Question [Q] Where can I get a 1A car charger in Canada?

I bought this kit from e-bay and just got it in today, so have been trying it out on my drive from home <-> work.

The problem is, the car charger they supplied doesn't seem to be sufficient to charge the phone or at least keep its battery at a constant state when I'm using it as a GPS + Streaming music. On my drive home, I started at about 50% battery life. An hour or so later, I was down to about 35ish with it plugged in nearly the entire time. So clearly it's not pumping enough juice to the device

I was thinking of buying one of these from monoprice but I wanted to make sure it really would give me enough power. Obviously the power isn't that big of an issue, but I don't want to wait for it to ship only to find out that it doesn't help anyways.

Anyone tried the monoprice one I linked to, or one of the other ones from there? Or can suggest one to buy from elsewhere? Would greatly appreciate it, thank you!

*edit*
I should mention, I have a car charger uhh splitter thing...to split the one socket into two (one for an FM transmitter, and one for the phone). Could this be a limiting factor in how much power I'm getting to the phone as well? Or should the single socket have enough power for both devices?

I got a Kensington PowerBolt from Future Shop which claims to be 2.1 amps and I still drained the battery a bit when testing the nav. Possibly not as much as you but there is still a net loss. If the charger is accurate in its power then I presume my car isn't delivering enough power.

Any car charger that supports the ipad should be well above 1.0a. Whether it delivers that is a question I cannot answer.

Im going to test direct power charging while having the nav on to see if this thing can ever charge positive while in nav mode. I wonder if that has ever been done.

I am not aware of any car charger that is 1amp. What you are looking for is pretty rare

They are a little more prevalent thanks to the ipads higher power requirements for charging.

Future Shop has a few of them available now if you want. A little expensive though at $30+. I don't see the PowerBolt anymore which is too bad since that was a slim model that barely poked out of the socket.

This is completely untrue... did you make this up?

Griffin makes many:

http://reviews.bestbuy.com/3545/1207...ws/reviews.htm

Belkin and Kensington make them as well. Many are now 2.1A for the iPad.

But to the OP - a 1amp charger is not going to fix your problem in most cases. You need a cable with the data pins shorted so that the phone thinks it is pulling power from something other then a USB port.

A USB port only supplies 500mA - the phone will draw a max of about 750mA; but only if it thinks it is not attached to a PC. The wall charger shorts the data connection so the phone knows to pull more current.

I purchased a dual port (1A per port) charger at target or walmart, and then a took a USB cable and cut open the cable and shorted the data wires (not red or white - but the other 2). My phone says it is charging on AC power and charging keeps up with GPS.

It is possible that you could buy a car charger with the cable built in and the circuitry set to tell the phone to draw more then the USB 500mA, but I am not sure.

But know this; if the phone does not say "AC Charging" under settings->phone-> about - like it does when the wall charger is in use; then you are only getting 500mA.

I use a 2 amp 12v to usb adapter that is use for my ecig passthrough. Charges with bluetooth, streaming music, and navigation all running but charges slowly. Something like $8 on madvapes.com

Excellent. I am going to give that a try. I have one of those flat retractable cables so its going to be a pain in the ass to do but its worth it.

Oooo that's interesting, didn't know that. So perhaps the issue could be that my cable is not supplying enough power. Are there instructions somewhere detailing how to short the cable?

Do you mean this? Isn't 2 amps too much though?

You're going to need to strip a cable so so that you can get to the individual wires for each pin. You want to short pins 2 and 3 together which are Data- and Data+. Normally that is WHITE and GREEN





Once you do that, you'll have a charge only cable.




Here's the detailed directions:
