A hand crank generator is a cute and marvelous device. But, is it really useful or is it an obsolete source of power?
After all, small solar panels are quite affordable nowadays. There are power stations and several types of generators to help you get through power outages. Still, there are people who buy these generators. And they don’t do it to amaze their kids when the lightbulb lights up after you have turned the crank.
So, let’s delve into this and see if these nice devices can actually be helpful.
What Is a Hand Crank Generator?
It is a power generator and you are the power source. By turning the crank, you are turning your muscle power into electrical power. It’s the simplest and the most reliable way to produce power to run or charge your small devices. Yes, it is a rudimentary and a bit cumbersome process, but it can save the day in emergency situations.
What Is It Good For?
Hand crank generators are by no means a necessity. However, if you’re smart, you might consider getting one. Here’s why.
Our society is heavily dependent on power. And so are we as individuals. For most modern amenities there are simple solutions in cases of emergency. Well, if you are prepared, that is. You can store food, find alternative water sources, hunt, fish, grow food… Actually, you can live pretty much sustainably away from civilization. But, the greatest challenge is a possible lack of power. We can survive and even thrive without power, but it’s way more difficult. So, how does a decent prepper or survivalist deal with this?
There are many ways to provide backup power. Gas generators, power banks, solar panels, and windmills are the most common solutions. All these devices are useful and sometimes indispensable. However, none of them can run forever. Sooner or later you may run out of gas. Solar power generators won’t work when it’s raining or at night. Wind generators, well, they don’t work most of the time unless your bug out location is at the top of the windy hill.
So, when you’re out of options, a hand crank generator will come to the rescue. You can use it to recharge your small devices, emergency radio, rechargeable flashlights, or to run some low-wattage kitchen appliances.
Obviously, these generators are no toys and can be very useful. However, it is only a backup, emergency power source. You can’t rely on it for everyday use. It doesn’t produce that much power, and you would need to keep cranking all day long. But, as a backup power source, it is the most reliable one.
What to Look For When Buying One?
You should carefully assess your needs and preferences and look for a matching device. If you need it only to charge your devices on camping trips, you don’t need to go overboard and buy a more expensive and versatile model. On the other hand, if you’re serious about being prepared for a variety of possible disasters, you should look for more powerful models.
Power output is one of the most important features of hand crank generators. It determines which devices you can charge with it. Basically, the stronger it is, the better. However, stronger and more powerful hand crank generators tend to be larger and heavier. You probably don’t want to carry around a heavy and bulky generator, only to recharge your phone or radio. So, there’s a trade-off.
Whether you’re preparing for potentially tough times or you’re an avid hiker or camper, portability is one of the most important things. The more equipment you use, the heavier it gets. Weight slows you down and it’s progressive. Each added pound makes it harder to pack and carry.
So, this is quite simple. You need every piece of your equipment to be as lightweight as possible while still being fully functional.
Modern hand crank generators are pretty efficient when compared with older models. And it’s not just about converting the energy. It’s equally important to be able to keep turning the crank without getting tired too quickly.
Survival or emergency equipment needs to be durable. You want your gear to be reliable when it gets ugly. If it’s not sturdy enough, it might break in harsh conditions. It’s not like you’re going to crank it under the heavy rain or hit it with a hammer, but you probably won’t be able to handle it gently. So, look for sturdy and possibly water-resistant models.
