This is a very strong boiler. It accepts about 1L up to the fill line. The lights on the base once you push the lever indicate it is working. Recommend that you watch the pot and remove it at first rolling boil if the surface counter is uneven; or, put maybe 1/4 inch less water to avoid boiling overflow. Always push the lever OFF before removing pot.
I like that I don’t have to use a pot to boil water on the stove for my tea or coffee anymore. Now I can use my new kettle that heats up the water in half the time and it looks cute while doing it <3
