No using a power source that can supply more than the phone needs is not harmful, because the charger is actually inside the phone, and it regulates the charge rate; the external power source does not.

Not as light as some portable panels. The FlexSolar 40W is a high-output, easy-to-use charger that can quickly unfold from the size of a large book into six linked solar panels. This medium-capacity panel has a DC output that can charge portable power stations, as well as USB-C and USB-A outputs for smaller devices. The Apple 30W USB‑C Power Adapter offers fast, efficient charging at home, in the office, or on the go. While the power adapter is compatible with any USB‑C device, Apple recommends using it with MacBook Air. You can also pair it with select iPhone and iPad Pro models to take advantage of the fast-charging feature. M6fCU. 306 376 166 167 160 333 489 194 186
