How long the chrarge hold the anker power bank 10400 in one charge if don’t use

Anker suggests using at least once every 4 months

So I’d say, at least 3 ½ months from fully charged … That’s a guess tho, based on Anker saying to use within 4 months. After that I don’t know, and how it affects the battery if you keep charging n not using?

In my experience with other powerbanks I agree with @MacBlank. I try and cycle through my banks. I prefer not to leave them charged very long or leave them empty for months at a time.
