There are 2.1A usb adapters, but I don't think microUSB can take advantage of it. The one you linked is a 1A, which is the same as the wall charger HTC gave with the phone. I'm currently using a 1A usb adapter in my truck.
Ok that's probably what I'm looking for then. Are there wall chargers greater than what came with the phone that I can take advantage of?
Your best bet would be to try the USB adapters made for iPads. The Apple products can utilize the 2.1A chargers with their sync cables, but I'm not sure if a microUSB cable can though. I have some 2.1A wallchargers from some of my Apple products, I'll test them later and let you know what I find out.

The Motorola rapid chargers rock.
Guys, unless you mod the usb adapter 5V spec, you aren't doing squat with a "high power" adapter. The device has an input impedence that will draw a certain amount of current at 5v., and that's it.
Standard battery: 1400 mAh
Time to charge: 4 hrs (according to manual)
That's 1400/4 = 350 mA.
Most adapters on the market spec more than that, they're usually 500 mA or above. And again, unless you boost the volts, you're not going to be able to push more than 350 mA or so.
So don't waste you're money.
On the other hand, if your going to share a car outlet with another device like mp3 or ipod, then yeah, you'll need a higher output, two port, adapter.
Edit: It just occurred to me that if you're using the phone heavily while charging, then yeah you may need more than 500 mA. My currrent widget shows the phone can draw another 250 mA or so during use. That plus the charge totals to around 600 mA. But depending upon design, the phone may not be able to pull in all 600 mA. A test with a current meter would be real interesting.
The charger shipped with the Thunderbolt is a 1 Amp charger.
If I use a 500 mA charger the Current Widget shows a +450mA charge current. However if I use the 1A charger, I get a charge current of about +850mA.
Given that the google navigation gobbles over 400mA when running, you need a car charger with greater than 500mA capacity of you want the phone to charge at the same time.

You're making the incorrect assumptions that the charging rate is constant, and charging is 100% efficient. Li-ion batteries can be charged at up to a 1C rate (i.e. 1.4A for a 1400 mA cell). Add the power drawn by the phone itself, and a 1.8 Amp charger might not be unreasonable (1.8 A is the specified limit for micro USB connectors). Whether the phone will actually do a maximum rate charge, I don't know.
This, from a TI Application Note (Google for SLAA287, board won't let me post links):
A Li-Ion battery charging process consists of three stages:
· Slow Charge: Pre-charging stage using current of 0.1C
· Fast Charge: Constant current charging stage using current of 1C
· Constant voltage charging stage
During the slow charge stage, the battery is charged with a constant low charge current of 0.1C, if the battery voltage is below 2.5V. The slow charge stage is rarely used during the charging process of a Li-Ion battery.
The fast charge (constant current) and constant voltage charging are the most important stages during a recharge process. Most Li-Ion batteries have a fully charged voltage of 4.1 or 4.2V.
The battery is first charged with a constant current of 1C until a battery voltage reaches 4.1 or 4.2V. The firmware continuously checks the charging current by sensing the voltage at the current sense resistor (Rsense) and
adjusts the duty cycle of PWM output from the MCU. The battery's voltage is checked frequently.
Whenever found the battery's voltage reaches 4.1 or 4.2V, the charger will switch to constant voltage charging mode. The battery is then charged with a constant voltage source at a fixed battery voltage of 4.1 or 4.2 V...When the charging current falls below 0.1C, the charging process must stop.

I suspect you need to find one which properly follows the USB Battery Charging Specification. That link is to the most recent version, which came out on 7Dec2010 (remember Pearl Harbor!). Version 1.1 is easier - a Dedicated Charging Port is indicated by shorting together the data lines (the two middle conductors on a full sized USB connector. By doing so, it indicates the device may try to draw up to 1.8 A of current (although a dedicated charging port is allowed to limit the current to less than that, it must provide at least 1.5 A).
I bought a cheap USB hub with 5 ports, used an exacto knife to cut the traces going to the data lines (the middle two) on all the ports, and then shorted them together on each port. It's now no longer a USB hub, but a USB charger with 5 ports I can used to charge stuff (phone and Bluetooth, quite often). The AC adapter which it came with does 2 Amps. My Thunderbolt says "Charging (AC)" when plugged into it.
So, if you can open up one of your adapters, just solder a jumper between the middle two contacts (make sure they're not connected to anything else).
Just got the Rocketfish premium microUSB at Best Buy and it has a captive coiled cord and a USB port. TBolt says "AC plugged" and reads +670 mA.
Good choice on the Motorola Rapid Charge - I've burned through 3 other cheap car chargers trying to keep my phone alive while using Google Nav and this is the first one to work!

One additional thing. Learned that the hard way.
Bought a HTC car charger. HTC supplied cable to that HTC car charger. Original HTC car charger on this charger sucked... despite showing AC charging
So look first when you charge if it says USB charging or AC. And then check how long it does to charger. Change the cable to the original one supplied with the phone if it's more as on that original stock charger

Well charging doesn't have 100% efficiency so a 1a charger won't charge at 1a, so a higher charger means you should get to the 1a limit but it's not going to reduce charging times enough to notice.

