You know this frantic feeling all too well: your phone's about to die, and you'd give anything for a spare charger. Thanks to a special holiday creation, that problem can fly straight out the window. We introduce designer USB bracelets you can just slip off your wrist and use to sync your phone to your laptop to give your cell some juice. Made for all iPhone 4 and 5 models and Android phones, the bracelets — designed by names like Mara Hoffman, Milly, and Rachel Zoe — are downright stylish and worthy of arm party status.

Buy them now on eBay for $25 — we say get one for yourself and one (or two) to gift for the holidays.
