Plus, it has dual USB ports so you can charge up to 3 devices simultaneously. It’s a bit of a Rubrik’s cube at first, so give yourself a couple of minutes to familiarize yourself with it before you leave home so you know exactly how to use it. Pack it along with this portable external battery for your smartphone and you’ll be set for any power eventuality.

  • Is does NOT have the Type C plug you will need in Switzerland, Austria, and most of African countries
  • It is NOT a voltage converter! In general, you don’t have to worry about voltage converters anyway. Most of your devices, like laptops, are already with dual voltage devices.
  • Is not appropriate for high power devices like irons, blow dryers, and coffee makers. But you don’t need to travel with your iron or coffee maker anyway, do you?
