Remember ChargeCard? Nomad’s ChargeKey is even smaller at roughly the size of a standard house key (and just as thin, too). Clip this diminutive USB-to-Lightning charger onto a key ring and forget about it – at least, until your phone dies and you need a quick jump. It’s got no cable so it never gets tangled, sports a flexible mid-section to accommodate a variety of USB plug positions, and works with the full range of Lightning-compatible devices, including iPads.

Find it in Lightning or Micro USB varieties at AmazonĀ – $25
