A dead battery on your smartphone, tablet, or laptop is never convenient, especially when you're on the go. A power bank is the obvious solution, but the right charging cable is often missing or gets tangled in your bag. A power bank with a built-in cable elegantly solves this problem. It combines mobile energy with maximum convenience, ensuring you always have the right cable at hand.
This article serves as a guide. We'll explain the key criteria you should consider when making your choice and present a selection of models for various use cases.
The decision for a specific model depends on your individual needs. The following points will help you find the right power bank for your devices and daily life.
Capacity, measured in milliampere-hours (mAh), determines how many times you can charge your devices. A 10,000mAh power bank is a great all-rounder for daily use and can fully charge a modern smartphone like the iPhone 15 about one to two times. For longer trips or charging multiple devices, including a power bank for a laptop, models with 20,000 mAh or more are worth considering.
The power output, specified in watts (W), is crucial for charging speed. A 30W power bank already supports fast charging for many smartphones and tablets. For laptops like a MacBook, a higher output of 65W or more is needed to ensure efficient charging.
The built-in cable should be compatible with your most-used devices. The current standard is USB-C, which is used by most new Android smartphones, the iPhone 15, and many laptops. Some power banks offer additional USB-A or USB-C ports besides the integrated cable to charge multiple devices simultaneously. Check for compatibility to ensure all your devices can be powered.
For mobile use, a compact and lightweight design is a major advantage. A travel power bank should fit easily into a jacket or trouser pocket. Additional features can further enhance user convenience. For example, a magnetic power bank attaches to MagSafe-compatible iPhones and charges them wirelessly, leaving the built-in cable free for other devices. An LED display to check the remaining battery level is also a handy feature.
Based on the criteria above, we have compiled a selection of models that stand out for their functionality and specific features.

The exact number of charge cycles depends on your smartphone's battery capacity and the power bank's efficiency. As a rule of thumb, a 10,000mAh power bank can fully charge a typical modern smartphone (with a ~4,000-5,000 mAh battery) about 1.5 to 2 times. Energy loss during transfer means that the full nominal capacity is not available.
That depends on the power output (watts) of the power bank. Standard power banks with 15-30W are generally not sufficient to charge a laptop efficiently. To use a power bank for a laptop, it should deliver at least 65W of power via a USB-C port. Models like the EcoFlow RAPID with 170W are specifically designed for this purpose.
Bidirectional charging means that one port (usually USB-C) can be used both as an input to charge the power bank itself and as an output to charge other devices. Models with this feature, like the Anker Nano Powerbank, often also allow for fast charging in both directions, which significantly reduces waiting time.
