The Galaxy S26 supports 45W PPS fast charging. Therefore, always choose a power bank that explicitly lists PPS compatibility. Standard USB-PD banks will still charge your S26, but only at reduced speed. Fortunately, all five picks in this guide support PPS.

For daily use, a 10,000mAh bank provides roughly 1.5 to 2 full charges. For longer trips, however, a 20,000mAh bank is a better choice, as it delivers approximately 3 full charges. Additionally, real-world output is typically 60 to 65% of the rated capacity due to conversion losses.

Most 10,000mAh and 20,000mAh banks fall under the 100Wh airline limit. As a result, they are approved as carry-on items on most airlines. However, power banks must always travel in carry-on luggage, as they are not permitted in checked baggage.

Wireless Qi2 charging is convenient, but it is slower than wired, typically reaching 15 to 25W. In contrast, a wired PPS connection delivers the full 45W. Therefore, use wireless for passive top-ups and wired when you need fast charging.

Slim blade-style banks fit neatly in a bag. On the other hand, compact bar-style banks like the Cuktech Mini fit in a pocket. High-capacity banks are larger, but the trade-off is worthwhile if you also need to charge a laptop or tablet.

A 3-port bank like the Anker 737 lets you charge your S26, a tablet, and earbuds at the same time. Single-port banks, meanwhile, prioritise compactness. It is also worth checking whether wattage is shared across ports, as shared output can reduce individual speeds.
