Overview

About the Tripp Lite Protect It! TLP366CUBEUSBB

Compact Cube-Shaped 3-Outlet Surge Protector with USB Safeguards Your Electronics

Ideal for your home or office workstation, this Protect It!® three-outlet power cube features a surge protection rating of 540 joules to defend your sensitive electronic components against strong power surges and spikes. Because residential power outlets have three wires-hot line (H), neutral (N) and ground (G)-the TLP366CUBEUSBB protects all three, covering the two protection modes: full normal mode (H-N) and common mode (N-G/H-G). The three-inch cube is perfectly sized to fit inconspicuously into your workspace or take with you to the office, dorm, hotel or conference room.

3 NEMA 5-15R Outlets Accept a Wide Range of Electronic Devices

The power cube works as a complete unit or can be split into two, so you can leave one portion at your desk and use the other for travel. The bottom portion contains three NEMA 5-15R outlets for powering your PC, printer, wireless router, game console, television or other home/office electronics. Each outlet is located apart from the others to accommodate bulky power transformers.

6 USB-A Ports Keep Your Mobile Devices Charged to Capacity

The top portion features four USB ports that share 4.8A for charging your smartphone, tablet and other USB mobile devices. The bottom portion, in addition to three NEMA 5-15R outlets (see above), has two USB ports that share 2.4A. The ability to charge up to six mobile devices at the same time makes the TLP366CUBEUSBB vital for busy families. Plus, the ability to split the power cube into two separate units means you can take one with you for instant charging on the road.

Premium Protection from EMI/RFI Line Noise Helps Your Equipment Perform Better

Various electromagnetic and radio sources found in virtually every home and business can cause disruptive interference on the AC line. Known as EMI (electromagnetic interference) and RFI (radio frequency interference), this line noise is a common cause of performance problems. This surge protector filters out disruptive line noise that can disturb your electronics and inflict hardware damage or data loss. This EMI/RFI filtering also helps your connected components perform better and last longer.

Includes the Latest Safety Features to Maintain Your Equipment's Well-Being

Automatic shutoff permanently cuts power to outlets if the protection circuit is incapacitated, preventing equipment damage and indicating replacement is required. A green LED confirms your connected equipment is protected.

Use the Power Cube as One Component or Split It into Two

The removable top portion with four USB ports includes a NEMA 1-15P plug, so you can take it on the road separately for charging mobile devices at school, in the airport and at the hotel. The plug folds into the unit to shield it from damage and prevent it from snagging or scratching your bag's contents. The cube's bottom portion has a six-foot pivoting power cord and space-saving right-angle NEMA 5-15P plug, which helps you connect to a wall outlet located behind furniture placed flush against the wall.
