Searches for "cyber attack fridge" and "freezer cyber attack" have risen sharply in Malaysia since 3 November. It is easy to see why. In Parliament that day, the Prime Minister noted that the European Union, Canada and Japan had advised their citizens to keep food stocks, and said the government is strengthening protection for strategic sectors, including energy and food supply.

A fridge is the appliance most households worry about in a power outage, because the loss is real money and real waste. The good news is that it is also one of the easiest things to protect.

How long food stays safe without power

The US government's food-safety guidance is a useful rule of thumb. An unopened refrigerator keeps food safe for about 4 hours. A full freezer holds its temperature for about 48 hours, and a half-full one for about 24, as long as the door stays closed. Malaysian kitchens are warmer than most, so treat those as the upper limit, not the target.

• Keep the doors shut. Every opening lets the cold out.
• Keep the freezer full. Frozen bottles of water fill the gaps and act as ice packs.
• Keep a fridge thermometer. The fridge should stay at 4°C or below.
• When in doubt, throw it out. Never taste food to check whether it is safe.

Running a fridge from a power station

A household fridge does not draw its full power all the time: the compressor cycles on and off. The easiest way to size it is the energy label. A fridge rated at 400kWh a year uses about 1.1kWh a day.

The fridge alone, with about 85% of rated capacity reaching it. A fridge briefly draws several times its running power when the compressor starts; these three models have the output for a household fridge (1800W and up), while a small RIVER-class unit may not.

Leave the fridge plugged into the power station all the time and it becomes a UPS: DELTA 3 Plus and DELTA 3 Max Plus switch to battery in 10 ms, so the fridge never notices the power cut.

A portable fridge freezer for the essentials

GLACIER Classic is a portable fridge freezer, in 35, 45 and 55 litre sizes, that runs from the wall, the car or its optional plug-in battery (298Wh). On that battery, EcoFlow rates it to hold 4°C for up to 43 hours (35L model, 25°C room, Eco mode). It also charges from a 110W solar panel.

It is a practical backup for the things that matter most if the kitchen fridge has to go off: milk, baby food, and any medicine that needs to be kept cold. It also earns its place on road trips and at the campsite for the rest of the year.

Supermarkets, payments and a sensible food plan

If a cyberattack ever disrupted card payments or online banking, the shops might be open but hard to pay at. On 3 November, the Bank Negara Malaysia governor held a special session with financial institutions. You do not need to stockpile, but a few habits make sense:

• Keep some cash at home, in small notes.
• Keep a week of non-perishable food you actually eat: rice, tinned fish, instant noodles, biscuits, UHT milk.
• Rotate it into normal meals, so nothing expires.
• Keep a few days of drinking water.

It is ordinary household sense, and it covers a flood or a long holiday closure just as well.
