Anker's Zolo Power Bank, a portable battery pack that offers impressive capacity and speed, and integrated USB-C cables and a sleek digital display for $50. With a 20,000-mAh battery capacity, the Zolo is capable of charging any phone multiple times and can also be packed for travel. It also offers a convenient digital display and can easily replace one fast charger on the move. Despite its pocket-friendly size, the power bank's compact size and number of outputs make it more than make up for its size. Anker's product is not perfect but checks the important boxes, including the ability to replace one quickly.
