Does Key or Carabiner have a battery?
Key and Carabiner are not batteries, which is why they are so thin. Our cables are just like your standard white Apple charging cables or a Micro USB cable, only rugged and portable. They plug into any powered USB port (computer, wall charger, external battery pack, etc.) and then into your phone/device and "Voila!", you're charging. If you're looking for a battery, check out our Battery Packs page on the site.
