Save Electricity in a Crisis: Extend Your Battery and Power Supply

In a crisis, electricity is a limited resource. Setting priorities and minimizing consumption — those are the two most important strategies.

Prioritization: What Needs Power?

Don't treat everything with equal weight. Prioritize:

Priority	Use	Examples
Critical	Communication, light	Phone, flashlight
Important	Heating food	Camping stove (gas, not electric)
Optional	Comfort	Laptop, TV
Expendable	Entertainment	Gaming, streaming

Know the Biggest Power Consumers

What consumes the most:

• Electric heater: 1000-3000 watt — not viable in a crisis
• Kettle: 1500-2000 watt — use briefly, turn off immediately
• Microwave: 800-1200 watt
• Laptop: 45-65 watt
• Phone charging: 5-20 watt
• LED flashlight: 1-5 watt

Conclusion: Phone and flashlight are the most efficient. Replace cooking appliances with gas.

Battery Management

Phone

• Display brightness at minimum
• Turn off WiFi and Bluetooth when not in use
• Close background apps
• Airplane mode when no network — saves 30-50% battery
• Dark theme in app settings (OLED displays save power this way)

Result: 1 day of battery becomes 2-3 days.

Power Bank

• Store in cool, dry place (heat damages lithium batteries)
• Don't discharge below 20% before recharging
• Keep at 70-80% monthly if not used for long periods

Flashlight

• Use lowest brightness setting (often 10x more efficient than maximum)
• AA/AAA alkaline batteries as backup
• Don't run continuously — only when needed

Generate Power Without Grid

Solar: Foldable solar panels (20-40 watt) for €50-100. Charge phone in 2-4 hours with good sunlight.

Crank: Crank radios with USB output — very slow but symbolically important.

Vehicle: 12V socket in car. Run engine 10-15 minutes = several phone charges.

Warmth Without Electric Heating

This is the most critical point in a winter blackout:

• Clothing layers: Thermal underwear, fleece, down jacket — saves more than any heater
• Wool blankets: 2-3 layers, sleeping bag over blanket
• Community: Multiple people in same room share body heat
• Insulate: Seal door gaps, close curtains

Light Strategy

• Headlamp: Hands free, most efficient light use
• Battery LED candles: Ambient light without fire risk
• Tea lights: Warmth + light, but watch for fire hazards
• Emergency blanket as reflector: Reflecting light doubles brightness in one room

Conclusion

In a crisis, you can live comfortably with 10-20 watt daily power consumption. Any medium-sized power bank or solar panel achieves this. The key: prioritize and reduce comfort — for a short time, this is completely manageable.
