With a massive 60,000mAh battery capacity, the Anker 548 is the largest power bank I've tested, providing immense power for charging multiple devices.
The Anker 548 weighs over five pounds and, while not easily portable, can charge an iPhone 15 more than 10 times and a MacBook Air almost three times.
Its built-in LED light, offering three settings, can illuminate a space for nearly two days, adding significant value for outdoor use or emergencies.
Despite its size, the Anker 548 retains 85% of its charge after one year, showcasing impressive battery longevity and reliability for backup power.
