Comments on Martin Field Overlay plus Power Extender?

[henrylim]

Hi,

Since the XDAII is such a power sucker, I am contemplating buying a Power Extender. The ad says it extends battery life by up to 30% of standard capacity.

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
Daniel

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:

HAHAHA!

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 :P

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:
