BLACKOUT: The wake-up call from Berlin
What happens if the power suddenly goes off?
A targeted attack on the electricity infrastructure paralyzed large parts of southwest Berlin. Over 45,000 households in Zehlendorf, Steglitz and Wannsee were suddenly left in the dark in the freezing cold - for up to five days.
There was no light, no working heating and no hot water. Supermarkets had to close, ATMs went on strike and the mobile phone network collapsed after just a few hours. What we had previously only known from reports such as the nationwide power outage in Spain and Portugal 2025 now met us in the middle of the German winter.
The events in Berlin show: A blackout is no longer an abstract danger - it is a real scenario that can occur anywhere and at any time.
The facts about the Berlin blackout (Jan. 2026):
The massive power outage in south-west Berlin mercilessly exposed the vulnerability of our modern infrastructure. What was previously considered an abstract scenario became a bitter reality for tens of thousands of people in January 2026.
Dramatic drop in temperature: With outside temperatures of -5 °C, the room temperatures in the affected apartments dropped to just +8 °C off. Without a functioning heating system, your own home quickly became hostile to life.
Duration of the state of emergency: About 120 hours (5 days) the blackout lasted. This meant that Berlin far exceeded the duration of the well-known blackout in Münsterland in 2005 and showed that, in an emergency, state aid takes days to restore the supply.
Infrastructure collapse: Similar to the widespread outage in Spain and Portugal in 2025, not only did light and electricity fail in Berlin, but also mobile phone networks, the water supply in high-rise buildings and all payment systems.
120 hours downtime
In Berlin, it took 5 days for electricity to be restored after the massive power failure. It took a long time for the state to restore the supply in the affected districts.
+8 °C Danger to life
With an outside temperature of -5 °C, the apartments cooled down to +8 °C inside within 48 hours. Without self-sufficient heating, your own home became a life-threatening trap in the middle of winter.
Cold kitchens
Without electricity, conventional stoves would be ineffective. Paradoxically, although the BBK recommends camping gas stoves in guidebooks, it also warns in safety leaflets against their life-threatening use indoors. As a result, many households in Berlin lacked a legally usable way to prepare a hot meal.
A blackout is not just a technical fault - it is a brutal culture shock. While we rely on our networked household in everyday life, the modern home turns into a dark prison without electricity.
From smart home to museum: Who wants a modern 30,000 € Kitchen is suddenly faced with a wall of expensive stainless steel and glass that no longer makes a peep. The Thermomix, the microwave and the networked coffee machine are just silent exhibits. In the midst of high-tech appliances, you suddenly feel Thrown back to the Stone Age.
Caught in the dark: In many modern apartments, the electric shutters to the trap. As they blocked immediately without power, they could neither be opened nor closed. Anyone who had their shutters down at the time of the power cut was suddenly sitting In the middle of the day in complete darkness - unable to let in daylight or see what was happening out in the world.
The failure of the infrastructure: The heat pump remained ice-cold, the fridge began to defrost silently. As darkness sets in early in the afternoon in winter, people sat in their cold, candlelit homes.
Digital emptiness: Without Wi-Fi and mobile networks, all digital services died. What remained was the bitter realization of how dependent we have become on a functioning power socket. No entertainment, no information, no way to distract ourselves.
In this scenario, a warm meal or hot tea becomes the ultimate luxury - and the most important anchor for the psyche.
Standstill in the high-tech home: back to the Stone Age
It's a dangerous contradiction: while almost all the media - citing the Federal Office of Civil Protection (BBK) - mantra-like advise the purchase of camping gas stoves during blackouts like the one in Berlin, they fail to mention the vital small print. The BBK even published its own book entitled „Cooking without electricity“ that advertises these devices as a solution. But anyone who follows this advice in a normal home is putting themselves - and their neighbors - in mortal danger.
Why the „standard recommendation“ becomes a trap:
Deadly danger indoors: While the cookbook provides recipes, the Fire departments and the BBK in their safety flyers at the same time: gas stoves must never be used in closed rooms. There is a risk of carbon monoxide (CO) poisoning - an invisible, odorless gas that kills silently.
The storage ban: In a rented apartment you are legally allowed to maximum two gas cartridges (TRGS 510) - and only in separate rooms. Storage in the cellar or stairwell is strictly prohibited due to the massive risk of explosion. For a 5-day crisis, this is effectively no stockpile.
Multi-family house risk: A single leaking cartridge endangers the entire building. During power cuts, the fire department regularly reports house fires and explosions as desperate people try to keep warm in the kitchen with camping equipment.
The bitter conclusion: If you live in an apartment without a balcony, the official tips leave you on your own. According to the media, you are supposed to use a stove that you are not allowed to use indoors and for which you can hardly (legally) store fuel.
The paradox of official provision
- 100 % Safe: No risk of fire or suffocation as there is no combustion.
- Self-sufficient: Works with just 60 ml of water (including rainwater or industrial water).
- Durable: The heating pads have a shelf life of 5 years and are perfect for crisis preparedness.
- Efficient: Generates hot steam up to 100 °C - without a power socket.
- Safe to use indoors with adequate ventilation.
- Safe storage: Unlike gas, the heating pads are neither explosive nor flammable and can be stored in the home indefinitely."

Focus on safety: your questions, our answers
Why are HEAT.me Lunchbox Kits safer than a gas stove?
In contrast to conventional gas stoves, there is no combustion when using HEAT.me Pads. This means that no life-threatening carbon monoxide (CO) is produced, which can silently cause asphyxiation in closed rooms. There is also no open flame, which massively reduces the risk of house fires in stressful situations.
Can I really store unlimited quantities of HEAT.me Pads in my home?
Yes, while the legal regulations (TRGS 510) limit the storage of gas cartridges in living spaces to a maximum of two, our pads are not subject to these strict explosion protection restrictions. As long as the HEAT.me pads are stored dry in their protective packaging, they are completely inert and safe.
What do I have to consider when operating indoors?
The heating is based on a magnesium reaction in which, in addition to water vapor, small amounts of Hydrogen are created. As hydrogen is lighter than air, it immediately evaporates upwards and outside when the window is tilted. Adequate ventilation is therefore essential.
Are there any specific ignition sources I need to keep away?
Are there any specific ignition sources I need to keep away?
Yes, this is very important: While the HEAT.me pads are active and releasing steam, smoking in the immediate vicinity is not permitted. External ignition sources such as burning candles or lighters must also be kept away, as the hydrogen produced during the reaction is flammable. Once the reaction is complete, there is no longer any risk.
What happens if the HEAT.me pads get wet?
The reaction only starts when the pad comes into deliberate contact with water (approx. 60 ml). If a pad accidentally gets wet, it will immediately begin generating heat. Always store your supplies in a dry place to prevent accidental activation.
Safety is not a coincidence, but the result of preparation
The blackout in Berlin showed all of us how quickly familiar certainties can collapse. But the good news is: you are not helpless in the face of such events. With the right preparation and the HEAT.me Lunchbox Kit, you maintain the security of being able to prepare a hot meal at any time – completely independent of electricity and gas.
Act today to make sure your meals stay hot when it matters most. For your safety, your family, and the peace of mind that comes from being ready for anything.
Your safety matters to us. While the BBK warns against using gas stoves indoors, the HEAT.me Lunchbox Kit offers a clean alternative. When using it inside your home, simply ensure good ventilation (for example, a slightly open window) so that the small amount of hydrogen gas produced by the system can safely dissipate. This way, you can enjoy your hot meal without any risk.
