Don't know if a universal usb charger will work and if so, we still need the cable. Any thoughts?
you would have to get a USB3 Car Charger which I have no idea if it exists yet
Try a power inverter they aren't terribly expensive on amazon.

HEHEHE This just made me realize that I will get to use the plug in my rear seat for the built in inverter in my Dodge !!! The only reason I can think of wanting a USB3 charger is if I find a mounting solution for the inside of the truck...like the in dash stuff being done with the xoom and ipad.
I'm hoping to combine this:

and this:

with some soldering fun to make my own car charging cable.

Most of the 'universal' chargers out there have USB 2.0 connections.
I plugged my TF into my Nook Color charger (USB 2.0, 1.9A output), but the TF didn't react, so I'm expecting it won't charge the device. Might do it while it's powered off, but definitely not while it's on.
This leads me to the conclusion that the device will require a specific car charger. I don't know exactly how they'll get around the 15V source with a 12V car socket, tho.
While it may suck, an inverter with the regular AC charger may be the best solution. Get a QUALITY inverter, tho.
Hey all, I was looking into getting a car power adapter for hte G-Tab. I looked on Electroniccrap.com, but everything is usually "out of stock." He sells the iGo systems, which Radio Shack also sells. So, I went to my local RS to see what I could find. They didn't have the iGo stuff, but did have enercell converters/adapters, etc.
As I was browsing, I found 2 12VDC car chargers (if you were curious, the "B" plug fits in the G-Tab). But then I noticed a "150W power inverter." It's a car plug that has 3 AC outlets and 1 USB outlet on it. This is ideal for me becuase I usually charge more than one thing when on long trips, GPS, Zune, NDSi, DVD player, and now the G-Tablet. The issue I'm having is that the back of the package said that it's output was 5VDC, typical of most car adapters. I asked the girl that was working if my AC adapter for hte G-Tablet would do it's own conversion, making it's output 12VDC. She said that it would, and said that each device's AC adapter will convert as needed.
Now, my question, is this true? The charger device does have a fuse on it, and some reviews I read (after purchasing, I know) said that it's worked fine for laptops, DVD players, etc. The main complaint is the hum of the cooling fan that's built in.
I briefly tested it today, with my G-Tablet. The battery indicator said it was 100% charged (but we all know that isn't reliable) I didn't take it out of it's case ot see what color the charge light was, but the charge indicator idn't have the lightning bolt in it, indicating a charge.
Does anyone know if she was telling the truth, perhaps? It's a pretty sweet setup, being able ot use AC adapters for all of my devices in the car, if it works as advertised, anyway. I just couldn't imagine why they would create a charger that has 3 5VDC AC outlets on it...

of course not, how can someone who works in an electronics shop says so ?!
The 5VDC on the package is most probably the output of the USB port on the inverter.
The inverter should output 110 (or 220v) AC @ 50/60 hz, else you wont be able to use your wall plug adapters.
True the GTab adapter will output the proper voltage (12v DC 2A), but its input must be 110v (220v) AC.
My advice is not to use inverters for small hand helds : GTab, GPS, MP3 players .. etc.
Instead, use compatible car adapters, if you need more than one, get a splitter for your socket.
By the way, here is a compatible (and cheap) car adapter for the GTab: http://cgi.ebay.ca/Car-Charger-Koda...ccessories&hash=item51998a1f04#ht_1399wt_1341
Things may be different in Canada, but here in Pittsburgh, PA, just because somebody works at a certain store, doesn't necessarily mean that they know anything about the items they carry.
we actually have a car power splitter, it worked fine in our Honda Element (that the wife hit a deer with) but the Scion XB we have doesn't have much room between the outlet and the shifter lever, so the splitter doesn't quite fit that well. It is adjustable, but we haven't been able to find a position that works.
In fact, we have a car to double USB port adapter right now, that we are powering the GPS and Zune with, even with just the 2 USB cables plugged into it, it's tight.

