I've got one of these and really like it. Charging is around 4 hours and I get a charge to last 3 hours with a sharp drop around 3:15 but I never use it in one shot as my max ride length is 40 min, so about 3 rides for me and if I forget to charge before the 4th, I need my backup light. I don't know how it compares to the plus version but it does a great job for my riding needs.
