Same summary

The Varta Energy 20000 power bank with a capacity of 20,000 mAh offers a reliable solution for multiple charging of phones and other small devices when there is no electrical outlet available. Due to its three USB outputs, it is suitable for users who want to charge several devices at the same time - for example, a phone, headphones or a smartwatch. The device is not designed to charge laptops or fast charge more energy-intensive devices, as data on the output power is not available, so limitations in typical fast charging scenarios must be taken into account.