Thanks for the tip - bought one!
FWIW, I'm pretty sure the 'girl in the shop' was simply saying that if you plug your 115/220VAC adapter into the inverter, the adapter will produce whatever it produces when plugged into a wall receptacle, which indeed it should so long as the inverter can produce 24W - and she was just following standard retail practice: 'sell what ya got', and the store *had* an inverter.
Seems like an overly complex way to get 12VDC out of a (nominally) 12VDC system when all you probably need is a regulator.
Another option:

Only one review, but it's a positive one.

When I had my Scion xA, there were two power ports. One as part of the dash, the other was between the two front seats... the xB doesn't have this?
5V won't work. The power management chip is designed to handle 9 to 18V, but any car charger that is 12V out and fits will be fine.
Go to Radio Shack and buy the coiled Universal Accessory Charger. Its regulated 12V dc @ 2Mah.
Mine has been working excellent for months, although i can hear a high pitched sqeel in my audio system when the charger is on with no audio playing. I attribute this to a ground issue, not the charger...

Seems the OP answered his question but I think pointing out a couple of things may be helpful to others.
Haven't met anyone working RS that I thought was stupid but almost none know anything about the electronic components I buy. To think they have vast knowledge of and experience with electrictronics isn't logical.
Most things work with inverters but not all. I have some kind of a power supply, don't recall what, that says not to use it with an inverter. It's true you get 110(110,115,117,120) depending on how it's measured(min,avg,rms or max)) volts out of your home receptical but it's a sine wave. The ouput of a consumer inverter is a square wave.Square waves can cause noise or even overheating in some devices.
The other thing is that to get 110 volts the inverter draws 10X the output current to convert it. With a 20 amp fuse on you cars outlet that means your limited to ~2 amps for your devices.The vehicles system is ~13.5V so that's 27W. If you look at big inverters you'll notice they have battery clamps. 3 AC outlets from a cigarette lighter outlet is way optomistic.
An inverter may be a good choice for occasional use but probably better to keep everthing DC otherwise.
Make sure the inverter shuts itself off if the cars vehicle voltage gets low(i.e.when it isn't running). You could end up with a dead battery or even a damaged one.

Kind of nitpicking but cars are not grounded. Ground is literally the electrical potential of the Earth. A bad connection on the power or common(chassis) can cause noise but a sqeal is unlikely. The squeal is almost definately the inverter.

It's an earlier XB (2006) and only has the one outlet. When the car is in park, the shifter handle is literally about 5 inches away from the outlet. Having the double outlet plugged in, and angled up (adjustable) will allow some room, but then you are unable to grab the shifter.
I'll be driving to DC next Thursday, and wanted a way to power the GPS, G-Tab, e-cig battery charger, and whatever else my son decides to bring with us (NDSi, DVD player, his iPod touch, etc.)
To JJJustmee: The device does shut off when the car is off, so I'm good there. Also, the inverter itself has a fuse on it, so I assume that if overloaded, then the fuse will give on it, before it effects anything on the car. I don't necessarily plan on running all devices at the same time, more like, run the G-Tablet unplugged until the battery decides to start draining really low. The GPS will be running the entire time. Everything else may be charged for a bit, while other devices are no plugged in. I liked the design of this, becuase the car lighter plug is rather short, since there is a 3 foot wire leading to the AC/USB outlets, like a surge protector. It takes up very little room near the car outlet area. The other options that people posted will not work becuase of the space limitations. I could, and have (in the element) use the outlet splitter, then one double USB outlet, to be able ot handle 3 devices at once, but then we're talking about at least 7-8 inches of plastic pluggs sticking out, and into my shift lever...

What you're saying isn't quite true. Min, Avg, RMS, or Max are not accurate figures that you can toss out without testing. The Max voltage of a 120v system is 177v, The Root means square (RMS) would be the nominal voltage or 120v. Regardless, when you say it draws 27w you're doing the conversion incorrectly. The only way to change from one nominal voltage to another is via the resistance. So you max can draw 20A at 12v (240w), or 2A at 120V (or 240w ish) via and inverter (assuming your inverter is sized accordingly).

