Anker Nano Travel Adapter, 5-Port Power Adapter with 1× 2-Pin AC, 2 USB A, 2 USB C for 20W, Smart Temperature Control, Works in 200+ Countries, Not a Voltage Converter, Travel Essentials (1-Pack)

Here ya go: https://www.amazon.com/dp/B0DHVNPN7J. If we're talking about a straight up voltage converter (240 to 120, etc), I never travel with those - almost all devices anyone needs handle that in their own power supplies. But what I listed plus this https://www.amazon.com/dp/B0F8VLDPPW make for a killer fairly small charging setup that handles more than everything that I (or anyone, unless they are actively gaming on a laptop with a beefy video card) need.
