I took advantage of a grand opening, online sale from a vendor last week and purchased 3 liquids and recieved the innokin AIO kit for free. I figured I'd give it to my mother in law, who doesn't seem to like her ego style batteries. They hit too hard, and she's been complaining of a sore throat. I thought that perhaps a cigalike may suit her better. She'll certainly be more comfortable to be seen with it, which I think may be a large part of the issue. It was free with the liquid, so why not try? Thing is, the battery has been charging in the case for a couple of hours now, and the light is still red. Anyone know how long it takes this case to charge a 510?
