I believe this has been fixed on all of them. I have the newer C4 that has the discharge capability, and it works great. The only downside is the super noisy fan during discharge. MiBoxer needs to put a function in that discharges cells to 3.6v and stops, to use as a battery storage function.
Have any of you received this charger? If so, can you provide some feedback?
no no update so far, i asked Leo and got no response.
I would be very interested in reading HKJ’s review of this charger. I just bought four Nitecore SC4s (although I already have quite a number of XTAR chargers, ranging from the tiny MC1 Plus, to their flagship Dragon), and have been very pleased with their performance and feature set, for the price. They were purchased through a BLF Group Buy. There is no way I’d have purchased them at full retail. They’ve been the nicest Nitecore chargers I’ve owned, thus far; and at the price I paid, I have no complaints about them.
I’m finding the feature set and the ability to charge four 26650s at 3Amps simultaneously, appealing; but the current price on Amazon puts these at nearly twice the cost of the SC4 units I just bought; so it would have to be available through a Group Buy, or something.
Also, I’m not sure if this is a fan-cooled unit. If it is, that would be a hard pass, for me. I just don’t like fan-cooled devices, at all - especially if I would have a bank of four of them right next to each other. The fan noise would drive me crazy.
The SC4s do have a slight whine; but to me, the sound is negligible, even with the four units right next to each other. Of course, opinions vary.
I will look forward to reading more about this new unit, as time passes.
Off topic
David what do you do for the need to charge 16 batteries at once?
Wish I had a use for my lights lol
I find fluorescent lighting utterly depressing; so, when I’m at work alone, in the evenings, I ceiling bounce maybe a dozen lights to thoroughly light up my work area.
Whenever I come home from work, all the batteries I used, get charged, so they’re good to go, the next morning - without fail. I’m a stickler for leaving the house with lights that have fully charged batteries, and having plenty of alternate lights, to light whatever may come my way. I carry a dozen or so lights in a bag, with my multi-tools, and other stuff.
I like to use a Pelican 1010 case to EDC backup batteries, in that pack.
At home, I do the same, so I can have the kind of light (tint) I want, and I prefer ceiling bounced light, over direct lighting any day of the year. I’ll place a light on either side of my computer monitor, to reduce eye fatigue for late night computer use.
I’ll place another pair on top of either stereo speaker, kind of behind me, and off to my right; and if I want more light, I can place a pair, one on either of two sets of DVD towers, on the wall across from the speakers.
Sometimes, I’ll even mix and match two different tints in each area, for just the right color.
I know - I’m fanatical about having nice tints, to light up an area; and quite a few of my more recent purchases have been lights with neutral and warmer tints, so there’s no shortage of choices.
About once a month, I top off all of my 18650 batteries, whether they’re installed in lights, or not, pretty much religiously - and I usually do this at higher charge rates. I don’t care if I lose few cycles, down the road. It’s still a lot more economical than constantly changing out primary batteries, I never suffer from “guilty lumens” lol, and my lights are always prepared for any eventuality, on a moment’s notice.
Having multiple chargers makes it easy to quickly charge a large number of batteries, so I don’t have to take all day completing the process (I have 57 18650 lights, running on 69 batteries, so the more chargers the merrier!
A good portion of my AA lights also use multiple batteries, so I can charge a slew of different battery types, simultaneously, whenever I feel like it.
Some of my lights use two to four batteries, so the quantity of batteries used adds up, pretty quickly.
When there’s a power outage, I pretty much supply the house with lights. I could probably light up the entire house for at least a week, very nicely. Unfortunately, we rarely see power outages, and they usually only last a few minutes or so. A couple of days ago, we had a planned power outage that lasted almost twelve hours, but most of those hours were during the day, so that sucked.
When I do any kind of job that needs lighting, I have plenty of lights to choose from, and I have no qualms about using multiple lights, simultaneously (often, ceiling bounced).
Whenever I do indoor EDC (or other) still photography, I use a combination of lights and placements, to give me what I want, since I can’t really afford a bunch of fancy photo lighting equipment, and since I already have plenty of lights with neutral and warmer tints, to do the job. It gives me a lot of control over the overall quality of light for the picture.
A use can always be found for a good light - or bunch of lights 
Not that I’ve utterly derailed the thread - is this charger fan (actively) cooled, or heat sink (passively) cooled? It’s very important to me.
You could replace all those lights with a mere 2 or 3 Q8’s
Now that is true flashaholic.
Well - yes, there is that.
Would someone please do me a favor (if you’re able) and post a picture of a Q8, standing in between a BLF A6 and a Convoy C8? I kind of want to get a size reference of that Q8, relative to other must-have budget lights lol.
Thanks, in advance
LOL thanks for the reply David.
If there was an power outage. You could prob supply the whole street with lights. Not only yours.
I haven’t had a power outage in like 6 or 7 years. Only got that one cause a bush fire hit some power lines.
Sorry for the derail. Back on topic :person_facepalming:
I am in for GB too.
Ahhh. thank you kindly!
No problem.
I agree, however at this price point I’d expect it to be a very good charger before considering a purchase. Will look forward to HKJ’s review.
I’m interested even though it doesn’t appear to have a discharge capacity testing mode, but the price on Amazon is significantly higher than the $50 you’ve quoted.
Good to know, not interested at this price point without that feature, sent an email to miboxer to see if I can get a PDF of the manual.
Miboxer sent me a copy or the manual last night so I’ll be looking through it in the next couple of days and hoping to see HKJ’s review when it comes out. However I received the Zanflare C4 yesterday and love it. I’m thinking that with the price point of the Miboxer C4-12, it’s going to have to go some for me to buy it now that I have the Zanflare C4, time will tell.
I also found the $60 price point unattractive, but the US Amazon price has now been lowered back down to $49.90. That works for me as I also have Miboxer C4 and C2-4000 and other chargers which can do analysis on those infrequent occasions when needed.
One of the best things about these chargers is they don’t decide for me what is the most important thing to display about battery charge state, ~% Charge, Voltage or Current. They provide all three (in NUMBERS, not vague LED “bars”) and let ME decide, which I appreciate. Thank you Miboxer.
