Charging isn't just something you have to do at home, that's why they make portable chargers/battery packs and super-small wall warts. But sometimes, you can't be sure where you'll get your power — not just in terms of which coffee shop or hotel you'll plug in at, but which country. If you travel a lot for work, you're used to the added complexity that travel adapters impose, but with a compact design thanks to gallium nitride, one 30W USB-C port, and three USB-A ports, Zendure's Passport Go might save some space in your rollaboard. It's a decent value at $39 right now, but it's set to get more expensive later.
