It's difficult to get answers to your questions because you are putting them all over the place
Please remember some people only visit the forum once a day and may not have time to read through a dozen posts. But the good news is you can help us out, if you keep all of your questions together it will be much easier for us to answer them
There is also a handy dandy edit button on the top right of your posts if you need to add something extra that you just thought of, or want to change anything.
Now to actually answer your question, no you cannot charge Pleo while running him, as the battery must be taken out to charge. And you will not hurt Pleo by turning him off and on.
