Hello @mrhrd and welcome to the forum.
You would not happen to have any further information? Who makes it, what is the model name. Anything helpful you can think of to identify the part you are looking for would be rather welcome.
For someone who is not in the same room as you it is rather hard to try to guess what you have in mind. If you can take the guesswork out of it then this helps helping.
To be honest, I don’t have the exact brand or model name because it is a generic, unbranded mini UPS. The picture shows all the information I have: a 12V 2A power supply with a 5400mAh battery capacity.
The reason I am looking for this is for my smart door project. I am using this mini UPS to provide backup power to a 12V solenoid lock in case of a power outage.
Because of this, I don’t need the exact model. I am basically just looking for a generic Fritzing part that looks physically similar (a power adapter box) and has standard DC output connections (like a barrel jack or VCC/GND wires) so I can connect it to my relay module in the schematic.
