Q: If I have a MacBook Pro Retina 13'' with no power left, how much (or to which percentage power-charge-wise) will a fully loaded ChugPlug charge it?
A: The percentage you can expect from a fully charged ChugPlug on your MacBook Pro Retina 13”, with no power left is about 44%.
Q: Can I leave the ChugPlug charging all of the time when I am not using it?
A: The ChugPlug has over charge protection, but we recommend unplugging the ChugPlug once it is fully charged. Leaving a battery plugged in after it has fully charged can negatively effect the battery’s ability to hold a charge.
