The C4-12, for the months I’ve owed it, has been working absolutely perfectly.
It has a good internal resistance checker compare to most chargers, a very wide range of charge current, from 0,1A-3,0A for Li-ion, and 0,1A-1,0A for NiMH cells.
For large 26650s/20700/21700s, being able to charge at 2,5-3,0A is very nice.
I use the C4-12 as my default charger. I’ve accidentally allowed the spring loaded negative to slam home on a few occasions and the spring broke inside… relatively simple to fix. Like any charger, keeping the contacts clean keeps it accurate and likewise cleaning the ends of the cell works wonders.
I’ve been contemplating getting another one for those times that 4 bays simply isn’t enough.
I’ve had the C8 for the past 2 months and I really like it. No broken springs (fingers crossed) and it seems to charge just about everything we put in it safely and quickly.

I have the C4-Plus. I mainly wanted capability for a 21700 cell, and the C4-Plus was less money. The C4-12 provides more charge current, but my experience with most of my cells is that the internal resistance kind of mutes the benefit and I find 1 amp adequate. Also I didn’t care to have the USB power bank feature from a cell in bay 4. Not sure if the C4-12 can be powered by both AC and 12vdc, but the C4-Plus can.
C4-12 $45.99
C4-Plus $26.99
Those are pretty much the only differences that I know and the price is accordingly.
Someone already mentioned the new updated Miboxer C4-12 that has 2 buttons and now also supports LiFePO4 & LiHV batteries. I wonder if it’s already available for sale and where…
Miboxer did not want to repair my slot 3 affected C4-12 with the excuse they do not have authorized reps in AliExpress (and I bought it from similar link just because this was my only option). Just my 2c on their customer service and distribution activities.
More modest needs - just ordered a C2-6000. I had done some searching and the C4-12 is a complete beast. Very good price to charging options. What threw me off no 4 slot, at a glance, charge status (which cell/s is full). It seems you must cycle each bay. Also, the feature of time remaining till full seems to have been removed - there is no mention in any of the sites / comments. It shows on start-up (bottom left above “time”). Would have been a nice feature.
Had an Adeaska SQ2 which has a nice display but not %, IR, and modest 0.5 / 1.0 amp. µUSB broke but I was able to re-solder and reinforced with epoxy. The unit was erroneous since the start: with one cell 1/2 & 1 amp setting ok, w/ 2 cells this was inverted, i.e. 1/2 setting gave 1 amp and the 1 amp gave 1/2. The values were max though as the charge would change. Not really CC. Something awry with the electronics. Did the job for awhile - time to upgrade!
