24 in. Power Strip Provides 4 AC Outlets and 4 USB-A Charging Ports Compatible with standard electrical equipment, this UL-listed power strip has a 24-inch aluminum housing with a durable black finish. There are a total of four NEMA 5-15R outlets and four USB-A charging ports; each one-foot section has two outlets and two charging ports. The outlets are placed at a right angle to prevent connected power cords from blocking access to the adjacent outlet. In the event of an overload, a 15-amp resettable circuit breaker immediately shuts down the power strip to prevent equipment damage. Charge Up to 4 Mobile Devices with 6.2A of Shared Power In addition to AC outlets, this power strip provides USB charging for up to four mobile devices, including tablets, e-readers and smartphones. Each pair of USB-A charging ports provides up to 3.1 amps of shared power. The USB ports eliminate the need for AC adapters for charging cords, leaving outlets available for AC equipment. Place Outlets and Charging Ports Away from the Power Source The PSC240410USBB has a 10-foot cord, so you can mount it away from its AC wall outlet or other power source. The cord has a NEMA 5-15P plug. Use Optional Mounting Clamps to Add Flexibility to Horizontal Installations If drilling mounting holes is not possible or desirable, use the included heavy-duty C-clamps to mount the power strip. The clamps attach to the edge of a desk, table, workbench or other solid, flat surface up to 2.25 inches thick. Slide the clamps onto the edge of your surface, hand tighten the adjustment knobs and snap the power strip into the built-in mounting clips. No drilling is required. It is easy to relocate the installation because there are no fasteners to remove. The PSC240410USBB also comes with clips for vertical or horizontal surface-mounting to a wall or workbench.
