Question: Will it charge a laptop?
Document: I was hoping to use it on my laptop but the connector does not have a center ground. It's fine for my Microsoft Surface, iPad, and phone.
I thought if you cranked it it would hold a charge for a time. But it is what it is.
This is meant for emergencies really. If you want to fully charge something expect to be cranking for a couple hours straight.
Very good buy, but you really need to give a lot of thought to conseguri some charge the cell to sites where civilization has not reached, it is a good article.
These batteries don't require any man-power, and hold a lot of charge. I would highly recommend this device to outdoor enthusiasts, or people that would simply like to have a more entertaining way of charging their phones.
))Overall, it is a great product and I highly recommend it to anyone who lives in an area of the world that experiences power outages, or just anybody who needs to be able to charge their cell phone wherever they are at, no matter where that's at.
The K-Tor is very keen on doing what it says it's going to do. You'll be able to charge or power up just about anything that runs off of a standard 120 volt socket with one of these.Pros:-Durable (Probably can be dropped a few times without having to worry about it breaking.
Two, it is a manual generator with no battery and no residual or held power. So if you're not spinning the crank (which can become tiring in and of itself if you're not use to it like me) then it won't charge anything. I don't consider these to be enough of a negative to fault the device or manufacturer however, like I said I really like this little generator.
I remember after Hurricane Katrina people were frantic to contact people with their cell phones only to have the battery die without a way to charge them. This handy little device can be a life saver in those kinds of situations. You simply plug in your phone the way you would in any electrical outlet in your house and after a little cranking, your battery is charged and you have a means of communication again.
Very nice small hand crank generator. I've been able to charge my phone easily with it. It also folds together nicely to just larger than a 16oz energy drink can (the only thing near by that is of equivalent shape). It has a thick rubber band/strap to hold it while folded and to hold your plug in place while cranking.Things I've noted. One, it is a little awkward to hold.
Answer: I suppose it could, however it would take a lot of cranking the handle.  Cranking the charger is not easy and providing a constant cranking motion would be a big challenge.  I have 'practiced' supplying energy to a lamp with this (as it is suggested) and I got tired doing so.  Remember, this unit doesn't store a charge, its not a battery.
