External lithium batter chargers
What's the latest ruling on taking these external usb power banks as hand luggage so I can charge my iPad inflight? Googling doesn't give you a definite answer one way or the other. Most say don't pack them in hold luggage which I wouldn't otherwise it defeats the object. I also have a free single charge one given by EE, however after reading a horrendous story about it heating up I don't really want to take it.
