Hello,
The powerbank is only compatible with the Galaxy A7 (2018) to a limited extent. The smartphone cannot be charged inductively and does not have a fast charging function. This means it does not charge with 25 W. It also has a micro-USB port. To connect it to the powerbank, you would therefore need an additional cable from this to the USB-C port.

Yes, that works, but only if the A7 also has wireless charging, only then could you charge it with this powerbank. However, this powerbank is very expensive, but a model with wireless charging that also has additional ports (not just USB-C) would be this model, for example:

Varta Wireless Power Bank + Charging Cable (15000 mAh, 20 W)
