GrnOas.E Power Bank

Why does the power bank make a slight current sound when charging? Is it safe?

Yes, it is 100% safe. During 22.5W Max fast charging, internal components naturally generate a faint high-frequency sound. This is a normal physical trait of high-power chargers and does not affect safety or function.

Why did my phone trigger a foreign object warning or fail to charge? How to fix?

This is a safety trigger from dust, moisture, or a loose connection. Please check/clean ports, ensure the cable is fully plugged in, and retry. Our products are fully safety-certified.
