2.1a charger for N7 - Nexus 7 Accessories

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.

Is it Safe to charge Note 2 with other device's charger...?!?

My Note 2 charger says....
Input : 150-300 VAC 50-60Hz 0.35A
Output : 5.0V = 2.0A
Can i charge it with with following chargers....?
1. Note 1 Charger
Input : 100-240 V 50-60Hz 0.15A
Output : 5.0V = 1.0A
2. Iphone 3G Charger
Input : 100-240V 50-60Hz 0.15A
Output : 5V = 1A
3. Logitech Harmony Remote Charger
Input : 100-240V 50-60Hz 180mA
Output : 5V = 1A LPS
So can i Safely charge my Note 2 with any of the above chargers ? Or will charging with any charger Harm/Damage my Note 2's battery/internal components...?
Thanks.... :fingers-crossed:
As long as the Amper on the charger you use is lower than 2 there is no risk.
Voltage should always be the same or else it will damage your phone. (5volts = USB standard voltage)
If you use a 2,5 A charger the note will charge faster but will heat and damage the battery.
If you use a 1 A charger the note will charge twice slower than with the 2A charger but this charge will last longer because slower charging gives a little better battery life When I charge the note on USB 2.0 (0.5 A) / 3.0 is at 0,8 ampers it takes a whole night to get around 90% but my note lasts usually a little longer than when I fastcharge with the stock charger (one gets lazy to charge when a battery lasts so long lol...)
You can in theory use those other chargers but the charge time will be significantly slower, probably double the time. I used my nexus one charger which I use to charge everything in my room and I got an error message saying that I needed a stronger charger. You may get that message as well on those 1A chargers. I have been successfully been able to use my 1.8A blackberry charger with success though as well as my 1.5A griffin at work but I shorted the pins on the cable I use on that charger.
Like I said you can maybe use those other chargers but you may get a power message. You're best off with the stock charger.
use everything. "Just don't use LG chargers"
regards
From what I understand through research, It doesn't matter at all. Stay around the official amp voltage range. If it is a bit high, the phone will regulate how much power it draws from the charger. If it is a bit lower, then expect slow charge.

Why not?
I am using a Galaxy S III charger, I guess I am not causing any harm with that... ?
You can use any charger that outputs at 5 volts. Even if the charger is 5 volts 10amps. The phone will only draw as mu current as its built to draw and no more than that.
Been using my s2 charger since I got my note 2 with no trouble at all. I also sometimes use my HTC desire charger and again no trouble here.

Hmm I thought changing the voltage makes the difference in how much power it draws (and puts into the battery) and the amp rating is how much power the charger is meant to give. So if the phone uses up 2 amps at 5 volts, then it could overheat a charger rated at 1A at 5 volts.
That's how powering something like LEDs works. If an LED is rated at drawing 700 ma at 3.3V, a power supply rated at 3.3V and 700 or higher will work - it could be rated at 2,000 at 3.3V and the LED would still draw 700. If you raised the voltage to 3.7V, then the LED would consume more than 700mA and would be brighter, if it's made to take the higher voltage.

This is correct. As long as you are using a standard USB charger, which will output 5v, you will be fine. The amperage will determine how fast your phone will charge. A charger with an output of 0.5A (500mAh) @ 5V, which is equal to 2.5 watts, will charge your phone slower than a 1A @ 5V (5 watt) charger.
No need to worry about hurting your phone with a higher amperage output. Your phone will only use as much current as it can handle. If it is rated to draw 900mAh @ 5V, doesn't matter if the charger can output 1A, 2A, or 5A, the phone will only draw a maximum 900mAh.
I bought some Palm microUSB charger during their liquidation. These days I dont even open the chargers for any phones I buy. Infuse, Xperia Ion, Focus, Exhibit, Note 1 all of them charge fine with it.

