A hand-crank generator is a travel device that generates power by turning a pedal or a crank that is attached to the device. The turning creates a mechanical force that helps to create a current that is converted to electricity.
The origin of these devices dates back to the 60s when the military developed portable generators that required an individual to turn the crank to produce electricity.
Things To Consider When Buying A Hand Crank Generator
How much power do you need to charge your devices? This is an important question because the last thing you would want is to buy equipment that does not give you the energy you need. If you have a smartphone, flashlight, and other devices that require charging, you need a hand crank generator.
How much are you willing to spend on the device? This is one of the first questions you have to consider when looking for a hand crank generator. However, you have to keep in mind that the cheaper the gadget is, the fewer its essential features will be.
Therefore, go for the hand crank generator that fits your budget and has the features you need.
People mostly use hand-crank generators while traveling. This means that you may come across harsh conditions. That’s why you need a device that is efficient and can withstand severe weather conditions.
If you are traveling, you should pack devices that are lightweight as carrying heavy and bulky equipment is inconveniencing and tiring. Therefore, go for a generator that is portable but efficient.
Benefits Of Having A Hand Crank Generator
Often, phones and other electronic devices run out of power, and there is no available charging point. This is mostly the case when you are in the woods or other remote areas where it’s impossible to come across a power source.
However, with a hand crank generator, you can charge all your devices at your convenience. Most hand-crank generators also provide you with other essential features such as a radio and flashlight, which can make a massive difference during emergencies.
How Does Hand Crank Generator Work?
Hand-crank generators usually work in a straight-forward way. These devices have an inbuilt dynamo, and the power generating process starts when you turn the crank attached to the device. When you turn the crank, mechanical force is created, which is then converted by the inbuilt dynamo to electrical energy.
The electrical energy created is stored in a battery housed within the hand crank generator.
How Does The Gadget Charge Devices?
Most crank generators have electric sockets where you can plug in to charge any of your electrical devices. However, for a machine to draw power from the hand crank generator, it must have the same voltage and current type.
