I am using a generic two-port USB car charger bought from Amazon since Feb, have had no problem charging both my Droid and TomTom at once. I'll give you the link to that one which I bought. You need to be sure the charger you get will output at least 500 milliamp or more, this one does it like a champ.

I'm have a Motorola charger (P513) and it works. You just have to make sure the charger has a high enough output.

I should mention that I actually use the USB cable that came with my phone, along with a belkin car adapter USB charger port, it fits much more snug than the motorola charger.

 

I use the motorola car charger, and it works great.

 

Ditto, I use the one that came with my wife's EnV3, it works perfectly.

 

Using the OEM charger since February. Perfect for Nav and charging, in fact it charges very quickly in the car.

 

I am using a motorola charger, I'll have to look at the power it puts out when I get in my car, later... I thought I noticed that after a drive where I had the GPS on the whole time that the phone had not charged at all, so perhaps mine is no better than the one Verizon tried to sell me.

 

Is it the OEM charger for the Droid? That is what I have as there are many different Motorola chargers.

 

Which one? They make many. My SPN5400A/P513 outputs 950mA which is plenty to charge while using GPS.

500mA is USB spec which trickle charges. I suggest getting as close to 1000mA as possible.

 

i have the VZW charger for my droid and haveent had an issue with it not charging the droid.

 

Mine says SPN5400A on it. And, as I said, I think it did not charge while I was navigating, once... but I've only noticed it that one time.

 

I have the Motorola car charger and have noticed that it doens't seem to charge as fast as it used to. When I would drive home each day my phone would be @70% and would be fully charged by the time I got home (30 minutes) Now, it may only go to 80%.

Mine also drains while using Navigation. I was driving for 2.5 hours last week with the Navigation on and plugged in. Went from fully charged to 60%. I also had Bluetooth on.

 

I bought a charger at wal mart and it works fine. =)

 

i got this combo pack and the car charger is quite fast and also works with my wife's bb.

Go to wirelessground.com/motoccspn5400.html. That is the charger I'm using. No issues and look at all the phones it list that it is compatible with.