A charger rated at output of 1A should be capable of outputting at 1A. Of course, it will draw a little more power from the input than it provides to the output.
When charging, during the first phase (constant current) the maximum current draw is typically around 1A, for up to about an hour, then it drops off quite quickly when it moves to the second phase of constant voltage.

Can a qi charger charge the nexus 5 when data and GPS is being used ?
Will it charge or will the battery drain?
Sent from my Nexus 7 (2013) KitKat 4.4.2
Power consumption during data and GPS use varies depending on what apps are used, signal strength ect... so there is no definite answer. In general, I notice slight battery drain when using navigation when on wireless charging. Google's nav app uses more power than the 500 mah the Qi charger provides but the drain is much slower than on battery alone..

500 mA was an estimate, individual results vary. Take into account wireless charging has an efficiency of 70-80%, so a charger with a 751mA output would effectively charge at 600-526mA. Add a phone case and/or imperfect alignment charging efficiency drops even lower. In real world use my 750 mA qi charger charges at about the same rate as a 500 mA USB port.

Oh yeah, I took that into consideration already, which is why I gave such an exact number. I got 751mA from a 5V/1A output rated Qi charger.

As long as the Qi charger you buy is rated as 5V/1A output (which is almost all of them out there, including the official nexus wireless charger, tylt vu, etc.), you should get around the charge rate I mentioned if it's maxed out fully. So people buying the expensive Qi chargers, are not getting any speed improvement over the cheap one I bought. Might look a little nicer sure, but I'll gladly keep the $20 - $50 in my pocket instead. If you want to read my whole post, I linked it.

This is strange, I used the "Current Widget" app as well. . I'm currently using an Anker Powerbank, it's a 6000 mAh battery with a built in Qi charger which shows an average 500 mA charge rate. I also have an official Nexus 5 Qi charger that also shows about 500 mA charge rate. When connected directly to the Nexus qi charger wall adaptor I get a 1560 mA charge rate. Thanks for your data, this makes me wonder how accurate "Current Widget" app actually is since our results differ so much.

Yeah, I used CurrentWidget as well, it's a pretty close estimate, but it won't be 100% accurate. I just didn't want to tear things apart and use a multimeter to take readings. Make sure your CurrentWidget update interval is set to 1 so it gives you live updates. Then you just have to give it a few minutes to stabilize (it will always fluctuate though) and watch for the consistent highest reading over a period of 5 to 10 minutes to be as accurate as you can. For my readings, 751mA kept popping up over and over again but never higher, so it was reasonable to say that was the max my Qi charger was capable as long as it was receiving ample power itself.
The charge rate will also vary depending on where in the battery charge cycle you are recording. At the beginning and end of the charge cycle, it will not charge at full speed and will slow down the charge. This is to protect the phone and the battery. For best range of recording, try to take your readings when your battery is charging around the 25 - 65% full mark, that way you can be pretty confident that your phone/battery is allowing the charger to charge at full speed.
What is your Anker Powerbank output rated as?
Also, was that 1560mA a consistent reading, or just a spike?
Most likely it'll go down if the screen is on, if the screen is off, it may stay or go up extremely slow.
Thanks for the replies.
If the charge will go down when screen, data and GPS are on.. Then it's not really a suitable for a sat naval replacement.
Looks like I'll need to go with a cable.

Don't forget with GPS and other things on your temperature will go pretty high and could reach 45C where wireless charging practically turns off and your charger will only try and maintain the current battery percent. At least this happens to me monitoring it using battery widget.

I haven't gone so far as to install current widget, out even better battery stats, but I have taken some long trips with navigation and music streaming, screen on the whole time, and with the cheap Chinese 'c1' car mount, I always arrive with more charge than I left with. Maybe this is because I live in a cold climate, and the charger does not stop because of excessive heat.

The Powerbank Qi output is rated at 500 mA. The 1.8A wall adaptor gives a fairly consistent reading above 1500 mA.
I set faster update interval and found the following averages. (Battery @ 50%)
Nexus Qi 1.8A wall adapter: 1500-1605 mA
Nexus 5 stock wall adapter: 900-1000 mA
Nexus Qi charger plate: 450-740 mA
Qi Powerbank 500 mA: 300-476 mA
PC 2A USB port: 550-750 mA
It seems the Current Widget rates the summarized magnitude of draw from the battery. For example having the screen on and higher brightness will subtract from the measured charge. To negate this I placed the phone in airplane mode, screen off and set sampling to 5 s. Then after 10 s turned the phone on to view the last sample taken with the screen off.
Looks like you were right, a 750 mA rated charger factors in transmission losses. The Official Nexus Qi plate puts out 750 mA max. The Powerbank puts out 500 mA as labeled. The 1.8A wall adapter was surprising though. Anand's article stated the max charge rate was 1.2A but the 1.8A adapter clearly exceeds this rate.

