It provides 15-18 watts via the USB-C port for up to an hour (14.5 watt hour capacity). The iPhone 16 has around a 13 Wh battery, so I would expect it to fully charge it in around an hour (assuming the iPhone 16 can accept the full 15-18 watt charging rate the entire time, many phones will slow down charging around 80% charged. I do not have an iPhone 16 to actually do the test with. It would be able to charge the iPhone 16 a single time before the powerbank would need to be recharged.
@@michalmisio64 I don't recommend wireless charging from a powerbank (as the cable charging is more efficient). It claims it can do the full 15W wireless charging that the iPhone16 supports so that would only be 3 watts slower than the 18w rate I've seen from the cable. [But I don't have an iPhone16 to test this, the only thing I did was verify that the wireless charging worked with my phone.]
