Keeping a Power Bank plugged in

[skstrials]

If I were to keep a power bank plugged in, and use it to charge my phone through it overnight too, would that kill the power bank prematurely?

The reason is that I do not always need to take a power bank out, but for the few times I need it, I would like a fully charged power bank. And I might not always plan ahead to charge the power bank in advance.

Not a lot of impact there, once the phone is at 100% it'll just trickle charge.
