If you have forgotten the password of your WiFi power bank, you can try the following workaround.
First, you can check the instruction manual or the official website of the power bank to determine whether there is a default password. If so, the default password is usually mentioned in the instruction manual. If there is no default password, you can try to restore the power bank to factory Settings.
Usually, the power bank will have a small hole, and you can use a sharp object such as a thin needle or toothpick to hold down the reset button inside the hole for a few seconds until the power bank restarts. This will clear all Settings, including passwords.
If the above methods do not work, it is recommended that you contact the manufacturer or customer support team of the power bank for further assistance and guidance.
Just take off the mobile power and reinstall it
