Dear Community, I need a relatively quick answer as I start the RS next Monday and still need a good powerbank. Does anyone know if the 20W one comes with a power supply and/or cable for charging? With the 18W one, you can choose between a powerbank and a powerbank with USB power adapter. With the two powerbanks with 20W, you don't have this option. Unfortunately, I didn't find anything about the scope of delivery in the specs. Merci & best regards
