They jack up the voltage. Which I’m guessing that’s what the keyboard/computer use to report “charge”. If there is no current draw then it seems fine. Put a load on it and it will go down just the same. TANSYAAFL.

True, but in many circuits, that load might be measured in microamps. What might be a problem would be, for example, a temporary need for extra power (like Bluetooth transmission when most of the time it receives). A capacitor will help but it can’t perform a miracle.
