Description
Protect your valuable electronics with the Masterplug Heavy Duty Extension Lead. This black power strip is designed to safeguard your appliances from power surges and spikes. High-draw devices like refrigerators, washing machines, and tumble dryers can cause electrical fluctuations when switching on and off. Over time, these spikes can damage sensitive equipment, but this surge protector provides the defense your home needs. This unit features four standard sockets and two integrated USB ports for convenient charging. The smart USB technology is designed to enter standby mode once your connected device has reached a full charge, making it an efficient choice for your mobile electronics. Safety is a top priority with the included thermal cut-out indicator. This feature provides clear peace of mind by letting you know that your connected appliances and electrical equipment are actively protected. If the surge protection operational indicator is not illuminated, you will know it is time to check the unit. With a 2-metre cable, this extension lead offers the flexibility required for various household or office setups.
