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?

Nexus 7 Doesn't Work With Third Party Chargers?

For some reason my new nexus 7 only works with the oem charger not my Galaxy S4 charger or other chargers. Anyone else have these issues?
Sent from my Nexus 7 using Tapatalk 2

Make sure it's the correct voltage and amperage. The oem charger spits out something like 1.3A. A lot of usb phone chargers output less than 1a

my S4 charger works

S2 charger works also.

As does the S3 and N7 Gen1.
So long as it's 1A or greater it'll work at about the same charge rate (1A = slower, and anything over 1.35A won't charge much faster).

I invested in this a while back...best charger I own....

It didn't work on a charger I had that had a "special" cable that only provided power and ground. When I used a normal USB cable, it worked fine, so it apparently wan't to see something more than just an open connection on the data lines before it will charge.

Its worked on any charger I threw at it including the iPad charger with a HTC cable. Wireless charging also works great with the Nokia one.

Anyone tried using the Apple 12W 2.4 apm charger?
Is it ok to use more powerful charger than the one it ships with?

More capacity charger won't be a "problem" as the device determines how much power to pull. Lesser capacity charges can sometimes overheat if not designed well.
Often devices capable of charging faster will only go into that mode if they detect the charger is capable of doing so. Since the way they determine this is not standardized, sometime high capacity charger charge slowly. This could be caused by something on the charger side, or even the cable being used.
Worse case of using a higher capacity charger is it won't charge at all, but that is pretty rare. Often it will charge, either at a slow or fast rate.

Stock Charger or 2.1 Amp Charger

My question is would using a 2.1 amp wall charger over the stock charger pose any danger of damaging my Flo?

The charger spec just lists the max output. The tablet is the one that decides how much current to pull. So it is safe to use the 2 amp charger.

At this point, I don't think it has been determined. Install a battery monitor to see if it draws more current with a 2a supply over the stock 1.3a.

I am living in Germany so I don't have a Nexus 7 yet. But the charger of my mobile phone is broken and I would buy the 2amp charger, if it charges faster because I can use it with my Nexus 7, too.

There is something to be aware of when buying a 2a supply. The original Nexus 7 required the data pins (2 and 3) of the charger to be shorted in order to draw full current (don't know if the new one behaves similarly).
The majority of usb chargers out there are designed with Apple products in mind, which shunt a resistive load across these pins to tell the device how much current is available. The result of using the original Nexus 7 with these chargers is that the device only draws about an amp.
My experience has been that HTC chargers have the correct pins shorted, while Monoprice's do not. Your on your own with any other brands. You'd need to measure those pins with an Ohm meter to be sure.

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.

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.

Looking for a full speed car charger

I'm looking for a charger that will charge my Nexus 5 at full speed. I've tried a Griffin charger as well as a Monoprice charger and both are recognized as Charging (USB) by my Nexus 5. I assume they are designed for "proper" use with an iPhone, which I know can cause those issues. I am aware of the option to short the pins on the charger, but I would really rather buy one that works properly out of the box. Does anyone have any recommendations? I searched, but everything seems to be able using a wireless charger in your car.

Those two look like they are very high profile chargers. I know I didn't specify this, but I would prefer something a little less bulky. Also, they are under 1A while the Nexus 5 charger is 1.2A. Still better than the 500mA I'm getting currently.

I use the 18W 3.6A version of this Anker Car charger. But seeing as the 24W is $9.99 while the 18W is $8.99, might as well get the higher output one (supplies one 2.4A Apple port, and one 2.4A Android port). Here in Canada the 18W is $19.99, 24W is $21.99....
They have full Android support, so it allows full speed AC charging if you have a good USB cable. They also have versions with a built in cable, but I prefer to use my own because if the built in one breaks, you're kinda screwed.
The 18W 3.6A car charger I have charges the Nexus 5 at around 1100mA (with a good USB cable). That's perfect to still charge the phone while simultaneously using navigation, streaming music, etc.

Have you tried different cables? I'm finding the quality difference between cables makes a difference in the charging rate.

I bought an att one years ago and it's the fastest charger I've ever used in my car. You can get it on amazon for about $8 shipped.
