i own an anfibio multi and now the legend. Dont know if any of you folks also own any other n/m units, but the part that goes into the machine to charge and update look both the same. I also have the extra battery pack that goes to the anfibio. I dont have a need to hook the extra battery pack to the legend nor will i unless n/m says it can be done without voiding the warranty. Anyone know if the charging cords are the same? Also if needed will the extra battery pack from the anfibio actually power the legend?
