I'm reaching out regarding a power bank I own that I plan to use with a mobile router in my car while traveling. I've noticed that the power bank tends to switch off after a short period of inactivity, which can be quite inconvenient during my trips. Could you please provide some guidance on how to keep the power bank running continuously while connected to the router? Are there any specific settings or changes I should consider to prevent it from automatically shutting off? Your assistance would be greatly appreciated!
