Problem to be solved
The problem that the battery is not charged because it is not connected to the root of the battery, even though it is supposed to be charged.
I forget to put the cable back in when I'm switching cables depending on what I'm charging.
The problem of bringing a mobile battery but not having the proper cables
It's easy to get careless with a variety of cables.
solution
Buy two of these and keep one in your bag at all times.
The other is always plugged into the charger (USB-A) by the desk.
