4 of 5 Fast charger review October 5, 2021
Reviewer: Kirk S. from Milwaukee , WI United States  
The charger works as expected but it could be better. It still uses USB-A style connectors for both the connection to the charger (mini usb-a) and the connection to the power source. Also, the charging cord is short in length. As a result of these charging cable issues I docked it one star.
