Hey. No worries.

Yes. 240v is okay for *mostly* everything I travel with. I haven't tried the immersion heater at 240v. But the most important item I need is my Xiomi USB-C-PD charger, that puts out the needed 20V for my older laptop...

This does take the higher voltage. Since everything else I have can charge off this, I'm good with just an plug adapter, not a voltage converter. Thanks.
