I bought a couple of 4F 5,5V supercaps.
They had about 2-3V charge.
I wanted to charge them with a 50mA current limited 5V regulated power supply.
I was surprised to find them going immediately to 5V and have only ~20mA running through them.
Is that OK?
If you got a regulated 5V DC supply, and truly have a limit of 50 mA, then you got to ask yourself..... is it possible for the capacitor voltage (with 3V across it) to abruptly develop 5V? Answer.... nope.
Limiting the current in this case would result in loss of voltage regulation in the power supply.