Said it for me.
If it turns off as soon as you turn the key off it means the outlet is switched. Will protect the battery but also means it can't be used for anythihng while the car is off. Good or bad depending on usage. What I was talking about is the device being able to shut off when battery voltage goes below, say, 11.6v. Fuse and circuit breakers only protect from too high of an amperage draw. If your system wasn't switched it could still dran the battery. Like if the inverter was left on overnight/weekend.
Sounds like what you're talking about could be ok for a trip. Use the USB as much as possible. Lots more effeceint than the inverter. If you actually mean fuse, get extra. If it's a circuit breaker you'll be good to see what does and doesn't work.
Found one on ebay

Just ordered it about $12:00 US delivered. I will let you know how it goeswhen I get in about two weeks.
Igo told me a week ago, that they don't yet have a tip for the Gtab/Zpad but expect to do so by the end of the month
Spec
Here you are some pics of Malata official Car adapter. Maybe you can find some thing to help.
Car charger
Just ordered this from Amazon. (can't link yet - crap) so "30W DC/DC Regulated Adaptor for DVD" do your own search
13.34 shipped. Many more bucks directly from batteryspace
Will post again after I test it.
more info: it comes with two tips, neither of which fit the gtab. I had a proper size tip in our tool box so will check voltages tomorrow.
This has better 12V DC regulation than the oem ac charger.
Guys
YOU DO NOT NEED AN INVERTER TO CHARGE YOUR G_TAB IN THE CAR.
ANY 12VDC (output) charger will work. They are a dime a dozen if you know where to look. Just make sure the tip fits, and is tip positive (symbol will look something like this)
12VDC @1A
(-)-C-(+) with a dot INSIDE the "C" that is connected to the (+)
The power supply controller will work down to 9V and up to 18, which is fine for the 10 to 14V you'll get from a car adapter. Just make sure it isn't a step down.
They should be like $5. You might have to bust out the soldering skills though if you can't find the right tip.
One of the things I was really excited about with the Lumia 920 was the built in wireless charging feature. Since the Nokia charging plate was selling for about 70 bucks (ouch) I decided to see what alternatives were available. I've tried two different wireless chargers so far with mixed results:
LG Electronics WCP-700 - This charger works great and I was able to snag it from amazon for 35 bucks shipped. If you want wireless charging but don't want to pay 70 bucks for one charger, then I highly suggest this model. You can get 2 for the price of one Nokia Charger.
Powermat 2x - I was hoping the community could give me some advice on the powermat. Naturally if you plug the powercube into the phone, it will charge just fine. BUT I noticed that if you put a charging plate on the charger and then put the 920 on top of it, the 920 will begin to go into charging mode, although when i tried doing that, it didn't really seem to be charging at any noticeable rate( I may have been taking the phone off the charger too frequently though). Does anyone know exactly what voltage and amperage the powermat wirelessly charges at? My concern is that the volts or amps will be off and damage could be done to the battery in my lumia 920. Any thoughts?
Good questions! I was wondering the same thing about the different mats out there.
What about the Energizer one?
Also, the LG one apparently beeps a lot...does it do so with the Nokia? When it finishes charging it turns off and lets the phone run off battery for a bit, then turns back on to top it off again, causing it to beep each time it turns on throughout the night. Have you noticed this?

From what I've read, the Energizer QI chargers will work fine with the 920, I just didn't get one since the LG model was a bit cheaper. The LG one does beep, although I haven't found it to be too much of an issue. When I place the phone on the charger, the LG mat will beep and show the green charging icon, and my phone will make the connection noise. I also think the mat will beep occasionally when the phone is charged, since it lets the battery drain a bit, then starts charging again, although last night it didn't wake me up at all while I slept. You could probably remove the speaker from the LG pad fairly easily, although from my experience, it's not bothersome enough to be worth the trouble.

