NightStar Shake Flashlight Capacitor Energy Storage. Years of Worry Free Operation with Zero Maintenance. The Ultimate Survival Flashlight

I used this light in a backpacking outing in sub-freezing temperatures. It requires a "priming charge" according to the instructions that came with it. Although the initial charge took several minutes, this held its charge very well. Not as bright as my LED headlamp, but was sufficiently bright. The glow in the dark switch is a nice touch too. A bit expensive, but the build quality and never needing battery replacements is quite nice.

made in USA, this my second one (one for basement/attic another for the car/camping) durable (casing is plastic) not fake imitation with a battery hidden in the head no leaky NiMetalhydride, Alkaline, etc no Li-ion that losses overall capacity over the years no manual squeezing that tires you out for a very weak light and breaks after a few uses last for a few minuets (I usually only need it for a few minuets) shake a few times for normal light, shake for one min to a minuet and a half for bright light(full charge) holds charge for a long time (if you have not used it in years, will need a few shakes) (don't be violent with it, shaking it so that the magnet slides from end to end, it is about repetition not force) (a child can use it, some elderly can use it, it doesn't need the full force of an adult male)

A $70 price for this plastic flashlight is a joke!!! Keep in mind that a 25 watt LED bulb puts out 2000 to 2500 lumens - this crap is only 150 lumens, it barely reaches across the living room, You can get an Everlast shake flashlight with 1500 to 2000 lumens for only $12 - $25 on eBay. I would go there this is not worth it.

The NiteStar JP flashlight is certainly unique. The tough polycarbonate body will handle just about anything that comes along. And you will never be fussing around with missing or dead batteries. The capacitor that this flashlight uses has the ability to last for decades.

It's fun to behold at and to own one of these things. ALL the science put into it. The only thing I did not like about this flashlight was, it's not bright at all. I followed all the instructions to my knowledge; and it's just not that bright. Maybe I'm doing something wrong or I'm just not shaking it wright. But I just perched this to have it an case of an emergency or if my home is out of current/electricity.

It is really cool and really sturdy but something that bugs me is that the on/off switch keeps popping off. Overall great product but continuously lies in their photos it did not come with a strap, and why did it have a black version. It isn’t very bright but I would recommend gluing the button on.

The Nightstar JP shake flashlight is a superbly engineered survival flashlight with excellent product support. The brightness level and light duration are impressive. I would buy another.

Fun and perfect
