Enjoy Clutter-Free Power Anywhere
6-in-1
Power up your mobile devices and multiple appliances at the same time thanks to 3 AC outlets, 2 USB-A ports, and 1 USB-C port.
Clutter-Free Charging

A compact design and a 5 ft power cord mean you can easily move this power strip around your room until you find the perfect place.
