which one would be better for fast charging?

[@MrBazReviews]

VC4 charges at 0.5 amp for 3/4 cells D4 0.375 so the VC4 is faster. Neither are what I would call fast chargers you can charge 2 cells at 1.0 amp on the VC4 or 0.75amp on the D4. If you are using 26650's a lot (ie more than one charging) the VC4 is the better bet it can fit two cells, D4 one if it's button top (flat top might fit 2). If you want faster charging speeds ie 1.0 amp on all four bays you'll need to look at a different model.

It's OK for Li-ion cells ie 18650's they are bigger and the heat isn't a problem on those. But I think there are better chargers the UM4 is also worth a look I did a review on that recently. D4 is solid, but getting on a bit now, VC4 is reliable if you can live with the barrel connector. I would expect a few updated chargers this year but those ones I mention are good.

[@mamadouamadou9708]

Thanks for the efforts you putting in to make these Videos for others. Will the D4 allows you to check the true capacity of these 18650 batteries?

[@MrBazReviews]

Hi Mamadou thanks for the comment. Neither can test the true capacity of the batteries the VC4 can tell you how much charge you have put in (that will only be useful if the cells are fully discharged and it's not as accurate as a proper tester which discharges the cell and measures how much current is taken out not put in). D4 has a timer not a mAh meter. The VC4 might be more useful for a basic idea, but if you look at the timer on the D4 and the approx. charge rate (it will drop off later stages of charging) that might give you an idea of the cell capacity. I use the Foxnovo F4S charger/tester for capacity testing it's quite accurate but has an annoying "beep" when it's finished. I am hoping to get around to a review on that charger maybe in a week or so. I use it mostly for that. Hope that helps a bit

[@mamadouamadou9708]

which one would you recommend to check 18650 true capacity.

[@MrBazReviews]

Only the Foxnovo would to that properly I'm not too impressed with the loud beeper so I struggle to recommend it as a primary charger. The Xtar might suit you better as it will give you more idea of the capacity. I hope both makers update these two chargers to include a test option it would be quite useful

[@omgwtfbbqstfu]

Both are effectively obsolete because they lack this core ability of a smart charger, unacceptable in 2017.

[@MrBazReviews]

Yes and no they are chargers but not testers it's not always needed the testing function. But I would like it to be included, sometimes you get obvious signs a battery is poor. Useful to have but if they add it likely to bump up the price we shall see both could be due an update shortly

[@kinderkid360]

i only need a charger for 18650 and AA batteries what would you recommend

[@MrBazReviews]

Do you want USB charging or mains? That would be my main decision. VC4 is a bit faster for charging both are spot on for the charging quality nothing to pick between them in that regard. For home use I prefer the D4 if you travel around a bit the VC4 might be better for you.

[@kinderkid360]

it would only be used at home so charger doesn't matter

[@gregr1154]

get the D4. the VC4 looks nice but its reliance of a strong USB charger is absolutely idiotic.

It would have made more sense to include the USB mains adapter for the VC4 rather then making it an "add on"

Mr Baz Reviews hi Sir i would like to ask how many hours do you charge a almost drain battery 3% its vtc6 thanks

[@kosztaz87]

We need a charger, where you can adjust the charging voltage threshold. If you charge li-ion cells only to 4.1v instead of 4.2v, they will survive significantly more charge cycles = much more economical.

[@MrBazReviews]

There are very few chargers that can do that, this is one... bit.ly/2hIg4tf Two ways of looking at it you can see which chargers terminate a bit less than 4.2V, or just don't let the cells run down charge them at say 20% levels rather than the lowest point.

D4 Does not have the 0v activation / repair which is a shame as I just ordered one. Nevermind it seems it does from your video, although the specs don't mention it.

[@MrBazReviews]

D4 does have an activation feature, but it's quite short as seen in the video with a Ni-MH cell. Thus I had to re-insert it again to charge. It's not that long about 5 seconds, the Xtar has a much longer activation time thus it's more effective

[@jeffreystroman2811]

Hey, I'm a broadcast electronic engineer, 20 years+ exp. Out of all these videos I've spent so much time watching I've yet to see anyone actually test these with a current dvm hooked up. Well I just checked my brand new no record d4 and my results are puzzling enough that I'm compelled to comment. I need much more time testing b4 I go into it, but did anyone know that every time it shows the voltage measurement it's charging current goes to zero? That is essentially pulsing at .3 hrs, (once every three seconds) in many cases the current read out was only telling me what was supposed to be happening as opposed to, you know, MEASURING THE CURRENT.

[@MrBazReviews]

Of course both chargers will charge any 3.6/3.7V 18650 Li-ion it just depends on if speed is important the D4 is a bit slower, the VC4 is faster but I've also looked at other fast chargers if you need quicker charging (ie 1.0amp on 4 slots etc)

@@MrBazReviews how slow is the D4? If I charge all 4 18650 batteries how long would it take? 1h? 2?

Quite a while all 4 slots 375mA so divide capacity by that, VC4 500mA (all 4 again). They're OK for 2 batteries 750mA and 1.0 amp but a lot slower for 3 or more just bear that in mind. I did look at some 4/6 slot chargers the 6 slot one is pretty quick I think it's aimed more at vapers using quite a few batteries it can do all 6 slots at 1.0amp or 3 at 2.0amp one of the faster ones I've looked at. kzbin.info/www/bejne/gZDQcn5thNh_nrc

[@MrBazReviews]

Stick with the high VG (say 80%) it's smoother if you vape at high power levels, if it's lower you can go for 50/50 but it varies on quality. If you use nicotine use only low levels it will tear you up I don't vape at big power so 50/50 is alright for me Dekang is OK for budget juice

@@spotlight761 Then there would be no way to offer 1.0A charging. It isn't a problem for a simple charger IMO you just use the middle slots for the slower charging speeds, 3 or more cells are 0.5A too so you can get satisfactory results for AAA cells. The only other way of doing it is with slot contacts so shorter cells charge at half and amp, but Xtar have lost their mojo recently the VC4s and VC2s are plain not good chargers

Those are reasonable points to make for the USB connection. I'd prefer if they included a charger for the USB output rather than an add on item. Solar charging is an option though would require a fairly high output panel to get decent rates on all four slots. I tend to use single or dual slot chargers for solar panels

Nitecore chargers are absolute trash. I've bought two within the last year and both ended up literally burning out on me. Both chargers were charging then suddenly stopped charging and smelled like burning electronics. I will NEVER buy a Nitecore charger ever again. I just bought the XTAR VC4H and currently using it right now. We'll see how well it works. I do have a smaller XTAR charger which has a cover for the batteries and doubles as a power bank. I used that for going on about 6 months now and it works great. I just needed a charger with 4 slots instead of 2. I do wish the VC4H had an indicator that showed the current charge of the battery when it is put into the charger, like the smaller 2 slot xtar charger has.

If you buy something and it breaks you should claim the warranty on the product. Some might find experiences different with various makers. I was hoping Nitecore would update their range. on the other hand Xtar were disappointing with some I used (VC4S)

Xtar VC4 cable is not that big a deal. You can make one. If for some reason you ruin it... The best one for the money. VC4 just because it's portable. You can make a USB C cable to fit it.
