Car Charger Question

Ok, so I took my Inc on it's first run yesterday as a full-time GPS. It sat in the Verizon dock, plugged into my Griffin dual-port USB cig. lighter adapter.
It made the entire 3.5 hour trip, but when I got there, and removed the phone from the charger, it was at 9%. It had started at 100%. So, obviously, the 5V .5A that the Griffin outputs is not enough to run the GPS and at least maintain charge.
Does anyone know where to get a 5V 1A car charger? Unfortunately, most manufacturers don't even list the amperage output of their devices either online, or even on the packaging!
Thanks,
Doc

sounds like you might be best off with a power inverter and a wall adapter. or you could buy a car that has a 2 prong outlet in it like mine

As an EE that's really inefficient. Belkin USB Micro Charger does 5V @ 1A max. It's marketed as an iPhone/iPod car charger but it does work for the Incredible since it doesn't have any fancy charger lockouts. There is also a 2 output version with a 1A and 500mA plug.

2.1a charger for N7

Can I use a 2.1a cigarette plug on the N7? Or can someone recommend a suitable car charger (dual usb)?
Sent from my Nexus S 4G using Tapatalk 2

As long as the voltage output is correct it sgould be fine. I reckon 2.1Amp is plenty. I've not had much luck with 2Amp+ cigarette lighter adaptors, the few I've had have always ended up causing radio interference.

y, voltage matters much.

I've got a dual-output cig plug that has a 1A port and a 2.1A port. On my N7, it charges fine off the 1A port but doesn't charge at all off the 2.1A port.
For comparison, from the 2.1A port my Galaxy Nexus phone only recognizes it as "USB charging" so only pulls 500ma. 2.1A usually means it's got the special ipad circuitry and most other stuff won't pull more that 500ma from it. I stick to 1A chargers now.

From a purely electrical stand point the amps is less important then the voltage. You simply always need a supply with more amps then your device will draw. Unlike voltage where you do not want to have a difference in the number as long as the amps number is higher you're fine. If you have extra amps it doesn't use them unless it can pull them. But as timropp said you'll probably find it's designed to charge at 1A (ac charger) or 500mA (usb). A 1A charger has some resistors on the data lines which tell the device that the charger can supply 1A. Without those whatever is connected is assumed to supply at most 500mA and the device limits itself to pulling that much.

Resistors are not needed. I just solded the 2 USB data pins together and my Galaxy Nexus recognizes my car charger as a AC charger.
But unfortunately i don't think there is an app or variable that can tell me the actual amps the device gets from the charger.

Anker 5-port wall charger

Just got this from Amazon. Charges the HD+ just fine from the USB port labelled "Samsung Tab".

Wait, it doesn't charge from the iPad output?
The original nook charger has 2A output, so it should be finde with the iPad output 2.1A too :S
// my oyo ebook charger charges it too and also has only 1A.

No, it does not charge from either of the iPad outputs. It's not just a matter of sufficient amperage; I believe the problem is that the wiring is slightly different on the Nook cables (this has been discussed extensively in this forum) than on many other devices.
The Samsung output is rated at 1.3A. This means that it will probably charge a little less quickly than a 2A charger but since I want one unit that will charge all of my devices when traveling I'm willing to make the (small) tradeoff.

Car Charger For Nexus6

Hello,
I have the following charger in my car. Can I use it to charge my Nexus6 ?
It has 10 Watts per port, 2 X 2.1A, 5V (voltage not sure).
http://www.belkin.com/my/IWCatProductPage.process?Product_Id=652450
Please suggest.
Thanks.

Why do you think you couldn't use it?

I thought of checking with you, if the output of that belkin (current, voltage etc.) matches with the Nexus6. I understand that the phone will draw only the current that it needs (1.6A) from the charger. But not sure about the Voltage. It doesn't show the voltage in the specs also. So is the Nexus6 support all ranges of voltage - 5V, 9V and 12V ?
Please suggest.
Thanks.

Well if it is a standard USB connection on the charger and works with other devices, you can bet that it is 5v.

Yes, mostly. I have this charger with me and don't want to buy another one, and I have 2 phones to charge while travelling in the car.
One question: Whether the Nexus6 support all ranges of voltage - 5V, 9V and 12V ? I have seen them printed on the inner side of the Turbo Charger. But want to know more about how it works.
Thanks.

The 9V/12V on the standard charger are for Qualcomm's Quick Charge. The phone will charge from a standard computer USB port outputting 5V/500mA (albeit very slowly) if you wanted to. The phone will draw as much power as the charger can output for a given voltage, up to the limits programmed into the kernel for the charging chip. Either the charger or the phone could be the rate limiter, but any charger that you can have a microUSB connection to plug into the phone should work.

charging rapidly with aukey quickcharge 2.0 wall charger and type c adapter

so this combo is working for me:
http://www.amazon.com/gp/product/B010UT6Z3Q?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s01
http://www.amazon.com/gp/product/B00W98IQ5M?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00
the latter also allowed me to fastboot oem unlock.
so battery is at 59%, homescreen says 14 minutes till full.
cheers

can you please check with Ampere or GSAM for the charging speeds that you achieve?
does the device say fast/rapid charging?

