/diy/ - Do It Yourself

Dingus is need of help here, had a power surge during a storm last night. The ac adapter on the left stopped working, I'm hoping the cell phone booster I had it plugged into is okay.
I ran to walmart and grabbed this variable voltage ac adapter on the right. None of the connectors fit my device because standardization is for plebs. Since my old adapter is trash could I splice the end and insert the wires into the two holes you see there? Would it work? Is it safe? It would only be temporary. I just want to know my device still works before ordering the new adapter.
Yes I will use a surge protector next time.
