[Q] Real 2A car charger. Which one??

---

Yesterday I've been navigating again with Navigon on my SGS2, but unfortunately it slowly drains my battery. When using google maps it dous charge the phone. So apperently Navigon is using a lot more 'juice' compared to Google map navigation.

Do you people know a charger (I assume one of 2A, while my own charger is an 1A charger) which does charge the phone with bluetooth, gps and Navigon running?

I bough a 2.1A car charger from belkin and I still have battery drain.

Even with the phone detecting it correctly as AC CHARGEr.

Hmmm that's to bad
Ordered a 2A charger from ebay myself.... But I doubt it will work, especially after reading your message.
I think the phone only takes a maximum of Amps for charging, even though it uses more. Resulting in a slow battery drain.

Note that it will stopped charging if the battery gets too hot to avoid damage or possibly exploding the battery.

Obviously having a higher rated charger will heat the battery more, so make sure the phone has its back ventilated, and try avoiding direct sunlight.

Read of several people that had this issue, but got their phones charging when avoiding overheating it.

Try the Rockfish premium charger. It's 2A and looks nice.

has anyone had any luck with the motorola charger? I bought one for my nexus one + car dock and it always worked fine... have yet to have a chance to use it for my SGS2 though..

But that's a bit strange, because a charger should deliver what a phone is asking for. As far as I know, a charger doesn't push the charge to the phone. But we will see, if the phone does get overheated, then that will be the end of the charger.

You're mistaken.

The thing that you plug into your car, that's called a power supply.

The real charger is built into the phone. That's the charging circuit that will shut down the charger, stop drawing power from the power supply when the phone gets too hot.

I doubt the phone will be able to take 2A, and the circuits will prevent the phone from drawing 2A of current.

#1. So, what you're looking for is actually a power supply that provides suficient current. Most car chargers will be about the same.
The power supply is connected to your phone via cables. Badly made cables will not be able to supply more than 200mah, and as a result you're going to take a really long time to charge your phone, and with a high drain application going on, you're not going to be able to charge your phone.

I had that exact same problem previously, and it was because of a lousy batch of oem cable I bought from ebay. Original, and other brands of oem cables worked fine.

#2. You need to buy some proper cables. I buy from www.monoprice.com, because I like my cables to be gold plated.
Edit: No, I'm not related to monoprice. I just love my gold cables plated heads. Can't find them cheaper anywhere else.

But the quality of the cable is not the only thing. The phone should also see the charger as an AC charger instead of an usb charger. This can be done by connecting the middle pins in the usb cable. Otherwise it will only charge with 500mA.