Hi
If the voltage output of a charger is less than 5V (let's say 4.5V), will this hurt the phone & battery?
Note 2 isn't that picky on charger.
I have several off-brand 5V 2-3A chargers and all of then just work fine.
Glad I'm not the only one using a random charger... The ones phones come with, the cords are entirely too short.

This is exactly what I am going to say.
Yes, its perfectly safe. I've used my iPad charger to charge my note 2 before, because it charges at 10 volts intsead of 5 so the phone charged faster.

I use whatever charger is available and fits. Have for YEARS. You guys worry too much about crap. It is just a phone, if it breaks, I'll buy a new one. Never had a problem though.
Using other device's charger is usually OK. But...
- An iPhone charger will work but because apple doesn't use the same standard to signal a USB charging port, you will be limited to 500mA (i.e. slow).
- Using another phone charger most of the time but because they are usally rated 1A instead of 2A it will charge slower.
The Note 2 seems to be quite picky about chargers and cables, for example, I couldn't get a full charge with cheap micro-USB cables from eBay and my old Nexus One charger. The best IMHO is a quality 5V charger that does at least 2A and follows the USB charging port convension of shorting D+ and D-.
More than 2A is not a problem because the device will only use as much as it needs. However if it is less, as the phone will try to pull 2A, the voltage will drop bellow the acceptable threshold. Usually the phone can adapt by charging slower but for some reason it didn't work with my Nexus One charger (1A).

pls keep ur n10 charger in safe place.

Last nite, I played dead trigger until battery warning indicated 4%.
But I still keep playing and suddenly the screen went black.
I think the battery is totally dried out at that time. So I used the following
charger but failed to charge even after 10min. Here's the charger:
1. 3rd party 5V 3A charger,liteon brand.
2. old nokia 0.5A charger.
3. original samsung note2 charger.
all those 3 charger works normall on my n10 before last nite.
and suddenly i think maybe i can try out the original charger of n10.
And it works!
So i wonder if samsung or google put special charger on the adapter?
Before we know anything furthur.pls put ur n10 charger in safe place.
I think most tablet chargers output a voltage of 12v. That might of kicked your battery back to life.

I've confirm the voltage of my n10 adapter. Which printed "5V 2A".
It probably just needed a certain amount of minimum battery voltage to function and show charging. I doubt if the OEM power supply is special in any way. The charging circuit is really inside the N10.

when i plug in the non-n10 charger, even after 10min,n10 is not able to boot. Only flaahing the battery charging symbol for 1 sec.
when i plug in the original charger, n10 can be boot instantly.
thats why i think it is very weird about the original charger. but other chargers still works well when n10 battery is NOT completely dried out.

Yeah, that is very strange indeed. It does draw in the 1800mA range from the battery during boot up. Are you using the same micro-USB cord all the time? It was reported that there are big differences in charging rate with different brands of cords.
This was covered in another thread recently.
Basicially the Samsung chargers have 2 pins shorted together to get full charging power of around 1.5A with the n10. Using other chargers will get you around 500ma output.
My guess is if you left your tablet on the "other" chargers overnight it would come on just fine. They simply don't output enough juice to power the tablet when the battery is that low.

Had you left the other chargers on long enough, the tablet would have booted fine. I've run into this. I have an old(er) Samsung Tab 2 10.1 charger I use with my N10 (now along with a Pogo cable) and my N10 charges rapidly. That, coupled with the two wires shorted out in Samy's setup for the larger amp's.....also, in my job, I work with other chargers all the time and use them all the time across multi platforms, to include my N10, and it charges fine (albeit much more slowly).

Should still work fine. Voltage is the same and the device will only draw as much amperage as needed. May have something to do with the circuitry in the charger? It may have been bad. As long as you don't supply more volts you are OK. More amps is also OK. Not enough amps will lead to burning up the charger unless the device is smart enough to realize its on a low amp charger (like the n10) and kick down so as not to over draw (ie - over drawing from the USB port which is a .5amp (500mAmp) or 1amp (1000mAmp)...someone correct me on the number here please)
The whole reason manufacturers tell you not to use someone else's charger is so you don't plug in, say, a 12 volt charger into a 5 volt item. That would pop something. That or some cheap charger poorly built could allow "dirty" power through causing problems. Both issues voiding warranties
Not sure if it's been mentioned, but depending on the usage of the tablet, you might not be able to charge it quicker than the power usage. For me, if I'm playing a demanding game at 1.7Ghz and max brightness, neither USB or Pogo can charge the tablet, and battery still drops (slower, but still drops).

