Best Power Banks for Tablets in 2025

In today’s mobile world, tablets like iPads, Samsung Galaxies, or Android slates are essential for work, entertainment, and everything in between. But their larger batteries drain fast during long flights, road trips, or all-day streaming sessions. A reliable power bank can keep you powered up without hunting for outlets. For tablets, you’ll want models with at least 20,000mAh capacity for multiple full charges, fast-charging outputs of 65W or higher (to match USB-C PD standards), and multiple ports for versatility.
