I first bought this flashlight when I needed something to help me to see to the toilet block at a campsite I was staying on, where there was tents and cables all over the place, some of which seemed to stray onto the pathway to the toilet block.
My motive behind buying this specific torch was the fact that it was available from a little local shop not far from the campsite, for starters (although it was priced at £5, I thought it would at least be helping local trade) and it wouldn't need any batteries as it was powered by shaking it, which is always a bonus when you're staying somewhere without electricity to be able to use rechargeable batteries, and having to go out and buy more things for the torch (ie the batteries) seemed like a bit of a waste of money anyway, so I thought that a torch that I could power just by shaking it would have to be better than a traditional battery powered torch, really.
The design of this torch is quite a basic one. It is about 20cm long. It is mostly made of an almost see-through white plastic, although it has a black rubber bung on one end and a black rim around the completely see through plastic end where the light shines through. You can see the body of the torch through the plastic, and you can clearly see how the magnet inside charges the torch, creating an electrical current through the copper wires. It's quite interesting to watch, actually, if you have the torch turned on as you get to see it getting brighter. One thing I will point out though is that it can get quite hot where the copper wires are, so I wouldn't recommend shaking it if you take the cover off as it is hot enough to burn you within just a couple of shakes, which really surprised me considering how easy it is to get the cover off of it - a child could definitely do it, seeing as all you have to do is twist a couple of times. I would take one star off for this because obviously it's a safety risk.
When I got it out that night while it was dark, I found that it wasn't a very bright light at all to begin with, and I had to shake it for probably a good 30 seconds or so before I was able to get a good light out of it. However, I was pleasantly surprised by the fact that this light then lasted for about 20 minutes before I needed to shake it again, which made it more worthwhile to get this torch because once it was charged, it did seem to last a little longer than I expected it to.
The light that it cast was a white light rather than a yellow light like I had expected it to be. However, this was probably actually a good thing for the people still in their tents because it was a more focused light as well that really just went straight in front of me where I pointed it rather than creating a glow that brightened the entire area, which I think was a good thing for what I wanted - making sure I didn't trip on cables and such from tents.
I since found that the amount of time the light lasts for has decreased a little after 6 months or so, meaning that I now need to shake it for longer if I want the light to last for 20 minutes. However, there are 2 flat batteries in the torch which are charged by the process of shaking the torch. I tried changing these batteries, just to see if it made a difference, and I am happy to say that it took the time it stayed bright for right back up to 20 minutes, so I would imagine that every 6 months or so the batteries that are in the torch will need replacing if you use it really regularly like I tend to do, such as for walking my dogs at night. It can often get half an hour of use every night from me at times, so I would say one battery change per 6 months isn't anything worth complaining about! It's a lot more environmentally friendly than many other torches I've owned, that's for sure!
I got my flashlight from Ankaka.com. The price was way affordable - that is what attracted me to the site in the first place. Shipping was decent, not super fast but not so slow that I forgot I ordered it. The flashlight worked just as promised. So, for the low price I paid and the fact that it works, I'm pretty happy with Ankaka.
I actually bought this torch one night in a petrol station for a couple of pound. The only torch they had and in the emergency I needed it for I didn't read the instructions. I was off to rescue some kittens in the middle of nowhere in pitch black.
So when I got into my car and reading the instructions I realised it didn't need batteries and I would need to shake it to get it to work!! How this works I couldn't even begin to tell you. So shaking for a couple of minutes I decided to see how bright it was, to be honest I didn't expect anything fantastic but I was pleasantly surprised, the light is very bright and definately good enough to find little black kittens. It only took me 5 minutes to find all 5 and their mum. Very happy.
The packaging also states that you will never need to replace any part of the torch. So for this reason the torch is definately excellent value for money. It is light to carry and not too big so will fit in a jacket pocket or a handbag. Everyone should have one of these so you don't get caught out anytime even leave it in your car because if you're like me and you think you have a torch then realise the batteries have run out when you really need it like when your car breaks down.
I believe in Miracles.....and Science.
This flashlight may not be a divinely inspired miracle, but it truely is a scientific one. I might have aced my physics, chem and Bio classes in college, but even I can't tell you in coherant detail how this exactly works. Although, my father could. He's explained it too me a few times. In layman's terms, this is what I got out of it.....
You have a Generator and a Capacitor. Now for all you Electronic Nerds out there, you'll know exactly what this means. Most of us though, don't speak Electro-Language. So, simply put, a Generator in this case, is a magnet with a copper coil conductor. This magnet when it passes through the coil, creates a magnetic field that produces....small amounts of electricity!
There's a circuit system inside that takes these small bursts of electricity and turns them into current which then gets pushed into the capacator which holds a two sheets of conducting material that has a positive charge on one of them and a negative charge on the other, with an insulator inbetween. How this works, I have no idea, It's a bit like a battery only it's not....It collects this electricial charge from the magnet and whamo.....Let there be light!
*****Why this Flashlight is the Only One You'll Ever Need*****
Let's see maybe because it lasts FOREVER with NO BATTERIES? Yeah, that sounds like a good reason. =)
The only way this thing will stop working, is if you try to take it apart to figure out "how it works" or if you drop it down a cliff, or if someone accidentally sets it on fire.....otherwise, your set for life.
My dad is a gadget god. If there is an intelligent gadget out there to be had....he'll have it. When he found out these were invented, he went out and bought a few dozen. I recieved two (one as a back up in case I lost the other.....which if you knew how much I lose things, you'll know i've already lost that one).....and my sisters and brothers recieved a few and then he hoarded the rest and placed through throughout his garage, barn , and house.
