No, I haven't used it. But as a graduate electronics engineer I know a thing or two about electrons and radiation. And what their website says:
Overlay Plus Power Extender is made of a newly developed speical material, PAT.P. This material generates cavity radiation energy and dissolves slougs stored in the battery. This improves the flow of ions and hence will be able to improve battery power significantly.

This is pure nonsense. The law of conservarion of energy dictates that enegry cannot be "generated". It can be transformed and stored, and that's what a a battery does. If there was something that really could generate energy, it'd be a perpetuum mobile, and whoever would have invented it would become the richest and most famous person in the universe, and certainly would not have to sell Mobile Phone Power Extenders...
Another argument, from another point of view: Mobile Phones are a competitive business. Manufacturers try almost everything to improve their phones over the ones of the competition. If that power extender really worked, don't you think some big manufacturer would have bought and used it in all their phones by now? After all, a 30% increase in battery life is a very nice selling point!
Cheers

I think it claims to make the battery more efficient, but the explanation how makes no sense to me either.
Buy a spare battery and get 100% extra battery life. Guaranteed.
I'm thinking of buying the Martin Field Overlay plus Power Extender.
I've read lots of review of it and it does make a difference, 2% ~20% depending on the product tested on.
To date, no one has tested it on the XDAII.
If someone has, I wanna know the results.

Don't any of you remember the little 'sticker' you were supposed to put on the back of your cell phone to 'enhance your coverage area'? Ever heard of 'snake oil'? This product takes advantage of people who buy into hype. It's quite impossible to put a sticker on the back of a phone and make the battery last longer. Trust me on that. But, if you're into such out of this world miracle cures, here's one for you to buy...

Maybe it'll make your XDA or XDA II get better coverage. I wonder what would happen if you used two of them?? :wink:

Well to me this product is a good reason NOT to buy ANY Martin Field products.... I am a little unforgiving in regards to things like this though
You have to be really sleazy to market crap like this. Scumbags.
BTW, the stick-on antennas often actually DECREASED signal in many tests. So I guess you can't say they "don't do anything..." :roll:
I'm offering a treasure trove of supplies to the lucky HTC Apache VX6700 owner!
If it wasn't because my work recently upgrade my phone to a VX6800 Mogul... and traded-in all of the VX6700 Apache Pocket PCs - I wouldn't be parting with these!
For the past two years - I've gifted my trusty Pocket PC phone with a wide variety of add-ons and "must haves" - from countless software programs (thank you, www.handango.com) to more than just a few spare batteries (as we often spent a week away from any power outlets). Since I not only docked my phone on my office desk, but also charged it in the car, as well as at home, I have three desk-style charges made exclusively for the VX6700. Two from Seidio, and one that is rather fancy - with a clear stylus that - when put into the hole on the stand - glows blue. Each of the drop-in desk chargers come with their own plug-in wall chargers (one simply not shown, as it's still in the original bag). We also have two additional belt holster cases, one a fancy leather side mount case with magnetic clasp. .As you can see, the Seidio chargers can accommodate many of the larger extended use batteries, as well as recharge the phone at the same time. So does the fancy model!
The batteries are each fairly new and hold a reliable charge... the most recent being a 1500mAh/3.7V Li-ion olymer battery - from Seidio only just purchased 12-29-07. The others are: another 3.7 Li-ion Battery, a UTstarcom 1350 mAh/3.7V Li-ion battery, and an extend-use 3.7V Li-ion battery (for when you need longer talk or access time). Two battery covers for use with extended batteries is included in this offer. We upgraded this past February, so the new battery hardly got two months worth of use.
I have also included three extra stylus - as I could we kept misplacing them. Two of these have a little ball in the shaft - to keep it in place when slipped into the phone.
I've also included a spare Motorola/USB cable - as you just don't know where you'll be when you need one!
Lastly, you'll find one of the best industrial-strength metal cases around! This truly is a great device to protect your phone, as it has a healthy layer of inner foam to act s not only a shock absorber from the accidental fall from the him (albeit that never happened with me) but it helps to grip and nest your pocket PC in the holder... nice and snug-like. The metal case is covered in a flat black enamel and has ports to allow not only access to the camera, but also the external battery port on the rear of the phone, as well as the speaker. Side access to all buttons is also easy. The front offers a clear window for ease of viewing - without having to open the case each time you need to see the screen! This comes with it's own belt clip, too.
All items I'm offering - I purchased either through ebay, or directly from the vendor.
Combined, these cost over $175...! I know - as we had to explain their purchases to our bookkeeper - for tax purposes.
My loss is your gain...!
Good luck... and, Thank You, for your kind consideration.
And how much are you asking for these items?
"How much" you ask...?!
You know, as soon as I posted the missive, it donned on me that I didn't say how much we were looking to get for the lot. We'd be willing to let it all go for $100, plus shipping. Surely a fair cost - considering all that is included!
If you want to break things up, pm me, I might be interested in a extra charging stand and maybe a battery or 2 (if they are fairly new).....
If you decide to split up the items, I'd like to know how much the metal case costs if it permits you to slide out the keyboard while its on...

