Question Charger of Toshiba Portégé Z30-A1302 laptop?

[Techask]

What is the size of the connector pin of the charger is it 5.5 x 2.5mm? I’m planning to buy online but it is risky if it doesn’t fit in my laptop. Is it okay to buy different model number of the charger but same specifications like 19V and 2.37A?

Do a search online for your laptop model charger, if it states it's for your model then it's safe to get.
