Monoprice Power & Surge - 12 Outlet Surge Protector Power Strip With 2 Built In 2.1A USB Charger Ports - 6 Feet - White | Cord UL Rated, 3,420 Joules

Protect your electronic equipment from damaging voltage and current spikes with this Monoprice surge protector. This model includes twelve protected power outlets, 4 of which are positioned for AC power adapters, and a 2-port 2.1A USB charger. The clear plastic tabs on the sides of the unit illuminate green to indicate when the surge protector is providing protection to your equipment and when a proper ground is detected. When the protection circuitry has been fully consumed by power and current spikes, the protection light will no longer illuminate, indicating that the surge protector should be replaced. When the grounded tab is not illuminated it indicates that there is a problem with the house wiring and that the ground is not properly connected to the power outlet. The surge protector has 4 keyholes on the back, allowing it to be secured to a wall or other surface.
