OEM charger output vs. high output car charger

IIRC the stock wall charger is rated at 1.8Ah. But, what is the phone's actual draw? Does it ever get up there near 1.8mAh?
I'm just trying to figure out if a car charger with "only 1000mA" will be sufficient. I'm guessing that the OEM wall charger is rated well above whatever the phone might ask for, but as to how much, I don't know.
I'm actually looking at these two right now as they both seem to give a pretty high output for both Android and Apple devices.

My experience with other phones is that the phone draws exactly what the stock charger gives it. I'd imagine it's the same with this one. 3140mah is a lot of battery to charge.

I'd agree. I charged it the first couple days using the OGP wall charger and USB cable from my Nexus 4. It took all night. Switched the cable with the one in the box, and it charges in like an hour!

I have a 2.1a car charger, and the OGPro charges in exactly the same amount of time as the stock wall charger.
Oddly, it charges slower from my 2a Note II charger.

Which car charger do you have?
I'm looking on amazon and all of the 2A+ charges I'm finding are for Apple crap.

Im looking at all of the chargers from Anker on Amazon. It seems they have the best positive reviews of anything I've seen. Although the 3.6 watt (white unit with either 2 usb ports or one port and a micro usb cable) unit is newer than the 3.1 (black heavy duty), the black unit can give the full 3.1 watts to either port or split it amongst the two ports. And according to Anker, either port will work for Apple or android. They suggested i get the newer (white) unit, but i want to have the full 3.1 watts available to a single port for future h higher powered devices.

I'll have to check those out. I've been looking at this one, which has good reviews on it.

My concern with that one is that it gives a total of 2.1A. So if you charge your OGP using one usb port, there's only 0.3A left for the other port. The disclaimer at the end of the description says that if you are charging an iPad to not use the second port. I'm guessing that warning would also apply too us with the high draw OGP. It also states that the blue light gets even brighter in the dark. You might need to cover the led if it's too bright,but that's a personal taste thing,and it might not actually be that intrusive. Lastly, do you have enough room in your vehicle to rest both your phone, and the head of the charging device? I have a dual outlet 12v supplier in my car, but i bought one that has no cord. The two outlets are rigidly mounted right at the end of the cigarette lighter plug.

I bought a Griffin Powerjolt single USB at Walmart. It only charges at full speed using the OGPro's stock cable. Any other cable is slower, and the cable from my old S2 gives me a "Slow Charging" notification.
Anyway, this charger is just a stop-gap. I'm going to be hard wiring two USB plugs into my truck's 12v system (with some 5v regulators and an Add-a-Circuit).

I was looking at the 3.6A charger, here's the link on amazon.
As I expected, one port is for Apple and one for Android. This is very irritating because I need to charge my OGP while my fiance charges her OG at the same time on trips.
Can our OGP charge at full speed on the Apple port?
Edit: I just read that the kernal in Android 4.2 fixes this issue so we can charge in any USB charger, including apple chargers. I'm guessing LG devices still on 4.1 won't benefit from this update.

Shouldn't going to Settings > PC Connection > USB Connection Type and then setting it to "Charge only" force the device to see any cable as a charge only cable thus making it charge faster?

As per Anker, the Apple port will charge Android at full speed. I have not verified this myself as I have not gotten mine yet, but that's what I'm told, and expect. I'm waiting for their wall charger to come back in stock as the shipping will be free if l order both.

I ordered the black 3.6v version. I'll get it Monday or Tuesday since I have Prime.
Are there any apps that detect how much juice the battery is getting?

Same here. I've been using the charger from my old Atrix. I may get LG's charger out of the box tonight to see if it's any faster.

I just bought a 4.2 amp dual usb car charger, so I can charge my OGP and any other device without issue.
http://www.ebay.com/itm/42-Amp-Dual-USB-Car-Charger-iPod-iPhone-3s-4-MP3-HTC-/320779507652

I just got the amzer 3.6a charger and sure enough I get the "slow charging" on the apple port. I'm going to sacrifice a usb cable and re wire it so it'll work for now.
Can't wait for Android 4.2 to fix this issue.

I just made the charge cable linked in the post above. It works like a charm
I also purchased This wall charger which works perfectly fine with our phone on both the "A" and "NA" port.
I'm willing to bet this car charger made by the same company as the one linked above will work also.

Car Charger

Anyone find one that works well? I got a Cellet retractable micro use charger last week, and it charges my Motorola Electrify M just fine as well as my Gen 1 N7. No dice on the N7 FHD.
Ideas?

hii well as if you are looking for a car charger you can check out the huge collection of car charger for N7 at Fommy

Thanks..!!

I just got one of the sea few day ago:
http://www.amazon.com/gp/product/B00B8M4IMK/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1
It has dual USB ports. One is marked Android the other Apple. The apple port if specifically designed for apple devices (iPhone 5, iPad).
Individually each port can do about 2 amps, or 3.6 amps total if both are being used. The Apple port will charger other devices slowly with standard Data sync cables or full speed with a charging only cable (no data).
Basically with a Charging only cable you could charge two device, one at about 2.1 amps max and the other at about 1.5 amps max (3.6 total amps).
I have two dedicated charging only cables coming that I plan to keep with this car charger so I can charge my phone and tablets on to go.

