While searching for my first power bank, I came across the Anker Zolo Power Bank 20,000mAh (45W Max), currently available on Amazon for €29.99. Anker has a solid reputation, and this model looks like a practical option for travel and everyday use. Despite its large 20,000mAh capacity, it weighs just 364g and can reportedly charge an iPhone 16 up to four times. The upgraded 2025 version comes with two built-in USB-C cables, tested to withstand more than 10,000 bends. It also has an additional USB-C port and a USB-A port, allowing up to four devices to be charged at once. It supports up to 45W fast charging, including up to 40W for the iPhone 17 series and 45W for compatible Samsung devices. The battery uses upgraded CB-certified cells for improved safety and reliability. Key specs: Capacity: 20,000mAh Maximum output: 45W Weight: 364g Connections: 2 built-in USB-C cables, USB-C port and USB-A port Charging time: approx. 5 hours Battery type: Lithium-polymer Overall, it seems like a compact and versatile power bank with plenty of capacity and convenient built-in cables.
