Read our Best Power Banks and Best MagSafe Power Banks guides for our recommendations. There are two main rules about flying with power banks, and they’ve been in place for several years now:You must have power banks in your carry-on. Use outlets at the airport to top up your gadgets before you board and minimize the need to use power banks during the flight. If you’re looking for a good, reliable, safe power bank, I recommend the Nimble Champ ($60) or the Anker Laptop Power Bank ($95). If you have an iPhone or Qi2 phone, consider one of the best MagSafe power banks.
