Crank LED flashlights do not require external power and neither do they need batteries. These flashlights represent the latest technologies in this segment and are powered solely by muscle strength. In emergency situations, where there may not be batteries or electricity to charge the flashlight, these crank LED devices are the perfect solution.
Hand Cranks
The hand crank LED flashlights are quite popular on the market these days. These flashlights have a handle, which can be winded to produce power. Alternatively, instead of the crank, the flashlight could contain linear generators, which trigger once the user starts shaking the flashlight. This energy gets stored within a capacitor or battery which can then be used to power the flashlight. The older flashlights were revolutionary in design but now with LED´s being used for the bulbs, they have become a lot brighter whilst becoming even more efficient. Some flashlights, of a similar design use flywheels for energy storage, and while these designs are quite archaic, the most modern versions are more useful and functional.
More Energy Faster!
The crank LED flashlights are a combination of previous technologies and the power of LED bulbs. These flashlights with hand-crank mechanisms now deliver higher energy quicker, in the events that they are needed in a hurry. Just a single minute of cranking can facilitate an entire hour of lumen output. Hence, it is easy to power these flashlights with just 15 seconds cranking. This kind of high output is only possible when LEDs are used instead of the conventional incandescent bulbs. With very bright light, high efficiency and no burn outs, these flashlights are the trusted choice these days.
Different Options
The new range of crank LED flashlights comes with a variety of options for users to select from. These flashlights have been designed keeping in mind the specific needs of the discerning survivalist or camper. The most modern crank flashlights even come with a radio and while this isnt specific to survival requirements; it could certainly make being stuck in the wild more pleasant on occasion. Some flashlights such as the ElectriLite 5 LED Crank Flashlight also function to charge phone and USB devices, thereby providing a dual utility. Should the cell phone battery die out, these LED crank flashlights will help out. The ability to charge USB ports would also facilitate charging many other items. All these small thoughtful design elements make these flashlights worth every penny.
The best thing about the crank LED flashlights is that they come in small sizes. This makes it easy to carry them around. When hunting or on a camping trip, its easy to pack these flashlights into a backpack. After all, you never know when youd need to light up the pathway or charge up a dying cell phone. The crank flashlights are all the rage these days and rightly so. With their excellent performance, dual functionalities as phone chargers and flashlights as well as high levels of bright light, they are indispensable especially in circumstances when purchasing batteries is not an option.
