Car charger question

---

I have a USB car charger that doesn't seem to charge as quickly as I would like it to. I say that by comparing it to previous phones and the rate at which they charged when plugged into it.

I read that you can short out the Belkin or Griffin USB charges to make it look like your phone is plugged into the wall. I'm not agains doing this because i like to tweak.

The question really is, I see that Proporta has a 4000mA (2000mA per port) dual port USB charger available. Will this allow my phone to charge like it's plugged into the wall or will it still "look like" I'm plugged into a USB prot charging?

Not exactly sure what you're asking, but I assume that you mean that a wall charger charges the phone faster than a car charger.

Unfortunately, I don't know if this is the case. USB is a universal standard with specific power requirements. Although there are medium and high power chargers out there, I would be reluctant to get something so extreme. I think USB calls for 500 mA standard, so I'd be careful using the charger you mention. You might want to do some more research on it, or contact the company about it.

I'm not an expert but my opinion is that usually USB-Wall charger supplies up to 1000 mAh (written on power supply transformer) while the USB-OutPC is only 500 mAh, in fact, I've noticed that the full charge of my Titan takes double the time if charged via PC.
Not sure about the amount supplied by cars USB adapter.

...my two amperes...

Some of the chargers accomplish support for things like the iPad 2 by shorting the two USB connectors. Some advertise things like 2000ma, but fail to deliver much more than 500ma. I am not sure if this is due to the choice of shorting out the data connectors to trick your phone in to thinking it is plugged in to the wall.

Back in the WM 6.5 days, you could accomplish this at the phone driver level and did not need to modify your chargers.

I would not worry about trying something rated higher as your phone would regulate the current. I personally intend to do my experimentation by shorting out the cable rather than the charger (cables are more easily replaced). Unfortunately, there is no app for WP7 that can measure the charging current, so the only way to do this scientifically is to use the battery status app and measuring the charge rate over time.

If you do the mod, post back and let us know. When I get around to the USB cable experiment, I will post back as well.
