I wanted a new powerbank, to add to the ones I have which are probably no longer as powerful as they once were.
After much deliberation (and making the guy working in the shop sneeze đđ€§) I bought the following:
1x powerbanks a 10000mAh
2x powerbanks a 20000mAh
1x miniature charger (with USB-C output, supposedly upto 20W)
1x USB-C to USB-C cable