Never seen anything burn up because of low amperage., power or watts generate heat and power(watts)=voltage x current.
Did you ever see a PS(charger is inside the N10) with a USB port that supplies anything but 5V? I haven't.
Current (amps) does the charging.
No USB charger will provide anything more than 5.1 volts. If the charging block has a USB plug look at the rating. Amperage for smaller devices may be 1a or even less. Newer big smartphones have bigger batteries and need more current to charge. My old Thunderbolt charger is 1A, the charger Motorola provides for my Maxx HD is 1.5A, the Samsung charger for my Galaxy Tab 2 7.0 is a 2 amp charger, so is the charger for the iPad that some frickin' jerk ripped off from my house. The Xoom escaped that problem by having a separate charge plug, not using the USB system, it 12 volts at 1.5 amps. See the pattern? A tablet of any kind has an even bigger battery and needs even more current to charge. The reason the N10 may lose charge even when plugged in is that the charger can't deliver the current needed to run the device and charge the battery simultaneously.
As I see it, Samsung and Google need to supply a slightly higher amperage power block to compensate for the use/charge balance problem. Our solution would be to turn it off and charge the device every night or even leave it plugged in when not in use.
Another thing is the surface area for current transfer. The USB points are tiny, the POGO Pins, dedicated to charging would be able to handle more current because they have more surface area.
Any one who knows better may correct me, I just ordered an N10 today from Google so my information here is what I have read here and what I know from years in the electronics field..

You don't need more current to charge a bigger battery, it's all about how long it will take to charge to full.
Some have stated that they've seen a 3A battery drain with certain games. The 9Ah battery would last approx. 3 hours which exceeds the max rate of the charging circuit and the PS. Even on a fully charged battery at that rate doesn't last that long.
AFAIK for any tablet to be able to draw 2A from any 5V charger (that can supply the needed amperage) the data pins (middle two pins from the use cable) have to be at 2.5V. Otherwise even if the charger is with correct specifications 5V/2A the tablet might not charge at all, or charge at a lower rate.

I forget the actual brand/model of the actual charging chip but if you poke around in the N10 files you can find it but it's specs are list as 2.5A max but N10's code limits it to 2.1A. This isn't the PS wall wart commonly called the "charger".
The recommended charging current for any lithium ion or lithium polymer is 0.7C. What that actually means is a current 0.7 x max capacity in mAh. For most phones e.g. my Galaxy Note 2 with a capacity of 3100 mAh this means a current at about 1.7A.
The battery Nexus 10, on the other hand, could very well be charged at a whooping 6.3A current.
In USB Battery Charging Specification 1.2 the maximum current a USB port can supply for charging purposes can be as high as 5A.
With the Perseus kernel for Note 2 you can actually specify the max limit for how much current the phone will draw from any charger.
So in theory.. it should be possible to charge the Nexus 10 with a 5V 5-6,3A charger.. and that would probably be very quick!
For the record: I havn't seen many (any?) chargers with more that 2.3A

Sure the charging rate is way under what it should be but as they use larger and larger capacity cells the only solution is a removable cell to charge by other means.

[Q] How much can the phone get charged maximum? can it handle 2A?

