Two 20,000 mAh power banks: UGREEN Nexode 100 W against Samsung 45 W
Both are 20,000 mAh banks of about 400 g, both print their watt-hours for the airport, and both fast-charge a Samsung phone. The difference is the top port: UGREEN's gives 100 W, enough for a laptop, while Samsung's gives 45 W, a phone figure. UGREEN also tells you how much charge actually comes out and how fast it refills; Samsung does not. Which to buy depends on whether a laptop is in the bag.
