It is different technology - both happen to utilize "induction" within their implementations, but they are totally different and incompatible.

Just like a Diesel and Gasoline engine are totally different technology, that happen to both be "internal combustion" based.

"Inductance" isn't a 'technology' any more than "capacitance" and "resistance" are. Those aren't technologies, those are the fundamental building blocks of electrical engineering - the primordial ooze of fundamentals from which every technology utilizing electronics is born from.

This is full of misinformation.

A touchstone charger uses induction (as you stated above - I believe you may not understand induction?) to transfer a magnetic field between devices, causing a current to flow in a coil placed in it's magnetic field - in this case, the Palm battery door parts.

Yes, a touchstone will be less efficient than plugging in a USB cable directly. And a 1A capable charger plugged into a touchstone base may only charge at a rate somewhere equivalent to a 500ma or 600ma charger... that's tied to the efficiency of the transfer of current via magnetic fields vs. a nearly lossless method like plugging in a cable directly. It's not a reflection of how much "power" you supply to the touchstone.

A wall charger and a car charger both supply 5v DC to your device (or touchstone). Here's an area where the car charger actually is better than the wall, because there's no conversion via inversion from AC to DC. The signal is straight, pure, actual DC. If you were to look at the waveforms on a scope, you'd see that rectified AC is not perfect DC - but it's "good enough" for our charger.

My point is - the wall doesn't give it any more "power" than the car - in fact, in both cases, you are limited by the charger you are using, and ultimately the draw from the device itself. Ohms law applies.

Many home and car chargers only supply 600ma, 750ma, some are 1A, a few are higher. A 1A home charger will supply the same power (at 5v output) as a 1A car charger, and vice versa. The power you get from a 1A car charger is the same as a 1A home charger - possibly cleaner, if anything.

An inverter in a car would make no sense, because you don't have AC in a car.

It has nothing to do with how much power a charger provides.

And the real issue with the Touchstone, and why some chargers work and some don't, is that there appears to be a requirement for the data pins in the USB circuit to be shorted - which may be done in the charger, the cable, or presumably the Touchstone if you felt like modifying it. The supplied wall charger has those pins joined - and some car chargers do as well. Some apparently don't.

It has nothing to do with the power the car charger provides.

Exactly why I stated I was curious what the results were - if this is a device that's actually been designed (or at least tested) to work with a Touchstone, or whether this is an Amazon seller who just slapped common search-for terms to his product listing.

We don't know until someone tries it and reports their result.

What this listing is, is a more promising starting point than just blindly throwing a dart at "all car chargers" to find one that works.
