Overview
- Authorities reiterate stocking food for ten days and at least two liters of drinking water per person per day as the baseline for household resilience.
- BBK checklists call for a flashlight with spare batteries, candles and a lighter, a battery, solar or crank radio, a smartphone with the NINA warning app, a paper list of key contacts, and a charged powerbank.
- Consumer advice shifts to watt‑hours as the key buying metric for portable power, with roughly 65 Wh needed for many laptops and entry powerstations offering about 500 Wh, and cabled charging preferred over wireless to avoid losses.
- The BBK recommends household backup power options including methanol or propane fuel‑cell units and petrol or diesel generators.
- Safety steps include switching off or unplugging major appliances to prevent voltage‑spike damage, leaving a small lamp on to detect restoration, and using the NINA app for cached hazard information when networks fail.