I tried my Nexus 2013 in my dual Sprint car charger that I got from amazon (Technocel MV9MCDUO-SP OEM Sprint Car Charger - Black with USB Port) and I'm getting a really good charge for my Nexus.
I even tested my phone charging in it's USB port while the Nexus was charging on the main cord and both seemed to cahrge jsut fine.
If I just charge my Motorola Photon on the main cord it charges faster than any AC adapter or car charger I've ever used.
I highly recommend it.
I can't post links yet but its $6 on Amazon.. search for... Technocel MV9MCDUO-SP OEM Sprint Car Charger - Black with USB Port
Fommy says its compatibale for the Nexus 7 2013 too but it's $19.95 there.
(Sprint® (OEM) Micro USB Vehicle Power Charger PLUS for Google New Nexus 7
SKU: 89356
Price: $ 19.95)

Anyone had any success using a wireless charger in the car?

I suppose that would work, a 2 amp or 1 amp car charger should power most QI chargers.
Not sure I see the point though, I see two issues:
1. Wireless charging is less efficient and slower (better suited for the desk or night stand).
2. There's a good change the device will move around while driving and not charge if the coils are not aligned properly.
You could try a modify a car mount to hold a wireless charger, but you still would have the slower charging issue, withc may not really be an issue for some.
I have however seen a car mount that holds the phone and has a opening to hold a round QI charger, but wouldn't work for the N7. See here:

What I'm thinking is, taking the back of a slide-in type cover and hardwiring the wireless charger behind it. A slide in type cover should minimize any movement/alignment issues.
Then affixing the entire assembly over my existing NAV screen in the dash with the wireless charger hardwired to the car.
Then, I can slide in/slide out the Nexus as desired, and not have to worry about fiddling around with the Micro USB connector.
I'm not concerned about charging efficiency, more about maintaining power. A 2A charger at 60% efficiency should provide me the 1.35A that the Nexus 7 needs. When needed I can remove it and fully charge it.

Which USB car charger are you using with Nexus Qi charging pad?

I have the latest nexus Qi charging pad along with this USB car charger
http://www.amazon.com/gp/product/B0088U4YAG/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
its dual port and has one for apple and the other for non apple phones.
the non apple port has 4.2amps output max.
it charges my Nexus 5 and Nexus 7 easily and fast and shows as AC charging.
the first few weeks i was able to use this car charger with the Nexus Qi charging pad no problem but now it doesnt work and the charging pad shows a RED LIGHT which means its not getting enough amps.
when I plug that car charger directly to the Nexus 5 and 7 it still charges as AC easily and fast no problem so it boggles my mind why it just stopped working with the charging pad.
What USB charger are you guys using that is still working with no issues with the charging pad?

Anyone?

I don't use it regularly with the wireless charger but I have tested it and it worked in the past...
http://www.amazon.com/Anker®-Dual-P..._18?s=wireless&ie=UTF8&qid=1406656736&sr=1-18
For some reason the black model is no longer available from Anker, so it's very expensive compared to the white... hopefully they get it back in stock.

Charging pads only need around 0.7 or 0.8A since they only output 0.5A so you don't need anything special for them.

Wireless charging

Anyone using wireless charging on the MI3? It's only possible with a receiver, btw, it's not built in.

I am curious has anyone tried using a wireless charging add on and know if it works properly?

I'm a writer for Qiwireless.com and I use my Mi3 with a universal wireless charging receiver to charge it.

I saw something here: facebook.com/MiuiCzechSlovakXiaomi/posts/10152284167068959
Manufacturer named Lencow doing this type of chargers for MI's. You can find the net for the price.

is it for real that mi3 supports wireless charging??

Note, WITH a receiver. A receiver is a piece of hardware which sits under the base of the phone, and is connected to the charging circuit. Just google the term.
You'd have to be really motivated to take your phone apart, just to attach that. Without considering the space that module would need vs the available space inside the phone, which is pretty slim to start with. Actually with a metal phone back, I believe the module would have to sit outside of the phone, between the plastic cover and the back - so the phone back would not be flat.
I have had a Nexus 4 with wireless charging for the last 2 years, and I rarely use the wireless charger I bought:
- charges slower than a wall charger
- if you pick the phone up - as we all do - you stop charging and additionally multiply the number of charging cycles.
Cables are not as cool as a Qi pad, but a Qi pad also needs its cable...
Anyway, out of the box, the mi3 doesn't do wireless charging - just confirmed that with my wireless charger

stupid!!! pls improve yourself bout the 'Electronic Science and Technology' knowledge~ don't ask such an idiot question!!!

Qi Charging through Wireless Charging Receivers

Has anyone tried this? To circumvent AT&T using PMA instead of Qi or add wireless charging to any other LG G3 variant.
Can't post Amazon link showcasing the product for I am new here but here is how it works. It' uses the phone's USB port and you have the receiver connected to a wire and when the receiver touches the back of the phone you get wireless charging.
Do simple Amazon search for wireless charging receiver and you will find it.

I don't think you have how it works quite right. This plugs into the microUSB port and then sticks permanently to the back of the phone. You then need to put your phone, with this device stuck to the back, on a Qi charger. Just touching this to the back of the phone does nothing by itself.

People have successfully used these on the D850, however, its a hit and miss with the quality of the qi sticker. There's an OP discussing this if you search for it.
