Checklist
Give the phone a power path that does not depend on the wall outlet
A charged phone is part of the communication plan, not merely a convenience.
When it fits
- The smartphone is the main communication, authentication and information device during an outage.
When to avoid it
- Follow manufacturer and local safety guidance for batteries, generators and vehicle charging.
Checklist
- Backup power source is charged or maintained.
- Correct cable/adapters are stored with it.
- A household member can find it quickly.
- Capacity is tested occasionally rather than assumed.
- Unsafe indoor generator or battery practices are avoided.
Why it matters
Keep at least one practical backup charging method appropriate to your environment: charged power bank, vehicle charging or another safe source. Periodically test cables and battery condition. Store the backup where it can be found in low light or during a rushed departure.
An example
A power bank that has sat empty in a drawer for two years is not a backup plan until it is tested and charged.
Check your result
The primary communication device can survive a plausible local power outage without immediate wall power.
Keep this limit in mind
- Follow manufacturer and local safety guidance for batteries, generators and vehicle charging.
