Surge Protector with USB Charging Safeguards Your Sensitive Electronics Ideal for your home or office workstation or home theater, this Protect It!® single-outlet surge protector features a surge suppression rating of 450 joules to defend your sensitive electronic components against even the strongest power surges and spikes. Because residential power outlets have three wires—hot line (H), neutral (N) and ground (G)—the TLP104USB protects all three, covering the two protection modes: full normal mode (H-N) and common mode (N-G/H-G). A green LED confirms your connected equipment is protected. NEMA 5-15R Outlet Accepts a Wide Range of Electronic Devices The NEMA 5-15R outlet is set apart on top of the surge protector to accept a bulky transformer without blocking the USB ports. Plug your PC, printer, wireless router, game console, television, sound system or other home/office device into the outlet for protection against dangerous surges, spikes and line noise. 2 USB Ports Share 2.1 Amps of Charging Power Two USB-A ports are available for charging your smartphone, tablet or other USB mobile devices. They share 2.1A for charging multiple devices at the same time. 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. Versatile Surge Protector Provides Multiple Installation Options This surge protector with four-foot cord and space-saving right-angle NEMA 5-15P plug allows you flexibility in placing the unit behind furniture or other tight places.
