Whilst away snowboarding with friends, I realised that whilst we have various camera battery chargers, every night all of us need to charge multiple iPhones/iPads. If I could wrap most of these devices up on one plug, it would mean we can free the rest for cameras batteries etc. However, my Amazon research has failed to identify a device that does this well and does not receive criticism for struggling to power more than one iPad or two iPhones. In terms of priorities, charging multiple iPhones seems the main one - as most friends own them. If it can only do one iPad then that's not so bad, but more would be a bonus. I'm looking for a UK plug, as I have a couple of handy adaptors that turn one European plug into two UK plugs; and would buy similar devices for anywhere else I visit.
