When a thunderstorm rolls in, it’s not just the lightning that poses a threat — electrical surges can wreak havoc on your home electronics. Taking a few precautionary steps can help protect your expensive appliances and valuable data.
1. Devices You Should Unplug Immediately
– TV and Internet Router
– These are highly sensitive to electrical surges.
– Even when switched off, they can still be damaged or permanently fried by sudden voltage spikes.
– Computers and Printers
– Fragile electronic components inside make these devices especially vulnerable.
– Save your important files regularly and unplug them when there’s a risk of storm-related power fluctuations.
– Sensitive Appliances (Microwave, Washing Machine, Dishwasher)
– A lightning strike or power surge can cause serious internal damage, leading to expensive repairs or full replacements.
– Phone and Laptop Chargers
– Small but dangerous — leaving chargers plugged in during a storm can cause overheating or even electrical fires due to surge impact.
2. Devices That Can Stay Plugged In
– Non-electronic Items (e.g., classic lamps)
– If it doesn’t have a circuit board or digital controls, it’s generally safe.
– Basic lamps with standard bulbs are low-risk during a storm.
– Fridge or Freezer
– These can remain plugged in, but it’s strongly recommended to use a surge-protected power strip to minimize risk while keeping your food safe.
3. Bonus Tip: Long-Term Protection
For permanent protection, install a surge-protecting power strip or have a surge protector fitted at your main electrical panel. This provides broader security against unexpected voltage fluctuations throughout the entire home.
