Same summary

The Sandberg Battery 20,000 88W Powerbank is designed for users who need a reliable solution for powering laptops and other electronic devices on the go. Due to its high capacity and wired connection, it is especially suitable for those who often use larger or more demanding devices, such as laptops, tablets or phones with the ability to charge quickly. At the same time, due to its larger capacity, it is slightly less practical for everyday pocket carrying, but allows the user to charge multiple times without worrying about running out of power after just one cycle.

With an output power of 88W, the power is high enough for most laptops, but we recommend that you check the requirements of your device before use - some more powerful laptops require even higher power.
