Updated 2026-07-23 · Power Bank Guide

The Steam Deck is a powerful portable gaming console that demands a reliable power source. When it comes to choosing a power bank for your Steam Deck, there are several factors to consider, including capacity, power delivery (PD) requirements, and portability. In this guide, we will explore the best power banks for Steam Deck, including the INIU 20000mAh Portable Charger (Flight-Safe) which is a great pick for its combination of capacity, fast-charging speed, and travel-friendly features.

Choosing the Right Capacity for Your Steam Deck

A good power bank for your Steam Deck should have a capacity of at least 20,000mAh, but you may need a higher capacity depending on your usage. To give you a better idea, here are the power consumption estimates for the Steam Deck:
