Plug in the laptop on the train. Can it be done?

I noticed for the first time today that on the Tz Chiang train, the express, the cars have an outlet behind seat 48 in every car on some trains. The outlet is labeled for the vacuum cleaner, 110V, 1kW. It has two flat holes and a round ground. I’m wondering. Can I plug my laptop into that directly? Or do I need a converter of some kind? If the latter, where can I get it? Has anyone used those outlets?
