Physical Attributes:

The C8 is made out of PC+ABS fire-prevention material, the plastic of the unit is textured and it doesnt contract fingerprints and is high quality feeling. The buttons on the unit are rubberized and may see some wear after long term use. Every slot is eqipped with a high precision sliding negative bracket that moves very smoothly and is made very well. The LCD is very bright and crisp and comes with a plastic seal over it for protection. The charger body can hold up to 8 18650s in unison or only 4 26650s in alternating slots. Unlike other chargers such as the Opus this charger makes full contact with protected 26650s on both ends and holds them in well.



Plugged in

Full of 18650s

Can only hold 26650s on every other slot but can hold 18650s in between

Cooling the Unit:

This unit doesnt have active cooling, it uses thermal throttling if the batteries get too hot the unit turns down the current


The unit is approximately 5.5” × 7.1” or 14cm × 18cm
The vernier wasn’t big enough to measure the top length but I measured from where it stopped being long enough and added them together and got ~ 7.1”

Display and selectable modes:

The C8 comes equipped with a large digital LCD display, the display shows voltage, current, charging time, mode, battery type, internal resistance and battery capacity data. The charger can repair “0V” batteries and when charging 4 batteries it goes up to 1.5A for Li-ion / LiFePO4, and up to 0.8A when charging 8 Li-ion / LiFePO4. Also its up to 1.0A for when you charge 8 Ni-MH / Ni-Cd rechargeable batteries. The best feature of this new UI is that you can set the charge current of all batteries inserted by the click of one button instead of going through each battery and choosing the current.


Battery types supported:

-NiMH and NiCd
-Lithium-ion (4.2V ICR, INR, IMR, etc.)
-Lithium Iron Phosphate

Battery Sizes Supported:

10340 / 10350 / 10440 / 10500 / 12340 / 12500 / 12650 / 13450 / 13500 / 13650 / 14350 / 14430 / 14500 / 14650 / 16500 / 16340(RCR123) / 16650 / 17350 / 17500 / 17650 / 17670 / 18350 / 18490 / 18500 /18650 / 18700 / 20700 / 21700 / 22500 / 22650 / 25500 / 26500/ 26650 / A / AA / AAA / AAAA / C / SC

Setting battery type- insert batteries into any slots then double click the [mode] button, then the battery types will begin flashing and you can cycle through the types with the [mode] button once again.
Setting the charge current- long press the [mode] until the amperage indicator begins to blink, then short pressed to the [mode] key will cycle through the currents, (0.1-1.5A)
Setting functions of every slot at once- long pressing the [slot] key will make all slot symbols flash in unison, from there you can long press the [mode] key to set the currents of all slots at once, if you double tap the [mode] key it will change all slots battery types

Wish list:
1- Test mode, I wish that this charger also had a drain and test function to determine capacity for all 8 slots.
2- Quick charge, I wash this charger has a quick charge function similar to the C4-12s 3.0A charging capacity, even if ot only charged quickly on the outer 2 slots or something similar.
3- ability to charge 8 26650s, it may not be necessary but if you make an 8 bay charger you may as well make it fit 8 26650s

Final thoughts:
All things considered the MiBoxer C8 is a great charger for the price, the 8 slots in this charger is great especially because not many chargers on the market have 8 slots. This charger is good if you have a flashlight like the BLF GT because instead of charging one set of 4 batteries at a time you can charge all 8 and have the light ready to go.

My favorite part of this charger is the intelligent charging feature, this feature makes it easy to use for anybody because all they have to do is put a battery in and let the charger do the rest, especially if you have it and someone who doesnt know how to use the charger uses it you dont have to worry about teaching them how to use it, its simply plug and play.
