Tools and Hardware Reviews of Shake Flashlight- No Batteries- Simply Shake to Recharge
Customer Review: How does this thing worth
Summary: 2 Stars
While our flashlight seems to work, I can't help but notice that it has a lithium button battery, which might explain its function. The "Magnet" is actually a piece of lead. So how does it really work? Shaking it definatly increases the brightness, but it seems it is assisting the magnet.Customer Review: Just doesn't work
Summary: 1 Stars
The shake flashlight just doesn't work. Holds a charge for about thirty seconds and is not bright enough to actually use. This is my second one and both had the same problems.Customer Review: LED Shake Light
Summary: 3 Stars
OPERATING: Just like the larger shake lights, you have to shake them back and fourth to charge the capacitor. You can visit their website for the detailed expert instruction on how these lights work. Basically what happens is, as the magnet moves back and fourth inside the coil, the magnetic field produced by the magnet, creates a electric charge through the coil. This electric charge is then past on to the capacitor. Then the power stored in the capacitor is then discharged into the LED inside the lens.
MINI LIGHT: The mini lights are, well, mini, small enough to fit in your pocket, yet still contain the regenerative ability to recharge. Its just all the parts are made smaller, smaller coil, smaller magnet, smaller capacitor. And that becomes the downfall over the mini lights is the smaller capacitor. It does not hold nearly enough power to power this light for an extended period, and nor will it continue to store power after 24-hours have gone by while not in use. I just don't like them because they don't put out nearly enough light for me. Good stocking stuffer though! lol You have to keep holding the button down for it to light up.
STANDARD LIGHT: The standard lights are bigger, I like this because I can hold them in my whole hand, gives me a better grip that way. The parts inside are bigger, including the capacitor. I like these lights much better because the capacitor is actually large enough to hold a charge to make these lights useful! And if I choose not to use the light for a week, or a month, the capacitor is still holding the charge! This makes them much more useful in my opinion. And on top of that, they are bright too, still use a single LED, but actually illuminate enough to be worth something. You still have to continue to hold the button down to light up.
LARGE LIGHT: The large lights are by far the best of the breed of shake lights. The parts are slightly bigger then in the standard lights, but the light itself is much longer in length. These ones are my favorite, because not only are they the brightest of the bunch, still using a single LED, but they last the longest on a charge as well. I like these ones better also because of the slide switch instead of the button. I can flip the switch on, the light will come on, and I don't have to continue to hold the button down. This way I can use it while working, such as, adjustable temperature settings on my hot water tank.
POWER TO SHAKE RATIO: OK, here is the only down fall with these lights. If you want 2-minutes of light power, you must shake the light vigorously for 30-seconds, not too bad right? But if you want 8 to 10 minutes of power, you have to shake for at least 2-minutes. With the mini lights, because they can't hold a charge worth crap, you have to shake them for 2-minutes just to get a minute of power out of them.
DURABILITY: These flashlights are all made out of plastic, and they are made to be very durable. So durable infact, they have been rated to be run over by a car, and still survive! I totally feel they are durable, the plastic is very tough, I have not broken one yet, and nor does any of them have cosmetic damage. I love the transparent look, being able to see the insides is cool.
CONCLUSION: There are crank lights and shake lights for regenerative power. Our first ones were the shake lights. When comparing the shake lights to the crank lights, I am sorry to say, I rather have the crank lights. Because for one, an elderly person with arthritis will be able to crank charge a light a lot easier then shaking one. And a crank light takes less cranking to charge a light vs the shake lights. All in all, I do like the shake lights, but they surely are not the best for regenerative power. I give them all a 3 out of 5.
Customer Review: Not good!!!!!!!
Summary: 2 Stars
This item was purchased as a gift and I was very unhappy when I received the item. The box it came in was very bent up and the top of the box would not even close properly. The flashlight was missing the cord to hang it from and it was hard to get to work after following the directions. I would not buy this product again.Customer Review: Poor light - Looses charge fast
Summary: 1 Stars
I have been purchasing a few of these self charging flashlights lately to find the best one.
This one puts out a a poor amount of light. It also does not retain its charge well. You will have to shake it frequently to keep it charged.
I would say it is one of the worst ones I purchased.
