6500 mAh / 200mA = 32.5 hours to full charge if battery is completely depleted. But in general i doubt that would be the case.

If your goal is to "grid charge" the battery w/200mA current off a 12V power source, then that device appears to be sufficient; however, you must provide PWM control of the battery fan during charging. 200mA may not seem like much, but it's enough to overheat cells in their insulated case even at 200mA.
If your goal is to somehow improve efficiency during driving by charging while driving, then no, it's not worthwhile.
