1 of 5 Lacking.... August 3, 2021
Reviewer: DLG from Huntsville, AL United States  
This should have the same input's as your F1.  A full-size USB on one end and a smaller USB at the other end.  I have several 21700 batteries that I can use to charge items like your Leica / Nikon battery chargers but without a full-size USB, it's close to useless.

4 of 5 Works but has coil whine May 22, 2021
Reviewer: Noah from Wisconsin, USA  
It works how it is supposed to. The polarity protection has saved me from a mistake several times now. The only complaint I have is that it makes a faint coil whine. It is the type of thing that can only be heard when the room is pretty quiet, so not a huge deal, but enough to take away one star.
