poor power adaptor

I love my BB pedal and it built like a tank, but by contrast it’s power adaptor seems very poor quality. Especially
the cord seeems like thin and fragile. But it has particular power capability and plug. I’m afraid that it can harm my beloved pedal, cause it fits not too perfectly in the power outlet. Can you recommend me the better solution, or can I change it to another, stronger adaptor and replace the plug, which is specific. Honestly the original one is not for everyday and stage using. Sometimes it lost the power and my BB stoped during practice or in worse case during a gig. I got europian type one.
