Using as an micro UPS. Questions...
As I want to connect it (with inserted accu) to USB power and USB device to use it as an micro UPS with my USB device I have such a question:

My situation describtion:
- Accu inserted into ML-102
- ML-102 connected to USB power
- USB-Device connected to ML-102

In case of short power down (few minutes) it will be powered by battery, after power up it will automatically recharche accu and device stay powered.

Question is. In case long power down (few days) when accu will be totally discharged, after powerline UP. Does it automatically power up my USB device ?

maybe not a good idea to leave a battery in this charger all the time

Yes I have read and I will think about that but in any case want to know does it will work as I expected after battery will be descharged as I mention before.

Am I right understand that SKU 1225103 or SKU 1225100 needed to protect ML-102 from overcharging ?

But can anyone confirm In case long power down (few days) when accu will be totally discharged, after powerline UP. Does it automatically power up my USB device ?

Unless your ML-102 is different than this one, yes, SKU 1225103 or SKU 1225100 will be needed to protect the battery, there are better solutions tho.

Yes, it should start charging and outputting as soon as the power come back.

Oops, migh have gave you wrong info on your last question.

Many battery banks do not output while charging, as more electronic componants are needed to isolate the battery from the dc to dc converter input while an alternate current source is providing the power.

Not sure this one can output while charging.

Sorry.