Doesn't the PowerMat use a different wireless charging standard? I thought I read somewhere it wasn't the QI standard.
PowerMat is its own standard.
Not sure where you are, but the plate is $50 and the stand is $70 here.
Might want to try mail-order?
As for other plates, I have a few lying around, but I don't want to risk my phone trying them without knowing. I have 2 plates and a stand, so I am pretty covered.
Philips DLP7210B/10 also works with the Lumia 920.
I ordered a Palm Touchstone off Amazon for $6 and free shipping. I'll know in a few days when it gets here if it works or not, but I read somewhere that it should.
Sorry to disappoint you, but the Touchstone does not work. It makes the charging notification sound, but the battery still drains; it doesn't charge at all.
I have the Maxell Airvolt QI charger. It works but the phone seems to get warm unlike the Fatboy charger I use at night.

I really hope someone makes a 12v charging pad to keep in your car. Plug into the cig lighter and lay the phone on the "pad" somewhere in the car. I know the new dodge cars have it as an option now.

There's no reason why a 12v adaptor of sufficient ampage wouldn't work. Just match up the plug and polarity to the DC adaptor that comes with the charging pad.
But obviously a QI charger is not designed for use in a car. QI only recently release their guidelines:
http://www.wirelesspowerconsortium....ermarket-chargers-v-10.pdf?force-download=yes
It seems there are two current wireless charging standards: QI and PMA
Powermat are PMA, and this is a copyrighted licensed standard, i.e., Powermat will get revenue/license on each device. There is a limited trial in Starbucks.
QI is open, and I think a "free" standard. They have public charging spots in Japan, and Japanese handsets are predominantly QI
This is all just what I've recently read, so I'm not an expert or utterly certain it is correct, but it does seem that Nokia 920's are to the QI standard, and so any QI charging plate should work...?

Ooooo, my Edge has a little 'shelf' under the console that has a ribbed rubber bottom. And it has a 12v plug right beside it. I bet my husband (the engineer) might be able to wire up a charging plate. He would need to shorten the cord so it wouldn't flop around. But he's very good at that sort of thing.
This is a great idea! He works overseas but I think I have a new 'honey-do' for him on his next R&R. Thanks!

tabletop charging
I personally think it would be awesome to be able to integrate QI wireless charging into a tabletop. think about it, when you sit down at a table for dinner, you usually take your phone out of your pocket, right? what if you could charge it while you eat? why doesn't starbucks do this?:highfive:
I'm looking for an aftermarket charging dock similar to the Samsung but without the ridiculous price tag. Does anyone have any advice? I also was thinking of an idea for a charging adapter that I think should either exist already or be easy to make from existing designs.
I want to wirelessly charge my phone when in my car by simply dropping it into my cupholder in the center console. I was thinking, if there was a way to take an existing wireless Fast Charge adapter, and turning it into a ring or band (similar in size and shape to a Slap Bracelet). It would only need to be inserted into the cupholder, expand to the shape of the round opening, and when you drop your phone into the cupholder, it would begin to charge. If this product doesn't exist, is there a way to make it with current products already on the market?
I'm interested in something similar to this. My car has a little cubby that my phone fits in perfectly and I'd like to install a wireless charger directly under the panel that my phone sits on. My concern is the difference between AC and DC current which could be avoided by using an actual car wireless charger but I'm also skeptical about most of the wireless chargers out there.
The high power ones have fans. Under the cubby might not be enough air circulation to keep it cool, and could cause it to overheat or even catch fire. I'd avoid that.
I just bought a 3A charger from Amazon. http://www.amazon.com/Charge-Anker-...&redirect=true&ref_=oh_aui_detailpage_o00_s00 Look for Quick Charge 3.0 and make sure and get a compatable cable.
