Beautiful end table that works well anywhere.
Color: Black, Number of Items: 1
The JUSTOGO end table immediately stands out thanks to its unique, modern design and practical features. Its rectangular shape makes it surprisingly versatile. You can position it to showcase the three open shelves for easy access and display, or use it as a narrower separation piece or traditional end table. That flexibility makes it adaptable to different rooms and layouts.
One of the most thoughtful design choices is the placement of the built-in USB ports and power outlets. Located on the middle shelf, they don’t crowd the tabletop and still remain easily accessible for charging devices. This keeps the top surface clean and fully usable while ensuring cords aren’t stretched too far.
The black finish is another plus. It’s neutral, clean-looking, and blends easily with a wide range of décor styles.
If there’s a downside, it’s the assembly process. The instructions could be clearer, and while the advertised setup time is 20 minutes, it realistically takes closer to 40. That said, assembly is a one-time task, and once it’s complete, you’re left with a sturdy, functional, and visually appealing piece of furniture. Overall, it’s a smart combination of style and utility.

Perfect solution
Size: 20FT, Color: White
Incredible value - solves our phone charging needs without bulky chargers attached to traditional extension cords… aesthetically superior with outlet cover and flat cord that we plan to conceal between tiles. A+

Great Extension Cord for hard to reach places.
Size: 5FT, Color: White
Wasn't sure if I would like this or not but I really do. We have the stand up version (not by same vendor) but really liking this smaller version that I was able to stand on edge and not take up valuable room on my side table. We used it for the outlet under the bed to the bedside table. Has enough power to run multiple items with no issues. I like that it comes with USB, C, 2 prong, 3 prong. I didn't use the included cover but that was because we had something else plugged into the other socket.
