Too many times for me! Maybe I should be more gentle with my power leads?!
Anyway I have purchased universal power adapters and the nibs always end up breaking. Finally I found a company who make quality universal power adapters. "Innergie".
I got the mCube 90 and it's never let me down. They even offer lifetime "tip" support and replace damaged or supply new tips upon demand free of charge! (just pay shipping).
Anyway here's some info...