That is interesting. My finding mirrored that of Anandtech. I used both the 1.2A stock adapter, and a 2A adapter and I was not able to increase my charging speed at all. It stayed at 1053.
Can you check the plug to see the voltage of the Nexus 5 Qi adapter. Is it 5V?
Could you guys recommend me a wall adapter?
I heard that i should get a 1500 mA one, but the best i found on amazon is Belkin Universal USB Wall Charger EU which is a 1000 mA ( i'm not allowed to post links yet, but if you search it it's impossible not to find it). I have to tell you that i can only buy it from the UK and that it needs to be a standard EU plug.
The one amazon.de sent me charges fine, the only issue is that it turns on my device if i try to charge it when it's off. The charger is a 5v 1A.
My iPhone 5S wall charger is also a 5v 1A but it "behaves better" i guess, because when my moto G is off wheni plug it to the iPhone 5S wall charger it doesn't turn on my phone automaticaly, it charges fine and the moto g only shows the battery image on screen.
Both charge ok (1A 5v), but if i want to charge my phone when it's off i guess some chargers won't be able to do that. Maybe it's an voltage accuracy.

Additional amperage does not harm the device, only incorrect voltage will. The phone will only draw as much amperage as the charging chip allows.
Having said that, keep in mind that quick charging will wear out the battery faster than a slower charge.
I'm using a 750mA, 5V Blackberry charger for mine - from empty it takes about 2hrs 45mins to fully charge, so a higher amperage should be pretty fast. Doesn't boot the phone if the phone is off.

In case anyone is wondering whether the old Apple wall charger is working or not (the one from circa 2007. I broke my other decent wall adapter...), it's working almost perfectly. It's correctly recognized as wall charger and ~1A is drawn from. That's quite surprising, It had always been wrongly detected by all the phones I tried to charge with it. The only drawback is that the device can't be charged when off, the device will simply boot as soon as it's plugged. This doesn't happen with proper wall chargers (at least on JB, I don't know if something changed with KK).
To know if a wall charger is detected as such, dial *#*#4636#*#* and see if it says "USB" instead of "CA" in the battery informations. Usually USB means lower current (~500mA) and kernel wakelocks (not always this one, it depends on how the charger is detected). That's not good.
You can also get the amount of current flowing though the battery using CurrentWidget (look for it on the Play Store) or reading the files in /sys/class/power_supply/battery/.

The Asian dual sim version comes with a charger with a hard wired cable, rather than a micro USB cable (and interestingly, its only got 2 wires connected from what I can tell). Its 500mA, and mine uses a UK plug. I've also tried it with a HTC charger (the moto charger has a VERY long, unwieldy cable) thats also 500mA and it works too. There's no real need for a higher amperage, and it does tend to charge pretty fast.

I know this phone is Quick Charge 2 capable, but does that apply only to high voltage charging, or also to standard 5V?
I ask because I bought a 3.1A charger, and though the phone was almost dead, it didn't charge any faster than the 1.8A charger that came with the phone. Is the charger defective, or will this phone just not draw 3.1A at 5V?
QC2.0 is 9V at 1.2-1.3A.
Normal 5V is at around 1.7-1.9A only.
It will not draw anything more than what's above. FWIW, IMO, QC2.0 doesn't make a huge difference

QC is a protocol for allowing a maximum possible current draw at a predefined voltage. Just because you have a higher possible current supply from a charger it doesn't mean that the G4 will draw more.
E.g. G4 can only draw 1.8A a 5V. If you use a 1A charger, it can only draw 1A but if you use a 2A charger it will only be able to draw 1.8A and not the full 2A.
This phone is **** at charging 1% every 3mins at best. I'm at 44% 23 degrees Celsius and it says 2hour 4min to 100%. Ampere shows its only drawing 480ma on a 2A charger. Three cables.. Note 4 cable, Stock cable and a high quality third-party cable all the same. The cables work fine as they charge to Note 4 quick and a Tab 3.
I give up. I even put this LG poss on ICE to 18 degrees Celsius but still same crap. Night charging for me then. Even Note 4 quick charger can't help it.
Nice phone for sure but I'm going back to Samsung next upgrade, sorry LG.

What. You're using a **** charger. Get a proper charger. I know because I've tried mine on a **** charger, a Samsung Charger and an ASUS QC2.0 Charger. Nobody has the problems but you.

It does sound defective, unfortunately. Mine charges at up to 1%/minute, and that's without a QC 2.0 charger.
I use LG stock charger and a third party 2.1A charger to charge, Ampere shows that it has around 1000 mah. Apart from the charger, the charging cable quality do affect the result too. Try to swap cable and test again.
IMO﹐stock charger with 5V 1.8A can charge quite fast with 2+ hours to fully charged from 0 to 100%, no need to go for QC2.0.

I have found that my Original Samsung 2.1A charger sucks for the G4. Somehow it knows its a Samsung and doesnt want to provide anything over 1A. That charger charges at 2A my Galaxy S4. It takes like 3-4 hours to full charge from under 15%.
My LG G4 charges fkn fast with the original one and a Tronsmart QC charger. 1% every minute.