demonstrated tech that enables devices (demonstration includes the G1) to be charged wirelessly..
It's been talked about for a while, but nothing concrete has been shown before!
Supposedly available within 12-18 months!
Topic sounds very interesting
But I couldn´t open the link
The emitter has to be very powerful for the charge current to be high enough on the device being charged. There's also a huge waste of energy that grows exponentially with the distance. This is one of the reasons this technology has been primarily used for short range applications so far. This is exactly how wireless keyfobs/smart cards work, but their useful range is limited to 1 meter or so and their consumption is minimal in comparison with mobiles.
Heck, I even have my electric toothbrush charging this way and my electric tea pot drawing power from the base wirelessly, but effective range is millimeters in these cases.
Nobody knows for sure what kind of effects strong electromagnetic fields have on humans. Knowing that electric impulses drive our brains and bodies too, I think strong electromagnetic fields are more than likely to cause major interference. IMO it'll be a while before healthcare people approve use of this kind of chargers.
This morning while searching ebay for reasonably priced solid gold toilets (or other things just as frivolous) I happened across a micro USB solar powered cell phone charger. It was priced at around $35, and while I had no real interest in buying something that probably doesn't work, it still made me wonder what if it did?
So lets assume my galaxy s3 is a 2100 MAh 3.8 volt battery, and it instantly charges to full when plugged in. This means it would consume roughly 8 watts every time you charge it from 0% to 100%. Lets not get overly technical and try to factor in the energy used by your charging cord.
Electricity in my state (New Jersey) costs roughly 21 cents per Kilo-Watt Hour (KWH). This basically means for every hour I use 1000 kilowats, I am charged another 21 cents on my electric bill.
This means if I charge my phone from empty to full exactly twice per day, I am roughly spending $1.23 per year to charge my phone. If the cost of electricity stays the same, it would take me 28 and a half years to break even on the cost of the solar charger.
how much would it cost you?
Since most of my charging is done at work.. cost me nothing.. Really though.. you are on to something... if only could mass market that and people would catch on then it would be great..
Well I think they'd have to really improve on solar energy technology before anything like this is realistic....I just saw the product as more of a novelty. Even if it does work its probably going to net you a couple percentage points an hour, nothing practical.
I just posted this on my facebook page and the response I got made me realize the smarter option would be to get solar panels for the house instead!
i think the purpose of a solar powered charger is for camping/hiking trips where electricity is not available and you can charge your ipod or phone

I'm sure it has many prudent real world applications, I was just a little bored and thought this would be something a little fun to keep the juices flowing.

i should mention that the concept is the same for hybrid cars. you pay a premium for them for gas savings that could take awhile to pay off (not including special maintainence, etc)
but maybe be part of something bigger... be green
You could use your car charger that uses your car battery/alternator to charge your phone if you are worried about using your home electricity! Just like one post said its more geared towards camping/hiking our any outdoor activity where electricity isn't present.
I gave a gift of a radio that takes alkaline batteries, but also has (replaceable) lithium batteries that can be charged via DC adaptor, built-in solar panel or hand crank. The solar panel allows for the radio to have battery power from the rechargeables without having to crank anything, especially if this radio is kept out during the day at a beach or campsite. It has a connector for charging devices such as mobile phones, which would essentially take much of the day for a low charge - but, that is most practical for when other sources of power are not going to be available for awhile.
While shopping for that radio, I came across solar chargers that are dedicated to supplying devices with power and are thin, flat products that often unfold and have greater surface area than a typical device with a (small) integrated solar panel. Some of these are expensive, but your ability to put a more substantial charge into a battery backup (for general use) or directly charging your phone without any sources of grid-based power is the primary purpose, I feel. A Brunton Explorer2 or similar is something I would go for in these cases and the issue is not comparing their economy to grid costs of the current day, but long-term ability to have off-grid or backup sources of charging power when you need it, I figure. Plus, incrementally going green isn't ever a bad idea: if I owned a solar charger, I'd keep my phone off the USB or wall charger most of the time.

I did some looking into this. It would take about 19 years for a Honda civic hybrid to pay for itself. Accounting for average miles driven across the US, maintenance of the car, and gas milage. I was bored

Don't think they're meant to pay for themselves, as they aren't alternative power sources - they are parallel hybrids meant to stretch the use of their gasoline engine.
Something like the Volt is a more serious version of that concept, being a serial hybrid whose wheels run almost exclusively off the electric motor.
Being "green" isn't always immediately the most economical choice in these relatively early days of people realizing it's beyond time to try and minimize the speed of global warming, etc. But, it's meant to be an incremental choice towards more responsible use of the dirty resources we know and love. IMHO.

You have to believe global warming exists in the first place. Just keep in mind there is as much evidence against it as there is for it.

