This tag collects all of CellularNews’s articles about battery capacity, written for anyone who has ever wondered how long their phone or power bank will actually last. Whether you are shopping for a new portable charger, trying to understand the specs on a battery pack you already own, or just trying to pack for a flight without getting your gear confiscated, these guides cut through the jargon and give you straight answers.

The articles here solve two main kinds of problems. First, they help you compare and choose the right power bank for your needs. For example, you can read about how long a 10000mAh power bank will last versus a 20000mAh model, and learn exactly what to look for in a power bank before you buy. Second, they clear up the practical rules and basic electrical terms that often trip people up. You will find out what size power bank is allowed on flights, what the “Ah” on a battery actually means, and even how many amps are in a standard AA battery.

These articles help you make smarter buying decisions and avoid common mistakes. Instead of guessing, you will know how long a 5000mAh power bank can keep your phone running, and you will understand the difference between milliamp-hours and amp-hours so you can compare batteries with confidence.
