This is a medium-sized LED flashlight that you never have to buy batteries for or find an outlet to plug a charger into. You just flip out the handy dandy handle and wind it for about one minute; this is said to provide you with 20 minutes of light.

The instructions warn against disassembly, but I need to do it to find out what kind of battery is inside...BBS...there, done!!! A built-in LIR2032 cell (3.6 volts - is similar in size and shape to a standard CR2032 lithium coin cell) provides power to the LEDs.

The wind-up rechargeable flashlight comes in an attractive plastic body, with black plastic grips on the sides to help aid in retention when you're using or recharging the flashlight.

Above, the top photograph shows the product as it would normally appear during use or storage; the bottom photograph shows it with the charging handle folded out.


SIZE



This flashlight came to me ready to use. When you receive yours, remove it from the package the best way you see fit, unfold the crank, and wind it at two revolutions per second (120RPM) for ten minutes. This is to ensure the internal battery is fully charged and ready to go.

Once this is done, you only need to crank it for one minute to obtain 20 minutes of light.

Press the button on the top of the flashlight until it clicks and then release it to turn it on. Press & release the button again to turn the flashlight off.



This product does not use disposable batteries, so this section really isn't needed.

To charge the built-in rechargeable cell when necessary, unfold the crank and wind it (in either direction) at 120RPM (two revolutions per second) for one minute, then fold the crank back onto the bottom of the flashlight body; this should provide you with 20 minutes of light.

According to the package, it should be charged every three months (by winding it for one minute), whether you use the flashlight or not.



Because there are a number of moving mechanical parts inside this flashlight, the "smack test" really isn't that appropriate here.

Same with The Toliet Test. The packaging does state the product is water-resistant, but not to drop it in water. So I would not have performed The Toliet Test anyway.

So this section of the page will seem more bare than this section of the page on a page about a battery-operated (using disposable batteries or batteries that are externally recharged) flashlight.

The handle on the end of the charging crank is on a swivel, so it is easy to hang onto while charging the flashlight.

The flashlight is in a very attractive body; it comes in a black and brushed chrome finish. As a whole, it looks a lot like a small starship. Well, a very, very, very, VERY tiny starship.

UPDATE: 00-00-00



PROS:
Never have to buy disposable batteries for it
Never have to change the bulbs
Futuristic, ultra-modern design
Charging does *NOT* resemble a "spanking the monkey" motion


CONS:
Not waterproof or submersible
Potential fragile construction - but all dynamo lights are. Will not figure too much into rating
