Passport is the world’s first fail-safe global travel adapter created by Zendure.
The project which started on Kickstarter on 26th June 2017 has raised a total of US$217,053 out of their initial goal of US$30,000 from 4,887 backers.
Bought the Apple World Travel Adapter Kit before my flight to London in iStudio located in Changi Airport Terminal 3 for S$54.21. Since I was departing to London and have a valid boarding pass, I do not need to pay the 7% GST/tax, if not the normal price is S$58.
The Kit is designed to work with iPod, iPhone, iPad, Apple MagSafe Power Adapters (for MacBook and MacBook Pro), Portable Power Adapters (for iBook and PowerBook), and AirPort Express.
