Kind of Urgent - I need a power converter to plug in my USA devices in Peru

This is mainly for my work laptop, but my 3DS and possibly Switch will also get charged this way. What do I need to buy? I’m assuming a full step up converter is necessary. But most of the ones I’m seeing plug into US outlets because they are powered devices. Any suggestions?

A quick Google says the local hardware store ferretería will have what you need - voltage converter, one with built in USB would be ideal.

Switch chargers (and all Apple chargers if you’re using a mac) are worldwide 100-240V 50-60Hz, you only need to adjust the plug shape via a $2 converter.

I’m sure they’ll be available at the Peruvian airport for a bit of a premium.
