I found the idea very interesting , what do you think about it please ?
By the way some ones on the net said this is a fake seller, any idéal?
Thanks

Well, the cable could very well exist, but it will not work.

As they write

We only guarantee this USB charger cable works when you connect with a 12V output USB port

and USB is by the standard providing 5V...

Considering their claims, I'd hardly call them legit... Seriously.. "Requires a 12v USB port?" There's no such animal...

Besides which, even if you COULD pump 12v down the USB cable to the A500, all you'll manage to do is either a) nothing at all, or b) fry your A500.

Floating correct me if I'm wrong but i don't understand how you can just say it wont work or fry your a500 if there's 12v and 1.5A then how would it not work???

once again correct me if im wrong

Because the USB port on the A500 is NOT designed to take a 12v input. It's only way of charging is through the dedicated 12v power connector. What do you think happens when you push voltage down something not designed for it?

You can't connect it that way.

And my previous answer still stands.

Ah, I didn't spot one end was a regular power connector. Still, it's not gonna work anyway. Even car USB adapters step the voltage down to 5v.
