You don’t even need a separate cable! Every iPhone released in the past six years, including the iPhone 11 Pro Max, has supported wireless charging using the same standard Qi protocol that other phones use to charge.
People complaining about carrying around an extra (small, lightweight) cable are definitely not traveling with the hockey puck you need for Qi charging. Size and weight matters when traveling, and Qi chargers simply never get near the travel bags. Multiple 12 inch cables are far superior (space/weight wise)
