Can the power supply be delivered with Eu plug?

Hi, There is EU plug for the power supply, please order from EU amazon, https://www.amazon.de/Geekworm-100-240V-Surveillance-Amplifier-Raspberry/dp/B0BD81W6SN best regards. Geekworm Team

Will this work with a 7500 mAh lithium battery?

If your battery has a USB-C type connector for charging, and your battery has the built in charge controller (nearly 100% of these portable batteries do) you should be able to use this as a very capable charger for it. I use mine for running Raspberry Pi computers
