   The backup battery lasts long enough to complete any activity in progress.
   Small details:
   – Even during normal use (not on batteries) there is a small high-pitched sound in the unit, only noticeable in a quiet place, but it is there.
   – The contacts are together, so large chargers will easily take 2 inputs, which is inefficient because only 4 are under battery. I recommend using a short extension if necessary.
