These power strips with surge protection guard against harmful power surges in the home. Nearby lightning strikes, for instance, can cause mains voltages to surge, damaging connected equipment. Even switching on other home electricals - like fluorescent lights with conventional ballasts - can trigger an overvoltage in a home's entire mains system. The AEG PROTECT Basic series of surge protectors offers an effective safeguard against these kinds of voltage spikes.The surge protectors have five outlets for standard grounded power plugs, plus one or two wider-spaced outlets designed to accommodate larger power adapters. The surge protectors include filters to suppress high-frequency interference voltages. To prevent tangled cables, they are also fitted with a cord management bracket at one end. Two LEDs indicate whether the power is on and surge protection is active. The power switch enables the mains supply to connected equipment to be cut off.