Interested to hear the results from Ampere or GSAM as well

i cant get a good handle on how ampere works. it keeps measuring, takes forever, and fluctuates a lot.
with the aukey combo, i got 1830/2050mA @ 4.14v, at 53%, 37.7c
took it off charge for a while and tried again with the stock charger:
with the stock charger, i got 1850/1860mA(min/max) @ 4.159Vat 61%, 30.7c
I will try again at 50% today if I have time but I am pretty pleased with my little aukey combo. It was cheap.. I got it when there was a 7 dollar coupon floating around.

FYI, believe this is the same charger : http://www.amazon.com/gp/product/B00QEX83LA/
Use Promo Code DBVITSZB to drop price to $6.99
Can only purchase 1 at the discounted price.

Yep that would be the one. charging at 1800mA is not the fastest that the phone can charge at though. I'm going to hold off for the ones that enable the full speed of charging

For 7 bux I think it's still a good deal for someone who doesnt have a spare to use

From the product description, you are only going to get 2A out of the charger. 5X doesn't do QC2.0, so you will only get the output at 5V, which for this charger is 2 amps.
Specifications:
Input: AC 100-240V
Output: 5V/2A, 9V/2A, 12V/1.5A
Dimensions2.69*2.05*0.87in)(68.5*52*22mm)

But some Aukey chargers with AIPowertech like this one "charges all non-Quick ChargeTM 2.0 phones and tablets at their normal speed (up to 5 volts / 2.4A Max)with AIPower Tech Technology."
I've got the charger, just not the cables... so haven't been able to test.

I tested Aukey PA-T2 wall charger QC2.0 port ( orange one) on a Sony Xperia Z3 compact tablet
I recorded charging current up to 2.7Amp with the Aukey USB cable and up to 3.0 Amp with the Sony USB cable !!!! far more than the 2.0 Amp level current Aukey specifies......
The voltage - current output test show that the voltage stay in the 9.0V range with current up to 2.4Amp then fall down very quickly. It seems that the voltage stay at a value enough to deliver up to 3.0 Amp charging current to the tablet ....
Detailed test are here (http://78michel.unblog.fr/?p=860 in french....)
Current values where obtained from BMW recordings

Using the
Aukey Quick Charge 2.0 18W USB Turbo Wall Charger
And

Getting Charging Rapidly. The juice isn't nearly as good as the stock charger, but this is the first combo with a USB-A to USB-C cable that I've gotten the Charging Rapidly notification.

LOL, thanks... but that doesn't really help this 5X cause. Given that there is no quick charge on the 5X, it'll remain at 5V. The question is whether it'll pull more than the 2A or 2.4A specified on these chargers at 5V on a 5X.

Aukey quick charge 2.0 behave like a standard charger when connected to a non QC2.0 compatible device. The output voltage will stay to 5V so the current level will be very sensitive to the quality of the USB cable and limited by the maximum current the device will afford.
In practice it is very difficult to reach 2A charging level ( even if the charger is able to deliver such current) with a voltage output of only 5V , due to losses in cables and connectors
From my experience the higher current charging level I obtained was with a Samsung wall charger refence EP-TA10EWE which deliver an output voltage of up to 5.5V at 1.9A ( nominal voltage is claimed at 5.3V)
I got 1.7Amp charging current on my Nexus 5 while with the Aukey QC2.0 the current was only 1.1 Amp in exactly same conditions ( these recorded data are also reported in my blog .....in French.....)

Thanks, didn't think to look at the link.
I wonder how older phones like the NA Galaxy S3 and Nexus 4 that both have QC1.0 ([email protected]) compare to the charging of the Nexus 5.
I'm curious as to how you did your testing, as I'm going to try my own testing once my cables come in. Did you drain all your phone's battery to 0 before performing each test? Phone airplane mode vs off? I also think that all tests must be done in relation to time, especially since the charging profile changes as the phone charges. I'm also curious as to how the non QC port on the Aukey performs, since it's spec'd at 2.4A @ 5V.

All tests are made with battery drained to zero before starting , and a complete charge is done in each conditions. That way I can check that the full charging time is logically related to the recorded current values. The current is recorded during the complete cycle at a frequency of one value per mn.
The air plane mode was off.
Aukey QC port and non QC port are slighly differents when connected to non QC2.0 devices :
QC port delivers 5.1V in open circuit, the voltage encrease to 5.2V at 2.2Amp, on the contrary the non QC port delivers 5.2V in open circuit and decrease to 5.1V at 2.2Amp. I did not test them at higher current level.
I did not tested Galxy S3 or Nexus4 , but I beleive that a charger like the Samsung EP-TA10EWE will deliver them the maximum charging current they are programmed to accept, as obeserved for the Nexus 5.
I got the same charging current curve I recorded with Nexus 5 and Samsung EP-TA10EWE, with other set of charger and cable. This means that this charging curve is defined by the Nexus 5 inner program , not the charger characteristics. The problem is that we never know which is the max current curve internally programmed for each smartphone...... so it could be a long way to find it.......
