These gadgets can help in the event of an emergency or natural disaster.
When the power goes out, try the $79 AMPware case.
It has a built in hand crank that generates power for your iPhone 6. Or 6S.
Two minutes of rotating the crank will give enough charge for an emergency call, while ten minutes gives up to two hours of extra battery life.
The crank arm also doubles as a kickstand.
For extra light, the $150 ZeroHour Relic XR flashlight is a compact tactical flashlight that provides up to 1,000 lumens.
Adjust the brightness with the variable control ring.
It's waterproof, and can withstand drops and knocks.
The flashlight also has a battery that can charge USB devices like your phone.
Google's Trusted Contacts is a personal spacey app to show your location with friends and family in the event of an emergency.
It works even if your phone is offline.
At the moment, it's Android only, but an iOS version is coming soon.
