I was expecting the MiBoxer C4 to be a 4 battery version of the C2-3000, but it is very different.
Here are features the C2-3000 has which the C4 doesn't:
Calculate % of charge
Calculate time remaining to full charge
Automatically adjust charge current to match internal resistance.
Seven manually selected charge currents (only 2)
1'5A maximum charge current (800mA)
Here are what I consider are some problems with the C$:
The display doesn't match the actual current or voltage:
It never reaches 4.2v when charging Li-Ion batteries. Typically it will reach 7.17v, then when the charge current stops, the battery voltage drops to around 4.15v, but it starts to discharge relatively quickly, and within 4 minutes, the voltage will drop to 4.11v.
The actual charge current was:
Single battery Low: 350Ma
Single battery High: 790mA
4 batteries Low: 340mA
4 batteries High: 740mA
Here are the manufacturers specifications:
And here are the graphs for Voltage v current:
