But with so many options, how do you pick the right one?
We’ll look at the best power banks for two main needs: powerful banks that are great for long flights and smaller, lighter ones perfect for everyday phone charging.

When deciding on a power bank, think about your lifestyle. Go for a high-capacity model (20,000mAh to 27,000mAh) with high wattage (45W-65W) and multiple ports if you use your tech very often or frequent flyer. Always check airline limits.
For the daily phone user, a lightweight 5,000mAh to 10,000mAh option is likely enough. Think about features like fast charging, wireless charging (for iPhones), or built-in cables for ultimate convenience.
No matter your choice, a good portable power bank will free you from the worry of a dead battery, keeping you connected and entertained wherever life takes you.