Everytime I want into my parents house, I see one of these flashlights hanging around somewhere. Normally, I'd roll my eyes and say my dad is being OCD , but in this case, he's just being smart.
These flashlights come in handy at the weirdest times. Lets say you've gotten a flat tire in the middle of the country and it's dark outside with no lights around you. Well, if you keep one of these flashlights in your glove compartment, fixing your flat tire wont' be a problem. Instead what usually happens in this case? You keep a NORMAL , BATTERY powered flashlight in your glove compartment. When you take that out, it is inexpliciably ....out of power.
Or.....let's say the power went out of your house and it's nighttime.....instead of trying to find candles just keep a few of these flashlights by your door or in easy to reach places.
The times you will end up using this are too many to count. I have accumilated over 6 of these now and I still think I probably should buy a few more.
***** A MUST have for the Backpacker and Camper*****
The most obvious reason to have one of these is if your a Camper or Backpacker. They will save you from many headaches that normal flashlights give you......Do you know how many times i've dropped this flashlight in the water? At least 50......I do a lot of canoeing , kayaking and white water rafting and waterproof normal flashlights sometimes don't always work. Then you have that "battery" problem again. Even if you use lithium re-chargeable batteries, they do eventually need to be re-charged, and when your in a bind and out in the middle of the forest, you need to be SURE , a flashlight will work for you.
One time when I was exploring and backpacking with a friend in Scotland, our GPS system we had broke. Of course, it broke when we were in the middle of a climbing a very tall hill (some would call it a mountain=). It was beginning to get late and while Scotland stays light outside until the wee hours of the morning in the Spring/Summer.....it does eventually get dark.
After climbing to the top of the mountain we set up camp. We got a fire going, and cooked some dinner, then went to bed. My friend had to go to the bathroom in the middle of the night and took his "Lithium powered" flashlight with him. I was still sleeping at the time so didn't realize he had gotten up in the middle of the night. I woke up though a few hours later, still dark and, saw he was gone.
I thought he had woken up to go to the bathroom and figured i'd wait for him to come back, and then go myself. 30 minutes passed and he wasn't back. I was starting to get worried and started calling out his name. Nothing...... I got out my trusty "Forever Flashlight", shook it a few times, and started to look for him.
The mountain we were on , was a very slopeing type. At the top it leveled out, but it had a lot of gradual and sudden dips. You had to be very careful where you walked or you could slide down easily. This is exactly what had happened to my friend.....After about two hours of me frantically searching for him, I finally found him on the opposite side.
He had slipped and slide down a large portion of a slope and hit his head on a rock. It had knocked him out and he'd lost his flashlight. I was able to find him when he answered my call finally and had come too, but I couldn't have done it without my flashlight.
To have a flashlight on for two hours straight and never need to worry about it going out is very comforting when your looking for someone who is lost. My friend was ok and played the tough guy after that by refusing to let me leave him and get help to take him to a doctor. Why do men hate the doctors!??
Anyways,.....I always tell him that he was saved by a flashlight. He rolls his eys at that and says I would have found him fine in the morning, but who knows, maybe a wild animal would have gotten him or he could have rolled down the mountain further in his sleep!.....Either way, he knows now how providential this flashlight really is and has finally bought a few for himself. =)
***** Dear Forever Flashlight Inventor *****
Will you marry me?
Seriously......Your a genius. I know Edison was pretty cool in inventing the lightbulb and that Marconi was awesome for inventing the record player. You though.....your on that same level . Alright that might be a tad exaggerative. Let's just say that if those guys were alive today they would probably hang out with you.
Thank you for saving my stupid "I-hate-going-to-the-doctor-even-if-i-have-a-concusion" , friends life....and overall just being extremely useful. I think everyone should buy one of your flashlights....or two or fifteen of them.
Your biggest fan. =)
You can get these online I would imagine. I'm not sure since I bought mine in the States. They cost around $5.00 each there when bought by the Dozen and around $8.00 when purchased one by one. So they might end up being 10 pounds or so here? I'm not sure, you'll have to just type in "Forever flashlight" and see where and how much.
I got this torch as a Christmas gift off one of my aunties and when I unwrapped it I thought "wow a torch". Yeah its just what you want on Christmas day isn't it, it will provide the house with hours of entertainment and its something I've always wanted. Needless to say I thought it was a pretty crap present but practically speaking it is a fantastic product and in my opinion pure genius.
The thing that separates this torch from most other torches on the market is that is doesn't require and batteries to power it. It works through a principle known as Faraday's Law of Induction. This Law is that any change in the magnetic environment of a coil will "induce" voltage in that coil, which means electricity that can they be converted into light energy.
The torch contains a metal coil and a magnet and when the magnet is passed through the coil, by shaking the torch from side to side it charges up a battery and the electricity lights up the bulb at the end of the torch and hey presto you have a light.
The torch is about 25 cm long and is made out of translucent plastic which means that the inner working of the torch can be seen in action. The torch has an on/off switch on the top so that you the energy created by the coil and magnet can be stored and then only used when required.
The torch I must say has been very useful and my parents keep one in their caravan for when they go away and swear by it. It doesn't take long to charge it up either, 30 seconds of shaking will charge the torch for around 5 minutes and the light it emits can apparently (according to the box) be seen from a mile away.
Another little extra that I particularly like is that it's waterproof and actually floats on the water so it would be ideal for any water pursuits.
I would recommend one of these torches for anyone who is outdoorsy kind of person as its light and there is no danger of the batteries running out. I've had a scout round on the internet and found one priced £12.99 on www.internetshopuk.com.
The Forever Flashlight uses the Faraday Principle of Electromagnetic Energy that guarantees replacement parts will never be needed!
