Capacity is only half the story – 10,000 mAh fills a phone about twice, but if the output is low it takes hours. Newer models offer 20–65 W fast charging, a magnetic Qi2 or MagSafe attachment to the back of the phone, and a USB-C cable built into the body, so there is no separate lead to carry. If it is coming on a flight, check the Wh figure, because cabin baggage has a limit on it.
