I'm going to Hawaii in 3 weeks and plan on discharging them before I leave. I just bought the USB adapter so I can charge my mobile devices to discharge the battery the day before if I need to but plugging in a USB fan is a great idea, didn't think about that.
Side question on the subject of batteries....I'm planning to bring a couple external battery packs to keep in our backpacks in-case we need juice for our phones/tablets at the airport or on the plane. Are those safe to bring on board even if their fully charged?
