Same summary

GOOBAY PowerBank 20,000 mAh USB-C 3.0 Quick-Charge is designed as a practical solution for charging phones in various situations - on the go, traveling or during everyday mobility. With a capacity of 20,000 mAh, it covers the needs of users who want to charge their phone multiple times or use it with headphones and a smartwatch at the same time. Due to its size and capacity, it is particularly suitable for those who often do not have access to a socket, but for laptops or more demanding devices it makes sense to check the output power, as this information is not known here. The trade-off of a larger capacity is a slightly higher weight, which may not be ideal for every pocket, but is welcome on longer trips or a longer day in the field.
