Same summary

Sandberg Battery Powerbank 20,000 Survivor, 30W is suitable primarily for users who need a reliable source of power on the go - for smartphones, tablets, laptops and other larger devices. Due to its capacity and 30W output power, it allows charging most modern devices, but for some more demanding laptops with higher power requirements, it may not be sufficient for fast charging. Wireless charging is practical for phones that support this feature, while those looking for an ultra-light and pocket-sized battery will notice a compromise due to the higher capacity and weight. It is suitable for longer trips or working outside the office, where access to sockets is not a given.
