phone charger logistics for a 3 couple airbnb... how do you not lose them

right so we did our first 3 couple airbnb weekend in the cotswolds last month and it was brilliant but the chargers situation was genuinely chaotic. 6 phones, mix of iphone and android, 3 watches, an ipad, a kindle and the bluetooth speaker, all needing charge at various points... by saturday night nobody knew whose was whose and one of mine ended up in the wrong suitcase going home. so how do you handle this when youre away with multiple couples — colour coded? labels? does one person bring the power strip and lay it all out... ive seen those little leather cable wraps but is that actually a real solution or just instagram nonsense
