Did I Just fuked My $300 Solo Miner?

I bought a Solo Miner about a month ago, and I think I just fucked it up

I accidentally plugged my laptop charger into it. Saw a spark when I connected it. After that, even with its original charger, it wouldn't turn on.

Took it to a local technician, but since it's imported from China, nobody seems to know how to fix it.

I spent over $300 on this thing, and now I'm wondering if it's completely dead.

Anyone here know how to unfuck this? Is there still hope, or is my miner gone?
