Core X and Chroma Input voltages

Hi! Been looking at getting a Razer Core X to take my laptop to the next level. Silly question, but in the specifications, the input voltages aren’t listed; can it be used internationally? I sometimes travel long term outside the US and would like to take it with me. I know these days most PSU’s worth anything are rated for 110-240 V, but I figured asking the question isn’t a bad things to do. While I’m at it, may as well know if the Chroma also has universal input voltage as well.
