What are Hand Crank Generators?
A crank generator is a device that is used to generate power by cracking a lever or a pedal attached to the device. The generators are portable and can be used to power multiple travel devices which ‘don’t require much electricity such as phones.
Hand crank generators are lovely devices for vacations, and which you can rely on for powering your small electronics.
The best thing about hand crank generators is that they only require your strength to generate power. These generators do not rely on gas, stored energy, or various weather aspects such as wind or sunlight.
All you need is your muscle, and you are good to start charging your devices.
Most people may view them as an outdated source of power, but wait until all your devices, including your power bank, runs dry.
How a Hand Crank Generator Works
With hand crank generators, you are practically the source of power. These devices will use your power when you are turning the crank, to generate electrical energy. When you turn the crank, the generator converts your muscle energy into electrical energy.
These devices can generate energy using an inbuilt dynamo. The cracking process alternates the dynamo, making it generate power in turn. When the dynamo generates the power, the power is then stored in an integrated battery from where you can use it later.
Most of the generators contain an output port to allow you to connect and charge your devices. They provide you a simple way to produce off-grid power, no matter where you are in the globe.
With these hand crank generators, the amount of voltage they generate is directly dependent on your effort. The longer and faster you turn that crank, the more the resulting power you will get.
Since the generators have an in-built voltage regulator, you need not worry as it will maintain a steady flow of current to avoid problems when charging.
Also, although some hand crank generators are built for specific devices, most of them are versatile and can charge multiple devices. Most of them contain a cigarette lighter socket, a typical electrical socket or electrical lead which enable you to plug in various devices.
With just 1.5rpm, most modern hand generators will give you around 5 volts. For 2rpm, you can get about 6.2 volts. In most cases, the generators can generate up to 6V although, some come with gearings, which enhances the cranking and therefore can create higher voltages.
Things to Consider Before Making a Purchase
Knowing what exactly you are looking for can make things a lot easy for you. Based on your needs and preferences, it’s good to consider the following aspects of the hand crank generators before you buy one.
You ‘don’t want to buy a generator that will not give you enough energy to charge your gadgets. That would be a waste of time and money, and it might frustrate you in the end. You should be sure of at least how much power you require to make it easy for you to search for a device that suits you.
Various uses for your hand crank generator will determine how much energy output you need.
If you are going for an outdoor adventure or backpacking, carrying a massive or heavy hand crank generator may cause a lot of unnecessary inconveniences.
It will be bulky to move with it around, and you will not be able to carry it for long. Therefore, you should look for a lightweight device that ‘won’t be cumbersome for you to take around.
Another important thing you should consider is your budget and the price of the generator. You ‘can’t afford to throw too much money that may affect your whole budget. Buying a gadget that is within your budget will help not to strain your finances.
Also, you should avoid buying the cheapest generators as the low price may also translate to fewer and unreliable feature.
Durability and efficiency
You must find a hand crank generator that will not break with the first exposure to harsh conditions. Especially if you are going to a place where weather conditions are not very conducive, a hardy device would be necessary. Also, the efficiency of the generator to produce electrical energy is of immense importance.
The main intention of getting the device is to ensure you can get that energy when you most need it. A generator that is not efficient in that will spoil your travel.
