A few years ago, it was difficult to find a USB-C battery pack capable of charging a MacBook at a speed of 30 or 45W, but with Apple and other companies increasingly embracing USB-C technology for everything from smartphones to laptops, high-powered USB-C battery packs have become more readily available.

Higher-watt USB-C battery packs are ideal for fast charging iPhones and iPad Pros, providing power for MacBooks and MacBook Air models, and even charging up a MacBook Pro when charging speed isn't an issue.
