Hi all.
I was using generic docks/cradles for my Rezound and was starting to get concerned that, since the power port is on the bottom, I'd be putting too much pressure on that jack and I'd screw it up eventually.
So I sprung for both the Verizon Desk dock and the Verizon Car dock; both purchased at a local Denver verizon store.
The Desk dock works flawlessly WITH the installed extended battery and back and comes with power supply and cable.
It will NOT work with the extended battery AND any case that covers it to use with a belt clip.
Yay for the Desk dock/cradle.
The Car Dock is another story.
It mounts to the window perfectly. Plugging the power cord (not included) into the dock is a major pain and I could only do it with the dock in my hand. One big drag is that the OEM A/C power cord that comes with the Rezound and the dock will NOT plug into the Car Dock. It MUST be a standard micro usb end. Ooops Verizon.
Granted, one could only use that cable plugged into a power invertor but it's not like those are so uncommon.
Now the worse part.
I put the phone in the dock and fired up the navigation. The battery level was at 65%. I drove across town probably 30-45 minutes. The battery level stayed exactly the same the entire time. I've heard of people complaining about this so I did some experimenting.
Using a very cool free battery app called Battery Monitor Widget, of which I will be purchasing since the Dev has done SUCH a good job, I plugged the aftermarket DC power adapter directly into the phone. I've used this adapter with my D1 and with the Rezound and it worked. It charged the phone WITH navigation on.
On the main screen of the BMW (Bat Mon Widget) it shows if the phone is charging or discharging, if it's plugged into AC or DC power and the level, in mA, of charge or discharge.
When the DC charger was plugged directly into the phone I was getting +357 mA.
Plug it into the dock and mount the phone and it only gets +25mA!!!!
AND it fluctuates. I got as little as +7mA!!!
That means that either the LED in the dock is eating up 350 odd mA, or the dock has that much resistance.
FWIW the rating on that charger is DC 4.75-5.25v and 0-950mA.
Further testing ensued.
I plugged a stock OTA AC charging cable from my D1 into the power invertor. That charger is rated at 5.1v and 850mA.
Plugged straight into the phone I got 674mA. Plugged into the dock then the phone I got 485.
Again, a substantial drop in amperage, though it was only 200mA this time.
So, considering that I like the dock, I began looking for a DC charger that had more juice.
Walmart had one that they rated at 5v and 2000mA and is made to charge two phones simultaneously.
Ugh.
It's junk. I don't know how they can claim it puts out 2amps because plugged directly into the phone I only got 125mA, or something like that.
Ridiculous!!
So, finally, my questions.
Anybody know of a DC charger that will put out upwards of 1000mA at 5 volts?
Thanks.
