I received the C2-4000 charger from MiBoxer for review.
MiBoxer has taken our suggestions from the C4 smart charger and the C2-3000 chargers and put them in the C2-4000 charger, which I like much more then the previous charges I've tested myself.
Here is what you get with the MiBoxer C2-4000 charger, inside the box you have the charger itself and the 120 volt power adapter. The power input for the charger is 12 volt 2 amp, so this can still be powered from 12 volt power sources.
Here is the C2-4000 compared to the other offerings from MiBoxer, the C2-3000 and C4 smart charger.
When you plug the charger in the screen lights up and displays C2-4000, when you insert a battery it tests the voltage and internal resistance to determine the best charge amperage to charge the battery at. The display will then show the approximate battery percentage, time remaining to fully charge, mah that has been put into the battery during the current charge cycle, and scroll through the battery voltage, internal resistance, and charge current.
The charger displays the same information when charging NI-MH batteries.
With this charger you can also charge Li-ion 4.35volt, LiFePO4, as well as the Li-ion 4.2, and NI-MH and NI-CD batteries. The charger will auto select the NI-MH or NI-CD charge option automatically by the voltage of the battery, and default to Li-ion 4.2 volt for higher voltage battieries, you can manually change the charge setting for a different battery chemistry if needed. Just make sure you select the appropriate battery chemistry for the battery your charging as it will default to the standard Li-ion 4.2 charge voltage when you insert a battery with over 2 volts.
Where this charger is different from the previous chargers from MiBoxer is that you can manually set the charging rate for the battery. For the Li-ion 4.2 batteries you can select from 0.2amp, 0.3amp, 0.5amp, 0.8amp, 1.0amp, and 1.5amp, which I think seems like a really nice range for the smallest to the biggest batteries you might charge. The NI-MH/NI-CD charge options are 0.1amp, 0.2amp, 0.3amp, 0.5amp, 0.8amp, and 1.0amp, which also seems pretty reasonable, it would have been nice to see 1.5amp option here too for the bigger NI-MH batteries, but at least it does have higher charge rate then previous models.
The display is very nice and can be read weather the backlight is on or off, the backlight will come on when you insert a battery or press a button, after a while if nothing is done the backlight turns off automatically.
This charger easily fits battery sizes from 10440 to 26650 as can be seen here, and has the charge rates appropriate for all of them.
The charger does have a cooling fan on the top next to the power port, I don't see any ventilation anywhere else on the charger.
So far I like the C2-4000 from MiBoxer, they really seem to be listening to our suggestions and making good improvements to their chargers. I hope they make a 4-bay version of this charger, it is simple to operate and still gives the user some options. For most people you can just plug it in and place the batteries into it and it will take care of the rest for you, but you can now choose some of your own settings if you desire.
I will update my thoughts after I get some more use out of the charger, so far I like what I see.
