Although my zip code often changes, the need to keep all my gadgets powered up does not, and wall outlets can sometimes be fleeting. Packing an extension cord is one way I navigate travel uncertainty.I used to travel with an individual charging cord and adapter for each device until five years ago, when I realized the value of packing lighter. Watching YouTube travel vloggers showed me I could save time (no checked bags) and take up less space by avoiding clutter. When I saw one vlogger talk about the practicality of using an extension cord, I made the switch, and haven't looked back since.Several extension cords have made it into my bag over the years, but my current go-to is the Anker 321 power strip. Here's why this $15.99 (38% off right now) extension cord makes it into my carry-on every time.

I use gadgets with several different charging ports, including USB, USB-C, lightning, and more. I like the Anker 321 power strip because it has plugs for multiple cord adapters.This 20W fast-charging extension cord has a USB-C port, three outlets, and USB-C charging for Apple and other USB-C devices. It's five feet long, enough to plug in anywhere I'm staying without feeling restricted. I power up all my devices from one place and enjoy traveling lighter.Of course, if you can't plug this extension cord into the wall in your destination country, it won't do much good. For that, consider also getting a power adapter that will work for many countries. The one I use is the EPICKA universal travel adapter ($49.99).Small enough to fit into all of my travel bagsThe adapter kit and extension cord don't add much weight to your travel backpack. The combination of the extension cord and adapters has ensured I can work as I travel, watch entertainment on my devices, and stay connected to my kids back in the United States.The Anker 321 power strip is light; it fits in my laptop, backpack, or carry-on. Most of the time, I have it in my laptop bag for easy access and quick charging. I like that I can fit it in any of my travel bags without worrying about it weighing them down.An extension cord is not a common travel item, but it should be. Traveling with one power source that can power multiple gadgets helps declutter your travel bags, and fewer outlets are needed in the places where you’re staying.If you're going on an adventure this year, consider picking up this underappreciated convenience so you can keep everything charged up as you travel.
