Product FAQ for Hand Crank Phone Chargers
We've narrowed the myriad choices of hand crank phone chargers down to just five specimens. We'll examine each of these choices in depth, pit them against each other and reveal our favorite. But first, it is necessary to address a few of the most frequently asked questions about hand crank phone chargers that we've received.
1. What Is a Hand Crank Phone Charger?
A hand crank phone charger is a device that can store a charge in a battery that is generated from the locomotive force of turning a crank. You can then plug your phone into the device to draw that charge from the battery and recharge your phone. The best versions of these devices offer many plug options for different types of phones.
2. How Much Power Does a Hand Crank Phone Charger Generate?
The exact ratio of effort to power isn't identical for every model. However, as a good rule of thumb, think “Two to One.” Basically, if you put in a minute of consistent effort of cranking, you will generate enough power to have a thirty second phone call. A half-minute phone call may not seem like much, but it is enough to let emergency services know where you are or get a tow truck to your location. And keep in mind that you can crank it for much longer. Many passengers on road trips find it a good pastime to idly crank the hand crank phone charger when the conversation dies down over long stretches.
Each battery has a different top capacity, but assuming your model can hold this much charge: ten minutes of idly spinning a crank will generate five minutes of phone power that will likely get you the assistance you need.
3. How Do Hand Crank Phone Chargers Work?
Generators are electronically very similar to electric motors, just in reverse. You can actually wire a drill to rechargeable batteries to get an idea of how all the parts are connected. The drill bit becomes like the crank in the hand crank phone charger. We'll tell you exactly how to put one of these together if you're interested.
4. Is It Dangerous to Use a Hand Crank Phone Charger?
Some of the simplest hand crank generators do not come equipped with voltage regulators. That means if you are connecting a low quality or exceedingly simple crank generator to sensitive equipment, you may run into problems. What sort of problems? Well, since you can potentially hand crank faster than a light bulb would use to be powered, you may be able to burn out light bulbs that were running directly off of your hand crank charger.
Fortunately, modern hand crank phone chargers have voltage regulators equipped, so that your crank speed won't blow up your phone.
5. Where Can You Buy a Hand Crank Phone Charger?
All the items on this list can be found online. Check Amazon at different times to catch different prices.
6. Can I Make a Hand Crank Phone Charger at Home?
Getting a hand crank charger to attach directly to your phone will require some advanced home engineering. However, since a crank charger is essentially just an electric motor in reverse, you can make a crank charger by reversing an electric motor like a drill. To illustrate: take an electric drill. Remove the battery. Wire the battery leads to what you want to power. (We recommend a rechargeable battery.) Then put a handle on the drill's chuck; this will be the “crank” you turn. Hold down the button to unlock the chuck, and then turn your handle. The motion should power the battery.
