The power bank came in handy when trying to locate a friend to meet for a swim on Hampstead Heath (my phone was on its last legs - isn't it always?), and during last ditch attempts to keep my nieces and nephews entertained with games on long journeys (there's only so much I Spy any sane adult can handle).
