MagSafe battery packs have changed portable charging for iPhone users. Unlike old-school wired power banks that require a cable to charge your phone, MagSafe batteries snap directly to the back of your iPhone, providing a very easy charging experience. They’re convenient, compact, and perfect for those who want to avoid carrying extra cables. The ESR Qi2 MagSlim Kickstand power bank builds on these benefits, adding some nice features like a kickstand and LED display, making it a great option for charging away from a wall adaptor.
