The roku device can use an outlet or usb port. It also makes it possible for me to not carry multiple adapters, as this has direct usb plugins. Used to replace a much larger power strip and additional usb charger.

This device isn't ul certified, which doesn't inspire confidence. The usb ports are severely underpowered. Complaints from my device of insufficient charging power.

This extension cord cube is sturdier, thicker, and heavier than most. It is a little thicker than i expected. It's really nice and has more sockets for me to plug into.

It fits nicely in my carry-on luggage, but it is a bit too thick for my laptop bag. Saves a ton of space.

This item has a plastic bottom that easily slips off anything you set it on. It is very large and heavy not for travel.
