Power outage kit

As I was looking at my electric bill today, I noticed a page on being prepared for a power outage. Look here for details: https://www.idahopower.com/outages/beprepared.cfm 

And here's their suggested kit:

Outage Kit

1. Matches
2. A flashlight
3. Extra blankets
4. A battery-powered radio
5. Batteries
6. Bottled water
7. Canned and dried foods
8. A manual can opener
9. A wind-up clock or battery-powered clock
10. A telephone that doesn't depend on electricity

I'll need to check and be sure I have all of these in our 72 hour kit. 

I'm not sure about #9 & 10
