Power bank Conditioner or how to keep your power bank alive
I have an Anker Prime 20,000m-Ah power bank that just died. I do not use this very often and when I needed it this last weekend it was dead and wont come back. I understand that these should be discharged and re-charged regularly, but who remembers to do that when it sits in a drawer waiting to be used?
The Anker Prime has a charging base for this power bank that I though could be used as a conditioner, but the descriptions do not indicate anything about that. And it seems that through very little research that these type of batteries cannot be "conditioned" like one might for a car battery that sits for long periods. However, what I understand is that one can burndown a power bank at lest every couple months and and recharge to keep it alive.
So is there, or why is there not a device you can plug a power bank into that does this discharge/recharge cycle automatically so the power bank is always ready to go?
