*** FIT, FINISH AND SIZE ***
The MiBoxer C4-12 is made out of ABS plastic and has a mild "texture" which gives the appearance of a subtle sheen as well as helping to reduce the visibility of finger prints. Size-wise, this charger is significantly bigger than the Opus, Littokala Lii-500, Xtar VC4 and Nitecore D4 among others. It is even wider and more spacious than the Zanflare C4. The size is just a little bigger than 4.5"x6". It's about 1" thick.
*** SLOTS ***
All 4 slots are evenly spaced, which helps make it easier to insert/remove batteries from the center slots. When charging 4x18650 batteries, the spacing is perfect and it is relatively easy to insert all 4 cells. However, care must always be taken to make sure that you don't accidentally knock out an adjacent cell when inserting or removing multiple batteries. You can charge 4x26650 cells simultaneously.
*** OPERATION ***
* When multiple batteries are inserted, press button to cycle display between slots.
* When batteries are inserted, long-press button to enter current selection mode. Once in current selection mode, press button to cycle through the charge current options. The range is from 0.1A (100mA) to 3A. After you cycle past 3A, there is also an "Auto" mode which will determine the appropriate charge current automatically. When using 18650GAs, it chose between 1.3A - 1.7A. I like the wide range of charging options.
*** SUMMARY ***
Overall, the MiBoxer C4-12 is a good smart charger. It works well, especially for people looking to charge their cells quickly and it also looks nice. My favorite aspect of this charger is all of the information available on the display. For example, I like that it shows both capacity in percentage as well as the voltage. I also like that this charger displays cell temperature which is something most chargers do not do. You can charge cells at up to 3A but make sure that your cells are able to support that much current first. I mainly charge 18650s at 1A.
Since this charger can also support charging NiMH and NiCd and it is straight-forward to use, it is a good universal/family charger. It can also fit protected cells and the bays are nice and spacious. This is one of the few chargers which can fit 4x26650. When charging 18650s, there is a nice amount of space in-between each cell. You can even charge C and D cells, which is also rare. It does not support LiFePo cells.
The power bank functionality works well and outputs 1A although it only uses the 4th slot. So, if you need a ton of energy you will need to swap batteries to the 4th slot. Using cells as a power bank is also a good way to discharge cells (either for storage or testing) without "wasting" energy.
The only thing that I wish this charger did was automatically drain and charge batteries to analyze the battery capacity. This charger will show you the cumulative charge but you would need to drain the battery first in order to get a good approximation of capacity.
- Class leading charging speed (3Ax4)
- Automatically decide the optimal charge / discharge rate for battery type and condition
- Internal resistance meter to monitor cell health
- The slots are completely independent, and they can charge 4 different batteries at the same time
- Quality construction with beefy 12v 5A power supply
- Not compatible with 4.35v or LiFePO4 batteries (these are pretty rare)
- No discharge function to precisely measure battery capacity, however internal resistance measurement is good enough for most to monitor battery healthy
Overall, this is an excellent 4 slot high speed charger. The feature set is enough for most users. Personally, this will replace another brand as my main charger for AA/AAA and 4.2v 18650 batteries.
So anyway the C4-12 is a very cool charger. You've probably also read that it's quite powerful. 3000mA (3A) is nothing to sneeze at! The ability to act as a power bank is another plus, and which doesn't need to be connected to AC to perform its function.
It can charge just about any battery type except for LiFePO4. Lithium-ion cells charge to 4.2 and NiMH/NiCD batteries charge to 1.48 It SHOULD be noted that a completed charge will read at the "nominal" voltage...i.e 4.2 for lithium. This means if the actual ending voltage is 4.17 (for example) the charger will read 4.20 This is not a fault of the unit, many chargers do that, and a simple volt meter can verify the ending voltage.
It's as simple to use as any other. When one or more batteries are inserted, the charger senses what it is and uses the appropriate current. Smaller batteries with lower capacities receive a lower current. Large cells such as 18650 and 26650, receive the highest current. You can also select the current manually, for all battery types. But it's recommended for sizes such as 14500, 16340, and 18350, to allow it to make its own determination. Charging will cease when the capacity is reached, and "FULL" will be seen in the display.
Speaking of the display... it's great! It's bright and the numbers are clear and easy to read. Among the information given during a charge, is the temperature of the battery. And incidentally, should the battery ever get too hot, the unit will either lower the current, or STOP the charge entirely, so as not to damage it. Other info on the display, is battery voltage, battery resistance, a running total of accumulated capacity (mAh), type of battery being charged, a percentage of how full the battery is at that moment, and a running "timer" to show elapsed battery charge time.
The only control button on the unit, is the "slot" button, which is used to select between the active bays during a charge. It cannot select an empty bay.
I really like the C4-12. Large size batteries can fit without an issue, and overall it's very safe, reliable and so easy to use :-) Naturally each bay operates independent of the others, and completed batteries can be removed, while others remain charging. As others have mentioned, the only function it doesn't perform, is a discharge and test. It will tell you ACCUMULATED mAh from when a battery is inserted, but NOT TOTAL mAh (capacity) from a completely depleted state, unless THAT is the status of a battery placed in the unit.
The C4-12 comes with a two-piece AC adapter. If this becomes too bulky when travelling, you can use a "standard" 12VDC adapter... as long as the jack that connects to the rear of the unit is the same size. Just be prepared that an adapter other than the one furnished, probably WILL NOT supply the full 3A current! Most likely it will support up to 2A only.
I'm recommending the MiBoxer C4-12 for a number of reasons. Not the least of which is because it just does a really good job! Thanks to all at MiBoxer!
In the photos I've attached, make note of the one where TWO batteries are charging. Those are 26650's! -- which fit very comfortably next to each other.