Hi,
I've got my phone with samsung's charger of 1A (bought it from an open store locally - it was the cheapest), so I ordered a Sony Ericsson charger of 1.5A which charges up much faster..
My question is, could it goes even faster?
I've seen some Galaxy Note 2 and S 4 charger of 2A like these:
http://www.ebay.com/itm/2A-USB-Wall...S_Cell_Phone_PDA_Chargers&hash=item5658d7a0bd
http://www.ebay.com/itm/OEM-2A-USB-...l_Phone_PDA_Chargers&var=&hash=item51aabf953a
Could our phone handle it and charge it with the whole 2A power? could it ruin the battery with that high Ampere?
I'm asking this because I've ordered a docking station like this:
http://www.ebay.com/itm/261247762140?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Which says 1.6A, so I was thinking perhaps theres stronger chargers out there for it..
Thanks!
im not sure about this but i believe the charger that comes with the phone is a 2 amp charger
It can handle 2A through USB port.
Via the charging dock, it can take 1.8A. Is that dock you are linking to an original part?
I have two DK26 docks and both say 1.8A, not 1.6A. Although if you connect a 2A charger to the dock, it'll be fine, it just won't be using the whole 2A input.

The Dock I've linked is a chinese copy, not the original, the one says 1.6A on description on Ebay, Does your original DK26 dock comes with charger too? What input and output is it says on each one? (picture could help much)
Also, how do you know it can handle 2A through USB? is that for sure?
Thanks for both!
The docks come barebone. No chargers included.
The charger included on the box of the phone is rated at 1.5A.
I have a Nexus 7 2A charger and an old Nokia 1.2A charger aside from the included 1.5A charger. All work fine either via USB or via the dock.
I can't notice any mayor difference on charging times, though. 1.2A charges almost as if not as fast as the 2A one. Iphone's 1A chargers do seem to take like 4 hours to charge the phone compared to the standard 2.5h I get from other higher rated wall chargers.
There are no 2A Sony chargers as of now.

I'm using a 2A as my car charger works perfect.

It should handel 2.A but I won't remand it. I don't think it's good for battery. But one thing is pretty sure. The phone will heat more up as the charging circuit have to dissipate more excess power. Can not affirm it as I don't exactly know it's made but I'm just saying...

The downside would be possibly shortening the usable life of your battery, because the higher amp charging will likely heat the battery to a higher temp.
There's no free lunch.
To me, waiting a bit longer for charging is worth it to ensure the longest charge cycle life, particularly since the battery is sealed into the device. If it was a cheap and easy replaceable battery, maybe.
Amps don't matter unless it is lower than the specification
Think about your car battery having 700amps but your car stereo is fused for 20amps. Your car stereo gets its power from the battery directly. There is no power regulation. Your device will take only what it needs. It won't effect the life of your battery. Think about the charger you plugged into the wall socket. A wall socket can generate enough current to melt metal. Lower power draw is cooler but really just make sure the voltage rating matches and the amp rating isn't too low. USB should be 5 volts anyways. The big issue with amperage, can the charger handle the draw? Example would be a 3000watt car amp drawing power from a 18 gauge speaker wire. It might work but the wire will heat up since it isn't designed to carry that much current.
In short for USB the charger amperage can be higher than the device needs but probably no less than 1/2 the rated amps for the device.
As above, you could plug in a 200A charger and the phone will still only draw the same current as from a 2A charger.
The amount of current drawn by the device is firmware controlled to protect the battery from heat damage.
The stock charger is 1.5A so the phone must draw no more than that.
It's all about cables too. I have a 2 amp TomTom charger hooked up to a 3 metre long USB cable but it charges slower than the standard 'in the box' charger Sony supply at 1.5 amp.
More cable and wrong core rating = more energy lost or wasted. I actually had to ask a sparky about this one, but it's true. Cable length, rating and core make all the difference.
For instance.
If you hooked up a 3 amp charger (I had one for an old phone) to a cable that can only handle 1 amp then you will only get 1 amp into the device, probably melt your cable too over time.
Honestly, the best bet is to use as near as dammit to the original rating on the included in the box charger. Electricity is a funny thing, it can screw your phone up in ways only time and noting the battery life will show.

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).

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/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
http://www.amazon.com/dp/B01706YAXY
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.......
