So I am wondering, would it be possible to make a High Voltage USB passthrough. I have noticed som usb passthroughs are just the battery looking thing connected directly yo usb. Which I think runs on 3v and 5v. But the real question is, some of them, like the 2 510s I have has an inline battery that you can vape from and the battery charges from the usb. Well is it possible to put say a 6v battery system in line. Then vaping would take from the 6v, and they would just recharge slower. But if a 6v lasts at LEAST a day, then during the night it should be charged fully not including the "trickle" charge its getting during the day as you use it.\\Is this possible? Sounds like a good idea.
