We are familiar with a wide range of solar-based portable power systems for off-grid power. What about a cool non-solar, non-wind, and human-powered solution for off-grid power?
Yes, that is what the crank power is. We have some impressive crank- and pedal-powered off-grid power systems for the production of human-generated power.
Here is our list of the best hand-crank and pedal generators. Also known as, human power generators, these crank- or pedal-based systems are ideal emergency power backup solutions.
Are you wondering how a hand crank or a pedal generator works?
It works on very simple technology. A crank power generator comes with a dynamo and a manual way to rotate it to produce power. It can be either a pedal or a cranking lever.
Obviously, such a system doesn’t require sunlight or any other natural energy sources. You can produce emergency power to charge your handsets in survival situations. Of course, power from such an off-grid power system can even be your lifesaver, though the output volume is very limited.

Human Power Generator Vs Solar Vs Wind Vs Hydropower
These are all the cool candidates for green power. Here, let us see how human power differs from other sources of green energy. Solar, wind, and hydropower are natural sources of energy that are wasted if not utilized.
We have solar panels and wind turbines to produce power from the solar and wind sources, respectively. Meanwhile, hydropower is somewhat different, as it requires an expensive and climate-impacting dam across a river.
The limitation of all the sources is that each has a prerequisite for the availability of power. Solar energy can be collected only under a bright sun, which happens only between 10 a.m. and 4 p.m.
Wind power comes only from steady winds, and hydropower depends on either the current of the water or the pressure of the dammed-up water.
It is where a human power generator demands no such precondition.
Though limited by the amount of power that a human can produce at their maximum, this works anytime. You can produce human power every moment you need it by just pedaling or cranking.
Final Thoughts
That is our list of the best hand-crank generators. We have included all the cool models of hand crank and pedal power generators on our list. So, it might be quite useful for someone to choose the right product to make his or her life outdoors and off the grid, powered by pedaling or cranking.
There are actually not many hand-crank power generators, but we have some impressive pedal power generators and crank radios to let you produce manual power for an emergency. Of course, you can’t produce a big volume of power with these little generators, but they are good for survival life.

I purchased a version of the Tuopuke 0-28V Hand Crank Generator. The one I purchased had no bells and whistles and was rated at 15V, 0-3 Amps at 120RPM. The 120 RPM is what sold me. Quite often people pay no attention to the amount of cranking you have to do to reach the advertised Voltage and/or amperage. Mine was waterproof and had the militarry type connector and did not have the voltage regulator package either. This is a rare earth Magnet device, it’s gears inside are Metal and the crank is plated Brass. I tested it at 60 RPM and got my 15VDC @ 1.77 Amps which is not quite 3 amps, but I was not cranking it at 120 RPM either. I am sure if I cranked it at 120 RPM I would have reached the 3 amp rating. The 15 V version I purchased is perfect for charging any 12 VDC Battery Pack. It is superbly built and does what it says it will do. I only paid $38.88 for mine. WHAT A BARGAIN!!!!!!!
