Full empty starting charging current around 500mA or bit higher, this current will be slowly reduced while charging.

They come from different logic. Normally they start at the same time or shortly after.

But when you turn of the on/off switch, conditioning LED will be off while full LED keep lit as long as UCs are full.

@Ian,

Can I modify UcConditioner from 5V version to 3.3v? For example, change the resistance on UcConditioner?

I found that I bought the wrong version, I should buy two 3.3v. My original plan was to buy the 5V UcConditioner without removing the LDO from McDualXO. However, I forget that McDualXO will automatically skip LDO when the input power is 3.3v so I don't need to remove the LDO on McDualXO.

3.3v UcConditioner powers McDualXO and BUFFALO DAC at the same time, will it have a negative impact? 3.3v UcConditioner powers McDualXO and BUFFALO DAC at the same time If I cannot easily modify UcConditioner from 5V version to 3.3v.

You can, but not that easy. A lot of things need to be changed and I have not time to support.

They are not expensive and for one or two you can try normal letter mail without tracking number for more saving.

3.3v UcConditioner with 3000F ultra capacitor powers McDualXO and BUFFALO DAC at the same time, will it have a negative impact?

I have a friend who works at a power supply company and he can help me. Can you tell me how to modify it?
