Hi @episakie your post was moved to the Alta forum area for more relevant responses. I have an Alta HR myself and have found that it's hard to read outside, too. It used to be a bit brighter, but it's a few years old. As for the charger issue, you try cleaning the connection points on your Alta and charger?
Best AnswerNot sure what to tell you on the charger. Is it the original one?
