SURGE PROTECTION WITH ONE SOCKET AND TWO USB PORTS Protect small electronics from dangerous surges and spikes with Belkin's SurgeCube surge protector with one outlet and two USB ports. All you need to do is plug the surge protector into a power outlet and connect your devices to protect them from power surges, lightning strikes, and line power contamination. Built with high-quality circuitry and premium absorbent materials to protect your devices and data, Belkin's SurgeCube is perfect for laptops, basic home appliances and smaller kitchen appliances. PROVIDES PROTECTION AGAINST VOLTAGE SPIKES AND Fluctuations When your electronic devices are connected to Belkin's SurgeCube, they are protected from unexpected power surges caused by short circuits and lightning strikes. The SurgeCube also protects your devices from sudden voltage fluctuations or minor voltage spikes and sags that can cause damage to your devices over time.TWO 2.4A USB PORTS FOR CHARGING Quickly charge portable devices via two built-in USB ports and protect them from damage and data loss. Because these USB ports are 2.4A, devices can be charged faster than traditional USB ports and are also better protected. They are therefore perfect for smartphones and tablets. SURGE PROTECTION FOR UP TO 306 JOULES Designed to withstand up to 306 joules, the surge protector provides your small electronic devices with protection from voltage fluctuations, surges and spikes that can cause damage. The particularly large metal oxide varistors (MOVs) absorb excess energy and release it as heat. A fiberglass protective layer on the metal oxide varistors suppresses or smothers fire should a high overvoltage trigger the metal oxide varistors to ignite. COMPREHENSIVE THREE-WIRE PROTECTION Belkin's SurgeCube provides three-wire protection for your devices. This means that they are protected from overvoltages that can occur between phase, neutral and earth conductors.
