Charging Razr from my car USB port

Greetings,

Since my car has a built in USB port, I was wondering if it would be sufficient to charge the battery in my Razr?  Given that I can charge it via a USB port from my PC or laptop, would there be any reason as to why it wouldn't work in my car?  I have the Verizon car charger but was thinking this might be a backup.

Thanks in advance,

John

I was told VZ sales that USB charging takes > 2x the time to charge the Razr vs the cigarette lighter --- fastest charge is obviously AC

I haven't heard many successful reports about USB charging, which might just mean they don't post.  But it does seem that there's a tendency for USB charging to not work well, or take a long time.  But you can try it - it won't hurt.  If it doesn't do the job well enough, at least you know you're not alone.

Exactly what is that port used for? I can give you a better answer based on what it is used for and what it is coming out of.

It is tied in with my audio system.  I typically use it to plug in a flash drive to listen to pod casts and music.

It should charge, but probably not enough to cover the drain.

Correct because most ports only push out .5 vs. Ac/adaptor which is 1.5-2.5 iirc.

If you have a iDevice charge port, I recommend this cable which will convert it to a microUSB charge adapter and headphone audio output. Very nice. http://www.cablejive.com/products/dockBossplus.html.
