If you plug any electronic component or device directly into the wall, you leave it vulnerable to dangerous power surges and spikes. That's true of audio/video equipment, but also your phone and tablet. The Panamax Power360 shields each piece of gear in your home theater system and protects your charging mobile devices.You get eight protected AC outlets, a telephone line input/output, and a set of coaxial input/output jacks for your cable TV or antenna connections. Also, two detachable USB modules are included with 6-foot cables giving you flexibility while you safely charge your phone or tablet. There are four protected, high-capacity USB charging ports in all.When a catastrophic power spike hits, like from a lightning strike, the P360-8's Protect or Disconnect circuitry reacts in less than a nanosecond, instantly switching off power to your equipment. Then it automatically resets itself when voltage returns to normal. Panamax's SmartGuard feature provides similar protection when under-voltage (brownout) or over-voltage conditions exist. Power to your gear is automatically disconnected until voltage returns to safe levels.
