And the theme for this week seems to be "Have a backup!" I know for me personally, it is a pain. I only have one battery. It lasts about 6 hours of chain vaping (which I do all day long, since giving up analogs). This means that around 2 pm, My battery dies. Then for the rest of the day, it is "vape, plug in, vape, plug in". So yes, if you can afford to have a back up or six, do yourself a favor and get them! No use making your vape experience a stressful one.
I do have to report, that so far so good. No analogs for me. I'm hanging in there.
