Emergencies always happen unexpectedly. Random power company blackouts, natural disasters (hurricanes, earthquakes, etc.), outdoor activities (camping, hunting, etc.) and vehicle breakdown will cause us experience darkness. All the human beings are accustomed to being lighted in the darkness now. Sudden darkness might cause fear, accidents or other miseries. Preparing for darkness, in my opinion, is necessary and not a kind of waste. Emergency flashlights are a must have tool for these situations.
Usually, flashlights used for emergency include Portable Flashlights for Everyday Bringing, Power Failure Rechargeable Flashlights, Solar and Dynamo Hand-Crank Emergency Flashlights and Shaker and Squeeze Dynamo Flashlights.
Portable types fit into purses or on key chains, easy for you to carry one anywhere you want, everyday. Usually run on AA and AAA batteries, they could offer you light for tens of hours.
Power Failure Rechargeable Flashlights
This type is designed for home use. When the power is off unexpectedly, the flashlight automatically turns on. They are usually rechargeable. Some types even could be used as a nightlight when they directly plug in electrical socket.
Solar and Dynamo Hand-Crank Emergency Flashlights
This kind depends on rechargeable batteries for its running, designed for extended use with no access to any extra outside supplies. Having no moving parts, solar flashlights are more reliable while they don't give a good performance in storms and other limited sunlight conditions. Hand cranks offer 10 to 60 minute-light for each time of cranking, however, they require user to continuous turn for its running. Some types are combined with a compass, radio, laser pointer, whistle or siren, offering all-in-one versatility.
Shaker and Squeeze Dynamo Flashlights
These flashlights are powered by squeezing or shaking. They are usually small and light. You could use one hand for its operation. Shaker flashlights could be water-resistant, as they could be completely sealed. However, they are less powerful than other types.
Candles and matches are also good light source for emergency. They are long lasting and more reliable than battery powered flashlights.
No matter what kind of emergency flashlight you choose, don't forget to test the practicality and reliability. What should include your test include battery life, the brightness, the durability and charging capability.
