Thank you for coming back and giving me an encouragement! The charging cable can be plugged and unplugged to charge the battery while the machine is being used similarly to standard laptops .
Thank you for the helpful feedback . I wanted to use coiled cables that are angled in ways that do not run into one another, but they would have been too expensive / difficult to make considering I needed four different types of cables. If I do another project like this, I may go the extea mile!
