Problem with laptop charging adapter

I have a Toshiba laptop and a few days ago the laptop adapter went bust and stopped working at all. I have looked in the local shops but no one seems to have the correct adapter for the laptop.
I have seen a similar looking adapter which is actually for another model, the DC output and amps are the same, would this work for my laptop?

If not then where can I get the correct adapter from?

I would recommend using another model adapter, it may cause problems to the laptop. You can try getting the correct laptop online or even ask at the shop where you brought your laptop from. Even try a better place, it is not always necessary that whatever the local shops have is only available in the market, the better or say poshers the places the better variety and range of products.
