I. Introduction

When it comes to keeping your iPhone charged on the go, choosing the right power bank can make all the difference. This article aims to compare the performance of three popular power banks specifically designed for iPhones, focusing on their charging efficiency, capacity, and overall usability. The tests were conducted using an iPhone 15 Pro Max, ensuring real-world relevance for users seeking the beste powerbank für iphone. The charging conditions were standardized to eliminate variables, including ambient temperature (25°C) and initial battery level (0%).

Our goal is to provide actionable insights for consumers who rely on power banks for their daily needs, whether for travel, work, or emergencies. By evaluating key metrics such as charging time, number of full charges, and heat generation, we aim to identify which power bank delivers the best performance for iPhone users in Hong Kong and beyond.

II. Power Bank Testing Methodology

To ensure accuracy and consistency, we followed a rigorous testing protocol. Each power bank was fully charged before the test, and the iPhone 15 Pro Max was discharged to 0% battery. We measured the time taken to charge the iPhone to 100% using each power bank, recording data at 15-minute intervals. Additionally, we monitored the temperature of both the power bank and the iPhone using infrared thermometers to assess heat generation.

• Metrics Measured: Charging time (0-100%), number of full charges, temperature (°C)
• Test Environment: 25°C ambient temperature, no background apps running
• Tools Used: Infrared thermometer, stopwatch, Wattmeter

The tests were repeated three times for each power bank to ensure reliability. We also considered user feedback from Hong Kong-based consumers to validate our findings, ensuring the results align with real-world usage scenarios.
