which step down convertor can I use?

Hi all. I bought a speaker from amazon recently the input voltage is 110v-120v 60hz 900mA. I tried using newstar 300watts stepdown transformer but it blew the transformer fuse. So I'm not sure if I used the correct watt. Please help. Speaker brand Logitech z623. Sorry not enough post count to post photo

as far as I know, speaker need a lot of power.

I had a us dust blower, which already need 500 watt

you needed this type of step down.

Amazon.com: Goldsource STU-1000 Step Up/Down Voltage Transformer Converter - AC 110/220 V - 1000 Watt: Electronics

to be on the safe side always buy higher voltage than what you need.

Hi thanks for the advice! I try out on a 300w converter but it blew my converter fuse. Does that means I really need a 1000w converter?
