5 of 5 Charger October 4, 2021
Reviewer: Madison from Texas  
The charger works great and stops charging to protect the battery from over charging and causing damage to the charger or battery itself. I keep a charger at work and charger at home. Plus the E4K flashlight came with a usb c cable to charge so you can also use that to charge the battery in your car or truck while on the road. No need to carry the charger itself from place to place.

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.
