Same summary

The Sandberg Powerbank USB-C PD 20W 10000 mAh portable battery is primarily a sensible choice for users who want reliable backup power for their phone or smaller devices during daily mobility, travel or longer errands. The 10000 mAh capacity allows for practical carrying in your pocket, while providing enough energy for multiple phone or headphone charges, which covers the most common needs of urban users and students. With support for fast charging via a 20 W USB-C output, it is also suitable if speed is important to you when charging, but it will not be able to effectively charge larger laptops or devices with more demanding consumption. The model is wired and therefore universal, but if you are looking for wireless or MagSafe charging, it is not the best fit for this purpose.