No.
There is no scientific balance of evidence on global warming for/against its reality, and peer-reviewed studies have overwhelmingly shown its existence in a rather cold and analytical manner since at least the 70s.
Sure, businesses that seek to run away from taking responsibilities of their own pollution creation - from manufacturing or as outputs of the products they offer - do fund a number of pseudo-scientific PR studies to attempt offering the appearance of a scientific debate to purposefully keep the public wondering and debating, but no counter-evidence exists on the existence of global warming as a general phenomena in the scientific community. None.
Science is all about testing and retesting, then testing assumptions again - global warming is an easy reality to measure. Causes are still being studies, but the big ones are generally well known, and ways to mitigate are still being researched and even tried.
The business PR effort to offer an appearance of global warming debate in the scientific community utilizes easily debunked, pseudo-science at every turn - usually from privately funded studies, but sometimes they gain like-minded adherents who simply run with the misleading interpretations of highly particular data sets as part of gaining a subculture of defiance against . . . something. The man, government, smart science, whatever your cultural bugaboo might be. This is trap that people such as Michael Crichton have fallen into.
The anti-climate science PR push is equivalent to those many years of tobacco product manufacturing and distribution companies funding misinformation about the effects of cigarette smoke on human health, influencing USA lawmakers and a portion of the public to take sides against rather simple scientific facts . . . until that dangerous farce finally ran its course.
There is no scientific "debate" against the reality of global warming, and your preference for V8s (which I grew out of decades ago) has no impact on climate science - only your perception of such, perhaps.

I spent a couple minutes, because this is easy - mostly time looking up a bookmark.
Wasn't a specific point - it's the whole point about global warming. Which relates to one use of solar chargers that the OP offered, btw. That, and I have a tendency to not let nonsense get a free pass.
Your point?

Right, I'm calling out your anti-science view on a technology forum in a minor manner, which in a grass-is-blue and sky-is-green world makes me insecure, Mr. *hrr-hrr-hrr-I'm-hiding-behind-my-V8-vehicle-engine-purchases*. Lovely projection there, nosympathy - please try again, I'm all for private messages.
I'm not trying to convert you: you're simply wrong, dangerously so. I'd like others to see that your unsupported "opinion" (which is actually willful ignorance - for which you haven't offered a shred of evidence) - seems entirely counter to talking about actual science that can power or be otherwise useful in using our favorite pieces of techology . . . which were created, in essence, by people who studied one or more disciplines of science. Actual science, that is.

Interesting discussion. We can try to be civil to one another though...
That said, my 2 cents:
Recent data does support that global temperature is rising. The question that's hard to answer (and has been unproven to date) is whether this warming is man-made. Could man-made pollution be a factor? I think so. Is it THE factor? That's open for debate.
Hybrid cars: just food for thought - how are we getting rid of all those batteries?? I can't imagine those battery-acids are earth friendly.
....and no one is even discussing about the EMF generated by hybrid cars. EMF is ionizing radiation - ie. it has enough energy to break DNA (cancer risk, people!!). So if you driving a hydrid or a Volt/Leaf, you're sitting inside a pretty high EMF field. Personally, I can't take that chance with my little kids.
Solar panels. I think they're promising. Would love to get solar panels for my house. (1) too expensive. (2) efficiency sucks. Best panel is only about 20% efficient. Hopefully this will get better soon. Sunlight is free. Might as well figure out a way to use it!

Smartphones (and to some extent laptops too) have evolved to be an end product in themselves, instead of being tools to communicate and get work done.
Until this (unfortunate) nature of smartphone changes, it is unlikely that the product transforms into the category of 'consumer durables' where people would simply buy it and then forget about buying a new one for years, until the existing one starts giving problems, even if that means more than 10 years of usage.
Hardware used on smartphones are maturing in terms of the experience they provide. Every year the newer iteration is marketed to be x% more efficient, y% more powerful, etc. All those improvements are seen only on paper.
My Samsung Galaxy Note 2 that I purchased in 2012 was giving me 4 to 5 hours of SOT (initially). My Samsung Galaxy S22 Ultra that I purchased almost 10 years later in 2022 is also giving me just about 4 to 5 hours of SOT. This despite the CPU, GPU and other components becoming more powerful, more power efficient with each passing year. Also, the new phones have significantly bigger batteries than before. One can argue that the quality of apps, games, display, etc. are significantly better than what they used to be 10 years back, and they come at the cost of drawing more power. Still, these do not even remotely explain the numeric gains reported by tech companies. Or in other words, the numbers reported are manipulated and would be true only in very specific conditions, which are far from real life usage.
While many users complained about batteries being non-removable, RAM and other components being non-replaceable/ repairable/ upgradeable, etc., the direction taken by manufacturers seem to suggest that the market doesn't care as much about these factors.
Miniaturization and sealing components to the motherboard that result in slightly smaller form factor are not only profitable for the OEMs, but also seem to be acceptable to the market. This actually comes at the cost of damaging the environment, a complete opposite of what OEMs claim.
Just as Type-C has become mandatory, should there be laws that make modularity/ repairability/ component replaceability a must for products? This will eventually transform this product into the 'consumer durables' category, which will not only save the environment, but also make lives much better and healthier.
I think this is unlikely to happen unless a new (life changing) product category is developed and people start perceiving smartphones (and laptops) as mere tools to communicate and get work done. Currently, the amount of time people spend on smartphones doing useless stuff is a criminal waste of time that can otherwise be spent in doing productive things, that will not only make their own lives better, but also contribute to improving the environment and the economy that would improve everyone's lives.
