Nice feature you have there… now the rumored cat is really out of the bag! :+1: 
Looking forward to this one
So, if two of the channels deliver 2A, then what do the remaining six channels deliver? 1A?
Or does it mean the remaining six channels cannot be used at all while those two channels run at 2A?
hello Pete
Thank you for your question.
what I mean 2*2A is, if there only 2pcs batteres in the charger, both channels can deliver 2A, and when you put 3 or 4 pcs batteries, the channels just can delivery 1.5A,
in the same way, if you put more than 4pcs in the charger, the charging current is 5*1A,6*1A,7*1A, and 8*1A.
Thanks
Is this what it means? :
1 x 2A max (remaining bays empty)
2 x 2A max (remaining bays empty)
….and when more than 2 bays are used, the 1or 2 X 2A goes down to:
3 x 1.5A max (remaining bays empty)
4 x 1.5A max (remaining bays empty)
5 x 1.0A max (remaining bays empty)
6 x 1.0A max (remaining bays empty)
7 x 1.0A max (remaining bay empty)
8 x 1.0A max
Am I correct?
yes, completely correct.
price? would love to see a C8-12 that would be monster.
I’ve got 2 C4-12’s so I’ve got 8 bays all of which can do 3A’s, I’ll just stick with those. Actually I think Miboxer should resolve the issues with current chargers rather than putting more in the market that may or may not work as advertised.
Actually mine both work fine I just don’t have a lot of confidence in them long term at this point
It looks nice but the slots are too close together. It lacks the spacing that the Gyrfalcon ALL-88 offers. Charging a bunch of 26650s or larger will be a problem. Make the slots wider on that Miboxer.
Huge +1 on this. I haven’t even looked at the photo until you pointed it out.
Ugly… well maybe just old school; I’d like to see someone do a new 8 cell charger like the Nitecore that has the batteries vertical in a cube shape for a small footprint… but with decent electronics of course.
I think the C8 is mainly aimed at 18650 cells.
Maybe a future model will be the C8-16 (8x2A) or C8-24 (8x3A). This will be aimed at multiple 26650 using a bigger frame.
It will take a lot of power and be pricey. I wonder if there will be a market for it compared to folks just buying two C4-12?
Miboxer C8 can charge 8 pcs 21700 Simultaneously
1.5A*4
0.8A*8
Li-ion(4.2V/4.35V)
Ni-CD/Ni-MH
LiFePO4
12V*3.0A input
by the way, all of Miboxer charger can charge 21700 with protected from now on.
the charging slot is 80mm can fit 21700 with protected batteries.
That’s a nice feature. :+1:
BTW, neither of your posts above have pictures showing, for me at least.
Looks great. Does it detect the internal resistance to automatically set the charge current? Can it display the internal resistance like the Miboxer C2-3000?
I wouldn’t worry about 26650, I predict they will die out as 21700 becomes more popular.
Why would you think that? Are you under the impression that a 21700 can match a 26650? Far from it. The 21700 is simply a container size in between the 18650 and 26650. That’s all.
The 21700 can’t match the 26650 capacity, but can deliver far and away more power. I’ve found this true in the Samsung 30T and iJoy 21700’s as compared to any 26650 I’ve tested, and there’s been quite a few.
But I for one will be using the 26650 for a long time, as well as the even larger 32650, as I have lights that do very well with these package sizes.
The MiBoxer C4-12 is a favorite charger of mine, I can’t see much use for less than 1A charge to 8 cells though so this new offering has no appeal to me.
The gap is closing and 21700 are being developed at breakneck speed compared to 26650.
The gap is not closing. Look again. Capacity of the 26650 is also growing. The 21700 is just a bigger version of the 18650. The battery chemistry and energy density is pretty much the same as an 18650. Development actually seems slow.
The reason the 18650 and 21700 have such high capacity for their physical size is because the big battery companies make them with their special mixes. This gives them high energy density. Unfortunately only smaller battery companies make the 26650. Their chemical mixes and energy density are not quite as good, but they are getting closer to the big companies all the time.
When you see the Samsung 48G with 4800mAh and a Littokala 26650 with 5000mah you can’t just assume they are the same. The 48G is only rated at 8A to 10A continous. The Littokala is rated at 20A continous. If you want 20A continous from a 21700 you have to move to a lower capacity version. I think the Samsung 40T 4000mah can do 15A continous. This is close, but you have to go another step down in capacity to the 30T 3000mah to reach 20A continous (The 30T can actually do 30A continous, btw). Maybe if Samsung did a chemical mix that gave 3500mah capacity it could match the Liitokala 26650 in continous output.
So you see, if you need 20A continous, you can use a 5000mah 26650 or a 3500mah 21700. There is quite a gap in their capacities.
If you need 15A continous, a Samsung 40T 4000mah can be used. In 26650 there is the 5000mah Liitokala or the 5500mah Shockli. I don’t think the 6000mah KeepPower has been tested, but surely it can do 15A continous. So you still have a decent gap, 4000mah to 5500mah.
Only if you need 10A or less continous output do the 21700 high capacity cells start to equal the power of the 26650. At these lower power levels is where we need the big battery companies like Samsung, Sony, LG and Sanyo/Panasonic do make a high capacity 26650. If they put their same high energy density mix in a 26650 container we would see 7000mah 26650.
At the moment, anything needing between 10A to 20A continous is advantage 26650.
Edit: Even at the 10A range, the 26650 has a lot of advantages such as less voltage sag plus a bit more capacity as well.
