It features a surge protection rating of 1,080 Joules to defend your sensitive electronic components against power surges and spikes. This portable surge protector features a spring-loaded clamp that attaches to any flat, smooth surface up to 2.5 in. thick, so you can take it with you to the office, dorm, conference room, hotel or anywhere else you need to plug in your electronic devices. This surge protector with 3 USB ports is ideal for keeping your devices at full capacity. 2 USB-A ports share 2.4 amps for charging your smartphone, tablet and other USB mobile devices, which are also protected from the damaging effects of surges, spikes and line interference. In addition to the dual USB-A ports, a 3 amp USB-C port charges devices quickly and safely. 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. So 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 with longer lifespans. The lighted on/off switch provides 1 touch control over connected equipment. Automatic shutoff permanently cuts power to outlets if protection circuit is incapacitated, preventing equipment damage and indicating replacement is required. A green LED confirms your connected equipment is protected.
