One thing I don't like about Baton, looking at their site, is that they don't tell you the mAh of the battery in the system. So you have no idea how to compare it to other pods in terms of whether you would need to charge a different system less or more than the Baton. My guess is that it's 800mAh or less, but that's just a guess because it's all I can do, and that's not right IMHO. But if it works for you, that's good.
