The “15 W wireless charging” is the maximum ideal-case number; actual delivered power may be lower depending on alignment, case thickness, phone support, and losses.

When charging multiple devices, the total power output will be shared; if one device draws a lot, others may slow down.

For wired charging (USB-A / USB-C), 22.5 W is the combined (or per-port) maximum as claimed, depending on use.

As with most power banks, expect some energy loss in conversion; you may not get the full 10,000 mAh equivalence into your phone(s).

Ensure the phone is aligned precisely on the magnetic wireless surface for best performance.

The listed safety protections are typical in such devices, but real-world robustness depends on internal build quality.
