The lack of a charging symbol and no current being drawn shown in Escribe - apparently this can be down to a damaged resistor connection near the USB according to other threads. Unplugged the white connector, then re-attached it and very very briefly got a charging lightening symbol. Could be a duff connector - either way it isn't going to do the business. Yep, I have seen the 510 issues from some folks, mine appears solid. I do like the mod so it'd be nice to get a replacement that works out the box
