Can anyone recommend a battery-powered or rechargeable hairdryer for use at the swimming pool? I and both girls have long thick hair. I am so tired of either queuing for ages at the end of swimming lessons with most of the hairdryers broken Do such things exist? (And if not, why not - how different from a cordless power drill is it?!). What does everyone else do? (Clearly, at my pool, we all just queue. For the one working hairdryer. Pre-refurbishment they had sockets and you could just plug one in. Now I can see why they got rid of those....)
